Barriers to consumption of plant-based beverages: A comparison of product users and non-users on emotional, conceptual, situational, conative and psychographic variables

Shifting Herbal Knowledge: The Ecological and Cultural Dynamics Behind Plant Use Changes in the Southern Occitan Alps

This study examines changes in medicinal and wild food plant knowledge in the Alpine Southern Occitan area, focusing on temporal and cultural shifts. Drawing from ethnobotanical data from the Maira Valley (1970, 2022), Stura Valley (2004), and Grana Valley (2011), we explore dynamics in plant use and how they may have been generated by ecological, socio-economic, and cultural changes. A total of 308 plant taxa were recorded, with notable declines in Asteraceae and Lamiaceae utilizations by 2022, suggesting a remarkable erosion of traditional ecological knowledge (TEK). Conversely, the use of families like Brassicaceae and Amaranthaceae increased, possibly due to socio-economic factors. This study also found in recent years a decrease in medicinal plant uses and a greater reliance on food system-related plants. Logistic regression models highlighted altitude (600-1600 masl) as a key factor in plant diversity use, with older participants showing more diverse ethnobotanical knowledge. This study underscores the resilience and transformation of plant knowledge in response to socio-economic and environmental changes in the Alpine area.

Consumer evaluations of commercially available plant-based cheddar cheese alternatives reveal inferior taste, nutrition and emotional appeal

Many people in the Western world wish to reduce dietary reliance on animal-based and animal-derived foods. Plant-based (PB) meat and dairy alternatives can aid in this transition, but in the dairy category, only the milk market is well developed. Attention in the present research is, therefore, directed to PB cheese alternatives (PBCA), which were studied relative to dairy cheeses in a consumer taste test (central location setting) with 157 New Zealand (NZ) consumers conducted in 2023. Five commercial semi-hard cheeses from cow's milk and three commercial PBCAs in the cheddar style were tested. All samples were presented blind, and a multi-response measurement paradigm (hedonic, sensory, emotional, conceptual, situational, attitudinal) was used. Results showed that, without major exception, all PBCAs had lower liking ratings, inferior sensory, emotional and conceptual characterisations and poorer attitudinal and situational use evaluations than their dairy counterparts. Further, all of the PBCAs were rated similarly, as contrasted with the dairy cheese samples, which were differentiated based on textural and flavour attributes, liking and non-sensory characterisations. It was concluded that, as a whole, PBCAs in the 2023 NZ market were poorly accepted by consumers, suggesting that much more research and consumer-focused product development is needed before these products offer consumers suitable choices if they seek to transition from an animal-based to a PB diet.

Zero alcohol products and adolescents: A tool for harm reduction or a trojan horse?

INTRODUCTION

Zero alcohol products (ZAPs) could reduce alcohol-related harms by acting as a substitute for alcoholic beverages. However, concerns have been raised regarding the potential for these products to expose young people to additional alcohol-related stimuli, further normalising alcohol use and acting as a gateway to underage alcohol consumption. Scarce research has examined whether these concerns are warranted.

METHOD

This project comprised two parts involving Australian adolescents aged 15-17 years. Part 1 was a series of 5 online focus groups (n = 44) that provided initial insights into perceptions of and experiences with ZAPs. Part 2 was a national online survey (n = 679) that assessed the generalisability of the focus group findings and identified factors associated with ZAP-related attitudinal and behavioural outcomes.

RESULTS

ZAPs were found to be salient and attractive to Australian adolescents. Over a third of surveyed adolescents (37%) had tried ZAPs. The focus group participants and survey respondents generally perceived ZAPs in a positive light, seeing them as a useful alternative to alcohol for both adolescents and adults who want to circumvent social expectations to use alcohol. Some of the study participants acknowledged the potential for ZAPs to serve as a gateway to alcohol use and recommended reducing their visibility and accessibility.

CONCLUSION

ZAPs are likely exposing minors to additional alcohol-related stimuli potentially increasing their risk of underage alcohol consumption. Regulatory responses to ZAPS need to protect young people from the potential adverse consequences of ZAPs exposure while enabling the products to be used by adults as an alcohol substitute.

The impact of plant-based product denomination on consumer expectations and sensory perception: A study with vegan chocolate dessert

In recent years, there has been a growing demand for plant-based products from omnivorous consumers seeking a healthier and more sustainable diet, but sensory issues can still impact the consumption experience. Since food denomination and labeling can play a crucial role in consumer expectation and perception, investigating these interactions is essential. Thus, this study investigated the influence of plant-based product denominations on consumer expectations and sensory perceptions. Using descriptive and affective sensory analysis methods, the response of 300 untrained consumers to three variations of product denomination for the same sample of vegan chocolate dessert was evaluated: Vegan Chocolate Mousse (VCM), Chocolate Mousse (CM), and Creamy Coconut Dessert with Cacao (CCDC). The results indicated that the attributes expected by consumers for each denomination did not always correspond to the actual perceptions, particularly in terms of taste and aroma. The attributes highlighted in the consumption expectation varied among the sales denominations, although the perceived attributes did not significantly differ between the names. Furthermore, the addition of the term "vegan" in the name contributed to a greater correspondence between expectation and consumption reality, although the acceptance score did not significantly differ between the denominations. It was also noted that the term "mousse" did not adequately reflect the texture of the products, prompting consumers to suggest replacing the term with "cream." The study reinforces the importance of transparent and informative labeling strategies to promote the acceptance of plant-based foods, thereby encouraging increased consumption frequency of plant-based analogs by non-restricted diet consumers, resulting in a better consumption experience.

Addressing concerns about sustainability and animal welfare: Investigating consumers' adoption and behavioral intention towards plant-based eggs

This study aimed to address the concerns regarding sustainability and animal welfare that have led to egg shortages. By examining consumer adoption and purchase intention towards plant-based eggs as a viable alternative, this study identifies the key factors influencing consumer interest. The study integrates the Theory of Planned Behavior (TPB) and Value-Attitude-Behavior (VAB) frameworks. Data from 239 responses were collected through a questionnaire survey and analyzed using SPSS 27.0 and AMOS 28.0. The results highlight the significant impact of intrinsic food value and sensory appeal on purchase intention. Attitude, subjective norms, and perceived behavioral control mediate the relationship between food value and purchase intention. The findings of this study provide valuable insights for food industry professionals by enabling them to develop targeted strategies. Moreover, this study emphasizes plant-based eggs as a sustainable and health-conscious solution to egg shortages, thereby promoting overall industry sustainability.

Milking the Alternatives: Understanding Coffee Consumers' Preferences for Non-Dairy Milk

Consumer interest in plant-based milk alternatives is growing, despite extra charges in coffeehouses. While much research exists on non-dairy alternatives, plant-based milks in coffee drinks remain understudied. This study examines consumer preferences and behaviors regarding milk alternatives in coffee, using the Theoretical Domains Framework (TDF) and the Behavior Change Wheel (BCW). A survey of 200 participants from 19 countries explored demographics, coffee habits, attitudes towards non-dairy milk charges, and marketing awareness. Market insights showed taste as the main reason for coffee choice, with a preference for cow's milk and local cafes for quality. Many opposed the extra charges for non-dairy options, citing lactose intolerance or allergies, especially among Gen Z and Millennials. Regional variations included stronger opposition in the UK and Germany compared to the UAE and USA. The marketing for non-dairy milk was less memorable than general coffee advertisements. Regression analysis confirmed that viewing non-dairy milk as a dietary staple increased consumption, aligning with the TDF's "Beliefs about Consequences" domain. Finally, within the BCW framework, the intervention strategies centered on training and coercion were discussed. Implementing these approaches could encourage the wider adoption of non-dairy milk options in coffee shops, fostering inclusivity, health awareness, and supporting environmental sustainability efforts.

Driving Factors Influencing the Decision to Purchase Plant-Based Beverages: A Sample from Türkiye

In recent years, the trend toward plant-based beverages has continued to grow rapidly. This study aimed to assess the effects of sociodemographic characteristics and knowledge about plant-based beverages, subjective norms, perceived price, environmental protection, animal welfare, availability, and trust on attitudes and buying behavior toward these products. This study was conducted online using a two-part questionnaire prepared by considering the literature. This study included 935 participants, and our findings confirmed that the variable of environmental protection affects the attitude toward these products (β= 0.095; p = 0.007). Furthermore, gender, income level, lactose intolerance, and bloating due to cow's or sheep's milk influenced actual buying behavior (p < 0.05; p < 0.001). These findings indicate that people's increased environmental protection awareness will positively influence attitudes towards plant-based beverages and that individuals who do not experience lactose intolerance and bloating due to cow's or goat's milk will have lower actual buying behavior. It was also determined that individuals with lower incomes bought more plant-based beverages. In conclusion, plant-based beverage marketers need to take into account individuals' sociodemographic characteristics and environmental protection awareness when planning their marketing strategies.

Investigation into the Sensory Properties of Plant-Based Eggs, as Well as Acceptance, Emotional Response, and Use

Consumers have become interested in plant-based alternatives to animal-based products. One of the under-studied alternatives is plant-based eggs (PBEs). This research investigated PBEs relative to conventional eggs and tofu scramble-another plant-based alternative. Firstly, participants (n = 93) completed a word association task asking them about PBEs. Participants then evaluated the different food samples using hedonic scales, check-all-that-apply (CATA), and temporal check-all-that-apply (TCATA), as well as identified their emotional response and proposed use for PBEs. Participants were interested in plant-based alternatives, including PBEs, but they were concerned about the sensory properties. When they evaluated the different samples, the flavour and texture of the PBEs were disliked in comparison to the eggs. This result may be due to the beany, bitterness, and off-flavour attributes associated with the PBEs. Participants also associated the PBEs with negative emotions. The liking of tofu scramble was not significantly different from the eggs, and the eggs and tofu scramble were mainly associated with positive emotions. During the TCATA evaluation, the participants focused on the flavour attributes of PBEs, while their evaluation of the eggs was dominated by the textural attributes. Whether following a plant-based diet or not, consumers are interested in PBEs, but the sensory properties of PBEs need to be improved before they are willing to adopt them into their diet. This study is one of the first to evaluate the sensory properties of PBEs, as well as consumers' emotional response to them and their attitudes about PBEs.

Association between Beverage Consumption and Environmental Sustainability in an Adult Population with Metabolic Syndrome

Beverages are an important part of the diet, but their environmental impact has been scarcely assessed. The aim of this study was to assess how changes in beverage consumption over a one-year period can impact the environmental sustainability of the diet. This is a one-year longitudinal study of 55-75-year-old participants with metabolic syndrome (n = 1122) within the frame of the PREDIMED-Plus study. Food and beverage intake were assessed using a validated food frequency questionnaire and a validated beverage-specific questionnaire. The Agribalyse® 3.0.1 database was used to calculate environmental impact parameters such as greenhouse gas emission, energy, water, and land use. A sustainability beverage score was created by considering the evaluated environmental markers. A higher beverage sustainability score was obtained when decreasing the consumption of bottled water, natural and packed fruit juice, milk, and drinkable dairy, soups and broths, sorbets and jellies, soft drinks, tea without sugar, beer (with and without alcohol), and wine, as well as when increasing the consumption of tap water and coffee with milk and without sugar. Beverage consumption should be considered when assessing the environmental impact of a diet. Trial registration: ISRCTN, ISRCTN89898870. Registered 5 September 2013.

Sensory characteristics of plant-based milk alternatives: Product characterisation by consumers and drivers of liking

Like other plant-based (PB) product categories, PB milk alternatives (PBMA) are in ascendency as part of the green consumer transition and a greater focus on personal health. However, consumption remains far below that for cow's milk, and among multiple barriers to uptake, inferior sensory properties is one problem, nutritional inadequacies another. While exceptions exist in both instances, a general need for improved products remains. The present research is situated in this nexus, and its primary aim was to contribute new consumer-centric insight regarding the sensory drivers of liking/disliking in the PBMA category. This was achieved through a central location study with adult New Zealanders (n = 143, not regular PBMA consumers) who tasted 18 different PBMA samples spanning a broad range of PB ingredients (soy, oat, coconut, almond, rice, cashew, peanut, macadamia, lentil, hemp, sesame) in different product types (single PB source, blends, barista style) with varying nutritional profiles. The most liked sample (6.5/9), which was made from soy, had the nutritional profile that most approximated cow's milk (3 g/100 mL protein), as well as a milky appearance and taste. Its mouthfeel was smooth, and this sensory characteristic was also paramount for barista-style PBMAs being well-liked (>5.9/9) regardless of their constituent PB ingredient (oat, almond, coconut). Opportunities for product innovation within this type of PBMA was identified including for using barista-style beyond hot beverages, as these samples received positive liking scores on average. The same applied to blends as multiple-source PBMAs can facilitate improved nutritional composition, and significant scope seemed to exist to identify more liked vs less liked PB ingredient combinations (e.g., almond/rice vs coconut/sesame). By identifying, through penalty/lift analysis that positive sensory drivers of PBMA liking span all sensory modalities (appearance, taste, flavour, texture and mouthfeel), it becomes easier to appreciate that products in this category are complex and challenging to optimise. A second minor research aim was focused on the modulating influence of PBMA consumption frequency on product liking and the sensory drivers of liking. The key result was a positive association between liking and higher consumption frequency, and greater appreciation of sweet, coconut, nutty and cereal/oaty characteristics of PBMAs.

Plant-Based Alternatives Need Not Be Inferior: Findings from a Sensory and Consumer Research Case Study with Cream Cheese

Reliance on animal foods must be reduced to improve planetary and human well-being. This research studied plant-based cheese alternatives (PBCA) relative to dairy cheese in a consumer taste test with 157 consumers in New Zealand. A case study approach used cream cheese (commercially available) as the focal product category (2 PBCA, 2 dairy) and implemented a multi-response paradigm (hedonic, sensory, emotional, conceptual, situational). "Beyond liking" insights were established, including drivers of liking (sensory, non-sensory) and sensory drivers of non-sensory product associations. Two consumer segments were identified, of which the largest (n = 111) liked PBCA and dairy samples equally (6.5-6.7 of 9). In this PBCA Likers cluster, the key sensory drivers of liking were 'creamy/smooth mouthfeel', 'dissolves quickly in mouth', and 'sweet', while a significant penalty was associated with 'mild/bland flavour'. The non-sensory data contributed additional consumer insights, including the four samples being perceived as differently appropriate for 9 of 12 use situations, with PBCA being regarded as less appropriate. In the limited confines of this case on cream cheese, the findings show that PBCA need not be inferior to their dairy counterparts despite a general narrative to the contrary. Of note, the results were obtained among participants who were open to eating a more PB diet but were not vegetarian or vegan.

Effects of different strains fermentation on the sensory and nutritional properties of soy-based yogurt

BACKGROUND

Soy protein is the only full plant protein that is comparable to animal protein. Soy whey contains a variety of nutrients including isoflavones and oligosaccharides. Additionally, different strains have profound influence on functional metabolism. Most prospective studies used mixed strain fermented yogurt, but few studies on single strain fermented yogurt. The present study aimed to ferment nutritious and healthy soy-based yogurt using a single strain and to provide technical support for the reuse of soy whey.

RESULTS

Streptococcus salivarius subsp. thermophilus HCS07-002, Bifidobacterium animalis subsp. lactis HCS04-001 and Lactiplantibacillus plantarum HCS03-084 had strong growth and metabolic activities. Bifidobacterium animalis subsp. lactis HCS04-001 fermentation raised the texture and rheological properties of yogurt and enriched the flavor substances in the yogurt, resulting in a good quality soy-based yogurt. The contents of arginine, glutamic and proline were greatly affected by the fermentation of different strains. The fermentation of B. animalis subsp. lactis HCS04-001 was beneficial to the enrichment of soy isoflavone and equol in yogurt, and enhanced antioxidant activity of yogurt.

CONCLUSION

Our findings indicated that yogurt fermented with B. animalis subsp. lactis HCS04-001 had the best sensory and nutritional properties, which provides valuable insights into the selection of suitable strains to improve the quality and nutritional value of plant yogurt. © 2023 Society of Chemical Industry.

Consumer acceptance for sheep milk-based yogurt-Evidence from a large sample of Italian consumers

Testing consumer acceptance for a new product, such as the sheep milk-based yogurt, provides a measure of its market success, thus it informs producers on the effectiveness of their decision to transform sheep milk into yogurt to increase their revenues. This work explores to what extent consumers accept sheep milk-based yogurt and tests the role of personal-related factors and product-related features on shaping its acceptance. The study collects data from a representative sample of Italian yogurt consumers, and data are then analyzed via a logistic regression. Results show that male, highly educated, and high-income consumers are more likely than others to accept sheep milk-based yogurt. Findings suggest that consumers' food neophobia and variety seeking traits play a pivotal role in affecting consumer acceptance. Lastly, interest in nutritional and health-related yogurt features increases the probability of accepting sheep milk-based yogurt. Thus, sheep milk-based yogurt should be targeted at high-end male consumers and those interested in nutritional and health-related aspects of yogurt. Informing consumers about the sheep milk yogurt properties may further increase its acceptance and curb food neophobia, which we found to be one of the main barriers for the product acceptance. Future studies will explore consumer acceptance by using a real product and taste experiments.

Smoothies Marketed in Spain: Are They Complying with Labeling Legislation?

There is no legal definition of a smoothie, so the European legislation applicable to its labeling is that of fruit juice. The smoothie market has grown in recent years, as it can include a wide variety of ingredients: fruits, fruit purees, honey, milk and vegetable milks, vegetables, herbs, cereals, cereal flours, seaweed, and crushed ice. In this study, 57 smoothies were reviewed. All of them were purchased in supermarkets and classified into eight types according to the main ingredients. Fifteen legal statements/items were reviewed on the pack labels: eleven mandatory and three optional. Moreover, nutrition labels, nutritional claims, images, marks, and other symbols were also reviewed. Only 22.8% of the samples complied with EU and Spanish labeling legislation. More incorrectness was related to the name of the food and the fruits included as main ingredients; other errors related to the allergy/intolerance statements, and some nutritional claims concerning vitamin C were also detected to a lesser extent. General advice is provided for consumers to interpret smoothie labels correctly. Lawmakers should amend legislation to accept the term "smoothie" as a legal name.

A Prospective Review of the Sensory Properties of Plant-Based Dairy and Meat Alternatives with a Focus on Texture

Consumers are interested in plant-based alternatives (PBAs) to dairy and meat products, and as such, the food industry is responding by developing a variety of different plant-based food items. For these products to be successful, their textural properties must be acceptable to consumers. These textural properties need to be thoroughly investigated using different sensory methodologies to ensure consumer satisfaction. This review paper aims to summarize the various textural properties of PBAs, as well as to discuss the sensory methodologies that can be used in future studies of PBAs. PBAs to meat have been formulated using a variety of production technologies, but these products still have textural properties that differ from animal-based products. Most dairy and meat alternatives attempt to mimic their conventional counterparts, yet sensory trials rarely compare the PBAs to their meat or dairy counterparts. While most studies rely on consumers to investigate the acceptability of their products' textural properties, future studies should include dynamic sensory methodologies, and attribute diagnostics questions to help product developers characterize the key sensory properties of their products. Studies should also indicate whether the product is meant to mimic a conventional product and should define the target consumer segment (ex. flexitarian, vegan) for the product. The importance of textural properties to PBAs is repeatedly mentioned in the literature and thus should be thoroughly investigated using robust sensory methodologies.

“Got Milk Alternatives?” Understanding Key Factors Determining U.S. Consumers’ Willingness to Pay for Plant-Based Milk Alternatives

Milk is an important dairy product in U.S. food retail. Lifestyle changes toward climate-conscious consumption, animal welfare, and food safety concerns have increased the popularity of plant-based milk alternatives. This study is focused on such beverages and provides insights and best practice recommendations for marketing managers in the U.S. food retail sector. An online survey was distributed to explore factors explaining the intentions of U.S. consumers to purchase and pay a premium for plant-based milk alternatives. Food curiosity and food price inflation were identified as relevant for both willingness to buy and willingness to pay a price premium. In addition, animal welfare concerns and the green and clean product image of plant-based alternatives were relevant to the willingness to pay a premium for plant-based milk.

Consumer perception of plant-based yoghurt: Sensory drivers of liking and emotional, holistic and conceptual associations

Plant-based (PB) yoghurts is a rapidly expanding food category with the potential to reduce many of the negative environmental impacts associated with the farming of dairy cattle and related greenhouse gas emissions. Within the context of growing consumer demand for PB products, this research aimed to identify the main drivers of consumer acceptance of PB yoghurts through data drawn from a consumer study of 113 adult New Zealand participants who tasted a representative range of commercially available vanilla-flavoured PB yoghurts, and provided sample evaluations using a multi-variable measurement approach comprised of liking ratings, emotional responses, sensory characterisations, and holistic / conceptual perceptions. The primary finding of this study was that the overall acceptability of currently available PB yoghurts is low, leading to poor attitudes and low willingness to consume PB yoghurts. The examined products were characterised by the presence of several sensory attributes that negatively impacted consumer liking, either because they were unexpected or because their intensity level was too high. Among the main sensory issues identified were perceived sourness (acidity), lumpy appearance and non-white colour. In contrast, vanilla flavour and a creamy/smooth texture were identified as the main drivers of liking. The multi-response approach used in this study enabled a comprehensive characterisation of the products. One of the key insights gained was that negative emotional activation, caused by the presence of unexpected sensory attributes in the samples, was the main driver of product rejection. This was likely due to the disparity between consumers' sensory expectations, formed primarily based on their experience with dairy yoghurts, and the actual experience upon tasting the PB yoghurts. Overall, the findings indicate that the sensory properties of currently available PB yoghurts are a significant barrier to their adoption by most consumers and that addressing these sensory deficiencies is essential to achieving mainstream market acceptance of these products.

Perceptions toward Plant-Based Milk Alternatives among Young Adult Consumers and Non-Consumers in Denmark: An Exploratory Study

The objective of this study was to determine associations among plant-based milk alternatives (PBMAs), sources of information on the PBMAs used, and the consumption of PBMAs among Danish young adult consumers and non-consumers of PBMAs. An online survey was conducted in May 2019. A total of 341 participants (consumers: n = 171; non-consumers: n = 170) aged 16-35 years old completed the survey. Most consumers drank less than one glass of PBMAs per week, and oat drink was the most frequently consumed PBMAs. Oat drinks were primarily consumed with coffee/tea or porridge, while soy drinks were preferred to be consumed alone. Participants who perceived PBMAs as natural, good for health, tasty, or nutritionally equal to cow's milk were more likely to be consumers of PBMAs. Additionally, participants who perceived PBMAs as highly processed or artificial were less likely to be consumers of PBMAs. For consumers, the most used sources of information on PBMAs were package labeling, followed by social media. The study´s results can help to improve marketing campaigns concerning the Danish retail of PBMA, whereby nutritional and sensory characteristics of PBMAs are highlighted through social networks and marketing strategies with product package labeling.

Consumer Preference Segments for Plant-Based Foods: The Role of Product Category

A survey of willingness to consume (WTC) 5 types of plant-based (PB) food was conducted in USA, Australia, Singapore and India (n = 2494). In addition to WTC, emotional, conceptual and situational use characterizations were obtained. Results showed a number of distinct clusters of consumers with different patterns of WTC for PB foods within different food categories. A large group of consumers did not discriminate among PB foods across the various food categories. Six smaller, but distinct clusters of consumers had specific patterns of WTC across the examined food categories. In general, PB Milk and, to a much lesser extent, PB Cheese had highest WTC ratings. PB Fish had the lowest WTC, and two PB meat products had intermediate WTC. Emotional, conceptual and situational use characterizations exerted significant lifts/penalties on WTC. No penalty or lifts were imparted on WTC by the situational use of 'moving my diet in a sustainable direction', whereas uses related to 'when I want something I like' and 'when I want something healthy' generally imparted WTC lifts across clusters and food categories. The importance of this research for the study of PB foods is its demonstration that consumers are not monolithic in their willingness to consume these foods and that WTC is often a function of the food category of the PB food.

Plant-Based Only: Investigating Consumers' Sensory Perception, Motivation, and Knowledge of Different Plant-Based Alternative Products on the Market

Consumer acceptance and product development of sustainable, healthy, and tasty plant-based alternative products (PBAPs) are closely interlinked. However, information on consumer perceptions of the sensory profile of plant-based meat, cheese, and milk remains scarce. The study aimed to investigate German consumers’ (1) sensory evaluation of PBAPs and (2) consumers´ motivations and knowledge underlying the purchase of such products. This was analyzed in relation to different dietary styles of consumers (omnivore, flexitarian, vegetarian, vegan). A sample of 159 adults completed two tasks: first, a sensory test in which participants tasted and rated three different PBAPs in two consecutive sessions, and second, a questionnaire on consumption behavior, motivation, and knowledge. Results show few differences between nutrition styles in sensory evaluation of individual product attributes. However, overall liking was rated significantly higher by vegans than by omnivores. All dietary styles reported animal welfare and environmental aspects as the main motivations for consuming PBAPs. Most participants acknowledged that meat and cheese alternatives are highly processed foods and not a fad but are not automatically healthier or more environmentally friendly than their animal-based counterparts. Future research should focus on emerging product segments such as plant-based cheeses to better understand how consumers evaluate PBAPs.

Speciation of Arsenic(III) and Arsenic(V) in Plant-Based Drinks

Recently, food products based only on plants have become increasingly popular and are often found on store shelves. It is a specific market response to the growing demand for, and interest in, plant foods. Cow's milk has also gained its counterpart in the form of plant-based beverages, based on cereals, nuts or legumes. The emergence of an increasingly wide range of plant-based food products has also led to increased research on safe plant food consumption. This study was conducted to quantify total arsenic content and its species (arsenic(III) and (V)) in samples of plant-based beverages purchased at Polish markets. Speciation analysis of arsenic was performed by high-performance liquid chromatography combined with inductively coupled plasma mass spectrometry. The presented study was conducted on six selected plant-based beverages, including almond, millet, soybean, rice, coconut and oat. An analysis using size exclusion chromatography was performed. In order to initially visualize the content of the observed elements and the particle size of the compounds in which they occur, at first the samples were subjected to the size-exclusion chromatography. Speciation analysis of arsenic was carried out using anion-exchange liquid chromatography, combined with inductively coupled plasma mass spectrometry. The presented method was validated with certified reference material (CRM rice flour).

Fermentation of plant-based dairy alternatives by lactic acid bacteria

Ethical, environmental and health concerns around dairy products are driving a fast‐growing industry for plant‐based dairy alternatives, but undesirable flavours and textures in available products are limiting their uptake into the mainstream. The molecular processes initiated during fermentation by lactic acid bacteria in dairy products is well understood, such as proteolysis of caseins into peptides and amino acids, and the utilisation of carbohydrates to form lactic acid and exopolysaccharides. These processes are fundamental to developing the flavour and texture of fermented dairy products like cheese and yoghurt, yet how these processes work in plant‐based alternatives is poorly understood. With this knowledge, bespoke fermentative processes could be engineered for specific food qualities in plant‐based foods. This review will provide an overview of recent research that reveals how fermentation occurs in plant‐based milk, with a focus on how differences in plant proteins and carbohydrate structure affect how they undergo the fermentation process. The practical aspects of how this knowledge has been used to develop plant‐based cheeses and yoghurts is also discussed.

The Use of Demographics and Psychographics to Study Product Effects with Nutrient Supplements: Exploratory Multi-Country Data

Demographics and psychographics are used to study the influence of different consumers on product effects in food development and testing. Demographics have a longer history and are routinely used in most research; psychographics are more recent, raising the question of whether they add to research on food products. The research presented here represents extensive exploratory data that demonstrate that both demographic measures and psychographic measures add to our understanding of consumer's liking ratings for nutrient supplements. The results are discussed in the context of broader research on a range of food products. In addition, the research reported here was conducted in four different countries, demonstrating many country effects. Finally, tests were conducted with users of the products, lapsed users of the product, and users of other nutrient supplements (non-users), and this led to many differences in product testing. These results further suggest that age and gender are not the only demographic variables to be studied, along with psychographic variables. The psychographic variables should be selected for a particular product category under investigation, as effects of specific psychographic measures vary for product categories. Specific variables do not fit all products for both demographics and psychographics.
