Tamarind (Tamarindus indica L.) Components as a Sustainable Replacement for Pork Meat in Frankfurter Sausages

Five types of frankfurters were formulated: a control without tamarind (T0) and four samples using 5% tamarind pulp paste (PT5), seeds (ST5), peel (CT5), and a blend of all of them (PSCT5), replacing the same portion of meat. The inclusion of tamarind components led to a reduction in the moisture and protein content of the reformulated frankfurters. In terms of mineral composition, CT5 showed the highest (p < 0.05) calcium content. Additionally, ST5 and CT5 treatments demonstrated the lowest processing loss values. The pH was lower in the PT5 treatment (p < 0.05). Incorporating tamarind components reduced the lightness (L*) of the frankfurters, resulting in darker sausages. However, ST5 exhibited greater redness (a*), while higher yellowness (b*) values were observed in PT5 and CT5 treatments (p < 0.05). Texture analysis revealed no differences (p > 0.05) in hardness and chewiness between T0 and PT5; however, ST5 exhibited the highest values for these parameters (p < 0.05). No variation in the conformational order of the lipid acyl chains due to the incorporation of tamarind compounds was observed related to physical entrapment of these compounds in the frankfurter matrix. Both T0 and PT5 were well accepted by consumers, and scores higher than 7 were observed for overall acceptability and purchase intention. The study demonstrated that incorporating tamarind components, especially pulp paste (PT), is a viable alternative for replacing lean pork meat in frankfurters, improving the sustainable aspects of frankfurter production.

Consumer animal welfare and healthy perception of fresh sausages' fiber fat replaced and elaborated with meat from non-castrated male pigs

Although replacement of fat with fiber is a good strategy to avoid boar taint on high-fat content products, as sausages, the final purchase intention is related to other external factors such as welfare and healthiness. So, the aim of this study was to evaluate the consumers' perception of sausages with fat replaced by fiber, elaborated with meat from non-castrated male pigs, and to determine the influence of the consumers' habits and demographic parameters on their beliefs related to pig castration. An online survey was carried out. A total of 131 consumers answered a questionnaire about habits and beliefs related to meat and meat product issues. Subsequently, they evaluated four images of labeled products (castrated-not castrated/normal-reduced-fat/traditional-high fiber content) with the Check-all-that-apply (CATA) test. In all, 87.7% of meat consumers perceived meat products as positive, although 71% trimmed the fat previous consumption. In a 9-point agreement scale, "Animal welfare worries me" obtained 7.5 and "the castration without anaesthesia should not be performed" 7.4. There was a higher grade of agreement with "castration of pigs justification to improve smell a flavour" in primary education level and in rural residence (p < .05). Sausages from castrated animals were perceived as fatty, juicy, appetizing, and animal cruelty. Reduced-fat and rich/high fiber sausages were not associated with "healthy" but with "expensive" and "unpleasant." Although reduced-fat entire male pork sausages with vegetable fiber could be a better option for marketing uncastrated male pork, they will need more than fiber claims to be associated with healthy products and the consumer should be previously informed if he could appreciate the meaning of castration labeling.

The Effects of Nutrition and Health Claim Information on Consumers’ Sensory Preferences and Willingness to Pay

As marketing tools, nutrition claims (NCs) and health claims (HCs) can be used to convey the nutritional properties and health benefits of food to consumers, but their respective effects on consumers’ perceptions of healthier meat products are inconsistent in the literature. Using a physical prototype of omega-3-enriched sausages as a research interest, this paper explores how HCs and NCs differently influence consumers’ sensory preferences and willingness to pay (WTP). Sensory tests were carried out among 330 participants, followed by a choice-based conjoint (CBC) experiment to measure consumers’ WTP. Results indicate that, in comparison with the uninformed condition, labeling an omega-3 nutrition claim increased consumers’ sensory liking for omega-3-enriched sausages in the attributes of appearance and texture. Moreover, consumers were willing to pay more for healthier sausages, but labeling HCs did not significantly improve participants’ WTP for omega-3-enriched sausages more than NCs. Hence, HCs did not significantly outperform NCs, when it comes to positively influencing consumers’ sensory liking and paying intentions for omega-3-enriched sausages. The findings of this study have implications for the meat industry in developing healthier sausage formulations with greater likelihood of success in the market.

Understanding the role of information and taste heterogeneity in consumer preferences for functional beef: The case of the omega-3 enriched burger

Beef demand has progressively decreased due to an increasing number of consumers who perceive beef as harmful to their health, among other causes. In contrast, functional foods are one of the fastest-growing markets. This study aims to analyse consumer preferences and estimates the willingness to pay for beef enriched with omega-3 fatty acids. We intend to identify and profile the potential market segments for functional beef and determine how the provision of information can affect consumer preferences. Data have been collected by applying a choice experiment on a sample of 757 Italian beef purchasers. The sample was randomly split into two information treatments plus a control group. Participants in the information treatments were given an explanation about the functional meat production system. Results showed that the average consumer has a preference for ω-3 enrichment and that information about the food's production process increases this preference. Therefore, the study reveals the existence of a potentially profitable market for functional beef.

Factors that predict consumer acceptance of enriched processed meats

The study aimed to understand predictors of consumers' purchase intention towards processed meat based functional foods (i.e. enriched processed meat). A cross-sectional survey was conducted with 486 processed meat consumers in spring 2016. Results showed that processed meats were perceived differently in healthiness, with sausage-type products perceived less healthy than cured meat products. Consumers were in general more uncertain than positive about enriched processed meat but differences existed in terms of the attitudes and purchase intention. Following regression analysis, consumers' purchase intention towards enriched processed meat was primarily driven by their attitudes towards the product concept. Perceived healthiness of existing products and eating frequency of processed meat were also positively associated with the purchase intention. Other factors such as general food choice motives, socio-demographic characteristics, consumer health and the consumption of functional foods and dietary supplements in general, were not significant predictors of the purchase intention for enriched processed meat.

Effect of Gleditsia sinensis Lam. Extract on Physico-Chemical Properties of Emulsion-Type Pork Sausages

This study was performed to investigate the effect of Gleditsia sinensis Lam. extract on the physicochemical properties of emulsion-type pork sausages during storage at 10°C for 4 wk. Treatments were as follows: (C, control; T1, sodium ascorbate 0.05%; T2, Gleditsia sinensis Lam. 0.05%; T3, Gleditsia sinensis Lam. 0.1%; T4, Gleditsia sinensis Lam. 0.2%; T5, Gleditsia sinensis Lam. 0.1% + sodium ascorbate 0.05%). The values of pH, moisture content, lightness, redness, and sensory attributes were all significantly decreased, while the yellowness, chroma, hue angle, and texture properties were increased during storage with increase of the Gleditsia sinensis Lam. extract added. In addition, the antioxidant activity and antimicrobial activity in the sausages displayed significant increases (p<0.05). Therefore, although it was concluded that the addition of Gleditsia sinensis Lam. extract is not effective for improvement of the physical properties compared to chemical additives in sausages, it could be applied to meat products as a natural preservatives.

Deciphering the consumer behaviour facets of functional foods: A literature review

This paper presents a systematic literature review of studies investigating various facets of consumer behaviour towards functional foods. It focuses on published international research on functional food attitude and behaviour from across the world. Research papers (n = 112) that were identified were coded in terms of study type, variables studied, product type, participant profile, research methodology and analysis details, as well as results and implications for future research. Results provide a systematic overview of the context in which behaviour towards functional foods have been examined in the past and provide a synthesis of findings in four categories of determinants, namely (1) Personal Factors, (2) Psychological Factors, (3) Cultural & Social Factors, and (4) Factors relating to the functional food product. A reference model for the relationships between these factors and behaviour of consumers is derived.

Consumer attitude and purchase intention towards processed meat products with natural compounds and a reduced level of nitrite

This study investigates consumer attitude and purchase intention towards processed meat products with added natural compounds and a reduced level of nitrite. The rationale for such innovation relates to nitrite's negative health image as a chemical additive among consumers, versus the perception of compounds from fruits and vegetables as being natural and healthy. Cross-sectional data were collected through online questionnaires on knowledge about, interest in, attitude and intentions towards such new type of processed meat products in Belgium, The Netherlands, Italy and Germany (n=2057). Consumers generally had limited knowledge about nitrite being added to meat products. Yet, they expressed favourable attitudes and purchase intentions towards the new processed meat products. Purchase intention associated positively with: attitude; preference for natural over chemical additives; perceived harmfulness of chemical additives; risk importance; domain specific innovativeness; awareness of nitrite added; education; general health interest; and processed meat consumption frequency. Consumers from Italy and Germany had a lower level of purchase intention compared to Belgium. Four consumer segments were identified based on attitude and purchase intention: 'enthusiasts' (39.3% of the sample), 'accepters' (11.9%), 'half-hearted' (42.3%) and 'uninterested' (6.6%). This study provides valuable insight for further product development and effective tailoring of marketing communication strategies of innovative processed meat products.
