Consumers' trust in vegetable supply chain members and their behavioural responses: A study based in Queensland, Australia

Segmentation of Consumer Preferences for Vegetables Produced in Areas Depressed by Drought

The megadrought in Chile’s north and central zones has impacted the horticultural production of family farming. One way to mitigate these effects is by adding value to vegetables. However, no studies show the main attributes consumers value of vegetables produced in the megadrought zone. The study’s objective was to evaluate consumer preferences and identify segments based on the extrinsic attributes of vegetables grown in areas depressed by drought. We surveyed 946 vegetable buyers from the Antofagasta, Valparaiso, and Maule regions. Through the conjoint analysis technique, we identified that the main attributes preferred by consumers were presentation (45.3%) and type of vegetables (21.8%), followed by labeling (15.9%), producers (10.3%), and origin (6.7%). The cluster analysis revealed the existence of three segments. The largest segment is motivated by the way vegetables are presented (49.7%), followed by a second segment that values multi-attributes (31.9%) and a smaller segment that is interested in labeling (18.4%). These findings can help position these products in the market and raise awareness of family farming and the economic and production problems that they currently face.

Food Supply Chain Safety Research Trends From 1997 to 2020: A Bibliometric Analysis

Background

The COVID-19 pandemic has exposed the fragility of the global food supply chain, strengthened consumers' awareness of the traceability system throughout the supply chain, and gradually changed consumers' consumption concepts and consumption patterns. Therefore, the aim of this study was to analyse the relevant literature on food safety in the food supply chain, examine its current status, hot spots, and development trends, and provide some suggestions for academics and relevant government departments in food supply chain safety research.

Methods

We collected the literature on the food safety research of the food supply chain from the Scopus database, used BibExcel to count the subject categories, published journals, geographical distributions, research institutions, authors, and keywords in the literature, and used Pajek software to analyse the keywords in the literature, perform co-occurrence analysis, draw related knowledge maps, and perform cluster analysis on primary keywords. Finally, to study the development trend, we used CorTexT software to illustrate the theme evolution path map in this research field.

Results

The keyword visualization network revealed the following key research topics: (1) food safety at the consumer end of the food supply chain, (2) food safety management in the food supply chain, (3) risk management of food safety in the food safety chain, and (4) food safety at the production end of the food supply chain.

Conclusions

After comprehensive discussion and analysis, we concluded that food supply chain management may be a hot topic in the future, especially in traceability management combined with the blockchain. It is necessary to explore in-depth how the blockchain can affect the food supply chain to provide a theoretical basis for managing the latter.

Consumer Trust in Food and the Food System: A Critical Review

Increased focus towards food safety and quality is reshaping food purchasing decisions around the world. Although some food attributes are visible, many of the attributes that consumers seek and are willing to pay a price premium for are not. Consequently, consumers rely on trusted cues and information to help them verify the food quality and credence attributes they seek. In this study, we synthesise the findings from previous research to generate a framework illustrating the key trust influencing factors that are beyond visual and brand-related cues. Our framework identifies that consumer trust in food and the food system is established through the assurances related to individual food products and the actors of the food system. Specifically, product assurance builds consumer trust through food packaging labels communicating food attribute claims, certifications, country or region of origin, and food traceability information. In addition, producers, processors, and retailers provide consumers with food safety and quality assurances, while government agencies, third-party institutions, advocacy groups, and the mass media may modify how labelling information and food operators are perceived by consumers. We hope our framework will guide future research efforts to test these trust factors in various consumer and market settings.

Consumer trust in the dairy value chain in China: The role of trustworthiness, the melamine scandal, and the media

This study provides a deep insight into Chinese consumer trust in the Chinese dairy value chain, as a lack of trust due to the 2008 melamine scandal has been widely recognized as a barrier to the development of the domestic dairy industry in China. Based on face-to-face interviews with 954 Chinese consumers in Beijing, Shanghai, and Shijiazhuang, this study measured consumer trust in farmers, manufacturers, retailers, the government, and third parties. Consumer trust was studied by measuring the effect of beliefs on the trustworthiness of actors (i.e., competence, benevolence, integrity, credibility, and openness), and current experiences regarding the melamine scandal and the media. The results showed that the level of trust in dairy chain actors varied. The government and third parties were relatively highly trusted, whereas retailers were considered less trustworthy. The importance of consumer beliefs about trustworthiness are different among actors. Consumer belief of competence determines trust in farmers and manufacturers. For retailers, the government, and third parties, respectively, benevolence, credibility, and openness are the most important factors. Trust in dairy chain actors is still strongly negatively affected by current experiences regarding the melamine scandal, even though it occurred more than 10 years ago. Using social media to directly provide more information and establish continuous daily communication with consumers could help manufacturers and third parties to strengthen consumer trust.

Food Safety Gaps between Consumers' Expectations and Perceptions: Development and Verification of a Gap-Assessment Tool

In recent decades, food safety has become a major concern due to frequent food safety incidents in many countries. This may lead to increased health risks associated with low quality food consumption, thereby reducing consumer trust in food safety. A better understanding of consumer perceptions of food safety can improve indicators that do not meet consumer expectations. We propose a food safety gap model with four gap-construct based on consumer expectations and perceptions. The model was empirically tested through a survey of 25 items, and then assessed for gaps through the importance–performance analysis (IPA). From a sample of 697 Taiwanese consumers, we found a huge gap between consumer expectations and perceptions related to food safety. More importantly, the results of the IPA indicate that most items must be immediately improved, which is vital in order to mitigate the risk of food safety.

Assessment of the Efficiency of Nitrogen Slow-Release Fertilizers in Integrated Production of Carrot Depending on Fertilization Strategy

Optimization of plant nutrition is a very important part of primary production quality systems. Crop fertilization is the most important agrotechnical measure because it determines the amount and quality of the yield. Moreover, excess fertilization intensifies the eutrophication processes and the greenhouse effect. The study aimed to assess the suitability of slow-release fertilizers in cultivation of carrot subspecies Daucus carota L. ssp. sativus in the integrated production system. The objective was realized on the basis of a strict field experiment set up on a clay loam soil with low nutrient content. The dose of fertilizer was the experimental factor. The fertilizers were applied during the formation of the ridges. Traditional fertilizers (ammonium phosphate, potassium salt, ammonium nitrate, and a multi-component fertilizer Polifoska 6), as well as a multi-component fertilizer with slow release of nutrients, NPK Mg (18-12-24-4), were used. In individual variants of the experiment, different fertilization strategies were applied: integrated production fertilization, traditional fertilization, and fertilization based on the use of slow-release fertilizers. The control treatment comprised of unfertilized plants. The efficiency of nitrogen fertilization was evaluated based on agronomic efficiency, partial factor productivity, physiological efficiency, and removal efficiency. Fertilization strategy significantly impacted the quantity of obtained yield. In the control sample, prior to mineral fertilization, the crop yield was 33.53 Mg·ha−1. The largest yield was 82.30 Mg·ha−1.The largest yields were obtained from plants fertilized with a combination of slow-release fertilizers, with nitrogen introduced in the form of ammonium phosphate, and through conventional fertilization. The highest productivity and environmental efficiency were obtained in treatments with fertilization according to the principles of integrated production and with slow-release fertilizers. In terms of environmental efficiency, the best results were obtained through nitrogen fertilization using 400 kg of slow-release fertilizers. The use of slow-release fertilizers in carrot cultivation can significantly improve the efficiency of fertilization, both in terms of production and environmental protection.
