With the aim of disclosing the antecedents and dynamics of food loss generation in the upstream stages of the fruit and vegetable sector, this paper presents the results of a series of semi-structured interviews with 10 Producers’ Organisations (POs) in Germany and Italy. The content of the interviews is analysed by applying a qualitative content analysis approach, thus disclosing the most relevant issues affecting food loss generation at the interface between POs and buyers (industry and retailers). Several similarities emerge as we compare the answers provided by Italian and German POs, especially concerning the role of retailers’ cosmetic specification on products in the generation of losses. Instead, the structure of contracts regulating commercial transactions between POs, industry, and retailers show noticeable differences, apparently resulting in a greater capacity to plan the demand of products from the beginning of the season in the Italian context. Despite these differences, this study confirms the key role of POs in increasing farmers’ bargaining power against the buyers, both in Germany and Italy. Further research is needed to compare circumstances in other European countries and to analyse why the similarities and differences identified occur.

An increasing number of individuals are eating out due to work and study commitments. This trend directly influences people’s food choices, especially those who frequently rely on snacks and pre-packaged foods. Consuming these foods can lead to long-term health consequences. Adding functional foods to vending machines could lead to healthier choices. Our aim is to evaluate the acceptability and willingness to pay (WTP) of workers and students for a snack pack of novel functional biscuits (FBs) made with high amylose contents. We found that the experimental flour used is effective in preventing various non-communicable diseases; two phases of analysis were carried out on 209 participants. The participants blindly tested the products and only after the sensory evaluation were they informed about the biscuits’ health contents. Firstly, the blind investigation highlighted the acceptability of the FBs compared to the conventional biscuits. Secondly, the finite mixture model on WTP revealed that some consumers are interested in the health benefits associated with high-amylose test blends and others are focused on hedonistic taste. The design of a communication strategy and industry approach should aim to assist consumers in comprehending the health benefits and sensory aspects of novel functional foods available on the market.

The different bargaining power of actors is a long-standing problem in the fruit and vegetable supply chain, where buyers (e.g., retailers, industry, and wholesalers) have more power than agricultural producers and are, therefore, able to engage in commercial practices that may be perceived as unfavorable or even unfair by the weaker part. This study explores how producers perceive the quality of commercial relations. The methods include a focus group discussion with sales managers of producer organizations and a survey of agricultural producers in Italy. We measure their willingness to change buyer and their stated overall satisfaction with the commercial relation by analyzing ninety-eight commercial relations and five dimensions of quality in the relationship. We identify four clusters of relationships characterized by different quality levels. The satisfaction and willingness to change buyers significantly differ across the clusters; economically favorable commercial relations are associated with a low willingness to change buyers, even when the producer is not satisfied with the overall quality of the relationship. The highest levels of satisfaction and the lower willingness to change buyers are reached for commercial relations that are not only economically favorable but also include positive relational aspects such as trust and mutual commitment.
