Thirty-two expert stakeholder (e.g., consumer advice center, state parliament at regional level, European Network for Rural Development, university and research center, chamber of tourism, rural development association, and social cooperative enterprise) interviews were conducted to examine consumer attitudes, values and preferences in relation to short food supply chains. These stakeholders have expertise in policy, consumer behaviour, the tourism sector and regulation. The interviewees represented the views of consumers, producers, and other actors who work with or within short food supply in seven European countries (Belgium, Germany, Greece, Hungary, the Netherlands, Spain, and Switzerland). Consumers were generally perceived to be aware of the environmental impact of food production. In terms of preferences, consumers would like to shop for local food the way they shop at the supermarket: having variety of products, accessibility, and availability. The relative lack of convenience and high prices associated with short food supply chains products were seen as the major barriers to their purchase. Consumers were thought to buy the products because of health and environmental benefits, a desire to support their local community, and a preference for tradition. However, relatively few consumers purchase products regularly from SFSC. The main segments are people who believe in short food supply chains values, middle class families with young children and elderly people. More can be done to educate and engage consumers regarding these chains, and market research is needed to inform which strategy is likely to be most effective in specific contexts such as the regional level.

The effect of African Yam Bean (AYB) flour substitution on the nutritional, functional and pasting properties of yellow root cassava grits was investigated. Cassava grits were obtained by peeling, washing, cutting (5.5 cm thickness in cubes), soaking (72 h, 28±2 °C), dewatering, roasting (120 °C, 20 min), sieving and milling. Roasted AYB flour was obtained by cleaning, roasting (190 °C, 10 min), dehulling, milling and sieving (425 μm). Simple lattice design was used to generate different formulations, 100:0; 90:10; 80:20; 70:30; 60:40 and 0:100 of cassava grits and AYB flour, respectively. These were analyzed for chemical composition, amino acid profile, minerals, functional and pasting properties. Total ash, protein, β-carotene and hydrogen cyanide were in the ranges of 2.16-2.66%, 2.72-20.43%, 1.33 to 3.97 µg/g and 0.07-4.47 mg/kg, respectively. Total essential amino acids and total non-essential amino acids were in the ranges of 32.51-40.18% and 59.82-67.48%. Potassium, calcium, magnesium, iron, copper, zinc, manganese and sodium of the blends ranged from 338.00-646.75, 188.00-508.00, 358.00-532.50, 59.25-140.00, 0.12-0.19, 1.07-1.71, 7.25-38.25, 25.25-161.50 mg/100 g, respectively. Bulk density, water absorption capacity, swelling capacity and swelling index ranged from 0.67-0.81 g/ml, 151.05-503.29 g/ml, 1.67-5.68 g/g and 2.86-13.32%, respectively. The blends of yellow root cassava grits and African yam bean flour could provide nutritious food formulations and offer good potential for food security.

Bromelain is a proteolytic enzyme that can be found in all parts of pineapple plant varieties. Pineapple crown (PC) has higher bromelain activity than other pineapple wastes such as peels and leaves. This study isolated bromelain from one variety of PC, namely Honi, and determined the optimum drying temperature as well as concentration of ammonium sulphate to obtain the best bromelain characteristics such as protein content, unit activity and specific activity. Honi PC was dried at various drying temperatures (35, 40, 45, 50, and 55 °C), and then extracted and purified using ammonium sulphate in various concentrations (20, 40, 60, and 80%), in order, to get bromelain. Furthermore, the yield of isolated bromelain was calculated and the protein content, unit activity and specific activity of bromelain characterised. The highest yield of crude bromelain (CB) was achieved at 35 °C. However, the highest protein level, unit activity and specific activity of CB were achieved at 55 °C (p < 0.05). Purification of CB using concentrations of ammonium sulphate in the range 40 to 80% resulted in a higher protein level (p < 0.05). The highest unit activity and specific activity of bromelain were achieved at a 60% concentration of ammonium sulphate (p < 0.05). 55 °C and 60% were the optimum drying temperature and concentration of ammonium sulphate respectively to achieve the best characteristics (2.16% protein level, 1.61 U/mL unit activity and 0.75 U/mg specific activity) for bromelain isolated from Honi PC. Honi PC isolated bromelain was shown to inhibit the browning reaction on apple fruits. The agroindustry waste product, Honi PC, has potential as a future alternative bromelain source.

Short food supply chains (SFSCs) are today widely promoted due to the positive impact on social, economic and environmental sustainability. However, short chains face several specific challenges (e.g., meeting the requirements of consumers and ensuring optimal operations). The application of innovative solutions and digitalisation can support the actors of SFSCs to achieve these goals. Solutions and methods were collected based on the innovativeness and applicability of SFSCs. Systematic analysis of the needs of SFSCs for technological and non-technological innovations was carried out by partners of the SmartChain project. Based on the research, recommendations were made for the participating SFSCs regarding potential innovations. A significant proportion of the identified solutions have digital elements that were collectively assessed as a suitable solution in the case of the studied SFSCs. The current work provides an overview of the potential implementation of the collected innovative solutions having digital elements and addresses the primary needs and issues of SFSCs where the application is relevant. Highlighted areas of performance are marketing, communication, packaging and labelling, and logistics.

The purpose of the study was to identify the motivations and the barriers that stakeholders face regarding Short Food Supply Chains (SFSC). Two focus groups with stakeholders of the agricultural sector and SFSC were conducted in the Netherlands and Switzerland. A first fundamental topic addressed by participants was the one related to the definition of SFSC, which is far from consensual,"short" being often associated and sometimes confused with local, direct, small, fair, ecological, fresh, healthy, etc. However, a series of positive and negative factors influencing SFSC development, and the involvement of agri-food stakeholders were identified. On the one hand, the unique relationship built through direct contact between producers and consumers, the fair distribution of value added in the chain that producers can find in engaging in SFSC, the increasing number of SFSC initiatives, the farm resilience, and territorial strategies that are being developed seem to be the most positive aspects, that can explain the trends moving towards these types of distribution channel. On the other hand, many hindering factors were also identified, such as weak communication and marketing capacity of producers, and a lack of efficiency and cooperation between peers. The fierce competition of conventional distribution, using green washing, together with a profusion of labels, price issues, and unsuitable standards were mentioned as the main threats faced by SFSC actors.

Brazil has a great variety of fruits which are rich in bioactive compounds, such as the genipap fruit. Both the peel and the pulp of genipap have beneficial components for health, making the study of this fruit important for the proper use of its functionalities. The objective of this work was the extraction of bioactive compounds from the peel and pulp of genipap by different techniques. Extraction processes were carried out using different devices (orbital incubator shaker, ultrasonic bath, and ultrasonic probe) and at different temperatures (40, 60, 70, 80 and 90 °C). The best process for extracting phenolic compounds from the pulp of genipap fruit was with the ultrasonic probe at 40 °C, which indicated the efficiency of applying the sound waves directly to the sample. Regarding the peel, the best method for extracting phenolic compounds was using the orbital incubator shaker at 80°C.

In recent times, Short Food Supply Chains (SFSCs), i.e., supply chains in which the number of intermediaries between farmer and consumer are minimal or ideally nil, and local markets have flourished in Europe, both in rural and urban areas. SMARTCHAIN is a 3-year Horizon 2020 multi-actor project of 43 partners from 11 European countries, including key stakeholders from the short food supply chain domain – a kaleidoscope of ‘actors’ where science meets a wide range of non-technical disciplines and stakeholders across the agri-food value chain. Its central objective is to develop a portfolio of technological, organisational, social, and digital innovations, which will be validated in a Living Lab approach (18 pan-European use cases on short food supply chains) ensuring powerful co-creation and testing. SMARTCHAIN will develop 9 national Innovation Hubs and the SMARTCHAIN Innovation Platform, a digital portal for building a stakeholder community, and facilitating engagement, communication, and knowledge exchange across stakeholders. This special issue focuses on the most recent developments with respect to innovation in short food supply chains and publishes original research articles in this field.

This study aimed to identify the barriers and facilitators of consumers purchasing from short food supply chains (SFSC). Eight focus groups were conducted with consumers in the rural and urban areas of Germany, Spain, Hungary and Greece. Participants generally felt that increasing the convenience of purchasing SFSC products (in terms of a proximal location and being able to purchase a wide range of produce in one place) was a prerequisite for them to buy such products. Food quality in terms of taste, freshness and organic status were also taken into account in purchase decisions, and there appears to be a greater focus on health rather than the environmental implications of organic production, although the environmental aspects are also appreciated. Some participants also like the idea of supporting their local community through purchasing from local producers and/or retailers. It was believed that small-scale production and SFSC result in better quality food, but participants had less confidence in the hygiene and food safety standards of SFSC compared to longer chains. Participants thought that consumers would purchase local food if they could more easily access a variety of local food in one place, such as through supermarkets, cooperatives, farm shops and markets, or an online platform that aggregates producers.

Blended learning refers to the use of conventional face-to-face learning experiences in combination with online education resources and practices. An increase in enrolments and a more diverse student body has intensified the demand to develop first-year teaching and learning pedagogies. Food science and technology lecturers must facilitate constructive learning in order to develop student skills, including critical thinking, teamwork, and self-directed learning. The aim of this investigation was to evaluate student perceptions of collaborative and blended learning. Students were exposed to various technology-enhanced pedagogical tools and face-to-face teaching strategies such as online academic journal reflections, video screencasts, group assignments, food processing practicals, and group crossword puzzles. A mixed-method survey consisting of multiple-choice, a 5-point Likert scale, and open-ended qualitative questions was administered via Blackboard. A total of 133 students were registered for the module, and 72.1% (n = 96) completed the survey. In this study, respondents felt they were prepared to complete the online group assignments (82%), which illustrates that they could learn the course material through collaboration. Moreover, 87% of the students agreed that they could keep up with the coursework in the blended format. Students recommended that there should be more lecture designed video screencasts, and they should be offered more opportunities to do oral presentations in this module. The respondents positively received collaborative and blended learning. The findings of this study, in general, affirm the merits of incorporating blended and collaborative learning in food science and technology curricula.

The food system has become globalized and industrial. As a consequence, food travels long distances to reach consumers and its production is over-reliant on chemicals, leading to high levels of carbon emissions and soil degradation. Short food supply chains (SFSCs) have been advocated as more sustainable alternatives and have been explicitly mentioned by the Dutch government and the EU as a strategy towards achieving sustainability goals. While SFSCs are viable on a small scale, scaling and mainstreaming them has proven difficult due to low margins, high costs, and steep learning curves. Their economic underperformance is particularly glaring when compared to the highly cost-efficient - albeit energy and resource intensive - conventional commercial supply chains. In practice, SFSCs therefore remain isolated success stories, failing to contribute to systemic change in food systems. In efforts to enhance the performance of SFSCs, this paper introduces the GAIN transition model, a novel framework based on gamification which provides a holistic and actionable framework for SFSC actors to coalesce and strategize around a common vision. We illustrate the underlying principles of GAIN and its potential for institutionalizing SFSCs. We find that thus far, GAIN has helped to catalyze action and has proven a useful tool which provides a common language for actors to navigate this complex space. Future research and more dissemination are needed to conclude with more certainty on the quantitative impact of GAIN in terms of enabling and strengthening SFSCs.
