Effects of innovative packaging materials on apricot fruits (cv Tom Cot®)

Introduction. Innovation in the management of perishability/freshness is an essential theme of the future fruit sector, not only for commercial and distribution systems but also for production. Plastic films with modified atmospheres represent a postharvest technology that can be used to store stone fruits, such as apricots, that have a short shelf life when maintained in a normal atmosphere under cold conditions. The aim of our work was to evaluate the effect of several packaging materials on the postharvest quality of apricot fruits stored for 21 days by considering the most important qualitative traits. Materials and methods. Modified atmosphere technology with different packaging materials was used to store apricot fruits cv. Tom Cot® at (+1 ± 0.5) °C and 90–95% relative humidity (RH). Different passive modified atmosphere packaging (MAP) conditions were developed because of the interaction between fruit respiration and the different oxygen and carbon dioxide barriers of the films. The effects of MAP were evaluated on the postharvest quality of the fruits by monitoring the headspace gas composition, weight loss, fruit flesh firmness (FFF), total soluble solids content (TSS), titratable acidity (TA) and skin colour. Results and discussion. Changes in packaging headspace gas composition were observed for all films used, but only multilayer films and biodegradable film maintained the MAP conditions until the end of storage. Wrapped fruits lost less weight than fruits maintained under normal conditions; in particular, multilayer films maintained the highest FFF values after 21 days. The biodegradable film exhibited good performance in terms of maintaining the CO2 and O2 equilibrium inside the baskets by balancing the fruits’ respiration and the film’s permeability. Traditional plastic materials, such as multilayer films, and more sustainable films, such as the biodegradable film used in our study, can be successfully employed to store apricot fruits cv. Tom Cot® for up to 21 days in passive MAP conditions

Environmental and Social Sustainability in the Fresh Fruit and Vegetables Supply Chain: A Competitiveness’ Asset

The concern for products that meet the requirements of sustainability is a key factor that drives consumers and can be the engine of a successful economy in the food businesses. In the specific case of the fresh fruit and vegetables, more than ever, sustainability understood as a greater focus on the social and environmental performance of the product and of its supply chain, can be considered as a tool to counter the consumer\u27s disaffection. The communication of the product\u27s sustainability can indeed represent a tool to bring out the fruit and vegetable products from the anonymity, a strategy to will make it ‘remember\u27, relying not only on the traditional values recognized to the segment, but also on a set of the supply chain attributes that can differentiate it. However, how to get effectively to the consumer by using a multidimensional and complex concept as the product\u27s sustainability of the product, how to make the sustainability attribute a factor to be considered in the final purchasing choices, how to involve the different stakeholders in the building of a sustainable supply chain (regardless of its length) are still open discussion topics. After presenting the main sustainability certification and communication tools adopted till nowadays for the fresh fruit and vegetables supply chain, the chapter investigates the relative potentialities and criticisms in order to turn them into a real competitiveness’ asset

An interpretive framework for assessing and monitoring the sustainability of school gardens

School gardens are, increasingly, an integral part of projects aiming to promote nutritional education and environmental sustainability in many countries throughout the world. In the late 1950s, FAO (Food and Agriculture Organization) and UNICEF (United Nations Children's Fund) had already developed projects to improve the dietary intake and behavior through school and community gardens. However, notwithstanding decades of experience, real proof of how these programs contribute to improving sustainability has not been well-documented, and reported findings have mostly been anecdotal. Therefore, it is important to begin a process of collecting and monitoring data to quantify the results and possibly improve their efficiency. This study's primary goal is to propose an interpretive structure-the "Sustainable Agri-Food Evaluation Methodology-Garden" (SAEMETH-G), that is able to quantifiably guide the sustainability evaluation of various school garden organizational forms. As a case study, the methodology was applied to 15 school gardens located in three regions of Kenya, Africa. This application of SAEMETH-G as an assessment tool based on user-friendly indicators demonstrates that it is possible to carry out sustainability evaluations of school gardens through a participatory and interdisciplinary approach. Thus, the hypothesis that the original SAEMETH operative framework could be tested in gardens has also been confirmed. SAEMETH-G is a promising tool that has the potential to help us understand school gardens' sustainability better and to use that knowledge in their further development all over the world
