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 21Â 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

Quality Evaluation of the Ready-to-Eat Avocado cv. Hass
Consumer interest in avocado fruit has increased in the last decade in Europe. Nutritional and quality attributes affect the choice of these fruits, whose characteristics must also be maintained in the postharvest period. The preference regarding the feasibility of eating ripe fruits can assure and improve the success of the emerging marketing of avocados. The exposure of fruits to exogenous ethylene (C(2)H(4)) treatment can accelerate the process of fruit ripening. The aim of this work was at improving the existing knowledge about the quality traits of avocado cv. Hass fruits at the ready-to-eat stage. The most important qualitative traits (weight loss, dry matter content, hardness pulp, and external and internal fruit colour) were evaluated up to 96 hours, maintaining the fruit at two different temperatures, T1 (+8°C) and T2 (+17°C). A trained sensory panel was conducted at 96 hours to confirm the quality of avocado cv. Hass ripened with exogenous C(2)H(4)
