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
