Conservação pós-colheita de manga ‘Tommy atkins’ submetida a revestimento comestível e armazenada sob refrigeração.

Abstract

The use of edible biofilms is an option to increase the amount of marketing of fruit and reduce post-harvest losses. This study aimed to evaluate the postharvest mango 'Tommy Atkins' produced under organic and conventional systems by treatment with edible biofilms under ambient and chilled in two stages of maturation. The experiments were conducted in a completely randomized, factorial arranged in 4 x 5, with 3 repetitions of two fruits / plot, the first factor corresponds to the packaging treatments (0% control, PVC, 1% of cassava starch and 3% cassava starch: the second factor corresponds to the storage periods (0, 5, 10, 15 and 20 days) and (0, 3, 6, 9 and 12) for refrigerated and ambient temperature. storage was installed using selected fruits according to ripening stages (I - fruits of time, physiological maturity and II - fruit maturing commercial). application of Biofilm Cassava starch (BFM) was based on production systems (organic and conventional), which were covered with biofilm suspension of cassava starch at concentrations of 0% (control), 1% and 3% with PVC coating and as a means of comparison between edible. were evaluated physical, physical-chemical and subjective evaluations of appearance and sensory analysis. for weight loss, it was found that the cassava starch 3% was effective until 20 days of storage under the 12th C and 9 days at 24 oC. Fruits under the organic system showed were firm and glossy during all periods of storage, independent of treatments and temperatures used. temperature cooling was effective to increase the shelf life of fruits during post-harvest 20 days, independent of treatment and maturation stages evaluated.
