Abstract

The umbu (Spondias tuberosa Arruda) is a fruit tree adapted to the Brazilian semiarid region and constitutes an important source of income for many families in Brazil. Due to this, sustainable methods of fruit postharvest conservation should be studied. The objective of this study was to analyze the influence of cassava starch-based biofilm coatings for the postharvest conservation of umbu. The experimental design was completely randomized in a 2x5 factorial arrangement with six replicates. The two treatments, 1% cassava starch coating and no coating, were evaluated during five periods (0, 3, 6, 9, and 12 d of storage). Fresh weight loss (WL), fruit firmness (FIR), pH, total soluble solids (TSS), total titratable acidity (TA), TSS/TA ratio, external color: luminosity (L*), hue angle (H*), and chromaticity (C*) were measured. The coating of fruits with cassava starch-based biofilm improved WL, pH, and TSS. The variables TA, TSS/TA ratio, and L* were not influenced by the use or absence of the cassava starch biofilm coating. The use of 1% cassava starch to coat the fruits ensures better postharvest quality of the umbu and extends its posthavest life.

使用木薯淀粉为基础的涂层延长海绵体(Spondias tuberosa Arruda)的采后寿命

乌布(Spondias tuberosa Arruda)是一种适应巴西半干旱地区的果树，是巴西许多家庭的重要收入来源。因此，应研究水果采后保存的可持续方法。本研究旨在分析木薯淀粉基生物膜涂层对芜菁采后保存的影响。试验设计完全随机化，采用2 × 5因子设计，共6个重复。在贮藏0、3、6、9、12 d期间，对1%木薯淀粉包衣和未包衣两种处理进行评价。测定新鲜失重(WL)、果实硬度(FIR)、pH、总可溶性固形物(TSS)、总可滴定酸度(TA)、TSS/TA比、外显光度(L*)、色相角(H*)和色度(C*)。木薯淀粉基生物膜包衣改善了果实的WL、pH和TSS。使用或不使用木薯淀粉生物膜包衣对变量TA、TSS/TA比和L*没有影响。使用1%木薯淀粉覆盖果实，确保更好的乌布采后质量，延长其采后寿命。
