Conservação pós-colheita de carambola sob refrigeração com recobrimento de biofilme de gelatina e PVC Postharvest conservation Star fruit refrigerated with biofilm coating gelatin and PVC

摘要: The objective of this study was to evaluate the Star fruit post-harvest preservation with coating gelatin and PVC. For this, starfruit cultivar 'sweet Giant' were harvested at physiological maturity, transported Postharvest Laboratory Federal Rural University Semi-Arid being selected as maturation, sanitized, dried separated into three groups for implementation coatings: fruits coanting individually a film solution 10% 1% glycerol plasticizer, covered four flexible polyvinyl chloride (PVC) 15μm per tray control (without coating). stored 10 ± 1 ° C 85-90% RH, valued five-day intervals 20 days mass loss, peel color, flesh firmness, soluble solids, titratable acidity, pH ascorbic acid. experimental design completely randomized in factorial 3 x 5, replications fruits. PVC more efficient minimizing loss during cold storage. While biofilm provided maintenance green color longer period time. An increase acid content decrease firmness storage
