Conservação e qualidade pós-colheita de tangerina ‘Clemenules’ em tempos de armazenamento e de comercialização

Abstract

Brazil is the largest producer of citrus fruits, tangerines and the second group of citrus produced more. Due to increased demand for these fruits for fresh consumption in the domestic market and for export, a major challenge is to look for fruit growing this fruit reaches the consumer with quality similar to that obtained in the field. Among the post-harvest practices, refrigerated storage is the most used technique for quality assurance of vegetables. This work aimed to evaluate the post-harvest quality of mandarin fruit ‘Clemenules’ at different times of storage and marketing simulation. The experiment was conducted in the months of May and June 2014, where mandarin fruit 'Clemenules' were stored in temperature of 8°C and RH of 90 to 95% for 7, 15 and 30 days. After each storage period, fruits were subjected to temperatures of 15°C and 90-95% RH for two and four days simulating the marketing. The weight loss (%), color, pH, vitamin C, total soluble solids (TSS), total acidity (TA), evaluations TSS / TTA and juice yield (%) were made at harvest and each storage period, followed by commercialization simulation. The experimental design was completely randomized with three replications of 10 fruits per treatment, 3 x 2 factorial (3 x 2 term storage periods commercialization simulation). After analysis of variance, the data were compared by Tukey test (p 0.05). After 15 days of storage increased the weight loss, the vitamin C content of the juice yield and decreased. The pH values increased after 30 days of storage, so with solids (TSS). Fruit quality will be decreased from 30 days of storage. We conclude that the mandarin fruit 'Clemenules' maintains its physical and chemical characteristics of quality up to 15 days of storage will be 8° C and 90-95% RH and marketed for up to four days will be 15°C.
