Melão amarelo (CAC) minimamente processado submetido a diferentes cortes e concentrações de cloreto de cálcio armazenado em atmosfera modificada passiva

The aim of this work was to evaluate the quality of yellow melon inodorus Valenciano Amarelo (CAC) fresh cut submitted to two cut types and with application postharvest of calcium chloride. After preparation cubes and slices melon were immersed in solution with different calcium chloride (CaCl2) concentrations for two minutes, afterwards they were conditioned in trays of expanded polystyrene (EPS), covered by plastic film of low density polyethylene (PEBD), stored in cold camera to 5 degrees C +/- 1 and analyzed for 8 days. They were evaluated pH, firmness, tritable acidity (AT), soluble solids (SS) sugar reducer and ratio. The pH values varied from 5.27 to 5.68. The sugars reducers content and the ratio were superior in the slices compared to the cubes. The melon slices maintained larger firmness values compared to the cubes and in general there was reduction in the values of this parameter along the storage period for all treatments. Concentrations of 1.0 and 1.5% of CaCl2, result in larger values of firmness. The storage temperature and modified passive atmosphere they contributed to quality maintenance of MP melon. Concentrations of up to 1.0% of CaCl2 they could be recommended to maintain the melon quality MP melon yellow inodorus (CAC).
