Physico-chemical and chemical quality of acerola fruit clones coated with PVC film and conserved under refrigeration

Abstract

This work aimed to evaluate the physical, physicochemical and chemical changes in fruits of clones of acerola coated with PVC film and conserved under refrigeration. The clones BRS 235 (Apodi), BRS 236 (Cereja), BRS 237 (Roxinha), BRS 238 (Frutacor), II 47/1 and BRS 152 (Sertaneja) had been harvested in the stage of commercial maturation. The fruits had been washed in chlorinated water, packed in expanded polystyrene trays, covered with film PVC and stored (10ºC) during 12 days, with withdrawals of samples at the beginning of the experiment and to each three days. They had been evaluated: coloration, soluble solids, titratable acidity, soluble solids:titratable acidity relation, pH, soluble sugars, vitamin C, anthocyanins, weight lost, firmness and carotenoids. The experiment was carried through in experimental delineation completely randomized in factorial design (clones x time), with 3 repetitions (trays with 100g of fruits). Between the clones studied the II47/1 if it detached for the relative stability of the color, angle hue, and of anthocyanins, being more attractive for the consumer in the time of the purchase. However the clones Roxinha and Sertaneja had presented superior soluble solids:titratable acidity between the others in the end of the experiment, interesting characteristic for the flavor.
