Résumé:
The characterization of the transformations that take place during the fruit development of the result makes possible to identify the period in which the results join the biggest number of characteristics that express the quality of the result for the marketing in natura or industrial. So the objective of this study quantified the changes in the physical characteristics, chemicalphysically and antioxidant activity of the juice and profit of oil and starch of the seed of the pomegranate hp.'Molar‘, during the development of the result. The experimental delineation was it completely casualizado, whose treatments were constituted by the age of the results (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 days after the antese), with four repetitions constituted by five results by piece totalizing 20 results for treatment. After the harvest the results were transported for the Laboratory of Analyses of Foods of the Federal University of Big Prairie (UFCG), Campus Of - PB, where the physical analyses were carried out, chemical-physically, antioxidant activities of the juice. The analysis of profit of oil and starch of the seeds was carried out by the Laboratory Institute Anteater, - PB. Along the
development alterations took place in the physical characteristics, chemical-physically, antioxidant activity and of profit of the oil and starch of the seed. Pomegranates hp. ‗Molar‗ they had a mass of 200 g, oblique format, what concerns variable volume of the result increase was noted up to 100 days of age. The results presented alteration in the coloration of the bark from 50 days being that to 90 days the results presented coloration orangey-yellow. In the juice there was evolution of the color for a rose reddened with reduction of the intensity with the advancement of the age. For the chemical analyses (AT) noted reduction of the acidity titulável from 80 days whereas in the same period there was increase in the tenor of SS, SS/AT, total and reducing sugars and vitamin C with the development of the result. What concerns the pigments, fenólicos, antocianinas and carotenoides, happened what with the
increase of the age of the results, the concentration of fenólicos reduces linearly, whereas the concentration of antocianinas took place an increase polinomial when the very concentration was reached to 90 days when a reddish coloration is showing up, at the same time the
carotenoides presented the least concentration to 90 days of age with value of 0,18 µL/100
mL-1. The treatment of 90 days was what pulp presented the biggest antioxidant capacity with
values of 3501,00 g.polpa.100 mL of DPPH and 10546,52 a Trolox/g for the methods DPPH and ABTS respectively, revealing high antioxidant activity of the results in this period. Profit of the oil and starch of the seed was altered significantly during the development of the result of the pomegranate. There was addition of 11,57 % in the profit of oil of the 60 for 100 days after the antese, in against departure a decrease took place in the starch profit having the least profit in the results gathered to 100 days (12,97 %). Before the obtained results it is noticed that the results gathered to 90 days joined the biggest number of quality characteristics, which boards made possible to identify the age in which the results are suitable to be gathered, in the conditions of cultivation of the Meadows of Sousa, PB.
