Study of storage of fruit pulp of ginja Eugênia uniflora l. and their influences on levels of ascorbic acid and anthocyanins

Abstract

The sour cherry (Eugenia uniflora L. - Myrtacea) is a species endemic to the northern region of Rio de Janeiro and phenolic substances with antioxidant action presents, hypoglycaemic action and antireumatics are also used in stomach disorders and as antihypertensive. The Brazil it is the place where the best plant develops, reaching up to eight meters high. The aim of this work was to evaluate the best way of storage of apricot pulp in order to find better conditions for maintaining the content of Ascorbic acid and anthocyanins. The fruits were collected in the municipality of Salvaterra, Marajó Archipelago, Pará in the early hours of the morning, being collected manually from the trees. Then were sanitized to 10 ppm and evaluated their physicochemical parameters and studied as to its storage. For storing fruit and apricot pulp were studied for 60 days at intervals of 0.10, 20, 30 and 60 days under refrigeration temperature (± 8 °C) and below freezing (± -18 °C). The fruit and pulps stored for each time were submitted analyses of pH, titulavel acidity, humidity, ashes, soluble solids, total anthocyanins and Ascorbic acid. In relation to the physical and chemical parameters studied showed that refrigerated if had a greater variation in the results when compared to freezing for both the fruit and the apricot pulp. It was concluded that the best way of storing the fruit and apricot pulp was under freezing, where it was possible to verify that there was no significant losses of Ascorbic acid and anthocyanins.
