Processamento de tomates (Lycopersicom escullentun Mill), cv. Débora cultivados de forma tradicional e orgânica, para obtenção de extratos

Abstract

This work aimed at to verify the chemical characteristics, physics, physiochemical and sensorial of extracts of obtained tomatoes of the cv. Débora, of traditional and organic plantings, planted in the City of Paty of the Second lieutenant, inside the State of Rio de Janeiro. Analyses of Brix were made, apparent viscosity, humidity, color, pH, total acidity, vitamin C, fibers, lycopene, b-carotene, life-of-shelf and they are also registered in this research the sensorial evaluation of the elaborated products, where they were appraised the color, the aroma and the flavor, through sensorial analyses done by individuals that pronounce to be consuming of tomato extract. The found results, for Extract of Traditional Tomato, Brix = 11,71; apparent viscosity = 2,67; humidity = 86,81; color: L = 36,59, a = 18,40, b = 13,04; pH = 4,44; total acidity = 12,56; ascorbic acid = 11,50; fibers = 0,29; lycopene = 4460 and b-carotene = 990, and for Extract of Organic Tomato Brix = 12,52; apparent viscosity = 2,62; humidity = 86,60; color: L = 37,80, a = 19,90, b = 15,39; pH = 4,32; total acidity = 19,48; ascorbic acid = 12,27; fibers = 0,29; lycopene = 4012 and b- carotene = 976, they showed that the respective extracts presented very close characteristics, being the very low variation among them. The sensorial evaluations, accomplished through affectivity test, they demonstrated a larger attraction of the fitting room for the extract of traditional tomato, but the difference among the two extracts, traditional and organic it was low. Through research accomplished the fitting room close to, it was verified interests for the consumption of organic products due to the fact of guaranteeing a better life quality, because in that case, they are being consumed foods of cultural treatments that you/they provide benefits to the health. On the other hand, they come across the financial subject, that today it is a great disrupt of the acquisition of organic products, besides the difficulty of finding that type of foods.
