Processamento, caracterização físico-química e aceitabilidade de xaropes obtidos de frutos de cubiu (Solanun sessiliflorum Dunal) e camu camu (Myrciaria dubia McVaugh)

Abstract

The cubiu (Solanum sessiliflorum Dunal) and the camu camu (dubious Myrciaria McVaugh) they are fruits native fruit of the Amazonian, with great potential tecnólogico in function of the productivity, income in pulp and nutritional value. On the other hand, being added to the fan of desirable characteristics also stands out the loss of the fruit in natura for lack alternatives for industrialization, conservation, aggregation of value and means for the consumption, and, above all, the need of simple technologies. With objective of joining value, to diversify the industrial use, to obtain products with good consumption characteristics and to contribute for the reduction of the losses powder-crop, it was elaborated syrups of fruit in cubiu natura and camu camu. The coming ripe fruits of planting in the Experimental Station of Meadow of INPA went by the selection stages, wash, sanitização, cut (except camu camu), retreat of the seeds, fatiamento, cooking in syrups to the base of sugar (sucrose) and of sweetener (the base maltodextrina and artificial edulcorantes: cyclamate of sodium and sodic saccharin), despolpa, pasteurization, stuffing the hot, closing and cooling. In the concentrated syrups they were appraised the income and the physiochemical characteristics (acidity titulável, soluble and total solids, insoluble solids in alcohol, density, pH, total carotenóides, total and acid antocianinas ascorbic) and in the obtained refreshments of the concentrate sensorial analysis as for the characteristic profile (flavor, color, aroma and appearance) and the acceptability for scale structured hedônica of seven points. The cubiu syrups and camu camu the sucrose base presented tenors of soluble solids respectively 53 and 59 ºBrix above the patterns demanded by the legislation, and the one of cubiu with sweetener 15 ºBrix. The refreshments with dilution of 1:7 (concentrado:água) they received excellent notes for the sensorial attributes (color, flavor, aroma and appearance), acceptabilities of 98 % (cubiu sucrose), 100 % (cubiu sweetener) and 94 % (camu camu sucrose). The results indicate the cubiu fruits and camu camu as a matter excels appropriate for technological use in the syrup form.
