Mixed drinks prepared with extracts of rice with passion fruit and papaya

Abstract

This study aimed at developing drinks prepared with extracts of rice, sugar and flavored with papaya and passion fruit pulp, and to evaluate the physical-chemical, chemical, sensory and microbiological characteristics. Cost of formulations, acceptability, yeast and mold counts and coliforms counting at 35 °C and 45 °C and Salmonella sp detection were investigated, and the additional features as chemical composition, sugars, dietary fiber, total titratable acidity, soluble solids and antioxidant potential. All of the drinks may be considered as functional foods owing to their total dietary fiber contents. However, the extract prepared with parboiled brown rice showed the highest contents of total dietary fiber (2.37g.100 g-1) and of soluble one (1.20 g.100 g-1). The passion fruit and papaya pulps drink turned out to be nutritionally richer in proteins and lipids, by adding the brown rice and brown parboiled rice. All of the drinks were accepted by the interviewed persons, being the purchase intention > 90 %, and their microbiological standards were in compliance with the Brazilian legislation. Broken rice, brown rice and brown parboiled rice may be used as ingredients in the papaya and passion fruit pulps-based beverages formulations.
