Enriquecimento protéico da algaroba (prosopis juliflora) utilizando saccharomyces cerevisiae

Abstract

The present study was aimed to develop the protein enrichment process of mesquite using Saccharomyces cerevisiae by optimization of techniques generated or adapted to the condition of semi arid region, for the production of food sources rich in protein, vitamin, minerals and energy. The product obtained aims the animal feed, contributing to reduce food shortages in dry season of year. The experiments were conducted on PVC trays measuring 10 x 17,5 cm and height of 4,3 cm. We used 47, 94 and 141 g of raw material, distributed in the reactor, presented different thicknesses of the substrate. In conducting the tests were inoculated the same cell concentration and different pH and yeast extract as comparative parameters experimentally. It was made an experimental design 33, using three variables (mass of mesquite, pH and concentration of yeast extract) to optimize the parameters. It was adopted like response to crude protein content dry.The results for the 96 hours were statistically analyzed by the software Design Expert 7.1.5.The best results for protein enrichment of mesquite were to the process time of 96 hours. The higher protein enrichment of Mesquite was obtained with 96 hours of fermentation when used 47g of raw material, pH 7.0, and 0.3% yeast extract.
