Rice Bran (De-oiled)

Rice Bran De-Oiled is an ideal ingredient for Fisheries, Poultry and Cattle Feed. We offer different qualities for various uses. Though of low cost, it is rich in the valuable amino acids-methionine, cystine & lysine and phosphorus-avital and expensive mineral. Further, because of its low fibre content and adequete metabo- lisable energy, the deoiled rice bran is in great demand for use in fisheries / poultry as well as in cattle feed.

Rice bran is a primary by-product of the traditional rice processing industry. Once oil is extracted from rice bran, the left over residue is called de oiled rice bran (DOB). Its disposal presents economic and environmental problems. Microbial conversion of DOB into single cell protein (SCP) is an innovative practical approach for protein supplementation of a staple diet. The present research was undertaken to test the growth of industrially important fungi, Aspergillus oryzae MTCC 1846 on DOB through solid state fermentation (SSF) technology. Various process parameters effect such as moisture, pH of the substrate, inoculum size, temperature and nitrogen source for maximum protein enrichment were studied. The optimum conditions for the enrichment process were found to be moisture content 60%; temperature 280C; pH 6.0; inoculum’s concentration 109 spores/ g substrate and particle size of DOB, 0.3 mm. Among the various nitrogen source tested, ammonium sulfate (0.6% w/w) showed maximum protein enrichment (24.30%) followed by vegetable + fruit waste extract (23.50%) and legume root extract (23.10%).
