Rice bran is a byproduct commonly used for animal feeding; however its nutritional value and potential application in human diet have attracted market interest. Its preservation for safe use is still a challenge, so the objective of this study was to determine the quality of commercially available rice bran samples subjected to different heat treatments (extruding, parboiling, toasting, and microwave oven heating) in order to promote stabilization during storage under room temperature. Rice bran samples were collected from two industries, and each treatment was divided in three parts, each corresponding to three repetitions. All samples were evaluated for moisture content, total microorganisms, mold and yeast counting, hydrolytic rancidity, and lipase...

Provedor de dados: 38
Autores: Aguilar-García,Carlos; Cioccia,Anna María; Gavino,Victor; Gutiérrez,Marlén; Hevia,Patricio.
Dietary fiber requirements are met by only a small fraction of the population. There is need for supplemented foods to fill this gap. Rice bran (RB) is high in fiber and has antioxidant properties. The effects of rice bran fiber on several metabolic indicators and the antioxidant capacity of rice bran in rats was reported. Rats were divided into 4 dietary groups: Vitamin E-sufficient with (+VitE/RB+) or without (+VitE/RB-) rice bran; Vitamin E-deficient with (-VitE/RB+) or without (-VitE/RB-) rice bran. Food intake, growth and feed efficiency were similar in all groups but wet and dry fecal mass of the RB+ groups were 3 times higher than the RB- groups. Blood hemoglobin and liver iron were also similar among all groups. However, the liver VitE...

Rice bran as a substrate for proteolytic enzyme production
Provedor de dados: 52
Autores: Sumantha,Alagarsamy; Deepa,Paul; Sandhya,Chandran; Szakacs,George; Soccol,Carlos Ricardo; Pandey,Ashok.
Rice bran was used as the substrate for screening nine strains of Rhizopus sp. for neutral protease production by solid-state fermentation. The best producer, Rhizopus microsporus NRRL 3671, was used for optimizing the process parameters for enzyme production. Fermentation carried out with 44.44 % initial moisture content at a temperature of 30 C for 72 h was found to be the optimum for enzyme secretion by the fermenting organism. While most of the carbon supplements favored enzyme production, addition of casein resulted in a marginal increase in protease yield. Fermentation was then carried out under optimized conditions to obtain the crude extract of the enzyme, which was partially purified by precipitation and dialysis. A 3-fold increase in the enzyme...

Studies on production of single cell protein by Aspergillus niger in solid state fermentation of rice bran
Provedor de dados: 52
Autores: Anupama,; Ravindra,Pogaku.
An attempt was made to apply the solid state fermentation (SSF) for the production of single cell protein (SCP) using oil free rice bran waste as substrate. A local isolate of Aspergillus niger, was used as protein source for the studies. Total proteins were extracted to estimate the mycelial biomass from the moldy bran. Carbonate-bicarbonate extraction buffer and a pH 10 was found to be most efficient among the buffers used for the extraction of the proteins from the organism. The effect of supplementation by various sources of nitrogen and mineral solution on the final biomass yield was compared. The influence of C/N ratio on the protein yield was also studied. Sodium nitrate at C/N ratio of 1.387 was found to be an effective nitrogen-supplementing...

Autores: Todhanakasem,Tatsaporn; Narkmit,Tipong; Areerat,Kamonchanok; Thanonkeo,Pornthap.
Background The major challenges associated with the fermentation of lignocellulosic hydrolysates are the reduction in the operating cost and minimizing the complexity of the process. Zymomonas mobilis biofilm has been emerged to resolve these complexities. Biofilm has been reported to tolerate to the toxic inhibitors and easily manipulated toward the cell recycle through the cell immobilization. Results Z. mobilis ZM4 and TISTR 551 were able to develop biofilms on DEAE cellulose under the differences in the morphologies. Z. mobilis ZM4 developed homogeneous biofilm that brought DEAE fiber to be crosslinking, while Z. mobilis TISTR 551 developed heterogeneous biofilm in which crosslinking was not observed. Ethanol production under batch and repeated batch...
