The benefit of rice bran to human health is already wellknown. It is a rich source of fiber, vitamin B1, tocoferol and γ-oryzanol. Unfortunately, freshly milled rice bran has a short shelf life because of its high triaclyglycerol content, which tends to decompose into free fatty acids (FFA). The last are responsible for off flavor development during rice bran storage. In this research, hot scre...

Two experiments were conducted to evaluate the feeding value of rancid rice bran in finishing pigs. In exp. 1, fresh (FRB), rancid (RRB), pelleted and extruded rice bran were used to determine stability and nutrient digestibility. The free fatty acid (FFA) values of FRB and RRB were 8.2 and 15.3%, respectively. Some of the FRB was pelleted (70°C) or extruded (110°C). In exp. 2, a total of 48 pi...

Cereal Chem. 80(6):689–692 Hydrolytic rancidity restricts the utilization of rice bran, reducing its potential value. In the present study, three groups of eight rice cultivars each displaying different levels of oil concentration (high, medium, and low) were cultivated in 1999 and 2000 under field conditions and evaluated for oil content, hydrolytic rancidity, and esterase activity in the bran...

The effect on intestinal carcinogenesis of feeding a 20% wheat bran dietary supplement, either during and/or after the stage of carcinogen administration with 1,2-dimethylhydrazine, was examined in 48 male Sprague-Dawley rats fed defined diets for 31 weeks. Nutrient intake and body weight gain were equivalent in all groups of animals. In the rats fed bran during carcinogen administration, tumor...

Dietary fibers may limit mineral bioavailability through ion-exchange processes. To critically test this hypothesis, it is necessary to know the extent of mineral binding under gastrointestinal conditions. This work describes the merits and limits of methods devised to determine the extent of ion binding by dietary fiber in vivo. Corn bran was employed as the dietary fiber source. Bran was fed ...

Citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. Objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. Giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...

the importance of dietary fiber in normal and therapeutic diets has been acknowledged by numerous authors in recent years. dietary fiber has different physiological effects on human health. the recommended daily intake of dietary fiber is about 30 g, but less than this is often consumed. wheat bran is an excellent source of dietary fiber and is used to fortify foods. the nutritional benefits of...

production of thermostable alkaline protease in tray bioreactor for solid state fermentation is a unique process which may lead to an economical approach for production of enzyme from agricultural waste or low cost substrate. in solid state fermentation using tray bioreactor, several agricultural residues such as rice bran, sugarcane bagasse, wheat bran, barely bran, corn meal and corn husk wer...

Agro-industrial wastes such as sugarcane bagasse, wheat bran, rice bran, corn cob and wheat straw are cheapest and abundantly available natural carbon sources. The present study was aimed to production of amylase and xylanase simultaneously using agro-industrial waste as the sole carbon source. Seven thermophilic strains of actinomycete were isolated from the mushroom compost. Among of these, s...
