in this research roasted and sonicated rice bran were added at different levels (0, 5, 10, and 15% w/w) to wheat flour for the production of semi-voluminous bread. dough's rheological properties as well as textural and sensory characteristics of bread were investigated. the results showed that water absorption (%), development time (min) and the degree of dough softening (fu) were increased but...

Extrusion is a multistep thermal process which has been utilized in a wide spectrum of food preparations. The effect of extrusion processing on the physicochemical, nutritional, and functional properties of Tarom cultivar rice bran was studied. However, the color of rice bran was improved by extrusion processing, but the protein content was reduced in the stabilized rice bran, which can be rela...

BACKGROUND Rice bran is a by-product of the rice-milling process, which remains largely underutilized; however, efficient processing treatments may improve its feeding value for chickens. This is of great economic and environmental importance, as this can lower the production costs, and offer an opportunity for valorization of a low-quality agricultural by-product, to a high-value feed source. ...

Increased consumption of whole grains has been associated with reduced risk of developing major chronic diseases. These health benefits have been attributed in part to their unique phytochemicals. Previous studies on black rice mainly focused on anthocyanins. Little is known about the phytochemical profiles and antioxidant activities of different black rice varieties. The objective of this stud...

Rice bran oil is unique among edible oil due to its rich source of commercially and nutritionally important phytoceuticals such as, oryzanol, lecithin, tocopherols, and tocotrinols. However, most of these phytoceuticals are removed from the rice bran oil as waste byproducts during the refining process. γ-oryzanol is one of such component having the potential to be used in nutraceutical, pharmac...

BACKGROUND: An inexpensive and readily available agroindustrial substrate such as rice bran can be used to produce cheap commercial enzymes by solid-state fermentation. This work investigates the production of food-grade proteases by solid-state fermentation using readily available Thai rice bran. RESULTS: A local strain of Aspergillus oryzae (Ozykat-1) was used to produce proteases. Rice bran ...

Rice bran, a by-product of rice milling industry is rich in micronutrients like oryzanols, tocopherols, tocotrienols, phytosterols and dietary fibers. The high nutritional profile of rice bran has not been utilized due to problems associated with lipase enzyme, which reduces the quality of rice bran and makes it unfit for human consumption. After the stabilization of lipase enzyme, it is possib...

BACKGROUND In the recent years, the health benefits of the pigmented rice varieties have reported due to the presence of bioactive compounds. In this study, the phytochemical constituents (total phenolic, flavonoid and anthocyanin content) and individual phenolics and flavonoids of the extracts of sixteen genotypes of pigmented rice bran were evaluated using spectrophotometric and ultra-high pe...

Cereal Chem. 77(5):551–555 Rice bran contains high amounts of beneficial antioxidants including tocopherols, tocotrienols, and oryzanols. Current rice milling technology produces rice bran from different layers of the kernel caryopsis. Under current practices, these layers are combined and then steam-extruded to form a stabilized rice bran pellet that is storage-safe prior to oil extraction. Ea...

Suitable substrates for laccase production by the thermotolerant basidiomycete Coriolus versicolor strain RC3 were screened using solid and liquid media. In liquid basal medium, 1%(w/v) rice bran as a carbon source was found to be the most efficient substrate for laccase production compared to 1%(w/v) glucose, wheat bran and rice straw meal. After 15 days cultivation at 37°C in shake flask cult...
