Several important natural compounds, nutraceuticals–including vitamin E (tocotrienols, tocopherols) and oryzanols–have been shown to have important health benefits and are found in rice bran. This study was conducted to provide information regarding levels of these nutraceuticals within the rice kernel based on bran collected from successive milling but also to determine the level of nutraceuti...

Rice bran is an economical, under-utilized co-product of rough rice milling. The objective of this study was to produce rice-bran peptides and investigate for anti-cancer activity. Protein hydrolysates were prepared by treating heat stabilized defatted rice-bran with food grade Alcalase enzyme, followed by treatment with simulated gastric and intestinal juices to obtain resistant peptides. Resi...

Large amounts of seed storage proteins (SSPs) are produced in the maturing endosperm of rice seeds. Rice SSPs are synthesized as secretory proteins on the rough endoplasmic reticulum (ER), and are transported and deposited into protein complexes called protein bodies (PB-I and PB-II). Due to the high production of SSPs, unfolded SSPs may be generated during this process. However, it was previou...

Cereal Chem. 75(5):738-741 Milling data of four long-grain rice cultivars were analyzed to determine the uniformity in the slope of their curves for head rice yield (HRY) versus the corresponding degree of milling (DOM). The data set for each cultivar comprised samples that had been subjected to various drying air conditions and durations and milled over a range of moisture contents. All treatm...

in this study the effect of nano sized silica particles (nano-sio2) on the physical and mechanical properties of rice husk and old corrugated container (occ)-cement boards was investigated. modulus of rupture (mor), modulus of elasticity (moe), internal bonding strength (ib), density, water absorption and thickness swelling after 24 hours immersion in water and hardness were measured. results s...

Cereal Chem. 77(6):708–713 The effect of moisture content (MC) on the glass transition temperature (Tg) of individual brown rice kernels of Bengal, a medium-grain cultivar, and Cypress, a long-grain cultivar, was studied. Three methods were investigated for measuring Tg: differential scanning calorimetry (DSC), thermomechanical analysis (TMA), and dynamic mechanical analysis (DMA). Among these ...

Two long-grain rice cultivars/hybrids (‘Wells’ and ‘CL 161’) harvested from locations in Arkansas were used in this study. Rice samples were milled for 20, 30, 40, and 50 seconds. Milled whole-rice samples were cooked in excess water for 16, 18, 20, and 22 minutes and in a 2:1 water-to-rice ratio for 20 minutes (WR20). Cooked rice texture and solid leach were determined. Results indicated that ...

in this study the efficacy of intermittent and continuous drying processes on fissuring of hashemi and koohsar varieties was investigated. the fissuring of the kernels was assessed based on stress cracking index (sci). the experiments were carried out at drying and tempering temperatures of 30, 45 and 60 °c, drying durations of 20, 40 and 60 min, and constant tempering duration of 80 min. in co...
