Value-added processing with respect to rice milling has traditionally treated the rice bran layer as a homogenous material that contains significant concentrations of high-value components of interest for pharmaceutical and nutraceutical applications. Investigators have shown that high-value components in the rice bran layer vary from differences in kernel-thickness, bran fraction, rice variety...

Gamma oryzanol (GO) is well known for its antioxidant activity and health-promoting benefits. The gamma oryzanol-loaded zein nanoparticles (GOZNs) were successfully prepared in our previous study. In the present work, acute oral toxicity of GOZNs was evaluated based on OECD guideline 420. fabricated by liquid-liquid dispersion lyophilized. samples displayed a mean diameter 311.20±3.01 nm high l...

Ferulic acid (FA) is widely used as an antioxidant, e.g., as a Ultraviolet (UV) protectant in cosmetics and in various medical applications. It has been produced by the hydrolysis of γ-oryzanol found in rice bran oil soapstock. In this study, the base-catalyzed, homogenous hydrolysis of γ-oryzanol was conducted using various ratios of potassium hydroxide (KOH) to γ-oryzanol, initial concentrati...

Brown rice (BR) or unmilled rice is the whole grain of rice, from which the germ and outer layers containing the bran have not been removed. Brown rice seeds are rich in more nutritional components, such as dietary fibers, vitamins B and E, gamma (γ)-oryzanol and γ-amino butyric acid (GABA) than the ordinary milled rice grains. GABA or 4-aminobutyrate is a well known non-protein-based amino aci...

The phase behavior of binary mixtures of γ-oryzanol and β-sitosterol and ternary mixtures of γ-oryzanol and β-sitosterol in sunflower oil was studied. Binary mixtures of γ-oryzanol and β-sitosterol show double-eutectic behavior. Complex phase behavior with two intermediate mixed solid phases was derived from differential scanning calorimetry (DSC) and small-angle X-ray scattering (SAXS) data, i...

OBJECTIVE S There is corroborating evidence to substantiate redox imbalance and oxidative stress in sepsis that finally leads to organ damage or even death. Gamma oryzanol (GO) is one of the major bioactive components in rice bran has been considered to function as an antioxidant. The present study was carried out to evaluate the antioxidant activity of gamma oryzanol in vitro and its efficacy ...
