Gamma-oryzanol from rice bran oil – A review
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...
متن کاملDetermination of gamma oryzanol in rice bran oil by HPLC with molecularly imprinted solid-phase extraction
A molecularly imprinting technique can be used for the separation of gamma oryzanol which gives high selectivity and affinity towards template molecules. This technique was successfully applied for the molecularly imprinted polymer (MIP) synthesis via photopolymerization method by using diethylaminoethyl methacrylate (DMAEMA) as a function monomer, gamma oryzanol as template, dodecanol as porog...
متن کاملFractionation of the rice bran layer and quantification of vitamin E, oryzanol, protein, and rice bran saccharide
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...
متن کاملComparative Analysis of γ-Oryzanol, β-Glucan, Total Phenolic Content and Antioxidant Activity in Fermented Rice Bran of Different Varieties
Rice bran, a by-product derived from processing rice, is a rich source of bioactive compounds. Recent studies have suggested that the fermentation can improve their biological activities. This study aimed to determined the level of γ-oryzanol, β-glucan and total phenol contents of fermented rice bran from 21 Korean varieties, as well as to evaluate their antioxidant activities. We also assessed...
متن کاملThe effect of single screw conveyor stabilization on free fatty acids, α-tocoferol, and γ- oryzanol content of rice bran
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...
