Zenex Organic Gamma Oryzanol Powder – Rice Bran Extract Powder Pack of 100 Gram

Oryzanol is a mixture of ferulic acid esters mainly composed of triterpenoids (alkenes), which is a binding lipid between ferulic acid and plant sterols. It can be extracted from cereal oils such as rice bran oil and germ oil. The content of oryzanol in the rice bran layer is 0.3-0.5%. During the heating and pressing process of rice bran, coumarin is dissolved in the oil. Generally, the coumarin content in bran oil is about 2% to 3%. Its content varies slightly with the climate conditions of rice cultivation, rice varieties, and the process conditions for extracting oil from rice bran. Rice bran from cold regions has a higher content of vitamins than that from tropical regions; High temperature pressing and solvent extraction result in a higher content of oryzanol in crude oil compared to low-temperature pressing. Among many plant oils, such as corn germ oil, wheat germ oil, barley bran oil, rapeseed oil, etc., bran oil has the highest content of oryzanol, so most oryzanol is extracted from bran oil.
