Gel is the how the extracted oat β-glucan powder look like. It also contains a small amount of starch and protein. Because β-glucan is rich in oat endosperm cell wall, it is often extracted from oat bran.Generally, there are 3 steps extract β-glucan
① Treat part of endogenous enzymes with ethanol solution and remove small molecule like free sugars, proteins and some non-polar compounds;
②remove starch with thermostable α-amylase, carried out together with the extraction of non-starch polysaccharides if required ; ③Adding ammonium sulfate to initially purify the extracted β-glucan or using enzymatic methods to remove and degrade arabinoxylan.
1. In the past two decades, domestic and foreign scholars have proved through human clinical observations or animal experiments that oats can be used to prevent and treat cardiovascular and cerebrovascular diseases, diabetes, and obesity caused by hyperlipidemia.
2.In 1996, the US FDA believed that oats could reduce the incidence of coronary heart disease and allowed oat foods to be promoted without approval. β-glucan is generally considered to be the main functional component of oatmeal for lowering blood lipids, and its main function is to lower blood cholesterol levels.
In addition to β-glucan, oat extract also contains a lot of phenolic substances, including ferulic acid, caffeic acid, vanillic acid, erucic acid, anthraylamines, etc., which have antioxidant capacity in vivo and in vitro. It can scavenge free radicals and inhibit lipid peroxidation.
Exist in oat grains, it has good hygroscopicity, absorbs moisture in the air for the skin, and forms a film on the skin surface to lock moisture for the skin; promotes collagen synthesis, maintains skin elasticity, prevents wrinkles, and delays aging . It can be used for anti-aging, anti-wrinkle, sun protection, post-sun repair, and products for sensitive skin.
