What Does Oat Beta Glucan Do For You?
What Does Oat Beta Glucan Do For You?
Oat Beta Glucan is a non-starch polysaccharide existing in the cell wall of oat endosperm and aleurone layer. It is a water-soluble dietary fiber. Its basic structure is a linear polysaccharide formed by D-glucose connected by β1-4 and β1-3 glycosidic bonds. The ratio of these two glycosidic bonds is approximately 7:3. Because of its viscosity, it hinders the digestion and absorption of starch, protein and other substances, and can proliferate beneficial bacteria in the digestive tract, so it can have some extremely beneficial physiological functions for the human body.
It is a macromolecular biopolysaccharide with multiple biological activities. It belongs to fiber polysaccharides and exists in many different foods, including yeast, oats, medicinal mushrooms (such as maitake and ganoderma), algae, etc. It has been widely used as a new resource food in our lives, dairy food and beverages, and has good health functions, such as lowering blood sugar, lowering blood lipids, and enhancing immunity.
Oats are a food that we particularly recommend in our healthy diet now. It is also the only cereal on the list of "Top Ten Healthy Foods in the World" selected by Time magazine in the United States. Oats are rich in oat glucan, which is very beneficial to the human body.
Extraction steps
① Treat some endogenous enzymes with ethanol solution and remove small molecular free sugars, proteins and some non-polar compounds;
② Treat starch with thermostable α-amylase, which can be performed simultaneously with the extraction of non-starch polysaccharides;
③ Add ammonium sulfate to preliminarily purify the extracted β-glucan or use enzymatic methods to remove and degrade arabinoxylan.
What Are The Benefits Of Oat Beta Glucan？
Lowers cholesterol
Famous for its cholesterol-lowering effect, the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) have shown that 3g of oat or barley beta-glucan per day is beneficial for lowering blood cholesterol levels and reducing the risk of coronary heart disease.
Lowers blood sugar
It can improve blood fluidity by lowering blood lipids, speeding up the transport speed and efficiency of sugar components during absorption and utilization. At the same time, it has a good repair effect on liver and kidney tissue lesions complicated by diabetes, and can effectively reduce the decomposition of liver glycogen, thereby reducing blood sugar.
Increase satiety
It can increase post-meal satiety, which may be due to the indigestible nature of beta-glucan in the gastrointestinal tract. In addition, studies have also shown that it plays an important role in reducing abdominal fat and obesity, mainly reflected in reducing weight, body mass index, body fat and waist-to-hip ratio.
Enhance immunity
It has an immunomodulatory effect. Long-term research has found that β-glucan and macrophages are a good pair. It can enhance the vitality of immune warriors-macrophages, quickly kill invading viruses, bacteria, fungi and other pathogenic microorganisms, and help you stay away from infectious diseases such as colds.
Improve the intestines
It is water-soluble. After absorbing water, it can moisturize the intestines, promote intestinal peristalsis, prevent constipation, and also shorten the time for waste to pass through the intestines. In addition, it cannot be absorbed by the human body and ferments in the large intestine to produce short-chain fatty acids such as propionic acid and butyric acid, inhibit putrefactive bacteria, promote probiotics, maintain the balance of intestinal flora, and prevent diarrhea or constipation.
What are the advantages for skin care?
Moisturizing effect
It has good film-forming properties, can reduce the evaporation of water on the skin surface, help water diffuse from the basal tissue to the stratum corneum, induce hydration of the stratum corneum, and play an emollient effect.
Anti-aging and sun protection
Effectively scavenges free radicals, fights UV damage, and has multiple effects of anti-aging and sun protection.
Repair skin barrier
It can promote the proliferation of Granhan's cells, has significant anti-inflammatory and anti-allergic activities, improves the recovery function of damaged skin, and accelerates skin wound healing. It is often used in wound care and repair products.
Transdermal penetration function
The molecular weight is relatively large, but it can enter the epidermis and dermis through the intercellular space, providing a new option for non-injectable natural treatment of skin wrinkles.
Application direction
Food
In the food industry, as a thickener, stabilizer and suspending agent, it is widely used in the production of yogurt, jam, baked goods and other products. It can improve the texture and taste of food, reduce the use of sugar and fat, and meet people's needs for healthy diet.
Health products
It can be used as a dietary supplement to help regulate blood sugar, lower cholesterol and enhance immunity. Studies have shown that it can reduce the absorption rate of fat and cholesterol in the small intestine, reduce plasma insulin concentration, and play a positive role in preventing cardiovascular diseases.
Cosmetics
As a moisturizing factor, it can increase the skin's ability to retain moisture and promote skin health. It can also balance the intestinal ecological stability and help maintain the health of the skin.
Medicine
It has multiple biological activities such as immunomodulation, antibacterial, antioxidant, anti-aging, and radiation protection. It has been widely used in functional foods, food additives and cosmetics. It can lower blood cholesterol, control blood sugar, improve intestinal health, and enhance immunity.
