The β- glucan oat • More than 95% of oat soluble dietary fiber are located in the "oat bran (Oat bran)", whereas "oat bran" processed oats off after the outermost shell part, within which contains the most abundant cereal β- glucan. β- glucan structure in oats is β (1 → 3), (1 → 4) bonds, oat bran is the most important, most health benefits of a water-soluble dietary fiber. β- glucan as a glucose polymer, that is, when we are making films oats, sources have tasted the taste of sticky gelatinous substance, but it is representative of the level of the nutritional value of oats index components. The key nutritional effects of oats is that "β- glucan", β- glucan present in plant fiber, bran cereals, bread yeast cell wall and the cell walls of certain bacteria, as a D-glucose in a special bond polymerization made of polysaccharides, depending on the structure can be divided into two categories: β (1 → 3), (1 → 6) bonds: The main source for the yeast, mushrooms category. β (1 → 3), (1 → 4) bond: the main source contains oats, barley and the like.
β- glucan soluble and efficacy will be different depending on the source and bonds vary, oat β- glucan in the gut becomes viscous gel, the intestine can absorb substances (such as gall bladder acid), and with the blood cholesterol tangled up. Because this type of dietary fiber gel formation can not be absorbed by the body to digest, will be directl y excreted, it can increase the bile acid and cholesterol metabolism, rid the body of cholesterol for quite helpful
Oat β- glucan in the intestine via the increases in viscosity to control blood sugar and insulin in the amount of change, because this can slow down the digestive tract of the viscous carbohydrate absorption rate, reduce the absorption rate of glucose, thereby reducing the response to insulin stimulation the reaction, help stabilize blood sugar levels.
Β- glucan oat dietary fiber contained in the gel formed by the intestine can not be digested and absorbed by the body, in addition to the intestinal absorption of harmful substances can be excreted, and also as a prebiotic substance for the growth of probiotic digestive tract, thereby helping to improve the intestinal flora, maintain intestinal health. After β- glucan soluble dietary fiber contained in oats to absorb a lot of water, it could produce satiety, so that eaters can eat less in a long time, indirectly contribute to weight control.
