Oat bran and its nutritional composition

The relatively soft texture of the oat kernel results in the bran not being able to detach from the top of the endosperm during oat processing, leaving a small amount of endosperm still intact with the bran.

The yield is 30%-40%, and the total amount of dietary fiber in the bran is greater than 30%. As a by-product of oat processing, the composition of oat bran is rich in protein and water-soluble dietary fiber β-glucan, about 11.33%, although the composition varies depending on many factors.

Oat bran dietary fiber can be extracted from oat bran, due to the high nutritional value of oat bran dietary fiber makes the bran also play a good therapeutic role.

Functional properties of oat bran dietary fiber

1. Fermentation
Oat bran dietary fiber laxative, short-chain fatty acids, intestinal peristalsis metabolic process has a role in the production of short-chain fatty acids, in the gastrointestinal oat bran dietary fiber through the fermentation effect of the intestinal environment of the microbial acidity and alkalinity of a certain degree of change, which produces a large number of beneficial bacterial flora.

2.Water-holding and water-absorbing and swelling properties
Oat bran dietary fiber has some functional characteristics for water, its ability to hold water and absorb water swelling ability.

Bran has a very important role in pasta. By adding oat bran dietary fiber, the water absorbency of the pasta can be improved, which saves the time used for the dough to rise. Oat bran dietary fiber water-absorbing expansion can make people feel less hungry, can keep the stomach and intestines clean, the intestinal tract is extremely conducive to smooth, prompting peristalsis, so that dieters to reduce the appetite so as to achieve the purpose of weight loss, reduce the gastrointestinal tract infection and inflammation.

3. Reduce blood sugar
In 1985, Harold proved that adding oat bran dietary fiber in the diet can improve diabetes, and achieved considerable results. Oat bran dietary fiber on the human body’s second largest digestive gland in the enzyme has the role of promoting the activity of Zhao Naixin, etc. through a number of studies can be seen, the experimental staff through the consumption of wheat bran dietary fiber, the body of the blood indicators of some of the changes that occur in the body, such as blood glucose decreased efficiency of 89.8%, cholesterol and constipation of the treatment rate of 100%.

4. Adsorption of toxic substances
When consuming wheat bran dietary fiber, you need to pay attention to the dosage, to avoid improper intake, causing malabsorption of substances in the stomach and intestines and nutrient absorption disorders. Bran dietary fiber can prevent the damage in human organism by binding heavy metals in the body by binding heavy metals in the body.

Enforceable standards
