Problems solved by technology

[0006] The dietary fiber content of the chewable tablet produced by the existing method is about 20%. This is because the existing oat dietary fiber preparation method, one is to directly use oat bran without extracting the dietary fiber, so the content cannot reach more than 30%.
In addition, even if the dietary fiber is extracted, the extraction rate is not high due to the difference in the extraction method, and the composition of the auxiliary materials is different. If it is to reach 30%, the taste of the chewable tablet will become worse, so it is generally around 20%.

Abstract

The invention discloses a high-content oat dietary fiber preparation and a preparation method. The preparation includes: (1) uniformly mixing oat bran powder and water after sieving and removing impurities, adjusting pH, gelatinizing, and adding α-amylase to liquefy , add glucosidase for saccharification, add papain for enzymolysis, boil to inactivate enzyme, centrifuge to obtain precipitation and enzymolysis solution; dry the precipitation to obtain crude fiber; (2) adjust pH of enzymolysis solution, concentrate, add absolute ethanol , centrifuged; the precipitate was dissolved in distilled water, ammonium sulfate was added, left to stand, precipitated, and centrifuged; (3) the precipitate was dissolved in distilled water, filtered under pressure, and the filter cake was freeze-dried, which was the crude product of β-glucan; 4) Mix the crude fiber and crude β-glucan to obtain oat dietary fiber, and then add acceptable auxiliary materials for health food to prepare a high-content oat dietary fiber preparation. The oat dietary fiber content in the preparation of the present invention is high. The invention improves the utilization rate of oat bran, turns waste into wealth, and increases the added value of products.

Description

technical field [0001] The invention relates to a high-content oat dietary fiber preparation and a preparation method, belonging to the field of health food production and preparation. Background technique [0002] China has a long history of oat planting, which was cultivated about 3,000 years ago. Oat bran is a by-product of oat processing. It contains less calories than oats, and the content of various nutrients per unit weight is several times higher than that of oats. But at present, most oat bran in our country is only used as feed, and the economic benefit is not high. Therefore, actively developing the deep processing and utilization of oat bran has great practical significance and good application prospects. [0003] Oat bran is rich in nutrients, the total dietary fiber content is as high as more than 30%, starch is about 30% and protein is about 20%. Among natural grains, only oats and barley contain water-soluble dietary fiber, especially oat water-soluble diet...
