Abstract

The invention belongs to the field of oat bran deep-processing, and particularly relates to an oat bran active polysaccharide extraction and purification method. The method includes the steps that polysaccharide is extracted through preprocessing, degreasing and ultrasound-microwave synergistic extraction, and finally the yield, the purity, monosaccharide composition, the antioxidant activity andthe antilipidemia activity of the extracted oat bran active polysaccharide are analyzed. According to the oat bran active polysaccharide extraction and purification method, an oat bran active polysaccharide mixture is extracted by means of an ultrasound-microwave synergistic method, the polysaccharide with the antioxidant and antilipidemia regulating activity is obtained through dialysis, vacuum concentration and freeze-drying, the extraction method is simple, the operation cost is low, extraction duration is short, the yield and the purity of the obtained oat bran active polysaccharide are 8.45% and 93.2% respectively, and the oat bran active polysaccharide has good antioxidant and antilipidemia regulating activity.

Description

technical field

[0001] The invention belongs to the technical field of oat bran deep processing, and in particular relates to a method for extracting and purifying active polysaccharides from oat bran. Background technique

[0002] Oat bran is the outer tissue of oats obtained after cleaning oats or oatmeal after grinding and sieving. However, the structure of oats is soft, and the bran and endosperm cannot be completely separated, so oat bran contains more endosperm powder. Compared with other grain bran, oat bran is rich in water-soluble dietary fiber. Fiber is an important functional polysaccharide. But at present, oat bran has not been deeply developed for its health function except for a little use in bread, granules, etc., and its economic benefits are low. Therefore, extracting biologically active substances from oat bran is helpful for increasing the economic value of oat bran It is particularly important to improve the social benefits of agricultural and sideline ...
