Problems solved by technology

Hot water extraction consumes a lot of energy, has low efficiency, and requires multiple extractions. Subsequent removal of water in the extraction solution consumes a lot of energy and takes a long time, which is not suitable for industrial production.
In the ethanol solution extraction method, the structure of peanut non-starch polysaccharides is easily destroyed in ethanol for a long time, the extraction rate is low, and the product activity is low
The acid and alkali solution extraction method is harsh, the peanut non-starch polysaccharide is easily denatured, and the production waste liquid is easy to pollute the environment

Abstract

The invention discloses a method for preparing peanut non-starch polysaccharides by utilizing hot-pressed peanut meal. The method comprises the following steps of: uniformly mixing peanut meal powder with distilled water; adjusting the pH value; adding compound plant hydrolytic enzyme ViscozymeL and carrying out microwave auxiliary enzymolysis to obtain enzymatic hydrolysate; adjusting the pH value of the enzymatic hydrolysate, adding the compound protease, carrying out microwave auxiliary enzymolysis, deactivating enzyme and centrifuging; adding the liquid supernatant to absolute ethyl alcohol which is 4 times the volume of liquid supernatant, stewing over the night in a refrigerator, centrifuging, washing the precipitates by alcohol and acetone, freezing and drying to obtain the peanut non-starch polysaccharides. The peanut non-starch polysaccharides which are prepared by the method disclosed by the invention have functional activities of preventing oxidization and lowering blood sugar, and are suitable for industrial production.

Description

technical field [0001] The invention relates to a method for preparing peanut non-starch polysaccharides by using hot-pressed peanut meal, and belongs to the field of food nutritional active substance processing. Background technique [0002] Peanut is an annual herbaceous plant of leguminous family, containing 25%-36% protein and 10%-23% carbohydrate. The light brown or dark brown small block or powdery by-products left after peanut oil extraction is called peanut meal, with an annual output of 4 million tons, which is a bulk protein and polysaccharide resource. Soluble non-starch polysaccharides can be obtained from the enzymatic hydrolyzate of peanut meal by ethanol precipitation. It is a kind of mixed polysaccharides including reducing sugars, neutral sugars, uronic acids or glycoproteins. Tumor, hypoglycemic, improve immunity and so on. Diabetes is a disorder of sugar, fat and protein metabolism. The cause is increased glucose production, but weakened utilization, res...
