Problems solved by technology

[0004] At present, the dietary fiber is extracted from sea asparagus by the alkaline method, or a combination of alkaline and enzymatic methods. However, the repeated soaking and frequent heat treatment of the alkaline method will reduce the water holding capacity and expansion capacity of the dietary fiber product. In addition, the alkaline liquid discharged will cause environmental pollution; the dietary fiber is extracted by enzymatic method, and the treatment time is long;

Abstract

The invention relates to extraction of dietary fiber, in particular to an extraction method of sea asparagus dietary fiber. The extraction method comprises the following steps of S1, cleaning sea asparagus, drying, smashing, sieving and degreasing; S2, quickly extracting and separating to obtain filter liquor and a filter residue; S3, adding low-fat milk powder and saccharose into the filter liquor, homogenizing and sterilizing to obtain a culture solution; S4, inoculating a mixed culture into the culture solution, and culturing to obtain a fermentation agent; S5, adjusting pH of the filter liquor, then adding complex enzyme, and obtaining enzymatic hydrolysate through enzymolysis; S6, enzyme denaturing and cooling the enzymatic hydrolysate, inoculating the fermentation agent, culturing, and centrifugally separating to obtain filter liquor and a filter residue; S7, washing the filter residue with water, and drying to obtain insoluble dietary fiber; adding ethyl alcohol into the filter liquor, collecting sediments, and drying to obtain water-soluble dietary fiber; S8, mixing the water-soluble dietary fiber and the insoluble dietary fiber. According to the extraction method of the sea asparagus dietary fiber provided by the invention, the reaction condition is moderate, other impurities such as protein and starch can be effectively removed, the yield and the purity of the dietary fiber are improved, and the retention ability and the expansibility of the dietary fiber are improved.

Description

technical field [0001] The invention relates to a dietary fiber, in particular to a method for extracting sea asparagus dietary fiber. Background technique [0002] Sea asparagus (Salicornia) is a leafless succulent euhalophyte of the Chenopodiaceae Salicornia genus. It has high salinity tolerance. It is commonly known as sea caterpillar, Salicornia, salicornia or sea bean. Next to the beach. In recent years, with the continuous deepening of research on sea asparagus at home and abroad, polysaccharides, flavonoids, biological salts, chlorophyll and other active ingredients with medicinal and health value have been isolated from sea asparagus. Studies have shown that flavonoids have various physiological functions such as softening blood vessels, lowering blood sugar, lowering blood fat, anti-oxidation, scavenging free radicals in the body, anti-aging, anti-pathogenic microorganisms, anti-infection, anti-inflammation, anti-ulcer, anti-allergy, and promoting tissue regenerati...
