Abstract

The invention provides a comprehensive utilization method of asparagus. The method includes the following steps that the asparagus is preprocessed; the preprocessed asparagus is crushed and pulped, and slurry is obtained; cellulose and pectinase are added into the slurry, enzymolysis reaction is conducted at 45 DEG C to 55 DEG C under the acidic condition, and a decomposition product is obtained; flavones in the decomposition product is adsorbed, and asparagus flavones and residual liquor are obtained; lactobacillus bulgaricus and streptococcus thermophilus are added to the residual liquor, fermentation is conducted at 35 DEG C to 45 DEG C, and fermentation liquor is obtained; the fermentation liquor is filtered, and trapped fluid and permeate liquid are obtained. According to the comprehensive utilization method of the asparagus, the asparagus is deeply developed, at least two target products of asparagus liquid beverage and asparagus flavones can be obtained, and the method has the advantages of being high in comprehensive benefit, various in product variety, free of damage, free of additive production and the like.

Description

Technical field [0001] The invention relates to the field of food processing, in particular to a comprehensive utilization method of asparagus. Background technique [0002] Asparagus is one of the top ten famous dishes in the world, also known as asparagus and asparagus (different from Haifacai-deep-sea vegetables, also known as asparagus). It enjoys the reputation of "King of Vegetables" in the international market. Asparagus is rich in a variety of amino acids, proteins, vitamins, bio-polysaccharides, flavonoids and phytosteroids. Its content is higher than that of ordinary fruits and vegetables, especially The asparagine in asparagus and trace elements such as selenium, molybdenum, chromium, manganese, etc., have the effects of regulating the body's metabolism and improving the body's immunity. It also has the effects of anti-tumor, anti-aging, lowering blood fat, anti-fatigue and protecting the liver. [0003] Fresh asparagus is not easy to preserve, and it is often processed...
