Embodiment Construction
[0011] Grind the dry and clean garlic stalks into medium powder, add 5 times the amount of water and stir to make the impregnation evenly, impregnate for about 4 hours to ensure the impregnation, adjust the pH value to 4.0-5.0 with sulfuric acid, add 1-10% cellulase (the activity unit is about 2000U / g) and fully stirred, the constant temperature is in the range of 39°C (±1°C), enzymatic hydrolysis for 24h, stirring once every 2h. After enzymolysis, heat to inactivate the enzyme, and add to 100°C and continue to decoct twice, each time decocting for 1 hour, filter while hot, save the filtrate, beat the filter residue with a beater and combine it with the filtrate in a jacketed pot Further condense into a thick paste, dry in the range of 80-90°C to obtain 1 gram of dried concentrated extract equivalent to 10 grams of original dried garlic stalks, and grind the dried enzymatic extract into a very fine powder (150 mesh ), sieve and package the finished product.

Abstract
The invention relates to a novel extracting method for extracting active ingredients in cells by the following steps: selecting cellulose, hydrolyzing and degrading ingredients of cell walls and breaking the structures of the cell walls to enable the active ingredients to be exposed, dissolved, suspended or peptized in a solvent by utilizing the characteristics of high specificity of enzyme reaction according to the components of the cell walls of a garlic straw; and furthermore, the invention is beneficial to improving the extraction ratio of the active ingredients, and the fiber of the garlic straw is hydrolyzed to form glucose by utilizing an enzymatic hydrolysis method. The extracting method is realized by the following steps: crushing the garlic straw, carrying out enzymatic hydrolysis, decocting, filtering, concentrating, drying, crushing and obtaining a finished product. The method has the advantages that the application of the enzymatic hydrolysis method enables nutritive and active ingredients in the garlic straw to be extracted and improved and a large quantity of fibrin in the garlic straw and leaves to be hydrolyzed and converted into glucose, increases the content of carbohydrates in the product, further improves the effects of the product, lowers the production cost, avoids environment pollution, further embodies the advantage of comprehensively utilizing resources and better industrial application prospect in the aspect of improving the quality of the product and the like.
Description
technical field [0001] The invention relates to a method for extracting effective components of garlic stalks by hydrolyzing biological enzymes. Background technique [0002] After the garlic is harvested, the stalks and leaves are thrown away by garlic farmers, which not only pollutes the environment but also causes waste. Because both straw and leaves contain volatile allicin, rich in protein, sugar and cellulose, and also contain a small amount of nutrients such as phosphorus, potassium, calcium, magnesium and vitamin A, if applied to livestock and poultry feed, it can improve Meat-to-feed ratio, improve the quality and flavor of the feed, and have no toxic and side effects, no residue in the body, no drug resistance, can be used continuously, and can resist viruses, improve the meat quality of animals and other functions, and are suitable for livestock, poultry, cattle, sheep, pigs Rabbits, chickens, ducks, geese, and freshwater fish all have growth-promoting effects.
