Embodiment 1

[0035] Mix 80kg of garlic dregs (waste dregs for producing garlic essential oil) with 800L of pure water to obtain a garlic dregs feed liquid, add 20% NaOH solution at 47°C to adjust the pH of the garlic dregs feed liquid to 8.0; use the garlic dregs feed liquid The total weight of the garlic protein is 100%, and 3% by weight of compound protease is added to the garlic residue feed solution for enzymolysis for 6 hours to obtain the garlic residue feed liquid after enzymolysis; wherein AS1.398 is neutral in the composite protease Protease (1×10 5 U / g), 2709 alkaline protease (2×10 5 U / g) and papain (6×10 5 The weight ratio of U / g) is 1:0.16:0.08. Add 3M HCl solution to the enzymatically hydrolyzed garlic residue feed solution to adjust the pH to 6.0 and heat up to 75°C to extinguish the enzyme for 30 minutes to obtain the garlic residue enzymatic hydrolyzate, centrifuge the garlic residue enzymatic hydrolyzate, and separate to obtain the first A solid product and a first liq...

Embodiment 2

[0041] Mix 200kg of garlic residue (the waste residue of garlic essential oil) with 3000L of pure water to obtain a garlic residue feed liquid, add 20% NaOH solution at 52°C to adjust the pH of the garlic residue feed liquid to 8.5; use the garlic residue feed liquid The total weight of the garlic protein is 100%, and 1% by weight of compound protease is added to the garlic residue feed solution for enzymolysis for 4 hours to obtain the enzymolyzed garlic residue feed liquid; wherein the AS1.398 neutral in the composite protease Protease (1×10 5 U / g), 2709 alkaline protease (2×10 5 U / g) and papain (6×10 5 The weight ratio of U / g) is 1:2:1.5. Add HCl solution with a concentration of 3M to the enzymatically hydrolyzed garlic residue feed liquid to adjust the pH to 7.0 and heat up to 85°C to inactivate the enzyme for 20 minutes to obtain the garlic residue enzymatic hydrolyzate, centrifuge the garlic residue enzymatic hydrolyzate, and separate to obtain the first A solid produ...

Embodiment 3

[0047] Mix 80kg of garlic dregs (waste dregs for producing garlic essential oil) with 800L of pure water to obtain a garlic dregs feed liquid, add 20% NaOH solution at 47°C to adjust the pH of the garlic dregs feed liquid to 8.0; use the garlic dregs feed liquid The total weight of garlic protein is 100%, and 3% by weight of compound protease is added to the garlic dregs feed solution for enzymolysis for 6 hours to obtain the enzymolyzed garlic dregs feed solution; wherein AS1.398 neutrality in the composite protease Protease (1×10 5 U / g), 2709 alkaline protease (2×10 5 U / g) and papain (6×10 5 The weight ratio of U / g) is 1:0.16:2. Add 3M HCl solution to the enzymatically hydrolyzed garlic residue feed solution to adjust the pH to 6.0 and heat up to 75°C to extinguish the enzyme for 30 minutes to obtain the garlic residue enzymatic hydrolyzate, centrifuge the garlic residue enzymatic hydrolyzate, and separate to obtain the first A solid product and a first liquid product.

Abstract

The invention discloses a method for integrated extraction of multiple biologically active components in garlic residues, comprising the following steps: S1. Uniformly mixing garlic residues with pure water to obtain garlic residue feed liquid, and adjusting the garlic residue feed at 47-55°C The pH of the solution is 8.0 to 8.5, adding a compound protease for enzymolysis, and then inactivating the enzymatic treatment to obtain the garlic residue enzymatic hydrolysis product, and separating the solid and liquid to obtain the first solid product and the first liquid product; S2. Adding a flocculant to the first liquid product and Separating the second liquid product, the second liquid product is separated by an organic membrane to obtain a permeate and a retentate, and the retentate is dried to obtain garlic polysaccharide; S3. The permeate is decolorized to obtain a refined liquid, and the refined liquid is concentrated and dried to obtain garlic Oligopeptide; S4. The first solid product is dried and pulverized to obtain odorless garlic powder. The invention adopts an integrated extraction process, and the garlic polysaccharide, garlic oligopeptide and odorless garlic powder in the garlic residue can be extracted in one feeding, the process is simple, economical and environment-friendly, and the garlic residue is fully utilized.

Description

technical field [0001] The invention relates to the field of biochemical integrated extraction, and more specifically relates to a method for integrated extraction of various bioactive components in garlic residues. Background technique [0002] Garlic is a traditional edible plant in my country, rich in various nutrients. In addition, modern medical research shows that garlic also has a variety of pharmacological effects, such as antibacterial, bactericidal, antiviral, prevent lead poisoning, regulate blood lipids, anticoagulant, prevent arteriosclerosis Cirrhosis and cerebral infarction, protect the liver, prevent and treat hepatitis, inhibit tumors, lower blood sugar, improve the body's tolerance to glucose, etc. Because of its extremely high medical and edible value, it is widely used in industries such as medicine, food, cosmetics and health care products. [0003] At present, there are few reports on the integrated extraction technology of garlic, and most of the garli...
