Embodiment 1

[0021] A method for continuously extracting alliin, garlic polysaccharide and odorless garlic powder using fresh garlic as raw material, the steps are as follows:

[0022] (a) Put 100g of garlic cloves into a microwave oven to heat for 1min, cool down, put it into a tissue grinder, add 150mL of pure water (1.5 times), turn on the machine, mash the garlic into a homogenate, pour the homogenate into a beaker, and Stir and extract in a water bath at 55°C for 30 minutes, centrifuge to separate the liquid phase and the solid phase, dry the solid phase and pulverize to obtain 9.7 g of odorless garlic powder. The yield was 9.7%.

[0023] (b) Add 4.5mL (3%) of HACC solution to the liquid phase under rapid stirring, continue to stir for 3 minutes, let stand for 5 minutes, and centrifuge to obtain the clear liquid, which passes through 100g of H+ type 001×7 strong acidic cation exchange resin at a flow rate of 20mL / min, when the garlic polysaccharide is checked, the effluent is collec...

Embodiment 2

[0026] A method for continuously extracting alliin, garlic polysaccharide and odorless garlic powder using fresh garlic as raw material, the steps are as follows:

[0027] (a) Put 1000g of garlic cloves in a microwave oven and heat for 2min, cool, add 2000mL of pure water, coarsely pulverize, grind through a colloid mill, heat the slurry to 65°C, stir and extract for 40min, centrifuge, separate solid and liquid, and dry in solid phase Finally pulverize to get 101g odorless garlic powder. The yield was 10.1%.

[0028] (b) Add 115mL (5%) of HACC solution to the liquid phase under rapid stirring, continue to stir for 5 minutes, let it stand for 10 minutes, centrifuge, the slag can be used as feed, and the clear liquid is 2300mL, passed through 800gH+ type 001×7 strong acid cation exchange resin , the flow rate is 120mL / min (1 / 7BV), check the outflow of garlic polysaccharide and collect it immediately. After the feed liquid is fed, wash the feed liquid between the resins with pur...

Embodiment 3

[0031] A method for continuously extracting alliin, garlic polysaccharide and odorless garlic powder using fresh garlic as raw material, the steps are as follows:

[0032](a) Put 100kg of garlic cloves into a tunnel-type microwave oven, passivate allinase, cool down, add 300kg of pure water after coarse crushing, grind through colloid, put the slurry into a sandwich pot, heat to 75°C and stir for extraction After 70 minutes, centrifuge for solid-liquid separation, put the solid phase in a canvas bag and press dry, and then air-dry to obtain 13.02kg of odorless garlic powder. The yield was 13.02%.

[0033] (b) Add 21kg (6%) of HACC solution to the liquid phase under rapid stirring, continue to stir for 5 minutes and then let it stand for 30 minutes. For feed. The clear liquid passes through 70kg800gH+ type 201×7 strongly acidic cation exchange resin with a flow rate of 7L / min (1 / 10BV). Check that the garlic polysaccharide flows out and collect it immediately. Stop collecting...

Abstract

The invention discloses a method for continuously extracting alliin, garlic polysaccharide and odorless garlic powder by taking fresh garlic as a raw material. The method is characterized by comprising the following steps: a, heating and passivating garlic cloves in a microwave to obtain allinase, adding purified water, smashing into homogenate, heating, stirring, extracting and performing residue-liquid separation in sequence, and drying and crushing the residues to obtain the odorless garlic powder; b, treating a liquid phase by an HACC (Hydroxypropyltrimethyl Ammonium Chloride Chitosan) and a CTS-I type natural clarifying agent and then separating, adsorbing the alliin with 001*7 strong acid cation exchange resin, wherein effluent is the garlic polysaccharide, and performing evaporation, concentration and spray drying to obtain garlic polysaccharide powder; c, flushing the resin adsorbed with the alliin by using purified water to be clean, and then eluting with an ammonia-water solution, and performing deamination and concentration under reduced pressure, ethanol recrystallization and vacuum drying on eluant to obtain an alliin finished product. The method disclosed by the invention has the advantages that the cost ratio of garlic as the raw material in the product is greatly reduced, the market competitiveness of the product is improved, and the productivity is improved; no other pollutants are discharged, so the environment is protected.

Description

technical field [0001] The invention relates to the technical field of preparation methods of alliin, garlic polysaccharide and odorless garlic powder, in particular to a method for continuously extracting alliin, garlic polysaccharide and odorless garlic powder from fresh garlic. Background technique [0002] Garlic (Allium satirum) is the bulb of the Allium plant in the Liliaceae family. Because it is rich in bioactive components and nutrients, it has important functions of disease prevention, treatment and health care. It has always been regarded as a good product for both medicine and food. It is recommended by the World Health Organization (WHO) as 6 kinds of anti-tumor health food that should be eaten every day. one. Garlic has the function of enriching selenium in the soil, and selenium-enriched garlic has stronger anti-cancer and anti-cancer functions. Selenium is hailed as "the king of anti-cancer" by WHO. The international anti-cancer field believes that "seleni...
