Embodiment 1

[0034] The extraction and purification process of the garlic polysaccharide of the present embodiment comprises the following steps:

[0035] (1) Degreasing: crush the dried garlic, sieve it, add the solvent for 1 hour each time, recover the solvent, and air-dry the residue;

[0036] (2) Ultrasonic treatment: Soak the filter residue obtained in step (1) in 30 times the weight of distilled water, and ultrasonically treat it with a power of 300W for 15 minutes to obtain a solid-liquid mixture;

[0037] (3) Enzyme treatment: add compound enzyme, then hydrolyze at 55°C for 50 minutes, then heat up to 90°C to inactivate the enzyme, filter with suction, collect the filtrate, concentrate to obtain a concentrated extract;

[0038] (4) Cooking: use boiler steam to heat, pass the steam directly through the concentrated extract, and distill until there is no garlic smell in the concentrated extract to obtain a cooking mixture;

Abstract

The invention discloses an extraction purification process of garlic polysaccharide. The process comprises the following steps: (1) degreasing; (2) ultrasonic treating; (3) enzyme treating; (4) stewing; (5) garlic polysaccharide extracting solution obtaining; (6) alcohol precipitating; (7) ion exchanging; and (8) drying. By adopting the specific complex enzyme and assisting by the ultrasonic assistant enzymolysis, the extraction rate is obviously improved in comparison with the ordinary thermal extraction method; moreover, the level-by-level ion exchange is performed on the garlic polysaccharide extracting solution, the purity of the garlic polysaccharide can be effectively improved, so that the high extraction purity can be guaranteed when the high extraction rate is guaranteed.

Description

technical field [0001] The invention relates to the technical field of garlic processing, in particular to a process for extracting and purifying garlic polysaccharides. Background technique [0002] Garlic is also called garlic, garlic head, garlic, gourd, single garlic, single head garlic, which is the general designation of garlic plants. Semi-annual herbaceous plant, Liliaceae Allium, used as medicine with bulbs. Harvest in spring and summer, tie up, hang in a ventilated place, and dry in the shade for later use. The agricultural proverb says "Garlic can't be planted for nine (months), but nine long and one head can be produced." When the leaves are withered in June, dig them out, remove the silt, and ventilate to dry or bake until the skin is dry. [0003] Garlic is oblate or short conical, with off-white or light brown membranous scales on the outside, with scale leaves removed, and 6-10 garlic cloves inside, growing in whorls around flower stems, stem bases are disk...
