Abstract

The invention discloses a production method of American ginseng polysaccharide peptide, which uses American ginseng stems, leaves and fibrous roots as raw materials, extracts with water, the ratio of solid to liquid is 1:10, extracts twice at 60°C for 2 hours, filters the combined filtrate, and vacuum Concentrate and filter to a ratio of 10:1, precipitate with 75% alcohol, centrifuge the supernatant to recover alcohol and extract saponin, then use 95% edible alcohol to elute the precipitate and recover alcohol. Dissolve the precipitate with water at a ratio of 1:10, add 1% flavor protease, hydrolyze for 4 hours at 55°C, pH 5.6, inactivate the enzyme, filter, concentrate in vacuum, and spray dry to make off-white polysaccharide peptide of American ginseng, which solves the problem of American ginseng extract Bitterness problem. American ginseng polysaccharide peptide can be taken directly or made into health drinks and capsules. American ginseng polysaccharide peptide can improve human immunity and lower blood sugar.

Description

Preparation and production method of American ginseng polysaccharide peptide

technical field

The invention relates to a preparation and production method of American ginseng polysaccharide peptide. The American ginseng polysaccharide peptide is prepared and produced by using American ginseng stems, leaves and roots through water extraction and alcohol precipitation, vacuum concentration, enzymolysis and spray drying.

Background technique

American ginseng (Panax quinquefoium L.) is a perennial medicinal plant of the Araliaceae ginseng genus. It is native to North America and later introduced to China. It is a precious nourishing medicine. American ginseng tastes bitter and slightly sweet, enters the heart, lung, and stomach meridians, and has the functions of invigorating vitality, nourishing blood and promoting body fluid, reducing blood pressure and relieving heat. American ginseng stems, leaves and roots contain ginsenosides, as well as proteins, polypeptides, amino acids, polysaccharides, fatty acids, trace elements, and volatile oils. The role of American ginseng saponins is to improve immunity and anti-fatigue, but it tastes bitter, while American ginseng polysaccharides and polypeptides are tasteless, not only can improve immunity, but also have the effect of lowering blood pressure. Using discarded American ginseng stems, leaves and American ginseng fibrous roots to extract and separate saponins and polysaccharide peptides, and then enzymatically hydrolyze them into polysaccharide peptides, so that polysaccharide peptides can improve immunity and lower blood sugar, solve the problem of bitter taste in the deep processing of American ginseng, and reduce the risk of American ginseng Effects of pesticide residues in stems and leaves.

Contents of the invention

The present invention uses American ginseng stems, leaves and fibrous roots as raw materials, extracts with water, the ratio of material to liquid is 1:10, at 60°C, the extraction time is 2h, extracts twice, filters and merges the filtrate, vacuum concentrates and filters to a concentration of 10:1, and eats 75% alcohol was precipitated, and the supernatant was centrifuged to recover alcohol and extract saponin, and then 95% edible alcohol was used to elute the precipitate to recover alcohol. Dissolve the precipitate with water at a ratio of 1:10, add 1% flavor protease, hydrolyze at 55°C, pH 5.6, for 4 hours, inactivate the enzyme, filter, concentrate in vacuo, and spray dry to make off-white polysaccharide peptide, which solves the smell of American ginseng extract Bitter problem, and can reduce pesticide residues in American ginseng stems and leaves. American ginseng polysaccharide peptides are made into health drinks and capsules, which can improve human immunity and reduce blood sugar.

Therefore, the use of this process to produce American ginseng polysaccharide peptides has off-white color, no bitter taste, good instant solubility, can be processed into health drinks or capsules, and can also be directly brewed with water, which is the first at home and abroad. American ginseng polysaccharide peptide has the health care effect of improving immunity and lowering blood sugar for human body.

Below in conjunction with embodiment the present invention is described in further detail.

Implementation example

① Raw materials: American ginseng stems, leaves, remaining fibrous roots of American ginseng workers.

② Polysaccharide protein extraction: American ginseng stems and leaves, add 10 times of water, extract at 60°C for 2 hours, extract twice, filter and combine the filtrate, concentrate in vacuum to 10:1, precipitate with ethanol concentration of 75%, and then wash with 95% ethanol Take off to obtain polysaccharide protein.

③ Polypeptide hydrolysis: add 10 times of water to polysaccharide protein, enzymatically hydrolyze for 4 hours at 55°C, pH 5.6, and inactivate the enzyme.

④Vacuum concentration: the hydrolyzate is concentrated in vacuum, and the mass number reaches more than 10%.

⑤ Spray drying: Spray dry the polysaccharide peptide, pulverize it, and sieve it into 100 mesh.

⑥Packaging: Pack the polysaccharide peptide with plastic.

⑦Usage: Take the polysaccharide peptide directly with boiling water, or make the polysaccharide peptide into a beverage and make capsules for consumption, which can improve human immunity and lower blood sugar.
