Fig. 1 is the equipment flowsheet that the extracting method of ginseng peptide provided by the invention is used.

Embodiment

Technical scheme for a better understanding of the present invention, describes embodiment provided by the invention below in detail.

The embodiment of the present invention provides a kind of extracting method of ginseng peptide, it is characterized in that, comprises step:

A, steaming and decocting under high pressure: steaming and decocting under high pressure: adopt temperature 120-128 ℃, pressure 0.12-0.16MPa, constant temperature and pressure boiling 0.5-1.5 hour, Radix Ginseng extractive solution enters jug used for heating up water, and ginseng residue discharges; Dry ginseng's matter is harder, and surface is lark, section yellowish white, and form layers ring grain brown color, there be point-like resin canal and the radial crack of yellowish brown in skin zone, and gas is special, mildly bitter flavor, sweet.The advantage of fritter shape boiling: the fritter shape ginseng of doing of take is raw material, and ginseng, without smashing, is beneficial to the separated of extracting solution and slag, and operation is simple, extraction yield is high, and is conducive to the raising of product clarity.

B, enzymolysis: extracting solution is arranged into hydrolytic decomposition pot by jug used for heating up water, after intensification sterilizing, be cooled to 50-56 ℃, add NaOH and adjust PH=7.0, add again 0.5% (in dry-matter, being: ginseng specific enzyme accounts for the weight percent of ginseng dry-matter) ginseng specific enzyme (comprising: restriction endonuclease, excision enzyme and food flavor enzyme form, wherein restriction endonuclease is containing 35%, excision enzyme is containing 35%, food flavor enzyme is containing 30%), enzymolysis 3-4 hour, in enzymolysis process, every 20-40 minute, stir 1-3 minute, enzymolysis is evenly carried out fully;

C, absorption: the floss that extracting solution produces after enzymolysis can affect the clarity of product, need adsorb through gac, therefore add the gac of 3-5% (in dry-matter) to adsorb after enzymolysis finishes, then add after NaOH adjusts PH=6.5 to heat up to go out enzyme sterilizing and be cooled to 70-76 ℃, standing 1.5-2.5 hour;
