Problems solved by technology

[0003] However, benzoic acid exists widely in nature in the form of free acid, ester or its derivatives. In addition, ginseng growers use preservatives in order to prevent ginseng (garden ginseng) from being corrupted during growth, storage, processing, and sales. The amount of preservative residues in related products greatly exceeds the international standard, which greatly restricts the application and export of ginseng related products in my country, causing huge economic losses to the country every year

Embodiment 1

[0035] The preparation method of ginseng extract to reduce preservatives:

[0036]Receive raw ginseng (raw and sun-dried ginseng) 500kg. Take tap water with 18 times the amount of raw material (raw sun-dried ginseng), adjust the pH value to 10-12 with sodium carbonate, and mix well. Put the raw material (raw and sun-dried ginseng) into the prepared alkaline solution, and soak all the ginseng in the alkaline solution, rinse with a liquid circulation pump, and fully wash for 10-15 minutes. Drain the alkaline solution from the washed ginseng, wash the ginseng with tap water until the pH value of the washing solution reaches 7-8, add an appropriate amount of tap water to the washed ginseng to make it moist, cut into thick slices, and set aside. Put the sliced ​​ginseng into the extraction tank, add water to decoct twice, add 15 times the amount of ginseng in tap water for 2 hours, add 12 times the amount of ginseng in tap water for 1.5 hours, and filter the decoction , combined ...

Embodiment 2

[0038] The preparation method of ginseng stem and leaf extract reducing preservatives:

[0039] Get 500kg of raw ginseng stems and leaves (dried ginseng stems and leaves), take tap water 25 times the amount of raw materials (dried ginseng stems and leaves), adjust the pH value to 10-12 with sodium carbonate, and mix well. Put the raw materials (ginseng stems and leaves) into the prepared alkaline solution, and soak all the ginseng stems and leaves in the alkali solution, rinse with a liquid circulation pump, and fully wash for 10-15 minutes. Drain the alkaline solution from the washed ginseng stems and leaves, and wash the ginseng stems and leaves with tap water until the pH value of the washing solution reaches 7-8. Put the processed ginseng stems and leaves into the extraction tank, add water to decoct twice, add 18 times the amount of ginseng stems and leaves in tap water for 2 hours, and add 15 times the amount of ginseng stems and leaves in tap water for 1.5 Hours, filte...

Embodiment 3

[0041] The preparation method of ginseng fruit extract reducing preservatives:

[0042] Receive 500kg of fresh ginseng juice, add 3-5% calcium hypochlorite, keep stirring, and mix thoroughly for 20-30 minutes. Adjust the pH value of the processed raw materials to 9-10 with sodium carbonate, mix well, and let stand for 10 minutes. Add hot water at 80-90°C to 18 times the amount of raw materials to dilute, the diluted solution is 80-90°C, separate the diluted solution from solid to liquid, discard the separated solid, add sulfurous acid to the separated liquid Mix iron (0.1g / kg) and settle for 6 hours. Pass the settled supernatant through HPD-100 macroporous adsorption resin column (resin consumption is 500kg), DM130 macroporous adsorption resin column (resin consumption is 250kg) (the flow rate of the upper column is controlled at 2BV / h), Elute with water until colorless, then elute with 65% ethanol, collect the 65% ethanol eluate, recover ethanol, and concentrate the filtrat...

Abstract

The invention discloses a method for reducing the antiseptic residue in the extract of ginseng, ginseng leaf, ginseng stem, and ginseng fruit. The technology is characterized by comprising the following steps: oxidizing ginseng pulp, subjecting the ginseng pulp to a fresh-keeping treatment, disinfecting, alkalizing, soaking in hot water, extracting, separating, condensing, diluting, separating, condensing, and drying; alkalizing the ginseng, ginseng leaf, and ginseng stem, washing, extracting, separating, condensing, diluting, separating, condensing, and drying. The antiseptic is alkalized and decomposed by sodium carbonate; the ferrous sulfate is taken as the flocculant to remove the color, metal ions, and salt-type antiseptics; macroporous absorption resin absorbs the effective component and does not absorb the antiseptic, thus the water-soluble antiseptic is separated; the anion / cation resin is used to separate and remove the salt-type antiseptics; the solution is evaporated and condensed for two times, during the process the antiseptics are evaporated with the water steam; and during the drying process, because benzoic acid can rapidly sublimate at 100 DEG C, the antiseptic (benzoic acid) is quickly sublimated. Through the provided method, people can obtain products with complete active components, the antiseptic residues in the products are extremely low, or the products even contain no antiseptic residue.

Description

technical field [0001] The invention belongs to the technical field of medicine and hygiene, and in particular relates to a method for reducing residual preservatives in ginseng, ginseng stems and leaves and ginseng fruit extracts. Background technique [0002] The traditional Chinese medicine ginseng is the dried root and rhizome of Araliaceae plant ginseng. Ginseng has a long history of medicinal use in my country. Because of its precious medicinal value, it has become a research hotspot for Chinese and foreign scholars. Up to now, more than 300 components have been isolated from the aboveground and underground plants of ginseng, including ginsenosides, the two major active components of ginseng. and ginseng polysaccharides. In addition, the effective chemical components of ginseng also include amino acids, proteins, sugars, vitamins and trace elements. Ginseng has a significant impact on the human body's material metabolism system, blood transport system, spleen, kidne...
