Problems solved by technology

Most of the existing reports are to ferment ginseng total saponins or monomeric common saponins. The raw materials fermented by these methods must be extracted and purified from ginseng or purchased separately, and the cost is relatively high; while direct fermentation with ginseng water extract, the current method Although the content of rare saponins is increased to a certain extent, the conversion efficiency is not high, and the content of rare saponins obtained is single

Embodiment 1

[0035] (1) Strain activation: Sterilize the prepared MRS medium by high pressure steam, cool it to about 60°C and invert it on a plate, inoculate the Lactobacillus plantarum subsp. 24 hours. Acetobacter pasteurianus solid medium composition: 1% yeast extract, 1% glucose, 2% agar, 2% ethanol, pH 6.0, the percentages are mass percentages, and the balance is water. Inoculate the Acetobacter pasteuriani preserved on the slant on the solid medium of Acetobacter acetobacter, and incubate it upside down at 30°C for 24 hours.

[0036] (2) Seed culture: Take 250mL Erlenmeyer flasks, fill each bottle with 50mL MRS medium, cool after sterilization, pick a single colony of Lactobacillus plantarum subsp. Let stand for 24 hours. Acetobacter liquid medium formula: yeast extract 1%, glucose 1%, KH 2 PO 4 0.25%, ethanol 2%, pH6.0, percentage is mass percentage, balance is water; 250ml shaking flask is filled with 50mL of culture medium, picks single colonies of Acetobacter pasteuriani in ...

Embodiment 2

[0046] (1) Strain activation: Sterilize the prepared MRS medium by high pressure steam, cool it to about 60°C and pour it into a plate, inoculate the Lactobacillus plantarum subsp. plantarum subsp. Inverted culture at 35°C for 24 hours. Acetobacter pasteurianus solid medium composition: 1% yeast extract, 1% glucose, 2% agar, 2% ethanol, pH 6.0, the percentages are mass percentages, and the balance is water. Inoculate the Acetobacter pasteuriani preserved on the slant on the solid medium of Acetobacter acetobacter, and incubate it upside down at 30°C for 24 hours.

Abstract

The invention belongs to the field of fermentation, and in particular relates to a method for increasing the content of rare saponins in water extracts of ginseng. The method comprises the following steps: using microwave ultrasonic co-extraction to prepare ginseng water extract, using the ginseng water extract as a fermentation substrate, and fermenting and transforming to produce four kinds of rare ginsenosides. By adjusting the compounding method of the starter and the conversion temperature, the content of characteristic rare saponins in the fermented liquid is greatly increased. The method has a simple process, and can increase the content of specific rare saponins through compound fermentation of strains under the condition that four kinds of rare saponins are simultaneously produced, and the conversion rate is high. It can be applied to ginseng deep-processing products with different needs.

Description

technical field [0001] The invention belongs to the field of fermentation, and in particular relates to a method for increasing the content of rare saponins in water extracts of ginseng. [0002] technical background [0003] Ginseng (Panax ginseng C.A.Mey) is the root of Araliaceae perennial plant ginseng. It is a traditional traditional Chinese medicine. Ginsenoside (ginsenoside GS) is the main material basis for the physiological activity of ginseng, and it is also the most effective medicinal ingredient in ginseng ingredients. Less rare ginsenosides (rare ginsenosides) have stronger biological activities and pharmacological effects, and have extremely high medicinal value and application prospects. For example, the rare ginsenoside Compound K (CK) has good effects on anti-tumor, anti-inflammation, anti-diabetes, anti-thrombosis, anti-aging and liver protection; Rg3 can induce tumor cell apoptosis, enhance the body's immunity, etc. effect. A variety of compound Chinese m...
