Processing method of black ginseng

Abstract

The invention provides a processing method of black ginseng. The processing method comprises the following steps: cleaning fresh ginseng, and removing moisture on the outer surface; then performing drying until the water content is 60%-80%; then putting the dried ginseng into a sealed tank body, starting to heat, controlling the temperature to be 55-65 DEG C, and performing reacting for 20-24 hours under the temperature condition; and performing heating to 80-90 DEG C, and performing reacting for 360-480 hours at the temperature to obtain a dark brown product, namely the black ginseng. The method is environment-friendly, simple and safe; in the processing process, bacterial growth can be inhibited, mildewing is avoided, and the carbonization phenomenon caused by high-temperature drying isavoided; the conversion rate of the protoginsenoside converted active saponin is greatly improved, and the conversion rate of the protoginsenoside converted active saponin reaches about 90%; the processed black ginseng has relatively high rare saponin and is free of harmful substance residues; and the content of the rare saponin component in the backginseng is higher than that of the prototype ginsenoside converted rare saponin component in the black ginseng processed by the traditional process.

Description

technical field [0001] The invention belongs to the technical field of ginseng processing, and in particular relates to a processing method of black ginseng. Background technique [0002] Black ginseng is the steamed dry root and rhizome of the cultivated product of Araliaceae ginseng. As a precious traditional nourishing traditional Chinese medicine, it has the functions of nourishing vital energy, recovering pulse and strengthening the spleen, nourishing the spleen and lung, promoting body fluid, and calming the nerves. Ginsenoside is the main active ingredient of black ginseng, including prototype ginsenoside and rare ginsenoside, which has various pharmacological effects such as anti-tumor, anti-aging, improving immunity and anti-arrhythmia. Prototype ginsenosides are ginsenosides extracted directly from Araliaceae plants (such as: ginseng, American ginseng, Panax notoginseng, etc.), including: Ra, Rb1, Rb2, Rb3, Rc, Rd, Re, Rf, Rg1, etc.; rare Ginsenoside is the conve...

Problems solved by technology

However, in the traditional black ginseng processing technology, the steam over 100°C is generally used to steam the ginseng, and the hot air over 100°C is used to dry the ginseng. Although this method can shorten the steaming time and drying time, it reduces the During the natural aging of ginseng, the active ingredients that black ginseng should have will be greatly reduced, and due to repeated hot air drying, the fine ginseng will be incompletely carbonized, forming harmful ingredients to the human body, more or less containing benzene Carcinogens such as pyrene

In the traditional black cucumber processing technology, low-temperature drying method is also adopted, which has the disadvantages of high cost and poor economy; or natural drying method, but it is difficult to avoid mold and bacterial reproduction in the process of natural drying; The method can avoid mildew, but it also has the disadvantage of short natural curing time

In addition, in the traditional black cucumber processing technology, there is also a microbial fermentation method, but the rare saponins obtained by this method are single

At the same time, in the existing traditional black cucumber processing technology, the conversion rate of prototype ginsenosides into rare saponins is extremely low
