The invention relates to the field of
American ginseng processing, and discloses a method for
processing black
ginseng by taking fresh
American ginseng as a
raw material. The method comprises the following steps that 1, the fresh
American ginseng is washed to be clean, and then
skin moisture is drained; 2, the American
ginseng is placed in a steamer and heated to be 98-100 DEG C; 3, the temperature of the steamer is kept at 98-100 DEG C, and
steaming is conduced for 56-60 h; 4, a steam source is
cut off, and when the temperature in the steamer is lowered to 50-60 DEG C, the steamer is opened;5, the steamed American
ginseng is cooled and then put in a
drying room of 50-55 DEG C to be dried until the
moisture content is smaller than or equal to 12%, the dried American ginseng is taken out,and a finished product is obtained. By adopting the
processing technology, the content of ginseng rare saponins such as the ginseng
monomer saponin Rg3 and the ginseng
monomer saponin Rg5 in the American ginseng can be increased to the maximum extent, various original ginseng
monomer saponins of the
raw material fresh American ginseng are converted into ginseng rare monomer saponins to the maximumextent, and the rare glycosides can be kept not continue to hydrolyze. The effective ingredients ginseng
saponin Rg3 and ginseng saponin Rg5 of the American ginseng black ginseng are greatly increased compared with those of the traditional process, the technology is stable, the processing efficiency is high, and the effect is significant.
