Ecology-simulated freshness-retaining method of ginseng and American ginseng

Abstract

The invention discloses an ecology-simulated freshness-retaining method of ginseng and American ginseng, which is characterized in comprising the steps of: adding 3% of saccharose and 0.1% of potassium benzoate into MS major element solution; soaking a cotton paper with the solution to be made into a nutrition paper; packing the rootlets and the fibrils of the O3-sterilized fresh ginseng or American ginseng with the nutrition paper; covering a PE freshness-retaining internal bag out of the package part of the nutrition paper; putting the packed ginseng or American ginseng into a PE freshness-retaining external bag; vacuating the external bag; aerating mixed gas of 2-3% of 02, 3-4% of CO2 and 95-93% of N2; and sealing the external freshness-retaining bag, and refrigerating under the environment of 0-2 DEG C. The method uses O3 sterilization to prevent the fresh ginseng from rotting and deteriorating, and the freshness-retaining bags simulate the ecological environment of the dormant state of the ginseng or the American ginseng to lead the fibrils not to be withered and yellow, and the color and luster, the freshness and the hardness of the whole ginseng not to be changed, therefore, the freshness-retaining time is more than 6 months. The method is simple in operation and is convenient in mass production.

Description

technical field [0001] The invention relates to a fresh-keeping method for ginseng or American ginseng, in particular to an eco-imitative fresh-keeping method for ginseng or American ginseng. Background technique [0002] Ginseng and American ginseng are both medicinal plants of Araliaceae. Up to now, the fresh-keeping techniques for ginseng and American ginseng mainly include: (1) Irradiation method, Xu Dechun et al. The "Preservation Method of Ginseng and American Ginseng" published in the third issue uses the method of irradiating fresh ginseng, which can keep ginseng fresh for 12 months, and the freshness rate is 97%. But this method makes ginseng easy to produce peculiar smell, and loses polysaccharide and saponin composition; In the quick-freezing room of the cold storage, add water to freeze at minus 25-30°C for 5 hours, repackage, and store in a freezer. Although this frozen preservation method keeps the original taste and active ingredients of ginseng, ginseng wil...

Problems solved by technology

[0003] It can be seen that the existing fresh ginseng fresh-keeping methods cannot completely solve the unity problem of fresh-keeping, packaging and sales of fresh ginseng, especially the problems of freshness, color and active ingredient retention of fresh ginseng.
