Controlled atmosphere storage process of such Chinese herbal medicines as corn cervi pantotrichum, oviductus ranae and odobenus rosmarus

Abstract

The invention discloses a controlled atmosphere storage process of such Chinese herbal medicines as corn cervi pantotrichum, oviductus ranae and odobenus rosmarus. The process comprises the following steps: (1) bagging: dry products of Chinese herbal medicines are loaded into controlled atmosphere bags; (2) gas distribution: the needed controlled atmosphere ratios of N2: (47-59)%, O2: (1-3)% and CO2: (40-50)% are prepared by a gas distribution machine, and are gas volume ratios; (3) inflation: the bagged Chinese herbal medicines are inflated by a controlled atmosphere packing machine; (4) packing: the inflated Chinese herbal medicines are packed by an aluminum nail sealing machine; (5) disinfection: the dry products of the Chinese herbal medicines loaded into the controlled atmosphere bags are ultravioletly disinfected, and are irradiated for 4-5 min by a 20 W ultraviolet lamp according the distance of 1+- 0.1 m; and (6) warehousing: the disinfected packed products are conveyed into a dry warehouse for storage. The controlled atmosphere storage process can prolong the storage period of the Chinese herbal medicines, prevents the loss of effective components due to the damp, the mould and the volatility, and prevents the Chinese herbal medicines from being damaged by insects.

Description

Technical field: [0001] The invention belongs to the technical field of storage and preservation of traditional Chinese medicinal materials, and in particular relates to a controlled-atmosphere storage process for traditional Chinese medicinal materials such as velvet antler, clam oil and hippocampus. Background technique [0002] my country is a big country in the industry of traditional Chinese medicinal materials, and it is also its largest consumer market. Due to the rise of the wave of science and technology, traditional Chinese medicine has once again become a popular industry for investment and market operation in the 21st century. Many regions have positioned it as a pillar industry for economic development. However, Chinese herbal medicines are susceptible to insect damage, mildew, browning, and weathering during storage, which will directly affect the yield and quality of Chinese herbal medicines and threaten the sustainable development of the Chinese herbal medicin...

Problems solved by technology

However, Chinese herbal medicines are susceptible to insect damage, mildew, browning, and weathering during storage, which will directly affect the yield and quality of Chinese herbal medicines and threaten the sustainable development of the Chinese herbal medicine industry.

Nowadays, the dried antler, toad oil, and hippocampus of Chinese medicinal materials in the market are mainly bulk goods. Generally, the dried products of Chinese medicinal materials are directly packed into transparent large plastic bags, and then tied with a rope and placed in a cool and dry place. The advantage is that it is simple and convenient, and it only needs to be packed in a plastic bag. The disadvantages are: limited storage effect, easy to be affected by moisture and mildew, easy to lose volatile active ingredients, and easy to suffer from insect damage

This method has little effect on velvet components and is easy to operate; however, the equipment investment is high, maintenance is difficult, and gamma rays have radiation effects on the human body, so it is difficult to popularize

[0007] Modified atmosphere packaging technology is a new technology developed in recent years. Now it has been used in the storage and preservation of fruits and vegetables, chilled meat, grain, and Chinese medicinal materials. 2 Concentration-sensitive, it can inhibit and kill pests and molds in Chinese medicinal materials by changing the gas ratio in the storage space of Chinese medicinal materials, and prevent them from mildew, insects, and damp seedlings by improving pre-treatment and packaging processes, and modified atmosphere packaging The technology is non-toxic, harmless and has no residue, but there are still many shortcomings in this technology: large investment in controlled atmosphere storage equipment, complicated system, high investment, different technical solutions for different storage objects, complicated procedures, and difficult operation and maintenance. High cost greatly limits the popularization and application of this technology
