Freshness-keeping method for fresh branches of dendrobium officinale

Abstract

The invention provides a freshness-keeping method for fresh branches of endrobium officinale. The fresh branches of the endrobium officinale are subjected to freshness-keeping by virtue of technologies such as ozone disinfection, air-cooling and drying, dry ice gas regulation and constant-temperature regulation, so that physiological activities of the fresh branches of the endrobium officinale are reduced, bacterial microorganisms are prevented from infecting fresh branches of the endrobium officinale, and therefore, freshness-keeping storage time of fresh branches of the endrobium officinale is prolonged. Compared with a conventional freshness-keeping method, the freshness-keeping method provided by the invention has the advantages of not containing chemical medicine residues, being high in safety, adopting single and easy-to-operate equipment and technology, being low in freshness-keeping cost, being capable of keeping freshness on a large scale, being suitable for being implanted in an endrobium officinale planting base, and the like.

Description

technical field [0001] The invention relates to the technical field of preservation of fresh Chinese medicinal materials, in particular to a fresh-keeping method for fresh branches of dendrobium officinale. Background technique [0002] Dendrobium officinale is a traditional precious and rare medicinal material, known as "the gold in medicine", and is honored as the first of the "Nine Chinese Immortal Herbs" in the Taoist classic "Tao Cang". As of 2014, the planting area of ​​Dendrobium officinale in my country has exceeded 2 667hm 2 , and the cultivation area has increased year by year, and the cultivation level has been continuously improved. Planting Dendrobium officinale has become a new bright spot for increasing agricultural efficiency and increasing farmers' income. People are more willing to buy fresh or maple buckets than finished products, because the authenticity of these products can be seen. It has become a fashion to use fresh Dendrobium officinale, maple bu...

AI Technical Summary

Problems solved by technology

The fresh-keeping process of the coating film is cumbersome, and if the fresh-keeping technology of the coating film is used improperly, it will have an adverse effect on the fresh-keeping storage, such as insufficient disinfection of the storage environment and fresh branches of Dendrobium candidum, or the fresh branches of Dendrobium candidum are infected with bacteria. Chitosan, starch, etc. are good culture media for microorganisms, which often cause the coating material to be polluted first, and then cause the fresh branches of Dendrobium officinale to rot and deteriorate.

The storage environment gas adjustment equipment in the modified atmosphere preservation technology, the vacuum device and the ultra-low temperature warehouse configuration involved in the quick-freezing preservation technology have high requirements on the hardware equipment required for fresh-keeping storage, and the fresh-keeping cost of Dendrobium candidum during storage is high. Dendrobium officinale planting bases generally do not have the corresponding fresh-keeping conditions

At the same time, most of the above fresh-keeping technologies and results are based on small-scale experiments, and technologies that can be applied on a large scale in production have not yet been reported.
