Vacuum refrigerating and drying method for wild aweto

Abstract

The present invention discloses a vacuum freeze drying method of wild cordyceps sinensis, which pertains to the field of medicinal materials processing. The preparation steps are that: collection of fresh cordyceps sinensis arrow preparation of color protecting reagent arrow color protection arrow prefreezing arrow vacuum freeze drying arrow final product of the cordyceps sinensis arrow packaging and preservation. Cordyceps sinensis dried by adopting the invention can maintain the original physical activity to the maximum, thus enabling a variety of natural functional elements contained in the cordyceps sinensis to be protected to the maximum during the drying process, which can not only maintain the natural shape unchanged basically, but can also improve the organoleptic quality, thereby solving the technical barriers of the poor organoleptic indicators and difficult preservation of the functional elements of the cordyceps sinensis after drying. The product obtained has stable quality and safety, which realizes the value increase of the cordyceps sinensis and has huge economic benefits and market development prospects.

Description

technical field [0001] The invention relates to a drying method for wild Cordyceps sinensis, in particular to a method for drying fresh Cordyceps sinensis by vacuum freeze-drying technology, which belongs to the field of medicinal material processing. Background technique [0002] Cordyceps sinensis, also known as "Cordyceps" and "Cordyceps", is a combination of insects and fungi. Known as the "King of Kings". There are more than 300 species of Cordyceps sinensis in the world, but only the Cordyceps sinensis produced in the Qinghai-Tibet Plateau of my country has truly unique medicinal value, and the demand at home and abroad is increasing, and it is a specialty of China. The medicinal Cordyceps sinensis is suitable for growing on the grass slopes near the alpine grassland shrub belt at an altitude of 3000 to 5000 meters. Its shape is like an old silkworm, with a yellowish brown surface, many wrinkles on the back, and eight pairs of legs on the abdomen; its cross section is...

Problems solved by technology

However, the efficiency of drying Cordyceps in the sun is low, the water content is not easy to control, the size of Cordyceps shrinks during the drying process, the color browns seriously, and it is also susceptible to harmful microbial contamination. The above factors lead to the low sales level of Chinese Cordyceps products in the international medicinal material market , lack of competitiveness

At present, there is no ideal and effective method for drying Cordyceps to solve this technical problem.
