AI Technical Summary

Problems solved by technology

[0003] Due to the harsh growth conditions of natural Cordyceps sinensis, the scattered and remote places of production, and the inaccessibility of people, the water loss of wild Cordyceps sinensis is very fast after excavation. It is impossible to process or prepare color protection liquid in a very short time, which leads to the decline in the quality of Cordyceps sinensis products.
The patent application "a biological freeze-drying method of Cordyceps sinensis", the patent number is 200710011666.7, uses fresh Cordyceps sinensis as raw material, absorbs 70% of water to restore the shape, and then adopts quick-freezing machine and automatic control vacuum drying equipment to freeze-dry and store. What method is used to absorb water, but judging from the existing conventional processing methods, it is generally used to absorb water by soaking when cleaning the sediment. The disadvantage of this method is that the active ingredients of Cordyceps sinensis are leached and lost in water. Reduced the quality of Cordyceps
"The disadvantage of this application is that the addition of color protection liquid does not really reflect the value and efficacy of pure wild Cordyceps sinensis, and the addition of artificially synthesized ingredients loses the expensive value of pure wild Cordyceps sinensis

Embodiment 1

[0019] 1.1 Water absorption and reshaping: put the pretreated Cordyceps sinensis on a fence-type drying rack, spread it flat, put it in a closed room, use an ultrasonic humidifier to spray and humidify it, and take a sample after a period of time to test its moisture content. When the moisture content When it reaches 75%, the spray heating can be stopped. The specifications of the ultrasonic heater are selected: the atomized water molecule temperature is 0-3°C, and the particle size is 1-5 microns.

[0020] 1.2 Quick freezing: Put it in a quick freezer for quick freezing, and freeze it at -50°C for 3 hours.

[0021] 1.3 Vacuum freeze-drying: in a vacuum freeze dryer, vacuum freeze-dry at -45°C for 16 hours,

[0022] 1.4 Finished product testing: the moisture content of the finished product reaches 7%.

[0023] 1.5 Packaging and storage.

Abstract

The invention relates to aweto biological vacuum freezing and drying method, belonging to the field of preservation method of animals and plants. The aweto biological vacuum freezing and drying method comprises the steps as follows: (1) the aweto absorbs low-temperature atomized water molecular, the water absorption is 75-80%; (2) quick freezing is carried out for 2-5 hours at the temperature of -50-55 DEG C; (3) the vacuum freezing and drying are carried out for 2-20 hours at the temperature of -45-55 DEG C, so as to lead the moisture content of the finished product to achieve 5-9%. The product obtained by the invention can achieve sanitary requirement of edible fungi which can be directly eaten; the product has good water absorption, really achieves the original shape, colour, tastes and nutritive effect of purely wild aweto, improves the real additive values of the aweto and is suitable for long-term storage.

Description

technical field [0001] The invention relates to the field of animal and plant material preservation, in particular to a biological vacuum freeze-drying method for Cordyceps sinensis. Background technique [0002] Cordyceps sinensis, referred to as - Cordyceps. As the name suggests, it is a worm in winter and a grass in summer; Cordyceps sinensis is an excellent combination of animals and plants in nature, and its effect on the human body is unique. "Materia Medica Congxin" records: "Cordyceps sinensis has the miraculous effects of nourishing lung yin, tonifying kidney yang, relieving cough and reducing phlegm." Cordyceps sinensis has unique functions of yin and yang, and it is a precious medicinal material that balances yin and yang. It is listed as the three major tonics together with ginseng and velvet antler. Authorities in modern medical research have also found that Cordyceps sinensis can indeed improve the body's immune function and enhance disease resistance. It is ...
