Method for preparing edible fungus strains

Abstract

The invention provides a method for preparing edible fungus strains. The method comprises the following steps: pretreating raw materials: selecting edible fungi, carrying out sorting treatment, removing moldy areas, and separating mycelia from stalks; carrying out instant blanching: putting the edible fungi into boiling water, carrying out ultrasonic blanching for 3 to 5 minutes, and rapidly taking out the blanched edible fungi; preparing bamboo fungus water: washing bamboo fungi, chopping the washed bamboo fungi, adding a proper volume of water into the chopped bamboo fungi, carrying out ultrasonic crushing for 15 minutes, carrying out stirred lixiviating for 30 minutes in water bath of 80 DEG C, repeatedly carrying out lixiviating for 3 times, and merging supernatant; precooling the bamboo fungus water obtained in the step (3) to 0 DEG C; carrying out vacuum freeze-drying treatment; and carrying out sealed packaging for sale. According to the method, the treatment steps are simple, and nutrients of the edible fungi are reserved to the maximum; by using instant blanching and vacuum fast-freezing jointly, the taste of the edible fungi can be kept tender and brittle; and the bamboo fungus water is selected as a substitute of antiseptics, so that the product is natural, healthy and additive-free, and the preservation effect is good.

Description

technical field [0001] The invention relates to the cultivation industry of edible fungi, in particular to a method for preparing edible fungus strains. Background technique [0002] Edible fungi are a class of large fungi that can be used for human consumption or medicine. Animal food, plant food and fungal food are the three major types of food for humans. Edible fungi contain a large amount of amino acids, cellulose and trace elements, with special flavor and smooth taste. They also contain special bacterial proteins and a variety of biologically active substances, such as: polymer polysaccharides, RNA complexes, nucleic acid degradation products, etc. The nutritional structure and content are most similar to the needs of the human body. [0003] At present, the deep processing methods of edible fungi mainly include drying method and pickling method. Vacuum freeze drying, hot air drying, infrared radiation drying, microwave vacuum drying, etc. are generally used for dryi...

Problems solved by technology

[0003] At present, the deep processing methods of edible fungi mainly include drying method and pickling method. Vacuum freeze drying, hot air drying, infrared radiation drying, microwave vacuum drying, etc. are generally used for drying, but there are many defects in them, such as high energy consumption, uneven drying, Easy to burn, bad taste, etc.

The pickling method is also a common way to extend the storage period, but adding a large amount of preservatives is more harmful to the human body. Now it is gradually looking for alternatives and further improving the deep processing technology
