Problems solved by technology

However, the overall level of edible fungus deep processing is not high, there are few famous and high-value-added products, and there are few refined and deep-processed products, so it is difficult to meet the diverse and multi-level needs of domestic and foreign markets for edible fungi
The traditional dried, fresh and primary processed edible fungi can no longer meet the needs of consumers, and there is an urgent need for new deep-processed edible fungi

Embodiment 1

[0046] refer to figure 1 Shown flow chart, a kind of preparation method of edible fungus nutrient powder rich in amino acid, comprises the following steps:

[0047] 1) Screening of raw materials: Select fresh four kinds of edible mushrooms: shiitake mushroom, tea tree mushroom, yellow umbrella mushroom and Coprinus comatus. The meat is thick, tough and elastic, without black spots and impurities. Dry appearance, pure color, no moist feeling and no peculiar smell;

[0048] 2) Pretreatment: Rinse the edible fungus with running water, remove impurities on the surface and slice into slices with a thickness of 3-5mm;

[0049] 3) Blanching: blanching the washed edible fungus in boiling water for 2-3 minutes, and then letting it air for 10 minutes;

[0050] 4) Vacuum freeze-sublimation drying: use vacuum freeze-sublimation drying technology to process blanched edible fungi, and the vacuum degree is less than 0.08mpa;

Abstract

A preparation method of edible fungi nutrient powder rich in amino acids comprises the following steps: washed edible fungi are put into boiled water for blanching 2-3 minutes, cooled in air for 10 minutes, sliced and then dried till the water content is lower than 5% by adopting the freeze-drying technology, so as to obtain edible fungi dry products; the edible fungi dry products are pulverized in an ultramicro way, so as to obtain edible fungi powders with particle sizes less than 15 [mu]m; the edible fungi powders are compounded according to a certain proportion, so as to obtain edible fungi nutrient powder with high score in amino acids and balanced nutrition. The invention has the advantages that the edible fungi are dried by adopting the freeze-drying technology under vacuum condition and pulverized in the ultramicro way under low temperature, so that nutritional components in the edible fungi are retained to the greatest extent, and the edible fungi powders are good in fluidity,adsorbability, solubility and adsorptivity; in addition, the edible fungi powders are compounded, so as to improve the amino acid score of the compounded powder and obtain the edible fungi nutrient powder with balanced nutrition.

Description

technical field [0001] The invention relates to the field of deep processing of edible fungi, in particular to a method for preparing edible fungus nutrition powder rich in amino acids. Background technique [0002] my country is the world's largest producer and exporter of edible fungi. The edible fungus industry has developed rapidly and has become my country's fourth largest planting industry after grain, fruit and vegetables. At present, the overall level of edible fungus deep processing is not high, there are few famous and high-value-added products, and there are few refined and deep-processed products, so it is difficult to meet the diverse and multi-level needs of domestic and foreign markets for edible fungi products. [0003] Edible fungus is a nutritious food resource with high protein, high dietary fiber and low fat, and is a globally recognized "healthy food". my country is the world's largest producer and exporter of edible fungi. The edible fungus industry ha...
