Embodiment Construction

[0013] The present invention will be further explained below in conjunction with specific examples.

[0014] Selected from wild matsutake in Changbai Mountain area, screened and tested according to GB / T23188 matsutake standard, the screening principles and testing standards should meet the requirements of the standard. Use a brush and purified water to clean the soil of the wild matsutake that meets the standard requirements. After the soil is cleaned, wash the matsutake three times with purified water, put it in a tray to drain, and weigh it after draining. The washed matsutake is added to the purified water in a weight ratio of 1:2, put into a grinder and ground, and then extracted in a constant temperature water bath at 90°C for 1 hour. Then centrifuge:

[0015] ① Three-legged centrifuge: put the ground matsutake into a three-legged centrifuge for 40 minutes, and the speed of the centrifuge should reach 1400-1500 rpm.

[0016] ②Tube centrifugation: Put the three-legged ce...

Abstract

The present invention discloses a freeze-dried tricholoma matsutake powder preparation method. The tricholoma matsutake is washed and minced with water, the minced tricholoma matsutake is extracted using a constant temperature water bath, then the extracted tricholoma matsutake is centrifuged to obtain a centrifugate, and a 3-7% of freeze-dried excipient is added into the centrifugate when the polypeptide value of the centrifugate is greater than 3.0. The freeze-drying is divided into three stages: a first stage: freeze-drying at 20 to -50 DEG C for 10 to 14 hours; a second stage: freeze-drying at -50 to 50 DEG C for 32 to 36 hours; and a third stage: freeze-drying at 55-60 DEG C for 18 to 22 hours. After the centrifuge is freeze-dried, the freeze-dried centrifuge is subjected to a sterilization treatment. The freeze-dried tricholoma matsutake powder preparation method uses an advanced biological extraction and freeze-drying technology to reduce the loss of active nutrients and fully retain the nutrients and good flavor of the freeze-dried tricholoma matsutake powder.

Description

technical field [0001] The invention relates to the technical field of processing edible fungi, in particular to a preparation method of matsutake freeze-dried powder. Background technique [0002] Matsutake, the scientific name is Tricholoma matsutake, alias matsutake, genus, and Taiwan. It is a rare and precious natural medicinal fungus in the world and a second-level key protected wild species in my country. The main velvet-producing areas in my country include Shangri-La velvet-producing areas, Chuxiong velvet-producing areas, and Changbai Mountain velvet-producing areas. Matsutake contains 18 kinds of amino acids, 14 kinds of essential trace elements, 49 kinds of active nutrients, 5 kinds of unsaturated fatty acids, 8 kinds of vitamins, 2 kinds of glycoproteins, rich dietary fiber and a variety of active enzymes, and also contains 3 kinds of precious The active substances are double-chain matsutake polysaccharide, matsutake polypeptide and the world's unique anti-cance...
