Abstract

The invention discloses a method using high-selenium edible fungus to extract selenium-rich edible fungus leaching liquid. The method comprises the following steps of A, culturing of entities of high-selenium edible fungus; B, rinsing and drying of the entities of the high-selenium edible fungus; C, crushing of the entities of the high-selenium edible fungus; D, dissolving and ultrasonic treatment; E, enzymolysis; F, enzymolysis again; G, filtering and concentration. The method has the advantages that the high-selenium edible fungus produced by the method has rich flavor, high selenium content, rich polypeptides and multiple free amino acids, and the added value of the edible fungus is improved.

Description

technical field [0001] The invention relates to a method for extracting selenium-enriched edible fungus leachate by using high-selenium edible fungi, which belongs to the field of biotransformation of selenium resources. Background technique [0002] Selenium is an essential trace element for the human body and an essential component of glutathione peroxidase. Selenium has an antioxidant effect and is closely related to human health. Selenium has anti-cancer, heart protection, anti-hepatic necrosis, prevention and treatment of myopia and cataracts, It has multiple pharmacological effects such as detoxification, improving immunity, delaying aging and enhancing reproductive function. According to incomplete statistics, there are more than 40 countries and regions lacking selenium in the world, and 72% of the regions in my country are selenium-deficient areas. Scientists pay attention [0003] Edible fungi are a large class of edible fungi, which are rich in nutrients such as ...
