Abstract

The invention discloses a method for cultivating oyster mushroom uniformly rich in selenium with sodium selenite as the selenium source. The method is characterized in that the method comprises the steps of mixing selenium-rich cultivating material additive accounting for 1-10 percent of the total weight of dried cultivating material into the dried cultivating material, and cultivating oyster mushroom according to an ordinary cultivation method to obtain oyster mushroom uniformly rich in selenium; the selenium-rich cultivating material additive has a total selenium content of 5-500 mg / kg, thegrain sizes of the particles in the selenium-rich cultivating material additive are in the range of 0.005-5.0 mm with multi-grain-size regional distribution, the particles having a grain size of 1.0-5.0 mm account for at least 10 percent of the total weight of the additive, while the particles having a grain size of 0.005-0.1 mm account for at least 40 percent of the total weight of the additive;according to the respective parts by weight portions, the raw materials of components used in the selenium-rich cultivating material additive comprise 100 portions of cotton shells and 0.0011-0.11 portion of sodium selenite. The method has the advantages that the selenium utilization factor in oyster mushroom is high, and the selenium content in different batches of oyster mushroom is stable; besides, the method has no potential danger of selenium pollution, is convenient to operate, and easy to promote.

Description

Technical field [0001] The invention relates to a method for fortifying selenium nutrition of edible fungi, in particular to a method for strengthening selenium nutrition of oyster mushroom with sodium selenite as a selenium source, and belongs to the technical field of biological transformation of selenium resources. Background technique [0002] Selenium is an essential trace element for the human body. The lack of selenium will significantly reduce the body's immune capacity, and selenium-deficient areas are prone to endemic diseases such as Keshan disease, Kashin-Beck disease and cardiovascular and cerebrovascular diseases. Appropriate amount of selenium supplementation can significantly improve cancer, cataracts, and child malnutrition, and can avoid arteriosclerosis, hypertension, myocardial infarction, senile neurological insufficiency, memory and intellectual impairment caused by fibrosis of the cardiovascular and cerebrovascular walls The occurrence of the disease. Sele...
