Method for carrying out uniform selenium-enriched cultivation of pleurotus geesteranus by using selenium yeast

Abstract

The invention discloses a method for carrying out uniform selenium-enriched cultivation of pleurotus geesteranus by using selenium yeast, which is characterized by comprising steps of mixing a selenium-enriched cultivation material additive of which the weight is 1-10 percent of the total weight of a cultivation drier into the cultivation drier and carrying out cultivation according to a common cultivation method to obtain the uniform selenium-enriched pleurotus geesteranus, wherein the total content of selenium in the selenium-enriched cultivation material additive is in the range of 5-200mg / kg; the diameters of particles in the selenium-enriched cultivation material additive are distributed in a multiple diameter region mode in the range of 0.005-5.0mm; the weight of the particles with the diameter in the range of 1.0-5.0mm is at least 10 percent of the total weight of the additive; the weight of the particles with the diameter in the range of 0.005-0.1mm is at least 40 percent of the total weight of the additive; and the selenium-enriched cultivation material additive comprises the following composition raw materials in parts by weight: 100 parts of maize cob meal and 0.45-18 parts of selenium yeast. The pleurotus geesteranus obtained by using the method has high selenium utilization rate and stable selenium content between batches. Moreover, the method has no hidden dangerof selenium pollution and is convenient to operate and easy to popularize.

Description

technical field

[0001] The invention relates to edible fungi, in particular to a method for strengthening the selenium nutrition of Pleurotus chinensis by using selenium yeast as a selenium source, and belongs to the technical field of biotransformation of selenium resources. Background technique

[0002] Pleurotus geesteranus belongs to the Phylum Fungi, Basidiomycetes, Agaricaceae, Pleurotaceae Pleurotus in taxonomy. Xiuzhen mushroom is crisp and tender in texture, sweet and refreshing, has a pleasant crab fragrance, is rich in nutrition, has high edible and medicinal value, and is an excellent strain in Pleurotus spp. It is a high-protein, low-fat nutritious food. Its protein content is close to that of meat, 3-6 times higher than that of ordinary vegetables, and its texture is tender and low in fiber content. Threonine, lysine, and homopic acid cannot be produced, and are usually lacking in food. This kind of edible fungus gets its name because of its beauty and precio...
