CN101836558A - Production method of selenium-rich mushroom - Google Patents

Abstract

On the basis of currently known spawn medium formulas and culturing management of various mushroom liquid prepared seeds, during the preparation of liquid spawn, selenite is additionally added in a spawn medium of liquid prepared seeds, the selenite which is dissolved in the spawn medium is sprayed in a bagged material for growing mushrooms along with a mushroom seed during grafting, which plays a decisive role in the density of the selenite in the bagged material, and thereby the selenium content of the bagged material for growing mushrooms is controlled by controlling the density of the selenite of the medium of liquid spawn, and each batch of mushrooms taking the bagged material as nutrients is ensured to contain rich selenium, and meanwhile, the selenium content of mushrooms in unit weight is stable within the required range.

Description

The production method of Se-rich xianggu

Technical field

The present invention relates to a kind of production method of Se-rich xianggu.

Background technology

Selenium is the necessary a kind of trace element of human body, and scarce selenium can cause the multiple disease of human body, and China overwhelming majority area lacks selenium, quantitatively mends selenium, and is very urgent.The scope of taking in inorganic selenium because of human body safety every day is narrower, and human body is bigger to the tolerance degree of organic selenium, is absorption of human body again after changing inorganic selenium into organic selenium, is the best approach of human body safe selenium-complement.Mushroom has very strong transformation inorganic selenium in process of growth be the ability of organic selenium, and contributes to contemporary times and brings benefits for future centuries for the exploitation Se-rich xianggu.Yet, regrettably: fail to produce in enormous quantities the stable Se-rich xianggu of selenium content in the society at present.

The invention has the beneficial effects as follows: can produce the stable Se-rich xianggu of selenium content in enormous quantities, be convenient to people and quantitatively mend selenium.

Summary of the invention

The cultivation process of the production of hybrid seeds of present known mushroom liquid, packed medium is: liquid spawn preparation, spice, pack, sterilization, inoculation, bacteria, go out ear, several links such as gather.The invention provides a kind of production method of Se-rich xianggu, the technical scheme that realizes is on the basis of the spawn culture based formulas of the known various mushroom liquid production of hybrid seeds at present and cultivation management, when liquid spawn prepares, in the bacterium culture medium of the liquid production of hybrid seeds, add selenium salt in addition, be dissolved in the selenium salt in the bacterium culture medium, when inoculation, sprayed in the sacked material of growth mushroom with the mushroom kind, concentration to the selenium salt of sacked material has played conclusive effect, the concentration of selenium salt by the control liquid spawn culture medium, thereby controlled the selenium content of the sacked material of growth mushroom, guarantee that every batch is that the mushroom of nutrient is when being rich in selenium with the sacked material, the mushroom selenium content of Unit Weight is stabilized in the required scope, is convenient to people and quantitatively mends selenium.

Specific embodiment

90Kg water and 9Kg potato boil to shortcake, add 1.35Kg brown sugar, 0.9Kg glucose, 3.6Kg wheat bran, 0.18Kg peptone, 0.18Kg potassium dihydrogen phosphate, 0.09Kg magnesium sulfate, 0.9g vitamin V B1,27 milliliters bubble enemy and 6 gram sodium selenites, filter the back the medium of liquid spawn, through sterilization and liquid-spawn inoculation cultivation, promptly finished the preparation of liquid spawn, can be the packed culture medium inoculated after spice, pack and sterilization, through bacteria, go out ear and gather, get final product to such an extent that contain the stable Se-rich xianggu of selenium.

Claims (1)

1. the production method of a Se-rich xianggu, it is characterized in that: on the basis of the spawn culture based formulas of the known various mushroom liquid production of hybrid seeds at present and cultivation management, when liquid spawn prepares, in the bacterium culture medium of the liquid production of hybrid seeds, add selenium salt in addition, be dissolved in the selenium salt in the bacterium culture medium, sprayed in the sacked material of growth mushroom the concentration of the selenium salt by the control liquid spawn culture medium, thereby the selenium content of the sacked material of control growing mushroom with the mushroom kind in when inoculation.
