Production method for high-quality sporophore of cordyceps militaris(L.)Fr. allowing carotenoid and cordycepin contents to be simultaneously increased

Abstract

The invention discloses a production method for a high-quality sporophore of cordyceps militaris(L.)Fr. allowing carotenoid and cordycepin contents to be simultaneously increased. A cultivation methodprovided by the invention divides a cultivation process of the sporophore of the cordyceps militaris(L.)Fr. into four different stages including spawn runing, primordium differentiation, sporophore growth and accumulation of metabolites, and temperature, light and humidity control are separately performed on the different stages. In the stages of the sporophore growth and the accumulation of themetabolites, based on white light irradiation, Led blue light irradiation is supplemented by utilizing a blue light strip, and sporophore samples are dried at low temperature by employing hot air or freeze-dried. By utilization of a conventional culture medium and through control of culture conditions by stages, a product of the sporophore of the cordyceps militaris(L.)Fr. is produced and obtained, allows carotenoid and cordycepin contents to be simultaneously increased, is deep yellow or orange in color, is good in appearance, and is high in commodity value, and the production method is simple and easy to implement, and can achieve high-quality production of the sporophore of the cordyceps militaris(L.)Fr..

Description

technical field [0001] The invention relates to a method for cultivating fruit bodies of Cordyceps militaris, in particular to a method for producing high-quality fruit bodies of Cordyceps militaris by simultaneously increasing the contents of carotenoids and cordycepin. Background technique [0002] Cordyceps militaris (L.) Fr., also known as Cordyceps militaris, is a rare edible and medicinal fungus with high nutritional value and nourishing effect. Biological taxonomy belongs to Ascomycota, Ascomycetes, Hypocreales, Cordicipitaceae, Cordyceps (Fr.) Link]. "Compendium of Xinhua Materia Medica" stated that Cordyceps militaris "whole herb: sweet in taste, flat in nature. It is beneficial to the lungs and kidneys, nourishes the essence, stops bleeding and resolves phlegm." Modern pharmacological research has also confirmed that Cordyceps militaris is anti-tumor, anti-virus, and lowers blood pressure. and other functions. Because its nourishing effect and medicinal effect ar...
