Method for improving yield and trace element enrichment of liquid fermentation mycelium of lucid ganoderma

Abstract

The invention relates to the field of liquid fermentation mycelium of lucid ganoderma and provides a method for improving yield and trace element enrichment of the liquid fermentation mycelium of the lucid ganoderma. The method is characterized by comprising the steps of inoculating a slope lucid ganoderma strain onto a liquid seed culture medium added with trace element-containing substances, performing mutation breeding by ultraviolet rays and cobalt-60 gamma rays, placing the lucid ganoderma mycelium into a fermentation tank for expansion breeding step by step, and performing separation filtering, vacuum microwave drying and crushing on the lucid ganoderma mycelium to obtain a product. The method adopts the fermentation process controlled by adopting pH value steady state feedback step by step according to the composition and distribution of the trace elements in the culture medium, thus more facilitating improving the conversion efficiency of multiple trace elements; the process is efficient and controllable, and the mycelium is high in additional value and suitable for process production; and the drying method for the mycelium adopts hot wind combined with a vacuum microwave drying technology and keeps the biological activity of effective constituents in the mycelium.

Description

technical field [0001] The invention relates to the field of ganoderma lucidum liquid fermentation mycelia, and relates to a method for improving yield and enriching trace elements of ganoderma lucidum liquid fermentation mycelium. Background technique [0002] With the rapid development of my country's economy and the improvement of people's awareness of healthy living, under the current fast-paced working style, the metabolic disorders caused by the bad living habits formed by different groups of people lead to the reduction of trace element intake and cause diseases. One of the reasons is that people's diet structure is unreasonable, and the loss of nutrients and trace elements caused by too fine food processing methods. Therefore, one of the current hot spots in nutrition research is to develop and promote dietary fortification products that are highly nutritious, non-chemically synthesized, and suitable for digestion and absorption, so as to achieve the purpose of a diet...
