Method for producing fungal water-soluble haematochrome through mixed solid fermentation of wood flour

The invention relates to a method for producing fungal water-soluble haematochrome by utilizing wood flour mixed solid-state fermentation. The method comprises the following steps: (1) pretreating wood flour; (2) activating the strain; (3) preparing a wood powder mixed culture medium; (4) inoculating a fungus cake to the center of the wood powder mixed culture medium in the step (3), and culturing and fermenting in a constant-temperature and constant-humidity incubator; and (5) cutting the fermented culture medium into small blocks, pouring the small blocks into a container, adding distilled water according to a liquid-material ratio of 30: 1, sealing with a preservative film, carrying out water-bath ultrasonic extraction, filtering, bottling, and freeze-drying to obtain water-soluble haematochrome powder. The method provided by the invention is low in cost, pollution-free, efficient and stable in production of the water-soluble haematochrome. 一种利用木粉混合固态发酵生产真菌水溶性红色素的方法，包括以下步骤：(1)预处理木粉；(2)将菌种进行活化；(3)制备木粉混合培养基；
