Detailed Explanation of Wheat Grain Germination Methods and Operating Steps
The improved method is: let the wheat grains germinate before bottling and sterilizing. The storage substances in wheat grains are mainly starch, fat and protein. When the seeds imbibe water and cell physiological activity is reactivated, the activity of various enzymes increases. During germination, these substances are decomposed into simple-structured substances such as maltose, sucrose and amino acids, which are easily utilized by the mycelium, so the mycelium grows quickly. The specific procedure is: let the wheat grains used for spawn germinate all at once, with the sprouts reaching 1-2 times the length of the wheat grains, then dry them thoroughly in the sun for storage. On the day before making the spawn, soak the wheat grains for 12h and directly bottle
