Mushroom smashing device and using method thereof
Technical Field
The invention relates to the field of mushroom processing, in particular to a mushroom smashing device and a using method thereof.
Background
The air-dried shiitake contains a large amount of glutamic acid and aspartic acid, the two amino acids have strong delicate flavors, and the amino acids are combined in the shiitake in the form of protein, so that the health of the shiitake cannot be damaged, and meanwhile, the dry shiitake powder also contains other amino acids necessary for a human body and is rich in nutrition. The mushroom powder is prepared from high-quality mushroom, is beneficial to preventing rickets caused by blood phosphorus and blood calcium metabolism disorder caused by vitamin D deficiency of human bodies, especially infants, can prevent various mucosal and skin diseases of human bodies, and has good effects of enhancing disease resistance and preventing cold after being frequently eaten. The Lentinus Edodes can be used for preventing angiosclerosis and lowering blood pressure. The ash content of the mushroom contains a large amount of potassium salt and other mineral elements, and when the mushroom is regarded as an ideal food for preventing acid food poisoning, the mushroom can be refreshed by spraying dry mushroom powder on cooked food.
