Problems solved by technology

[0002] Corn is one of the main grain crops in my country. Corn contains a large amount of lecithin, linoleic acid, grain alcohol, vitamin E and cellulose. It is recognized by nutritionists as the staple food with the highest nutritional value and health care value. However, corn contains The content of lysine and tryptophan is low, and the taste is rough, which limits the application of corn in daily staple food
At present, researchers have increased the content of lysine and tryptophan in corn by adding Hericium erinaceus strains to the compound solid medium of corn and soybean for fermentation to improve the rough taste of corn, but the fermentation time is relatively long. Long, and with the prolongation of the storage time, the beany smell of the obtained fermented corn flour is increasing. After about 1 month of sealed storage, the beany smell is already very obvious, and the sensory acceptance is not high.

Abstract

The invention discloses a preparation method of corn functional fungus food. The method comprises the following steps of 1, cleaning, soaking and filtering 100 parts by weight of corns, adding 7-8 parts by weight of pumpkin pulp powder, 2-2.6 parts by weight of pumpkin seed and peel powder, 0.15-0.2 part by weight of magnesium sulfate heptahydrate and 0.08-0.14 part by weight of potassium dihydrogen phosphate into filtrate, adjusting the water content to be 55-65%, carrying out high-pressure sterilization, and performing cooling to obtain a solid culture medium; 2, adding 5-10 parts by weightof liquid activated edible fungi into the solid culture medium, performing uniform stirring, performing culture for 7-12 days, and taking out a culture medium, namely obtaining the fermentation culture medium; and 3, drying and crushing the fermentation culture medium to obtain the corn functional fungus food. The invention also discloses the corn functional fungus food prepared by the preparationmethod of the corn functional fungus food. The preparation method disclosed by the invention is simple and short in production cycle, the content of lysine, tryptophan and soluble dietary fibers in the prepared corn fungus food is remarkably increased, and the corn fungus food is fine and smooth in mouth feel and good in taste and smell.
