Abstract

The invention, belonging to the field of food processing, particularly relates to a method for producing corn flour by using edible fungi solid state fermentation maize pulp, comprising the following steps: a, conducting mixed fermentation of ganoderma lucidum antler and hericium erinaceus liquid; b, preprocessing materials; and c, conducting solid state fermentation. According to the invention, the mixed strain of anoderma lucidum antler and hericium erinaceus prepared by the liquid strain preparation method has the characteristics of high depth, high antioxidant activity, etc.; and the corn flour prepared by fermentation contains the active components of ganoderma lucidum antler and hericium erinaceus with the functions of resisting oxidation and raising immunity based on containing corn with abundant nutrients, thereby satisfying the requirements of people for food nutrition, health, and natural.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for preparing corn flour by solid-state fermentation of corn dregs with edible fungi. Background technique [0002] Corn (scientific name: Zeamays), also known as maize, corn, corn, and cob, is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. Among the more than 50 most effective nutraceuticals and health substances proven today, corn contains 7 kinds-calcium, glutathione, vitamins, magnesium, selenium, vitamin E and fatty acids. It has been determined that every 100 grams of corn can provide nearly 300 mg of calcium, which is almost the same as that contained in dairy products. Rich in calcium can play a role in lowering blood pressure. If 1 gram of calcium is taken in every day, blood pressure can be reduced by 9% after 6 weeks. In addition, the carotene c...
