Abstract

The invention discloses an aspergillus flavus infection resistance method for xanthan gum composite membrane covered peanuts, comprising the following steps of adding peanut shell powder into a citric acid solution, conducting microwave extraction, leaching and concentrating the solution; adding absolute ethyl alcohol into the solution; standing, centrifuging, precipitating, freezing and drying; smashing to obtain peanut water-soluble dietary fiber; adding the peanut water-soluble dietary fiber into distilled water, and mixing uniformly; adding the xanthan gum under a stirring condition; removing bubble in vacuum to obtain xanthan gum water-soluble dietary fiber composite membrane coating materials; coating the coating materials on peanuts; packaging the peanuts; and storing the peanut at a normal temperature. The xanthan gum composite membrane covered peanuts prepared by the method can resist the aspergillus flavus infection, restrains the growth of the aspergillus flavus, prevents the peanut fat from being oxidized and is stored for a long term and suitable for industrial production.

Description

Technical field [0001] The invention involves the method of anti -yellowed mildew -infected, which is the method of culvert composite membrane coating peanuts, which belongs to the field of food storage and processing. Background technique [0002] Peanuts are crops of peanuts, rich in oil and protein, and are important oil crops and crops in my country.Due to climatic factors and the influence of the cultivation and storage methods of farmers, peanuts are susceptible to pollution of mulbidal toxin, causing huge economic losses.Aflatoxin (AFT) is a type of fungal toxin that can cause carcinogenic, teratogenic, and mutations. It is a promotional factor for the explosion of multiple viral diseases. The target organs that have the role of yellow glimading toxin are liver, which is the liver.The harm is very serious.At present, the storage conditions of low temperature, dryness, and ventilation and ventilation can be guaranteed to ensure that peanuts are exempted from yellow mold inf...
