Novel aspergillus flavus infection-resistant green plant polysaccharide coating for peanuts and application method thereof

Abstract

The invention discloses a novel aspergillus flavus infection-resistant green plant polysaccharide coating for peanuts, and belongs to the technical field of peanut processing and production. The novelaspergillus flavus infection-resistant green plant polysaccharide coating comprises an agent A, an agent B and an agent C. The main component required by the coating is from waste apple pomace in theapple juicing industry, the cost is low, no pollution is caused, pectic polysaccharide is used as the main component, a physical sealing mode is mainly adopted, aspergillus flavus is prevented from polluting the peanuts, and compared with other existing technologies, the coating is green and safe, and other antibacterial and insect-resistant substances can be added according to needs.

Description

technical field [0001] The invention belongs to the technical field of peanut processing and production, and in particular relates to a novel green plant polysaccharide coating for peanuts resistant to infection by Aspergillus flavus and an application method thereof. Background technique [0002] Peanut is my country's main oil crop and an important export-earning agricultural product. Peanuts are rich in nutritional value and high in oil content, and have important edible and oil value. In the production of peanuts, due to the influence of the environment, climate, and peanut drying and storage methods, they are susceptible to infection by Aspergillus flavus, which in turn produces aflatoxin pollution. The harm caused by aflatoxin contamination of crops is immeasurable, and it is one of the diseases that have a large-scale destructive effect on peanut production. [0003] Peanuts may be infected by Aspergillus flavus in all stages of production and may be contaminated wi...

Problems solved by technology

The existing peanut coating agents have the following disadvantages: large pesticide residues and high toxicity: the insecticidal or bactericidal ingredients in the currently used seed coating agents are chemical compounds with certain toxicity, which have certain toxic and side effects on humans and animals. It does not meet the requirements of modern agriculture. For example, chlorpyrifos is a poisonous pesticide, which is highly toxic to fish and aquatic organisms; it is easy to cause phytotoxicity and seed burning; if the chemical coating agent is used excessively or the temperature is low, it is easy to cause phytotoxicity. It can significantly inhibit the growth of seedlings, affect the emergence of seedlings when sowing deep, and reduce the yield

In addition, the existing coating agents are mainly seed dressings, which are rarely used for storage of postpartum peanuts, and cannot fundamentally solve the problem
