Problems solved by technology

Sodium bisfolinate is mainly used in the feed. The shortcomings of these anti-mold (rot) agents are the use of a single agent, the effect of the agent is single, the validity period is short, the amount of use is large, and the anti-mildew (rot) effect is poor. and:
[0004] 1. It must be evenly added to the materials that need anti-mold (rot) agents. The existing anti-mold (rot) agents have certain toxicity. They are directly added to the materials and then ingested into the human body and animals together with the items. There is a certain degree of toxicity. security issues
[0005] 2. When used, it is affected by the pH value (PH value) of the item, which affects the effect of anti-mildew (rot)
[0006] 3. It has an impact on the flavor of food
[0007] 4. The antibacterial effect of a single agent has a short period of validity, but it is easy to agglomerate and turn black and reduce the antibacterial effect
[0008] 5. Fumarate esters have itchy, red, swollen and allergic reactions to human skin

Abstract

A gas-phase antiseptic, antimildew and antistaling agent with high safety and effect and broad spectrum for grain tobacco, medicine, vegetables, clothes, etc is prepared from methyl fumarate, dimethyl fumarate, calcium propioate, VC or VE, benzoic acid and nipagin ester through dissolving in alcohol, heating natural cooling while crystallizing, drying in air, pulverizing and packing in sealed mode.

Description

technical field [0001] The invention belongs to the technical field of anti-mildew, anti-corrosion and fresh-keeping agents, and relates to a composite gas-phase anti-mold, anti-corrosion and anti-corrosion preservative and its manufacturing method and application, in particular to a mildew-proof, anti-corrosion and fresh-keeping agent for tobacco leaves. Background technique [0002] In the past, in order to keep fresh and store agricultural products, especially tobacco leaves, various organic esters and organic salt solutions were usually used to fumigate or spray to prevent stored agricultural products, tobacco leaves, etc. Toxicity: After the organic salt solution dries, the residues on the agricultural products are difficult to remove, and the residues of organic esters on the agricultural products are easy to volatilize. However, during the delivery process, they will have a strong stimulating effect on the skin, eyes, and nasal cavity of the construction workers, and w...
