Problems solved by technology

Therefore, when the food is in an environment with suitable oxygen and moisture, microorganisms will multiply in the food, causing the food to go moldy and lose its original value.
[0003] In the process of production and storage, it is inevitable that food will be moldy due to the action of microorganisms. In this process, various toxic substances will be produced. These toxic substances will bring great harm to people's health and cause great losses to people's production. , and the synthetic antifungal agents commonly used in the industry often bring certain adverse effects to human health and the environment

preparation example Construction

[0035] See figure 1 , A method for preparing a natural anti-mildew and fresh-keeping paint in an embodiment includes the following steps S110-S130.

[0036] S110: Provide raw materials, including: 30%-60% of main components, 0.1%-10% of natural extract antifungal agents and 30%-65% of solvents by mass percentage.

[0037] Specifically, the main component is selected from at least one of modified starch, water-soluble chitosan, modified agar, modified rosin and rosin derivatives, and the solvent is water or / and ethanol.

[0038] S120: uniformly mixing the main component and the solvent to obtain a mixed liquid.

[0039] It can be understood that in order to accelerate the dissolution, heating, stirring or ultrasonic treatment can be used during the mixing process.

[0040] S130: uniformly mixing the mixed solution and the natural extract antifungal agent to obtain a natural antimold and fresh-keeping coating.

[0041] Specifically, the condition for mixing the mixed liquid a...

Embodiment 1

[0049] The raw materials are provided, and the content by weight percentage includes: 30% of water-soluble chitosan, 9% of capsaicin, 0.5% of catechin, 0.3% of allicin, 0.2% of xanthanin and 60% of water.

[0050] Add the water-soluble chitosan and water into the reaction kettle, stir and mix evenly to obtain the mixed solution.

[0051] At a stirring speed of 800r / min, add capsaicin, catechin, allicin and xanthoxylin into the mixture successively dropwise. After the dropwise addition, continue to stir for 6 hours and mix evenly to obtain a natural anti-mold fresh-keeping coating.

[0052] The natural anti-mold and fresh-keeping paint is pressed at 5g / m 2 A large amount of coating on the PE film, made of anti-mildew plastic wrap.

Embodiment 2

[0054] The raw materials are provided, and the content by weight percentage includes: 40% of water-soluble chitosan, 3% of capsaicin, 0.4% of catechin, 0.3% of gingerol, 0.2% of xanthanin, 0.1% of allicin and 56% of water.

[0055] Add the water-soluble chitosan and water into the reaction kettle, stir and mix evenly to obtain the mixed solution.

[0056] At a stirring speed of 1000r / min, add capsaicin, catechin, gingerol, allicin and xanthoxylin into the mixture successively. After the addition, continue to stir for 4 hours and mix evenly to obtain the natural anti-inflammatory agent. Mildew preservation coating.

[0057] The natural anti-mold and fresh-keeping paint is pressed at 5g / m 2 A large amount of coating on the PE film, made of anti-mildew plastic wrap.

Abstract

The invention relates to a natural mildew-proof fresh-keeping coating, and a preparation method and application thereof. The natural mildew-proof fresh-keeping coating comprises the following raw materials in percentage by weight: 30-60% of main components, 0.1-10% of a natural extractive mildew-proof agent, and 30-65% of a solvent. The main components are at least one selected from the group consisting of modified starch, water-soluble chitosan, a modified agar substance, modified rosin, and rosin derivatives. The solvent is water or / and ethanol. The natural mildew-proof fresh-keeping coatinghas good film-forming property, can form a mildew-proof fresh-keeping coating with a compact surface, few pores, and good stability, and achieves the effect of keeping moisture constant and keeping fresh and keeping moisture. The natural extractive mildew-proof agent is sufficiently dispersed in the main components, so that microbes can be effectively eliminated or the microbes can be prevented from sprouting so as to prevent the mould from growing and breeding, thereby a long-term stable mildew-proof and fresh-keeping effect is realized. Besides, raw materials of the coating are green and non-toxic substances, so that the coating also has the characteristics of non-toxicity, high safety.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a natural anti-mildew fresh-keeping coating and its preparation method and application. Background technique [0002] As we all know, microorganisms widely exist in nature, and the growth and reproduction of microorganisms are very strong in an environment with sufficient nutrients, water and oxygen. Food itself contains protein, sugar and other components, which provide good nutritional conditions for the growth and reproduction of microorganisms. Therefore, when the food is in an environment with suitable oxygen and moisture, microorganisms will multiply in the food, causing the food to go moldy and lose its original value. [0003] In the process of production and storage, it is inevitable that food will be moldy due to the action of microorganisms. In this process, various toxic substances will be produced. These toxic substances will bring great harm to people's...
