Abstract

The invention provides a long-acting bacteriostatic agent, an ivory board and a preparation method thereof. The ivory board comprises a cardboard base layer and a bacteriostatic coating, and the frontface and/or the back face of the cardboard base layer are/is coated with the bacteriostatic coating. A bacteriostatic agent in the bacteriostatic coating is prepared from the following components inpercentage by mass: 5-10% of organic iodine, 3-20% of polysaccharide sulfate, 5-20% of fucoidan, 1-8% of mannitol, 1-15% of micromolecular trehalose and 2-80% of soluble seaweed starch. The bacteriostatic coating is formed on the surface of the paper in a single or multiple coating mode, so that the surface of the paper has food-grade long-acting antibacterial performance, the water-based bacteriostatic coating agent coats the paperboard base layer when the paperboard base layer is produced, the technological process can be shortened, the production cost is saved, and the produced bacteriostatic ivory board ensures food safety, can be naturally degraded, and is beneficial to recycling.

Description

【Technical field】 [0001] The invention relates to paper antibacterial technology, in particular to a long-acting antibacterial antibacterial agent, white cardboard and a preparation method thereof. 【Background technique】 [0002] As we all know, food is easily affected by external factors such as physics, chemistry and biology in the links of production, processing, transportation and storage, resulting in a decrease in its quality, and packaging can not only avoid the adverse effects caused by the above factors, It also imparts an aesthetic appearance to the food product. [0003] From the perspective of the root cause of food spoilage, microbial activity is the main cause of its quality decline. Therefore, the use of antibacterial packaging to control microorganisms in food preservation is one of the important ways to extend the storage period of food. But at this stage, food processors only control microorganisms through simple pasteurization and adding preservatives to ...
