Fruits and vegetables are an indispensable part of the daily diet, providing rich nutrients for our health. After harvesting, fruits and vegetables need to go through packaging, storage, transportation and sales before they can reach the hands of consumers.

However, the transpiration of fruits and vegetables and the relatively closed packaging environment cause the temperature and humidity of fruits and vegetables to rise during the circulation process, thereby activating the activity of pathogenic bacteria and infecting fruits and vegetables, causing a large number of fruits and vegetables to rot and deteriorate.

With the development of new technologies and new materials, new active packaging systems have shown unique advantages in the field of food preservation.

Compared with traditional food packaging, active packaging effectively inhibits the growth and activity of postharvest pathogenic bacteria by adding antibacterial active ingredients, thereby extending the shelf life of fruits and vegetables.

Based on the characteristics of the fruit and vegetable packaging environment and the perishability of fruits and vegetables, an active packaging coating with dual anti-fogging and antibacterial functions and three new intelligent response antibacterial active packaging materials were constructed, and their application in fruit and vegetable preservation was explored. .

Preservation of fruits and vegetables is very important to the storage and sales process after harvesting.

The use of scientific preservation technology can effectively extend the storage period of fresh fruits and vegetables and maintain the nutritional value of fruits and vegetables.

Faced with the two major problems of continuous active physiological metabolism and microbial contamination of fruits and vegetables after harvesting, Huacheng High-Tech has developed antibacterial fruit and vegetable fresh-keeping packaging: a fruit and vegetable fresh-keeping packaging composite film that controls the release of fungicides to achieve the dual functions of anti-fogging and antibacterial.
