Recently, a scientific achievement named “Development and Industrialization of Preservative and Anti-mildew Film for Agricultural Byproducts” has passed the evaluation by experts from Hunan Food Science and Technology Association in Changsha. According to the experts, this film will provide a new and reliable method to reduce the risk of food damage.
This film was co-developed by Changde Jinde Laser Technology Co.,Ltd, Harbin Institute of Technology and Hunan Agricultural University, and took them five years to complete the research. It combines the paint with preservatives and anti-mildew agent to form an environmental protection coating. In this technique, the coating process and microcapsule granulation technology were used for the first time to apply functional materials on the polyethylene film at home and abroad. By painting this functional coating on the surface of the polyethylene film and making different adjustments according to different food’s requirements, the film can retain freshness and have anti-mildew, anti-fog and other properties.
Before the assessment, the technology has already been applied in many companies and organizations including Beijing Capital Agribusiness Group, Beijing Vegetable Basket Program, Xiangtan Binzhilang Food Company, Hunan Kouweiwang Group, Inner Mongolia Fengzhen Moon Cake Association, and Inner Mongolia Zhang Jintao Smoked Chicken Company. It shows good reproducibility, high maturity and great economic efficiency. For example, for dried fruits, the barrier property can be increased by 2 to 4 times compared with the regular packaging materials, the freshness preservation time can be extended by 1 to 3 times, and the anti-fogging effect will be increased by 80%.
The expert team led by Chen Kefu, an academician of the Chinese Academy of Engineering, unanimously believes that the preservative and anti-mildew film is a sophisticated and innovative, and has reached an internationally advanced level. They recommended the technology to be industrialized as soon as possible.
