Fresh-keeping and anti-mold film technology can extend the duration of fresh-keeping by 1 to 3 times

[China Packaging News] A scientific and technological achievement called "Development and Industrialization of Fresh Food and Anti-mildew Films for Series of Food (Agricultural and By-products)" passed the expert review organized by the Hunan Food Science and Technology Society in Changsha today. By-products) Loss and reduction of quality and safety risks provide new and reliable options.

This fresh-keeping and anti-mold film was jointly developed by Changde Jinde New Material Company, Harbin Institute of Technology, and Hunan Agricultural University, and took 5 years to complete. The main technical principle is: the main body of the coating is combined with the fresh-keeping and anti-mildew additives to form an environmentally friendly coating. The coating process and the microcapsule granulation technology are used for the first time at home and abroad to apply the functional coating on the surface of the film and according to different food requirements Different adjustments are made so that ordinary films have the properties of fresh-keeping, mildew-proof and anti-fog.

Before the review, the technology has been applied in many enterprises and units such as Beijing Shounong Group, Beijing Vegetable Basket Project, Xiangtan Binzhilang Food Company, Hunan Taste King Group Company, Inner Mongolia Fengzhen Mooncake Association, Inner Mongolia Zhang Jintao Smoked Chicken Company, etc. It has the characteristics of good reproducibility and high degree of maturity, and has significant economic benefits. For example, for dried fruit foods, the barrier property of the packaging material is improved by 2 to 4 times compared to ordinary packaging materials , the preservation time is extended by 1 to 3 times, and the anti-fog effect is increased by 80% .

The expert review team led by academician Chen Kefu of the Chinese Academy of Engineering agreed that the freshness and mildewproof film has high technical content and strong innovation, and it has reached the international advanced level in general, and has good economic benefits.
