Study on the influence of automatic packaging film for frozen food on the preservation effect of frozen food
Publish Time: 2025-02-04
With the acceleration of the pace of modern life, frozen food is favored by consumers for its convenience and long shelf life. However, how to maintain the freshness and quality of food during the freezing process has always been an important challenge facing the food industry. As an innovative technology, automatic packaging film for frozen food provides an effective solution for the preservation of frozen food.The main function of automatic packaging film for frozen food is that it can effectively block the invasion of external air, moisture and microorganisms, thereby delaying the oxidation and deterioration of food. In the frozen state, the moisture in the food will form ice crystals, and the size and distribution of these ice crystals have a direct impact on the taste and quality of the food. Automatic packaging film for frozen food helps to maintain the cell structure of food and reduce water loss during thawing by reducing the formation and growth of ice crystals, thereby maintaining the fresh taste of food.In addition, automatic packaging film for frozen food also has a good atmosphere preservation function. By adjusting the gas composition in the packaging film, such as increasing the concentration of carbon dioxide and reducing the concentration of oxygen, the growth and reproduction of microorganisms can be inhibited, further extending the shelf life of frozen food. This controlled atmosphere preservation technology is not only suitable for high-protein foods such as meat and seafood, but also for foods rich in water such as fruits and vegetables.Studies have shown that the color, taste, nutritional value and flavor of frozen foods using automatic packaging film for frozen food can be better maintained during storage. Compared with traditional frozen packaging, automatic packaging film for frozen food can significantly reduce the oxidation and deterioration of food, extend the shelf life of food, and maintain the freshness and quality of food.In summary, automatic packaging film for frozen food has a significant impact on the preservation effect of frozen food. It can not only effectively block external factors and reduce the formation of ice crystals, but also inhibit the growth of microorganisms through controlled atmosphere preservation technology, thereby maintaining the freshness and quality of food. With the continuous development of the food industry and the improvement of consumers' requirements for food quality, automatic packaging film for frozen food will become one of the important technologies for the preservation of frozen food in the future.
