Modified atmosphere packaging film is a special packaging material. Its main function is to inhibit the oxidation of food and the growth of microorganisms by adjusting the gas composition inside the packaging, thereby extending the shelf life of food. This film allows the permeation of specific gases while blocking the entry of other gases, creating an ideal fresh-keeping environment for food.
Food packaged with modified atmosphere packaging film can maintain a good appearance, texture, color and smell during storage. This is because modified atmosphere packaging film can effectively reduce the contact between food and oxygen, thereby reducing the oxidation rate of food and maintaining the freshness of food.
Modified atmosphere packaging film inhibits the growth and reproduction of microorganisms by adjusting the gas composition inside the packaging, such as increasing the ratio of carbon dioxide and nitrogen and reducing the oxygen content. This environment can slow down the spoilage process of food and further extend the shelf life of food.
Experimental data show that compared with traditional packaging, the number of microorganisms in food packaged with modified atmosphere packaging film remains stable during storage, effectively inhibiting the deterioration of food. At the same time, the samples in the modified atmosphere packaging group also maintain good quality indicators such as color, texture, and taste.
Modified atmosphere packaging film is widely used in the packaging of raw and cooked meat, fish, fresh fruits and vegetables, baked goods, convenience foods, dairy products and other products. For different types of food, modified atmosphere packaging film can adjust the gas composition inside the packaging according to the characteristics and needs of the food to achieve the best preservation effect.
Due to the significant effect of modified atmosphere packaging film in extending the shelf life of food, its market growth rate has been steadily increasing. As consumers' requirements for food quality and freshness continue to increase, the application prospects of modified atmosphere packaging film will be broader.
Modified atmosphere packaging film effectively inhibits the oxidation of food and the growth of microorganisms by adjusting the gas composition inside the packaging, thereby significantly extending the shelf life of food. This packaging material is of great significance in improving food quality and reducing food waste.
