Food preservation card is also known as alcohol pack and externally controlled food preservative. When used, it can form a certain concentration of gas-phase protective layer around the food to be preserved, and the freshness retainer is not affected by the PH value of the food to be preserved. It can inhibit the growth of various molds, bacteria and spoilage bacteria, so as to have a good fresh-keeping effect.
Through the slow release of the fresh-keeping gas, a certain concentration of gas-phase protective layer is formed around the food in the package, which can inhibit a variety of molds, bacteria and other spoilage bacteria, and at the same time combine with the free water in the food to reduce its water activity (affecting the shelf life of food) an important factor), so as to achieve the purpose of preservation.
Both externally controlled preservatives and food deoxidizers can be used in moon cakes and pastries to preserve freshness, but externally controlled preservatives cannot be used in the preservation of nuts and roasted seeds and nuts. The principles of the two are completely different. Food deoxidizers are mainly used to absorb oxygen in food packaging, so that food can be stored in an anaerobic state, mainly to prevent food oxidation. It is especially suitable for the preservation of nuts, roasted seeds and nuts, meat and pastries, such as peanuts, melon seeds, pistachios, ham, moon cakes, bread and the like. However, externally controlled preservatives cannot be used in roasted nuts because it does not have the function of preventing food oxidation.
