1. Application of CO2 in food packaging
China has successfully studied the use of nanotechnology to efficiently catalyze CO2 to form degradable plastics. That is, the catalyst used to make plastic from CO2 "destroys" to the nanometer level, completes the polymerization of catalytic molecules and CO2, and catalyzes about 130 grams of CO2 per gram of catalyst, forming a new packaging material containing 42% CO2. As an environmentally friendly material with excellent degradability, it has a wide range of applications.
2. Application of nitrogen in food packaging
Nitrogen (N2) is an ideal inert gas, which has special effects in food packaging: it does not react with food and is not absorbed by food, it can reduce the oxygen content in the packaging, and it can greatly increase the growth and reproduction of microorganisms such as bacteria and mold , Slow down the oxidative decay and decay of food, thereby keeping food fresh. Nitrogen-filled packaged foods can also well prevent the food from kneading and breaking, sticking or shrinking the food, and adhere to the food's shape, dryness, crispness, color, and flavor. Now nitrogen-filled packaging is rapidly replacing traditional vacuum packaging, and has been applied to fried potato chips and chips, oil-cooked food, etc. Popular with consumers, especially children and young people, nitrogen-filled packaging is expected to be used in more food packaging.
