Active packaging in the food industry involves using special materials that interact with the air inside food packages to keep the food fresh for longer. By adding or removing gases, these technologies help prevent food from spoiling due to factors like moisture, oxygen, and microbes. Antimicrobial packaging is key to stopping harmful bacteria from growing on food. By incorporating different active components, like nanotechnology, food quality can be preserved. Combining active packaging with intelligent packaging is effective in maintaining food quality. Overall, active packaging helps extend the shelf life of food, but it also has its pros and cons compared to other packaging methods.
