For example In our daily lives, staple grains like rice are typically packaged using vacuum-sealed food bags. Vacuum packaging helps reduce the oxygen concentration in the storage environment, thereby slowing down the respiration rate of the rice and inhibiting mold growth. This process effectively prevents the rice from spoiling, becoming moldy, or being infested with pests, ensuring that its quality is preserved even better over time.
