Description
Vacuum sealing removes the majority of atmospheric oxygen, dramatically reducing aerobic microbial growth and oxidative rancidity to extend shelf life.
Technical
By evacuating air, the process suppresses aerobic respiration and limits the availability of oxygen for lipid oxidation, thereby reducing the formation of peroxides, aldehydes, and ketones that cause rancidity. The reduced oxygen environment also slows enzymatic reactions that degrade proteins and carbohydrates, preserving texture and flavor over extended periods.
