Nuts are chemically volatile. Their high unsaturated fat content makes them a prime target for rapid oxidation, leading to the dreaded "rancid" flavor profile. Standard vacuum sealing solves the oxygen problem but creates a physical crushing hazard for fragile kernels like walnuts and cashews. This engineering report analyzes the dual-function solution: Vacuum-Gas-Seal technology. We explore how replacing oxygen with inert nitrogen creates a "gas cushion" that safeguards both the chemical integrity and the physical structure of premium nuts.
