Food preservation process

This invention describes a process to preserve various foods for up to five years without needing refrigeration or added preservatives, while keeping their natural taste and texture. The process involves packing food into an open container, filling 70% to 95% of its volume, then heating it to a specific temperature (50-85°C) for a short time (15-25 minutes) while still exposed to air. After this, the air inside the package is replaced with a different gas mixture, the package is sealed, and then it undergoes a final heat treatment.

Why it matters: Since 2009, advancements in packaging material science have improved gas barrier properties, and industrial process control systems have become more precise for managing temperature profiles and gas compositions.

Status: ExpiredProtection ended and was never renewed
How hard to build: ModerateHeating, gas flushing, sealing, and thermal treatment equipment
