Method and system for preserving food

This method extends the shelf-life of food and reduces harmful microbes by exposing it to microwave radiation. Food is treated with at least two pulses from both horizontal and vertical microwave sources for a minimum of seven seconds, then sealed in a container.

Why it matters: Since 2008, solid-state microwave generators have become more precise and energy-efficient, enabling better control over the specific pulsing and wavelength requirements for this food treatment method. This could make industrial application more viable and cost-effective.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMicrowave generators, precise controls, dual-axis system
