LUBBOCK, TEXAS (RFD NEWS) — Longer space missions could create new demand for safer, better-tasting shelf-stable foods, and Texas A&M AgriLife researchers say electron beam technology may help modernize the process.
Suresh Pillai with Texas A&M AgriLife Research says electron beam, or eBeam, processing could replace some thermal stabilization methods now used for space food. Current heat-based processing helps ensure food safety, but it can change flavor, texture, and appearance.
Electron beam processing uses ionizing energy instead of heat to reduce harmful microorganisms. Pillai says the process can also run continuously, which could help produce larger volumes of food as commercial spaceflight and long-duration missions expand.
The research has a food quality and security angle. Pillai says older radiation standards date back to the 1960s, while newer science may allow lower doses that preserve quality. Electron beam systems also avoid some concerns tied to cobalt-60 sources.
The work could apply to ready-to-eat meals and delicate foods such as freeze-dried berries.
