Russian cosmonauts are trialling a fastfood snack system designed to preserve freshness in wholesome Mediterranean products, even in the long-term room temperature storage required for six-month International Space Station missions.

The Mediet (Mediterranean Diet) experiment uses vacuum-sealed plastic packages of dried tomatoes, mature cheese, piadina bread, peaches and chocolate from Italy on an aluminium ergonomic tray. The food is subjected to high pressure processing (4000-6000 atu) technology, eliminating enzymes and bacteria without altering its nutrition, taste, texture and colour, enabling long-term room temperature storage.

The food is either pre-cut or viscous enough to remain intact in weightlessness, (for instance tomatoes in oil). Mediet has been developed by the International Space Centre for Space Applications.
