Description
Freeze-dried instant coffee granules. The freeze- drying process preserves food by rapid freezing, followed by complete dehydration to remove all moisture. It is then packaged to seal out water and oxygen. If moisture gets in microbes in the food grow and multiply causing decay, and if oxygen enters fat becomes rancid. The technique was first used in the 1950s to provide lightweight ration packs for astronauts, explorers and the armed services.
