What is the space application for a freeze dried food invention?
The invention of freeze dried food for use in space flights solves many of the problems associated with bringing normal food on such a mission, including space constraints and the risk of food spoilage during protracted trips.OriginsThe lack of gravity in space makes normal eating and drinking impossible; to prevent foods and liquids from floating around freely within the spacecraft, causing potential technical problems, freeze-drying is utilized.EvolutionIn the early days of space exploration, powders, cubed foods and squeezable tubes were the norm. As the years passed, these offerings gave way to improved food quality and menu diversity, and freeze-dried foods became easier to reconstitute and reheat, while such items as tubed meals disappeared altogether.TypesThanks to the freeze-drying process, astronauts today enjoy a wide variety of food options including shrimp cocktail, butterscotch pudding and ice cream. Meals are designed to meet the Recommended Dietary Allowances for calorie
