Origin of dehydrated vegetables
Dehydrated vegetables, which look like ordinary products, have a very honorable origin:
In the "Apollo" aviation program, NASA has invented frozen dehydrated vegetable technology to solve the problem that astronauts can eat vegetables to supplement vitamins in space. The technology is to remove too much water contained in the vegetables, and the chlorophyll and vitamins contained in the fresh vegetables can still be preserved, which is convenient for storage, storage and transportation. The cold dehydration treatment removes almost all of the water in the food and reduces its weight by 20% while retaining 98% of the nutrients in the food.
