Several factors affect the quality of food after drying. This can be classified as physical, chemical, or nutritional. Physical aspects include color, odor, texture, and bulk or flow properties. Chemical qualities are the preservation of vitamins and nutrients. High temperature and oxygen are usually the enemies of bioactive compounds. The drying process can affect the stability of valuable compounds in plant-based foods. Carotenoids, which are highly unsaturated and susceptible to oxidation, are also affected.
Freeze-drying is a three-step process, starting with the freezing and continuing in a vacuum chamber. Then, water crystals are sublimated directly from the solid to the gas phase, or sublimation. Finally, freeze-dried food is sealed with nitrogen to prevent oxygen from contaminating the food. The process began thousands of years ago when the Incas used stone platforms in the high Andes and allowed the produce to dehydrate in the harsh climate. These high altitudes allowed water-free food to remain a lighter and more durable form, while also preserving the original color and texture. News of kannada
