Dehydration is a process that removes water from food using hot air to prohibit bacteria growth and enzyme action. It preserves vegetables by slowing spoilage, and makes the food lightweight, nutritious, and easy to store or use. Dehydrated onion in particular is a solution to avoid crying when chopping onions fresh. It has a long shelf life of 1-10 years depending on packaging and expands back to its original volume when rehydrated in water. India has a 500 crore rupee onion dehydration industry that supplies both domestic and international markets.
