Dehydrated onions are fresh onions that have been processed to remove their moisture content while retaining their natural flavor, aroma, and nutritional value. This is typically achieved through air drying, sun drying, or freeze drying methods. The dehydration process increases shelf life, reduces weight and volume for cost-effective transport, and preserves the pungency and sweetness of onions without the need for refrigeration.
They are widely used in food processing industries, ready-to-eat meals, spice blends, soups, sauces, seasoning powders, fast-food chains, and catering services. Dehydrated onions are favored in international markets due to their long storage stability, ease of handling, and intense flavor.
No Refrigeration Required: Ideal for countries with limited cold storage facilities.
