Dehydrated red onions are a popular food ingredient that has undergone a drying process to remove their moisture content, resulting in a concentrated and shelf-stable product. These onions are derived from fresh red onions that have been sliced or diced and then subjected to controlled dehydration methods such as air drying, freeze drying, or sun drying. The process preserves the flavor, color, and nutritional value of the onions while extending their shelf life.
