Dried diced onion is produced in Vietnam from fresh onions (allium cepa), dehydrated to preserve natural nutrients, dietary fiber, and functional compounds such as oligosaccharides. Onions are known to support gut health through beneficial microflora activity and provide minerals and vitamins including b-complex and vitamin c. The product offers long shelf life, easy storage, and consistent quality, making it suitable for food processing, seasoning applications, ready-to-cook foods, and export-oriented B2B sourcing.
