About
Onion-garlic dehydrated powder is a blend of powders obtained by drying Allium cepa (onion) and Allium sativum (garlic) bulbs without bleaching or precooking, removing moisture under controlled conditions to yield a free-flowing, shelf-stable powder. It is widely used as a natural flavouring, seasoning, and functional food ingredient in processed foods, soups, sauces, snacks, and spice blends.
Safety summary
Both dehydrated onion and garlic powders are broadly recognised as safe for the general adult population, with no established ADI and no IARC carcinogenicity classification; they are regulated as spices/natural flavourings under FDA 21 CFR 182 (GRAS) and FSSAI FSS Regulations 2010. High-dose supplemental use may cause gastrointestinal irritation (heartburn, bloating), and garlic's organosulfur compounds can potentiate antiplatelet/anticoagulant effects at high doses. Salmonella contamination is a documented microbiological hazard for dehydrated forms requiring good manufacturing practices.
