Onion Salt

Onion salt is a seasoning blend made from dried, ground onions and salt. The dehydration process concentrates the onion's natural flavour compounds. It is typically produced by mixing dehydrated onion powder with salt, often with anti-caking agents added to ensure a free-flowing product.

Manufacturers add onion salt to provide a savoury, umami flavour profile and saltiness to food products. It is used in a wide variety of savoury foods, including snacks, seasonings, marinades, processed meats, and ready meals, offering a convenient way to impart onion flavour without using fresh onions.

Onion salt is a food ingredient, not a food additive, and is therefore not listed on the Register of Food Additive Authorisations. Its primary health implication relates to its salt content. The UK government advises that adults should consume no more than 6g of salt per day, as excessive salt intake can contribute to high blood pressure. While no specific regulatory body has set an Acceptable Daily Intake (ADI) for onion salt itself, the salt content is the main consideration for health.
