Sriracha: what the available label data says

Many popular brands of Sriracha contain soy. The most common soy ingredient is soy sauce, which is a primary flavoring agent. Some brands may also use soybean oil. It is essential to check the ingredient label of the specific product as formulations can vary.

Several brands offer Sriracha-style sauces that are soy-free. Look for products that explicitly state they are soy-free or check ingredient lists carefully. Some brands like Kikkoman (check specific product lines as some contain soy sauce) or Huy Fong (the most common brand, which *does* contain soy) have soy-free alternatives. Other brands like Yellowbird and Cholula (check labels, as some varieties may contain allergens) often have soy-free options. Always verify the ingredients.

It is generally not safe to consume most common Sriracha brands if you have a soy allergy due to the frequent presence of soy sauce or soybean oil. While some soy-free versions exist, you must meticulously check the ingredient list of every bottle to ensure it does not contain soy or derivatives. If in doubt, it is best to avoid it.

When ordering food that includes Sriracha or a similar hot sauce, ask the server or vendor: 'Does this sauce contain soy sauce or soybean oil?' and 'Is there a risk of cross-contamination with soy products in your kitchen?' Be specific about the allergy and the ingredients you need to avoid.
