Horseradish Oil

Horseradish oil is a volatile oil extracted from the root of the horseradish plant (Armoracia rusticana). It contains compounds like allyl isothiocyanate, which give horseradish its characteristic pungent flavor and aroma. The oil is typically produced through steam distillation or solvent extraction.

Manufacturers add horseradish oil to provide a sharp, spicy flavor to foods. It is commonly found in condiments like horseradish sauce, mustard, and salad dressings, as well as in seasoning mixes, marinades, and some cheese products.

Horseradish oil is generally recognized as safe (GRAS) by the FDA for use as a flavoring agent. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated horseradish and its extracts, but did not set a numeric acceptable daily intake (ADI). While horseradish has been studied for potential health benefits, such as antimicrobial properties, these are generally associated with whole horseradish or its extracts, not specifically the isolated oil at typical food ingredient levels. More research is needed to fully understand the effects of concentrated horseradish oil.
