Yes — Horseradish Sauce is ultra-processed, so it counts as a UPF (ultra-processed food). Classified as ultra-processed because it contains the additive potassium sorbate (a preservative) and added food acids (acetic acid beyond what is naturally present in spirit vinegar, and citric acid) which are industrial additives used to extend shelf life and control acidity.
Nomi flags one ingredient in Horseradish Sauce as an ultra-processed marker: potassium sorbate. See the full ingredient breakdown above for what each one is.
Ultra-processed foods (UPFs) are industrial formulations made with ingredients and additives you wouldn't find in a home kitchen — such as emulsifiers, artificial flavourings, colourings and modified starches. The classification is based on the NOVA system used by researchers and dietitians worldwide.
