No — Proper corn sea salt by Proper is not ultra-processed, so it is not a UPF (ultra-processed food). Ingredients are wholegrain corn, rapeseed oil, and sea salt. These are basic culinary ingredients with no industrial additives, flavorings, or refined syrups, so the product is not classified as ultra-processed under NOVA.
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.
