Yes — Kee Sweet Soy Sauce by Lee Kum Kee is ultra-processed, so it counts as a UPF (ultra-processed food). Classified as ultra-processed because the ingredient list contains industrial additives and refined ingredients including flavour enhancers (E621 monosodium glutamate, E631 disodium inosinate, E627 disodium guanylate), colour E150a (caramel colour), and glucose-fructose syrup, all of which fall under NOVA ultra-processed food criteria.
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.
