Yes — Thai red paste is ultra-processed.
The ingredient list is valid. The product is classified as ultra-processed (UPF) because it contains modified tapioca starch, which is an industrially processed additive. According to the provided rules, the presence of modified tapioca starch alone is sufficient to classify the product as UPF. Other ingredients like citric acid are basic additives and do not by themselves make a product UPF, but the modified starch does.
Other sauces, condiments & spreads Nomi has checked — these ones aren't ultra-processed.

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.
