Yes — Worcester sauce is ultra-processed.
The product contains tamarind extract, which is an industrially processed extract and has been pre-identified as an ultra-processed (UPF) ingredient in the given rules. According to the instructions, any product containing tamarind extract must be classified as UPF. Other ingredients such as garlic powder, onion powder, and chilli powder are processed but not necessarily UPF under the provided criteria; however, the presence of tamarind extract alone is sufficient to classify the entire product as UPF.

Yes — Worcester sauce by Tesco is ultra-processed, so it counts as a UPF (ultra-processed food). The product contains tamarind extract, which is an industrially processed extract and has been pre-identified as an ultra-processed (UPF) ingredient in the given rules. According to the instructions, any product containing tamarind extract must be classified as UPF. Other ingredients such as garlic powder, onion powder, and chilli powder are processed but not necessarily UPF under the provided criteria; however, the presence of tamarind extract alone is sufficient to classify the entire product as UPF.
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.
