Yes — Potato Rosti by Waitrose is ultra-processed, so it counts as a UPF (ultra-processed food). Classified as ultra-processed because it contains dextrose monohydrate, an industrially refined sugar ingredient characteristic of UPFs.
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.
