Are frozen chips ultra-processed?

Plain chips are group 3. Coated ones are not.

Plain frozen chips are group 3, and often nothing more than potatoes and sunflower oil. Freezing adds nothing, and cutting a potato removes rather than adds.

Coated is the word to look for

Anything described as crispy, extra crispy or coated carries a batter, and that batter is where the additives are: modified starch, raising agents, stabilisers, colours such as dextrose for browning, and often flavourings. That is group 4.

  • Potatoes, oil, and possibly salt: group 3.
  • Coated, crispy, or steak-cut with a stated coating: group 4.
  • Seasoned wedges and fries: group 4, from the seasoning.
  • Croquettes, hash browns and waffles are reformed potato and are group 4.

The same split runs through crisps: a sliced potato with oil and salt is group 3, and anything reconstituted from potato flakes is group 4 by construction.

Working this out from a receipt is harder than from a packet, because a till prints about twenty characters of product name and no ingredients list. That is the problem Bagged exists to solve, and how a receipt is structured explains why it is the hard part.
