Yes — Walkers Salt & Vinegar crisps 6 Pack - OUTER PACKAGING ONLY is ultra-processed.
Classified as ultra-processed because the ingredient list includes industrial flavouring additives (listed simply as “flavouring”) in the salt & vinegar seasoning. Such added flavourings are industrial formulations used to modify taste and are a key marker of ultra-processed foods in the NOVA system, even though the base ingredients (potatoes, oils, salt, vinegar, citric acid) are otherwise minimally processed or basic culinary ingredients.
