What makes it ultra-processed

Cosmetic additives

Added to change how the food looks, feels or tastes, not to keep it safe. A hallmark of ultra-processed food.

  • E415 Xanthan gum Xanthan gum is a thickener made by fermenting sugar with the bacterium Xanthomonas campestris.
  • E422 Glycerol Glycerol is a sweet-tasting liquid used to keep products moist and soft.
  • E460 Cellulose A food additive used to dissolve, dilute, disperse or otherwise physically modify a food additive or nutrient without altering its function -and without exerting any technological effect itself- in order to facilitate its handling, application or use of the food additive or nutrient.
  • E461 Methyl cellulose Emulsifiers are substances which make it possible to form or maintain a homogenous mixture of two or more immiscible phases such as oil and water in a foodstuff.
  • E464 Hydroxypropyl methyl cellulose Emulsifiers are substances which make it possible to form or maintain a homogenous mixture of two or more immiscible phases such as oil and water in a foodstuff.
  • E466 Sodium carboxy methyl cellulose Carboxymethyl cellulose is a thickener made by chemically modifying cellulose from wood or cotton.

  • Flavouring Flavourings are concentrated aroma preparations that add or intensify a taste.
  • Humectant Humectants are substances which prevent foods from drying out by counteracting the effect of an atmosphere having a low degree of humidity, or promote the dissolution of a powder in an aqueous medium.
  • Thickener Thickeners, often gums or modified starches, make liquids more viscous so that a product feels richer than its ingredients alone would make it.
  • Modified starch Modified starch is starch altered physically, with enzymes or chemically, so that it thickens, gels or survives freezing and heating better than ordinary starch.

Substances rarely used in home kitchens

Refined or extracted in factories, such as syrups made from starch or isolated proteins. The other hallmark of ultra-processed food.

  • Invert sugar Invert sugar is ordinary sugar split into glucose and fructose with acid or enzymes.
  • Vegetable fiber Isolated plant fibres, such as inulin, oat fibre or bamboo fibre, are extracted industrially and added to change texture or support "source of fibre" claims.
4 ingredients that would only make it processed

Kitchen staples like sugar, salt and oil. On their own they make a food processed, not ultra-processed.

  • Preservative Preservatives slow spoilage by microbes.
  • Salt Salt, added for taste and preservation.
  • Starch Starch extracted from cereals or potatoes, used to thicken.
  • Vegetable oil Vegetable oils are pressed or extracted from seeds, nuts and fruits.
