Ultra-processed food: what is really in it

Processing and additives: Starbucks US Butter Croissant

Reading the ingredient list closely, it contains thickeners and gums, flavourings, preservatives and protein isolates. These are not there to add nutritional value. They make industrial production and distribution possible.

Thickeners and gums

Thicken and stabilise fillings, sauces and egg mixtures so they hold up through freezing, storage and reheating. Found in the dough conditioner.

Flavourings

Add or restore taste lost during processing. Found in the butter.

Preservatives

Slow the growth of bacteria, yeasts and moulds, or stop fats going stale, in centrally prepared food. Found in the enriched wheat flour and dough conditioner.

Protein isolates

Concentrated proteins extracted industrially to raise the protein count or build texture. Found in the dough conditioner.
