Ultra-processed food: what is really in it

Processing and additives: Burger King US Bacon and Swiss Flame-Grilled Chicken Sandwich

Burger King US Bacon and Swiss Flame-Grilled Chicken Sandwich is assembled from 7 separately manufactured components, combined and served at the point of sale. Reading the ingredient list closely, it contains dextrose, maltodextrin, modified starches, emulsifiers, thickeners and gums, flavourings, flavour enhancers, colours, preservatives, emulsifying and buffering salts and protein and dairy fractions. These are not there to add nutritional value. They make industrial production and distribution possible.

Dextrose

A simple sugar used for browning, bulk and mild sweetness. Found in the potato bun and chicken breast.

Maltodextrin

Bulks out a product and carries flavour, with little taste of its own. Found in the potato bun, chicken breast and royal sauce.

Modified starches

Starches altered industrially to thicken, bind or hold texture through freezing and reheating. Found in the chicken breast.

Emulsifiers

Help oil-based and water-based ingredients blend and stay blended. Found in the processed swiss cheese.

Thickeners and gums

Thicken sauces, fillings and drinks and stop them separating. Found in the chicken breast and royal sauce.

Flavourings

Add or restore taste lost during processing. Found in the potato bun, chicken breast and royal sauce.

Flavour enhancers

Boost savoury taste so less of the underlying ingredient is needed. Found in the royal sauce.

Colours

Restore or standardise appearance after processing. Found in the potato bun and royal sauce.

Preservatives

Slow the growth of bacteria, yeasts and moulds in centrally prepared components. Found in the potato bun, royal sauce, processed swiss cheese and bacon.

Emulsifying and buffering salts

Let processed cheese and cream melt smoothly, or hold the acidity of drinks steady. Found in the chicken breast, processed swiss cheese and bacon.

Protein and dairy fractions

Isolated proteins and dairy by-products used to add bulk, structure or a creamy texture. Found in the potato bun and royal sauce.

Boone counts every distinct named ingredient on Burger King’s published component lists, including sub-ingredients, and removes duplicates, so salt appearing in four components counts once. Additive class names are dropped and the named substance kept, so “leavening (baking soda)” counts baking soda once. Ice and water added at the counter are not counted. Raw covers whole foods and basic kitchen staples such as flour, sugar, salt and oil. Manufactured covers substances that only exist as an output of industrial processing. Every figure here is a minimum. The build uses a BBQ sauce.
