Ultra-processed food: what is really in it

Processing and additives: Burger King US Impossible Whopper

Burger King US Impossible Whopper is assembled from 8 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, preservatives, phosphates and raising agents, firming agents 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 sesame seed bun and impossible™ whopper patty.

Maltodextrin

Bulks out a product and carries flavour, with little taste of its own. Found in the sesame seed bun.

Modified starches

Starches altered industrially to thicken, bind or hold texture through freezing and reheating. Found in the impossible™ whopper patty.

Emulsifiers

Help oil-based and water-based ingredients blend and stay blended. Found in the sesame seed bun.

Thickeners and gums

Thicken sauces, fillings and drinks and stop them separating. Found in the sesame seed bun, impossible™ whopper patty and pickles.

Flavourings

Add or restore taste lost during processing. Found in the impossible™ whopper patty, ketchup and pickles.

Flavour enhancers

Boost savoury taste so less of the underlying ingredient is needed. Found in the impossible™ whopper patty.

Preservatives

Slow the growth of bacteria, yeasts and moulds in centrally prepared components. Found in the impossible™ whopper patty.

Phosphates and raising agents

Hold moisture in meat, control acidity or make batters and doughs rise. Found in the sesame seed bun.

Firming agents

Keep processed vegetables and fruit pieces firm after packing. Found in the pickles.

Protein and dairy fractions

Isolated proteins and dairy by-products used to add bulk, structure or a creamy texture. Found in the sesame seed bun and impossible™ whopper patty.

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.
