Ultra-processed food: what is really in it

Processing and additives: Subway US Roast Beef 6 Inch Sub

Reading the ingredient list closely, it contains corn syrups and invert sugar, dextrose, maltodextrin, emulsifiers, flavourings, preservatives, emulsifying and buffering salts and protein and dairy fractions.

Sweeten and control texture more cheaply than sugar alone. Found in the roast beef.

Dextrose

A simple sugar used for browning, bulk and mild sweetness. Found in the roast beef.

Maltodextrin

Bulks out a product and carries flavour, with little taste of its own. Found in the roast beef.

Emulsifiers

Help oil-based and water-based ingredients blend and stay blended. Found in the Artisan Italian bread.

Flavourings

Add or restore taste lost during processing. Found in the Artisan Italian bread, roast beef and mayonnaise.

Preservatives

Slow the growth of bacteria, yeasts and moulds in centrally prepared components, and keep cured meats pink. Found in the mayonnaise.

Emulsifying and buffering salts

Let processed cheese melt smoothly, keep cured meats moist, or hold acidity steady. Found in the roast beef.

Protein and dairy fractions

Isolated proteins and dairy by-products used to add bulk, structure or a creamy texture. Found in the Artisan Italian bread.
