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, grilled chicken and mayonnaise.

Flavour enhancers

Boost savoury taste so less of the underlying ingredient is needed. Found in the grilled chicken.

Colours

Preservatives

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

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 and grilled chicken.
