Free sugar vs total sugar

Where the sugar comes from: Leon Aji Verde Crispy Chicken Burger

Portion	Total sugar	Free (added) sugar	Naturally occurring	Free sugar in teaspoons
Per portion	5.9g	3.5g	2.4g	0.9 tsp

Boone estimates that 3.5g of the 5.9g total sugar is free sugar, from the syrups, added sugar and fruit juice in the ingredient list. The remaining 2.4g is naturally present in milk and dairy, vegetables and pulses and grains. LEON publishes total sugar only, so this split is Boone's estimate.

NHS daily free sugar limits: 30g for adults and children 11+, 24g age 7 to 10, 19g age 4 to 6. Sugars naturally present in milk and whole fruit are excluded. Sugars in fruit juice, purées, syrups and plant drinks made from hydrolysed grains count as free sugar.

Protein isolates and concentrates

Proteins extracted from plants to add bulk, bind or replace egg and meat.

Baking improvers

Speed up industrial bread making and keep bread soft for longer.

Added fibres

Isolated fibres added for texture, bulk or a fibre claim.
