Spirit of Summer Iced Tea - Spanish Peach

What it is. An intense sweetener made from sugar, around 600 times sweeter, so it is used in very small amounts.

Why it is used. Sweetens diet drinks, tabletop sweeteners, dairy and baked goods.

What the evidence says. Regulators have treated it as safe for decades and the acceptable daily intake has not changed. Newer laboratory work on a breakdown product, and the general question of sweeteners and the gut microbiome, keep it under discussion, but that work is early and has not moved any official position.

Permitted with an acceptable daily intake in all three regions.

What it is. Vitamin C, added to protect colour and flavour and sometimes to fortify.

Why it is used. Stops browning in juices and cut fruit, protects fats, and boosts vitamin content.

What the evidence says. Beneficial and harmless at the levels used. Included here as a reminder that an E number is just a code, and plenty of them are ordinary nutrients.

Permitted freely, no concern.

What it is. A mild acid found naturally in citrus fruit, made commercially by fermentation.

Why it is used. Adds tartness, balances flavour and helps preserve. One of the most used additives in food.

What the evidence says. Safe at food levels. No credible health concern for the additive itself.

Permitted freely.

What it is. A fibre made by fermenting sugars with a bacterium, which thickens liquids at very low doses.

Why it is used. Thickens sauces and dressings and gives structure to gluten free baking.

What the evidence says. Passes through largely undigested and is treated as safe by regulators, with no numerical intake limit. Very large amounts act as fibre does, which is a digestive effect rather than a safety one.

Permitted freely.
