Ever looked at the ingredients list of a food label and thought 'what is that'? Then read on...

We tend to read over these ingredients and additives and focus on the well-known ones, like sugar, sodium, water etc.

This quick guide to some of the common 'unknown' ingredients and additives should help take the mystery out of these substances used during food manufacturing:

Hydrolysed vegetable protein – this is a protein derived from a vegetable source, like maize, soy or wheat, which has been broken down into its building blocks (amino acids). It has a meaty flavour and is generally used as flavouring in savoury products.

Lecithin – this is a fatty substance found in food like soy beans, egg yolks and sunflower oil. It is used mainly as an emulsifier food additive and can mostly be found in chocolate, salad dressings and frozen desserts.

Guar gum – this is a polysaccharide (type of carbohydrate) extracted from the guar bean. Highly refined guar gum is used in food products as a thickener and stabiliser, especially in jelly gums, ice cream and salad dressings.
