Guar gum

What you need to know

Guar gum is a natural fibre from guar beans. It thickens sauces, soups and dairy products and stops them separating.

It is considered low concern and is also used as a source of dietary fibre. Very large amounts can cause bloating.

Regulators set no numerical limit on its use.
