A reference sheet is available to use along with the gluten-free Catering List.

The reference sheet points out where gluten may be an ingredient in manufactured and processed foods. Some examples are listed below. Any ingredients containing gluten will be marked on the label.

• Sausages, burgers and processed meat where flour may be used as a binder.
• Cereals where the main ingredient may be gluten-free (eg corn flakes or rice cereals) but malt extract or malt flavourings, both based on barley, are used in the flavouring.
• Stock cubes, soy sauce, gravy, sauces and salad dressings where flour may be used as a thickener.
• Crisps and flavoured snacks or nuts where wheat starch may be used in the flavourings or to ‘stick’ the flavourings on.
• Sweets and chocolate bars where wheat flour or wheat starch is often used.
• Processed cheese, processed yoghurts and grated cheese where a gluten-based ingredient may be used to thicken or separate.
• Flours derived from gluten-free foods such as potato flour or rice flour may have cross-contamination problems.
• Squashes or cordials which may contain barley.
