Celiac Safety Glossary
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces โ such as shared cutting boards, toasters, fryers, or utensils โ rendering otherwise safe food dangerous for people with celiac disease.
- Parts Per Million (ppm)
- Parts per million (ppm) is a unit of measurement used to quantify gluten concentration. Labeling laws in the US and Europe permit a maximum threshold of 20 ppm, while Australia requires no detectable gluten (0 ppm).
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
- Wheat starch
- Wheat starch is wheat flour that has had the gluten protein washed out. While some European gluten-free foods use codex-grade wheat starch (tested below 20 ppm), it can still trigger reactions in sensitive individuals.
- Brewer's yeast
- Brewer's yeast is a byproduct of beer brewing that is heavily contaminated with gluten from barley; it is a common hidden ingredient in savory snacks and seasonings.
