Purity Protocol

What is Purity Protocol?

Purity Protocol is a Start Clean, Stay Clean, farm-to-plate method of ensuring oats are gluten-free. It was developed by pedigreed seed growers to provide people who have celiac disease, gluten-intolerance or wheat allergies with clean, safe gluten-free oat ingredients.

Why is Purity Protocol Needed?

    Though oats are naturally gluten-free, they can be contaminated with gluten-containing grains, such as wheat, rye, barley and triticale and grain dust. The shape and color of oat kernels makes it especially difficult to clean out these impurities.

    The Faces of Avena Purity Protocol

    The success of Avena Purity Protocol relies on the collaboration, contributions and accountability of each member of the supply chain. Since 2008, Avena Purity Protocol has developed as an integrated approach to preventing contamination throughout the entire supply chain. This multi-layered strategy is grounded in the knowledge that no single control step is adequate to control gluten-contamination. Rather, success lies in multiple controls, both physical and chemical.

    How does it work?

    Purity Protocols start with seed selection and incorporate a system of checks and balances from the field, to delivery and milling. This allows oats to remain gluten-free. Partnerships with farmers are key to these protocols, as are seed stock purity and criteria for growing, harvesting, transporting, storing and   processing oats.

    The minimum requirements for Purity protocol are set out in the article Definition of the “Purity Protocol” for Producing Gluten-Free Oats* published in Cereal Chemistry, January, 2017. This definition does not go as far as incorporating gluten-testing protocols throughout the system or of final product.

    Avena Purity Protocol Moves Beyond the Minimum Requirements of Purity Protocol

    • Sampling size and frequency of testing protocols are rigorous.
    • Each load delivered to Avena by farmers is sampled and tested for purity and cleanliness, to rule out contamination with gluten.
    • Additional testing parameters include milling quality, size and moisture.
    • Every tote of each lot of final product is tested, with a lot being a day’s production.
    • We use the R5-ELISA method for gluten-testing, the industry gold standard.
    • We operate a dedicated gluten-free facility which incorporates state-of-the-art pasteurizing equipment – providing a validated kill step for ingredients that are RTE.
    • We ensure that oats are free of all labeled allergens, heavy metals, pesticide residues, glyphosate and mycotoxins.
    • We include grower updates and training, customer and farmer networking events, and contracts that include an Avena Purity Protocol premium.
