On November 1, 2021, the International Organization for Standardization (ISO) issued a revision to the definition of “protein fibre” in ISO2076. With this revision, the term “protein fibre” now includes not only naturally-derived protein, but synthetically-produced protein as well. Furthermore, the minimum protein content required for fibres to meet this definition has now been set at 80%.

This standardization marks the first international recognition of synthetic structural protein materials and will serve to increase global awareness and societal confidence in Brewed Protein™ materials going forward.
