ISO/DIS 25134:2026

This Standard applies to protein products intended for human consumption that are not derived from animal sources. It covers proteins obtained from plants (including vegetables and algae), fungi and micro-organisms such as bacteria, yeasts and moulds. It covers three types of protein product : - protein flour, - protein concentrate, - protein isolate. This document does not apply to : - wheat gluten [1] and soya proteins [2] that are defined by CODEX, - precision fermentation proteins (e.g specific proteins intentionally obtained from recombinant DNA technology) and proteins of animal origin, irrespective of the production method employed. Example : casein produced from non-animal sources, such as plants, falls outside the scope of this standard, - raw materials (source materials) used to produce these proteins, as well as the compound foods that use these protein products as ingredients, - labelling and/or claims for foods sold to consumers.
