Amino Acids

FERMOPURE® – plant-based L-cystine and L-cysteine

Traditionally, the amino acid L-cysteine and its dimer L-cystine have been obtained from animal-based starting materials, such as hair or feathers. WACKER is the first company in the world to produce plant-based L-cystine in a sustainable fermentation process. This patented technique was awarded an environmental prize in 2008, because it uses 96% less hydrochloric acid than is required for the typical chemical extraction from hair and feathers. WACKER’s natural L-cystine and vegan L-cysteine are manufactured with state-of-the-art equipment, resulting in the highest quality. Since 2019 the products are marketed under the trade name FERMOPURE®.

In 2018, production was transferred to the Spanish site Leòn. Here WACKER produces L-cystine in compliance with ISO 9001:2015 and the outstanding quality demands of FSSC 22000, a GFSI-recognized (Global Food Safety Initiative) standard for food safety management systems. WACKER’s fermentation site in León has certificates for both standards to guarantee a superior safety level for our products.
