Performance comparison of downstream unit operations and process chains for the purification of amino acids for food, feed and pharma applications

This is the authors' abstract. We don't add key points for this paper.

Highlight • Amino acids are increasingly relevant in food, feed and pharma applications.• Amino acid feeds have shifted from biomass hydrolysates to fermentation broth.• Chromatography is a versatile purification method for most amino acids.• Membrane-based processes and crystallization can outperform chromatography.
