WebSep 1, 2024 · Although mainly used as a solvent, ethyl lactate is also used as a food additive and flavour chemical [ 1, 2]. It is produced by the esterification of lactic acid (LA) with ethanol (EtOH), which is a reversible reaction with water as a co-product. Although esterification reactions are self-catalysed by the acid involved in the reaction ... WebEthanol fermentation is a two step process. Pyruvate (pyruvic acid) is first converted into carbon dioxide and acetaldehyde. The second step, converts acetaldehyde to ethanol and oxidizes NADH to NAD+. Attribution: Marc T.
