Modeling And Optimization Of Solvent-Free Isoamyl Acetate Production Via Enzymatic Esterification

Isoamyl acetate is an organic compound listed under the esterfamily, and used as flavor additive especially in food industries. Studies on esterification processes begin with traditional extraction of ester from plants,followed by chemical synthesis route. Nowadays, the esterification process has...
