Abstract

The use of flavoring compounds in the food industry is now increasing day by day. The aim of the present study was to crystallization and cross-linking of lipase from Pseudomonas Cepacia and to study the kinetics of the synthesis of a rose flavor ester, 2-phenethyl acetate in an organic solvent system. The effect of different reaction co-ordinates such as enzyme concentration, temperature, substrate concentration were studied and found the maximum conversion in 50mg/ml enzyme concentration, temperature at 550C and substrate ratio of 1:4. The stability of the cross-linked lipase was observed in comparison to free lipase and retained 50% of original activity by cross linked lipase up to seven days of incubation.
