The efficiency of complex coacervation of gelatin A with sodium carboxymethyl cellulose
(SCMC) was measured by checking viscosity, coacervate yield (%), and turbidity of the
mixture. Maximum coacervation occurred at pH 3.5 and SCMC: gelatin ratio of 1.0:
2.33. Encapsulation efficiency, oil content, oil load, and release behavior of the micro-capsules were studied. The size and nature of the microcapsules varied with the con-centration of polymer and NSO as revealed by scanning electron microscopy study.
Fourier transform infrared (FTIR) spectroscopy indicated that there was no significant
interaction between the polymer and NSO.
