Abstract:

The use of biopolymers for bioactive encapsulation continues to be an area of research interest. In this study gum arabic and serum albumin was used for encapsulation of poorly water-soluble curcumin by coacervation method. To find a new procedure and set an emulsification-coacervation method, several experiments has been carried out by varying different parameters including pH (3.7- 4) and albumin to gum Arabic weight ratios (2:1, 1:1). Complex coacervation between gum arabic and serum albumin is restricted to a narrow pH range where both molecules carry maximum opposite charges. Optimum conditions for appropriate coacervation were found in albumin to gum arabic ratio of 2:1 because of better texture based on Scanning Electron Microscopy(SEM). SEM micrographs revealed a sponge-like coacervate phase and sheet-like structure. The SEM image showed particle size was in the range of 40-50 μm. Encapsulation efficiency was found to be around 90%. DSC was used to to predict the thermal behaviour of the particles.This study showed that the emulsification-coacervation method is an efficient and promising technique for curcumin encapsulation
