Abstract:
This study proposed and tested a simple, yet highly effective, and fairly
accurate laser light scattering system for evaluation of emulsion’s
functionality of emulsifying agents and their blends.
The laser light scattering system is built up from low cost readily
available components, without serious compromise of the elegance and
powerfulness of laser light scattering technique.
The laser light scattering system was used in studying the functionality
of three Acacia gums, A. senegal, A. seyal and A. polyacantha and their
blends. The study reversed that the emulsifying power (P) of the gums studied
can be arranged in the following order:
A. polyacantha > A. seyal > A. senegal.
The relative emulsifying power taking A. senegal as reference is of the order
1.4: 1.3: 1.
The study established that A. polyacantha gum form the most stable
emulsions, while A. seyal form the least one among the three gums.
Blending of the emulsifying gums shown that a superior emulsifier can
results of blend A. polyacantha and A. seyal in proportion of 30% to 70%.
