ABSTRACT:
The main objective of the present work was to study the effect of surfactant on extraction of caffeine from coffee powder using surfactant sodium lauryl sulfate. The extraction was carried out at various conditions such as time of extraction, temperature, sonication. The time period employed is at intervals of 30min, 60min, 120min and the temperature exposure was at various degrees like 0o c, 40oc, 80oc .The final sonication step was at various sonication times of 2min, 5min, 0min and 15min. The evaluation of the resulting product was done by measuring various parameters like density, specific gravity, viscosity, surface tension, colorimetric estimation, pH. Among all these conditions, sonication process along with sodium lauryl sulfate can be considered as favourable method for extraction of active constituents from the crude drug powder and this technique can be extended for study of other extraction of crude drug powders.
