Kinetic and Thermodynamic Study of Extraction of Oleoresin Containing Curcuminoids from Turmeric (Curcuma Longa L.)

Numerous studies are nowadays undertaken across the world laboratories on turmeric and show its excellent virtues in various fields such as medicine, pharmacology, cosmetics, so forth. In this paper, to enlarge domain of scientific knowledge, a kinetic thermodynamic behavior curcuminoid extraction from Curcuma longa L has been investigated dilute medium using ethanol solvent under magnetic stirrer. Through KUNYIMA method, by means first law, global constant calculated at 250 rounds per minute (rpm) data have shown Constance 500 same temperature (27.5 °C). The can serve build commercial tank production curcuminoids sizing factor endow Democratic Republic Congo with home technology is hereby discussed. Extraction enthalpy entropy closed system Arrhenius relation. results indicate that an endothermic phenomenon. This stirrer probably suggests predominance enol form curcumin presence tautomeric ketone form. Also, phenomenon last non-bioavailability. energy promoting solubilization arises solvent, stirrer, meet alike hydroxyl group (like dissolves like). value variation evidently suggested disturbance natural order after extraction. Note KUNYIMA's second law announced.
