| Abstract | Curcuminoids from turmeric (Curcuma longa) provide the powerful bioactive activities, such as anti-inflammatory, antibacterial, antidepressant, antitumor and gastro protective properties. The objective of this research was to investigate the effect of optimize microwave-assisted extraction (MAE) on curcuminoidfrom turmeric. The experiments were conducted using varying microwave powerranging from 400 to 800 watt and extraction times of1, 2, 3, 4 and 5 minutes using 2?5 factorial experiment.The microwave power and extraction time were affected on extract yield, total phenolic content, antioxidant activity (EC50) and curcuminoids content. The extractionusing the microwave power of800 watt provided significantly higher curcuminoids, including; curcumin, demethoxycurcumin and bisdemethoxycurcumin, thanthat of 400 watt. The extended extraction time increased curcuminoid content then stable after 3 minutes.The optimum curcumin extraction conditions were 800 watt microwave power and 3 minutes extraction time.This condition of MAE could provide good qualities of extract; 21.00%yield, total phenolic content (161.38?3.56 mg GAE/g extract), EC50(32.34?0.97 ?g/ml), curcumin (227.86?0.35mg/g extract), demethoxycurcumin (136.26?0.56mg/g extract) and bisdemethoxycurcumin (67.08?0.18mg/g extract). Application of curcuminoid extractin germinate-coated rice varied curcuminoid extact at 0.5, 1.0, 1.5 and 2.0%w/v. The results showed that consumers liked coated rice with curcuminoid extract at 1.0% most. Therefore, the extraction of curcuminoid by using microwave are benefit in savingtime and solvent ,and also provide high quality and efficiency of extraction. |
