Effect of gamma radiation processing on turmeric: Antioxidant activity and curcumin content

The aim of this study was to evaluate the effectiveness of gamma radiation from 60Co at doses 0, 5, 10, 15 and 20 kGy on turmeric (Curcuma longa Linn.). The quantification of phenolic compounds was performed by Folin-Ciocalteu method and assessing the potential of antioxidant activity by the free ra...

Zusammenfassung:The aim of this study was to evaluate the effectiveness of gamma radiation from 60Co at doses 0, 5, 10, 15 and 20 kGy on turmeric (Curcuma longa Linn.). The quantification of phenolic compounds was performed by Folin-Ciocalteu method and assessing the potential of antioxidant activity by the free radical [2,2 difenil-1-pricril-hidrazil (DPPH•)] scavenging and by Rancimat® method. The curcumin quantification was performed by High Performance Liquid Chromatography. Compared to control, there were significant losses (p
