چکیده انگلیسی
The aim of this study was to evaluate the effectiveness of gamma radiation from 60Co at doses 0, 5, 10, 15 and 20â¯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 (pâ¯<â¯0,05) of total phenolic compounds in the samples irradiated with 15â¯kGy (pâ¯=â¯0001) and 20â¯kGy (pâ¯=â¯0001). Regardless the irradiation, there was no decrease in the ability to scavenge free radicals. The Antioxidant Activity Index (Rancimat® method) was significantly lower (pâ¯<â¯0,05) in 5â¯kGy (pâ¯<â¯0001) and 15â¯kGy (pâ¯=â¯0003) irradiated extracts and the curcumin quantification was significantly lower (pâ¯<â¯0,05) in 15â¯kGy irradiated extract (pâ¯<â¯0001). It is concluded that gamma radiation processing technology on turmeric can be viable. To maintain safety of antioxidant activity it should be applied doses up 10â¯kGy.
