Studies on radiation stability of natural caffeine

Appl Radiat Isot. 2022 Feb 15;183:110148. doi: 10.1016/j.apradiso.2022.110148. Online ahead of print.ABSTRACTBehavior of isolated caffeine in 60Co- γ radiation environment was studied in solid form as well as in aqueous medium. No degradation in solid caffeine structure was observed after exposing up to a dose of 10 kGy. In aqueous medium, 98% radiolytic degradation of caffeine was observed after application of 1.26 kGy γ dose. Radiation chemical yield decreased with increasing dose. The degradation was mostly favored in neutral medium. Addition of ethanol decreased the radiolytic degradation efficiency.PMID:35193082 | DOI:10.1016/j.apradiso.2022.110148
