An Energy Dispersive X-ray Spectroscopy Analysis of Elemental Changes of a Persimmon Phytobezoar Dissolved in Coca-Cola

摘要

To investigate the mechanism of phytobezoar dissolution by Coca-Cola?, persimmon phytobezoar pieces removed from a 60-year-old Japanese woman were analyzed by energy dispersive X-ray spectroscopy. The amount of calcium significantly decreased after dissolution treatment using Coca-Cola?, suggesting a potential contribution of calcium to dissolution mechanisms. Moreover, immersion in Coca-Cola? for 120 hours on the exterior surface revealed that Coca-Cola? did not permeate persimmon phytobezoars. This is the first study to investigate the mechanisms of persimmon phytobezoar permeability and dissolution induced by Coca-Cola?.
