Discrimination between Ascorbic Acid from Acerola and of Synthetic Origin by Measuring 13C and 18O Stable Isotope Ratios

We examined the 13C/12C and 18O/16O stable isotope ratios (δ13C, δ18O) of ascorbic acid from acerola and of synthetic origin. Although the obtained δ13C values were partially overlapping for the tw...
