تجزیه و تحلیل نسبت ایزوتوپ پایدار از تمشک های اروپایی مختلف، تمشک، زغال اخته، پیاز و توت فرنگی

The different soft fruits showed a typical range for one or more isotopic parameters that can be used to verify the authenticity of the fruit composition declared on the label. The δ13C and δ15N of pulp and the δ18O of juice can be considered effective tools for identifying the different geographical origin of fruit. A significant effect of crop cover on juice δ18O and fertilisation practices on pulp δ15N was demonstrated and must be considered with attention when evaluating data.
