Easy-to-use analytical approach based on ATRFTIR and chemometrics to identify apple varieties under Protected Designation of Origin (PDO)
We have tested seven varieties of apples from five different taste-classes. The method is able to identify apple classes based on the FTIR profile of their skin. It is a non-destructive method as it needs circa one square millimetre of skin. LDA yields a 91% success in the classification.
