Both Prunus species produce similar flavor and sensory profiles, but have significantly different costs—the 50% cheaper apricot kernels are sometimes used as an adulterant, replacing almonds in products such as marzipan, almond oil or almond powder. A polymerase chain reaction (PCR) method shows that the DNA barcode of almond shows significant differences from other Prunus species and can therefore be used to detect adulteration of almond products.
