SPECTROSCOPIC METHOD FOR THE AUTHENTICATION OF VEGETABLE MATTER

Infrared spectroscopy, in combination with classical discriminant anal ysis, was used to investigate the composition of the cell walls extrac ted from a number of plant species. It was shown that apple cell walls gave rise to a characteristic spectrum that allowed the discriminatio n of apple from a range of other plant species. The conclusion drawn i s that infrared spectroscopy is potentially of value for the identific ation of plant cell walls, opening up the possibility that the techniq ue may be useful for the authentication of fruit-containing products.
