Paper Abstract

Natural extracts or essences are largely used in several fields (farm- produce industry, cosmetic, perfumery, biochemistry, etc.). However, most of these complex extracts contain also toxic, carcinogenic or non desirable molecules. By using a laser directly tuned to an absorption band of the unwanted molecules, selective elimination is obtained. Advantages of this procedure are the rapidity, in situ reaction and the possibility to perform quantitative elimination. Examples such as the destruction of thujone in extract of Salvia, bergaptene in essence of Bergamote, phycocyanin in Porphyridium Cruentum or simply dye will be presented and discussed.
