Last years have been characterized by a growing interest toward natural origin products such as plant pigments and dyes or animal ones. The reasons of this interest are different, for example, the environmental pollution linked to synthetic dyes use, their toxicity occurring in health risks for workers and consumers and the increasing preference toward natural extract in commodities consumption. Recent restrictions (e.g. Directive EEC 61/2002) imposed by the legislation concerning the use of some synthetic dyes, in food and textile fields, make research and studies engaged in the valorization of organic dyes. The aim of this paper is to review only the plant species useful in natural dye production in alternatives to synthetic ones and to evaluate the market potentialities of this sector. Furthermore, a briefly description of extraction and applications methods are highlighted.

Abstract
Last years have been characterized by a growing interest toward natural origin products such as plant pigments and dyes or animal ones. The reasons of this interest are different, for example, the environmental pollution linked to synthetic dyes use, their toxicity occurring in health risks for workers and consumers and the increasing preference toward natural extract in commodities consumption. Recent restrictions (e.g. Directive EEC 61/2002) imposed by the legislation concerning the use of some synthetic dyes, in food and textile fields, make research and studies engaged in the valorization of organic dyes. The aim of this paper is to review only the plant species useful in natural dye production in alternatives to synthetic ones and to evaluate the market potentialities of this sector. Furthermore, a briefly description of extraction and applications methods are highlighted.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
