Abstract;The interest for orgnically cultivated coffee has grown during last years because of increasing consumer concerns related to environment and food safety. Organic coffee production is enhancing gradually to meet the demand of strong economical markets like the EC, Japan and the USA. Due to the more laborious production process and fair trade principles, the price of organic coffee is higher than the conventionally produced coffee. Importers, however, are facing numerous problems in the discrimination of organic coffees from other coffees in order to discover and avoid frauds. Because higher international market prices are achieved by organic coffee and current discrimination strongly relies on "designation" certificates, there is an incentive in the market to sell conventional coffees or mixed coffees as being pure "organic". Appropriate identification of organic coffee means protection to producers and consumers, as well as mew perspectives for international trade. This identification may be based on the determination of the agrochemical compounds and residues, which is to some extent troublesome due to the high costs of the associated standards and to the fact that only very few such standards are available. Therefore it has been assessed if the elemental compositional characterization of organically and conventionally produced coffee could serve the same purpose. This work is an attempt to establish "fingerprints" of orginal lrganic coffee, aiming at "demonstrating" that t is what the seller "claims" it to be. In order to achieve this objective, samples of Brazilian coffee beans produced by organic and conventional method were taken from farms in the Minas Gerais State, Brazil, and elemental concentrations determined by instrumental neurton activation analysis(INAA). INAA is an advantageous technique for this kind of study since it is considered a primary ratio-method used for validation purpose without matrix-matching multi-elemant standard. (author abst.)
