Strains of fungi which produce ochratoxins were isolated in green coffee (Coffeaarabica) which was stored for seven months in three warehouses from a coffee-growingregion of Mexico. The same time the OTA content was determined using the immunoaffinitymethod. The values found initially (after two months storage) fluctuated between 1.2 to 7.7ppb and then did not vary significantly after the following five months. While these valueshave not increased to levels not permitted during storage due to natural conditions ofhumidity and temperature characteristics of the study region; 100% of strains of Aspergillusniger were found to potentially produce these mycotoxins under uncontrolled conditions oftemperature and humidity. For this reason, this document presents the quantificationTM ochratoxin A in green coffee with Ocratest , with an assessment of the ability of OTAproduction by native strains of Aspergillus in three coffee industries different in Mexico.mycotoxins; green moulds; coffee beansDownloads
