The Brazilian coffee is one of the most important product in the national and international trade, with emphasis on fungal and ochratoxin A (OTA) contamination. The caffeine is spotted among natural mechanism of defense capable to inhibit mycotoxins production, including OTA which is continuously discussed in the globalized world. Concerning that transgenic plants produced by molecular techniques are motive of serious barriers in the food safety, the classic toxin monitoring still continues option for safety problem solution. The disadvantages concerning chemical methods stimulated development of enzyme linked immunosorbent assay (ELISA), and imunoaffinity as promising alternative for the detection of OTA. With intention to guarantee the quality of coffee, the revision discerns about caffeine as a component of natural defense of plant, in parallel to highly sensitive simple tool, which can be indispensable for ochratoxin diagnosis at field level.
