Abstract

Ochrotoxin A in coffee is regarded as a potential hazard. Earlier reports suggest that the toxin is present in the outer husk than in bean. A detailed investigation was done on the colonization of toxigenic moulds like Aspergillus carbonarius, A. falvus and A. ochraceus from plant to processing of coffee bean. Results indicate that the colonization mainly occurs during post-harvest treatment. Among the types of drying yards concrete/cement floored yard is ideal as it inhibited the colonization of the molds. During processing high incidence of fungal colonization was observed in the low grade coffee bean like bits and blacks. Whereas on the plant the incidence of these molds are negligible. A controlled condition of drying can bring down the colonization of toxigenic group of molds
