In this paper we present results that indicate how electromagnetic irradiation influences aflatoxin BB1 (AFB1) concentration in nuts. The aflatoxin level was determined by the immunoaffinity chromatography with fluorimetric detection. First, peanuts as certified reference material (initial AFBB1 level fixed at 39.1 ng/g) underwent exposure to UV, gamma and microwave radiation. Decrease of aflatoxin content was strongly correlated with thickness of irradiated sample layer. 2mm layer samples exposed to ultraviolet for 30 min resulted in AFBB1 concentration drop by 49.3%, but 10 mm layer samples exhibited limited UV penetration into the material, giving comparatively weaker drop in AFBB1. In the samples exposed to microwave radiation in the range of 36 kJ - 150 kJ the residual aflatoxin content was about 50.0%, hardly depending on a dose of energy. The gamma radiation proved to be the most effective method. Individual samples exposed to 2.5 kGy, 5 kGy, 7.5 kGy and 10 kGy gamma radiation dose exhibited AFBB1 concentration reduction by 56.8%, 57.8%, 60.9% and 74.3%, respectively. Next, we used this method to the decrease of aflatoxin content in commercial nut products by exposure to 10 kGy dose of gamma radiation. We received the residual aflatoxin content less than 40% for almonds. (original abstract)
