SUMMARY:

 The Brazil nut is one of the main products of Brazilian agro-extractivism, representing the main source of income for around 60,000 families and involving cooperatives, community organizations and associations. One of the many challenges to guaranteeing the quality of products made from Brazil nuts is the occurrence of aflatoxin. In this way, this study seeks to analyze strategies for decontaminating aflatoxin from the Brazil nut cake using non-thermal means, jet plasma and UV-C. To do this, it was necessary to carry out the processes for obtaining the Amazon nut cake, analyzing the rates of aflatoxin transfer from the seed to the cake on a laboratory scale. Then the treatment of the cake will be carried outby non-thermal means, and subsequent examination of the total aflatoxin by HPLC coupled to fluorescence detector content in the cake, before and after the application of the treatments, allowing us to determine which method is more efficient in decontaminating  of Amazonian nut cake. Some quality parameters will be analysed in order to determine the influence of the decontamination treatment process on the quality of the raw material.
