Surface Level Detection of Aflatoxin B1 Using Sensor in Groundnut

Abstract

Aflatoxin B1(AFB1) is a member of a group of mycotoxins produced by Aspergillus flavus and A. parasititus. Aflatoxin B1(AFB1) is the most hepatotoxic and hepatocarcinogenic of the aflatoxin and occurs as a contaminant in a variety of foods. Aflatoxins causes both acute and chronic toxicity in humans. Certain farm produces like corn, groundnuts and tree nuts are easily contaminated. Aflatoxins occur mostly groundnuts. International bodies have specified four parts per PPB of Aflatoxin to be acceptable in international market. Aflatoxin accumulating fungi can infect groundnut during the production season as well as during post- harvest handling. If groundnuts are sorted out which are infected by Aflatoxin fungi to 98% it will help farmers to get better prices and export market. Unfortunately, manual sorting is in question because of human exhaustion working for long hours or sorter unable to take decision. In this project aimed at automating sorting based on the RGB values. Decision is taken separate good groundnut from infected groundnuts based on the values of primary colours. The machine is designed and developed in which using servo motor groundnuts are passed below TCS3200 sensor which sends outputs to Arduino Uno for analysis, comparison and deciding whether
the groundnut should be rejected or retained. The Arduino is programmed to do the comparison and take decision. This machine will improve the sorting capability which otherwise.
