System and method for aflatoxin detection

摘要

A nondestructive system and method for aflatoxin detection based on red-orange fluorescence is described. A sorting plane is illuminated with a wide band black light source. At least one image of unsorted produce on said sorting plane is obtained. A red component of the at least one image is evaluated. Contaminated produce is determined based on the red component.

主权项

1. A nondestructive aflatoxin detection system comprising:
a chamber comprising an imaging stage and a sorting stage; a sorting plane in said chamber configured to receive bulk unsorted produce from a produce source, said sorting plane further configured to move said unsorted produce from said imaging stage through said sorting stage; at least one wideband black light source configured to illuminate said unsorted produce and highlight aflatoxin in said unsorted produce at said imaging stage; at least one imaging device at said imaging stage configured to capture at least one image consisting of Red, Green, and Blue component channels of said unsorted produce; an image processing device configured with at least one processor and computer memory coupled with said at least one imaging device, wherein said image processing device is configured to evaluate said Red component channel of said at least one image of said unsorted produce, wherein said image processing device is further configured to determine contaminated produce based on evaluation of said Red component channel in said at least one image of said unsorted produce; and at least one separation device in said sorting stage coupled with said image processing device, wherein said separation device is configured to remove said contaminated produce from said sorting plane.
