Abstract: The cleaning step of a packing line for fresh tomatoes is very important, because it removes surface residues of fruits; however, there are few methods used for evaluating the effectiveness of the cleaning process. The main goal of this work was to evaluate two new methodologies for evaluating the effectiveness of the cleaning process. The methodologies applied were the ones that used colorimeter and turbidimeter. The assays were carried out at the laboratory, in a cleaning step on a prototype developed and named UNIMAC (Harvesting aid equipment for tomatoes). Rubber spheres, with similar tomato weight, were artificially dirtied and submitted to the cleaning step on the prototype, with brushes of nylon bristles and rotation of 100 rpm. The results observed from the colorimeter method showed low accuracy and some limitations. This methodology did not give a representation of the dirt that remained on the spheres and, consequently, the process effectiveness. The turbidimeter method most precisely evaluated the spheres cleaning process, being this method the most effective.
