Use of information technology in the evaluation of contamination in flour.

Summary During the flour manufacturing process flour may be contaminated resulting in lower quality. Before placing a product in the commercial circulation flours are subjected to laboratory analysis, including in terms of product purity. This analysis is based on organoleptic determination (through visual inspection) of the amount of impurities in the flour and in the cereal products. This paper presents innovative techniques to assess quality in terms of pollution of flour using image analysis and artificial neural networks (ANN).
