New way of definition of an androstenon

By means of "an electronic nose" the problem of detection in salted pork fat of an androstenon is solved, even small concentration of which negatively affect consumer appeal of a product. The massif from eight differently selective gas sensors is applied to detecting of an androstenon. The massif is previously trained on easily volatile compounds of various classes (alcohols, ketones, water, nitrogen-containing connections). Significant differences in analytical signals of the massif of sensors at the maintenance of an androstenon in model test of salted pork fat at the level of 0.5 threshold limit values are established. Except an androstenon in crude salted pork fat also early signs of damage and also the overestimated moisture content are reliably fixed. Changes in test of salted pork fat at violation of storage conditions also authentically are registered a set of sensors though at the same time changes in color and a salted pork fat smell by tasters are not recorded...
