Assessment of dairy products quality by means of electronic nose. The electronic nose, instrument that uses a group of sensors and a system of pattern recognition for the qualitative analysis of aroma, has found many applications in the food industry, because of its versatility. In this work a brief description of the electronic nose, its operation mode and its advantages and disadvantages were carried out. Moreover, the main applications of this instrument in the food industry, with special emphasis on the dairy industry, have been reviewed. These applications include the detection of microorganisms in milk, the identification of off-flavours in milk, the shelf life of milk and various types of cheeses, the identification of mastitic milk, the classification of cheeses according to their time of ripening, the discrimination of cheeses by geographic origin and the control of the milk fermentation, among other. The results of this review indicate that electronic nose could be used as an instrument for the rapid quality control of dairy products.
