Malyk O. The method of quality control of milk by electrical parameters

The dissertation is dedicated to the actuals problems of measuring quality characteristics of food products, such as cow's milk. As a result of scientific experiments in high-frequency electromagnetic field dependencies amplitude of output and input signals and phase shift of the frequency and composition of milk, allowing for these parameters promptly determine and control its characteristics The dependences of the amplitude of the output and input signals and phase displacement sensor for different composition of milk at a constant voltage level of the test signal frequency range from 1 MHz to 10 MHz. We found that with increasing frequency response rises to a certain point and then begins to decrease. The dependences response characterized by extreme values 6 MHz on separate frequencies , with each frequency value corresponds to a high quality of milk. Milk fat is an important indicator of milk quality, characteristic frequency 6 MHz , in which the response becomes of extreme importance. This allows us to offer electric method as a method for obtaining qualitative and quantitative information on the composition of milk, using the parameters of frequency response and phase response as informative , as well as the structure of a means for its implementation. Proposed design methodology for determining the quality of milk by the method of electrical operational control characteristics of milk.
