Milk is most commercially sold commodity both by local vendor’s as well super markets. However in local areas to increase the yield certain adulterants are added which may affect the nutritional quality of milk. Milk adulteration is a social problem. The Country milk producers and consumers facing problem to find the quality of milk, accept the fair of price and consumption. So it is necessary to ensure the quality of milk by measuring type and amount of adulterants that are added to the milk. This is performed by using combined electronic sensory instrumental system such as a temperature sensor, photo diode and two conductivity electrodes of different calibration one measures PH and the other measures moisture content in milk. All the sensors are combined to form compact and flexible system which analyse and classify the quality of milk into different grades and finally output displayed through mobile app. Problem faced in small diary industries and by the individuals can be prevented by detecting the quality of milk. By using PRESTO analyser milk quality analysing parameters like FAT, SNF can be measured. The conventional methods of analysis of food products include expensive and sophisticated instruments. Such instrumental assessment techniques are time consuming, tedious, expensive and require elaborate sample preparation and in practice, expert human panels have to be employed to judge the qualitative parameters in the food and beverage industry. This method of assessment has some major drawbacks like fatigue, adverse mental state at times, and individual variability of human experts. PRESTO milk analyser reduces the problems faced by conventional method. It is more compact and portable in size.
