摘要

Milk is the perfect food for all human beings. Because it provides essential fatty acids, vitamins, inorganic elements, water, and amino acids. As per a research statistic out of milk produced by 4500 living mammalian species, only about 180 have undergone significant milk investigations, and approximately 50 are considered reliable sources of information due to adequate sampling and coverage of the lactation period. As per available data Uttar Pradesh is the largest milk producing state in India. 319 lakh metric tonnes of milk per annum was produced in the year 2022–2023. On the other hand, Per Capita Milk consumption as per records in Uttar Pradesh (U.P) is approximately 426 metric tons of milk. Therefore, the production is less than the consumption value. This has led to the serious problem of adulteration as people need to consume milk because of the various benefits that it offers. Prevention of adulteration of milk is one of the best solutions. Milk can be adulterated free only if the input is of good quality, then the output shall also be good provided that no interference or manhandling is done midway till the milk reaches the consumer. In this paper, an experimental set up is design and developed for identifying the milk adulteration using electrical parameters and colored light passed through it. The identification of milk adulteration is done using electrical resistance measurement and amount of colored light (red, green and blue) passed through the milk. This method is cheap and effective. The results are compared for different adulterated milks and pure milk.
