The term adulteration means that any matter which could be mixed with any substance to generate it in more quantity. Due to this process, the food or desired product has been compromised. And once it has been compromised then, the quality of food is compromised. Once the quality of the product is lowered through adulteration, then the product should not be consumed. Then it should be destroyed because it may be injurious to health. The primary reason for these mixing is that availability to everyone.

According to the registered records, many customers are in the daily need for milk products. So to fulfill the requirement for every customer is very hard, maybe that’s the reason adulteration is happening. Especially an increase in demand in the festive season is also a significant problem.
