Abstract

Milk is a product of biological origin and can accommodate any additive without apparent changes in its appearance. Milk is the almost perfect food that supplies all necessary nutrients hence its quality needed to be checked for adulteration. In the present investigation milk samples were collected from local dairy farmers (cow and buffalo breed) and analyzed in the laboratory for quality testing specifically adulteration in milk. The received raw milk samples were tested in laboratory for electrical conductivity and refractive index as control (T0) and then adulterated with water, sugar, starch, urea and salt of the concentration as treatment T1 (1%), T2 (2%), T3 (3%), T4 (4%), and T5 (5%), of the milk sample each respectively. The efforts were made to detect adulterants as to render the values of electrical conductivity and refractive index for these adulterants. The existing methods also were used to confirm these adulterants. Lots of test are generally carried out to test the various adulterants hence lots of rupees are also spent. The cost of production can be minimized by testing electrical conductivity and refractive index. If sample showing lower or higher electrical conductivity or refractive index means it is adulterated. Therefore only suspected samples should be separated and tested for specific test. In this way one can save cost of production and time on milk processing. From the present investigation it is concluded that various cow and buffalo breed milk has a specific value of electrical conductivity and refractive index. The electrical conductivity and refractive index of milk get changes when it is adulterated with water, starch, sugar, urea and salt.
