Abstract
Got milk takes now-a-days important place in production of specific and looked for dairy products owing to its composition. On account of its quantity and different price goat milk is often adulterated with cow milk. For quick detection and quantification of cow milk in goat milk immunoassays and electrophoretic methods are used. Radial immunodiffusion is one of immunoassyas applying CV Test (Levi eux, 1977). Milk sample is put in agar layer containing specific antiserum for cow milk. Measuring the difussion developed owing to known immunologic reaction with antiserum by means of reference curve it is possible to achieve the added proportion of cow milk quantities in analyzed milk samples. Applying CV Test in routine analysis enables quick detection of goat milk adulteration and, by that very fact, the use of pure goat milk in processing is of specific worth and asked for dairy products.
