IC CAPRINO kit is a qualitative test to detect the presence of goat’s milk in sheep's milk. The test is an immunoassay based on the detection of caprine immunoglobulins (IgG) in milk and cheese samples.
Milk with high economic value is commonly adulterated with milk from species of lower cost. This adulteration is especially important for cheese makers, due to unknown milk mixtures produce changes in the final sensory properties and reduce the product quality. Besides, pure cheese cannot contain milk from other species.
The unknown mixture of milk from different species is a common fraud in dairy sector. Sheep milk is more expensive than goat or cow's milk and tends to be adulterated with those of lower cost. This adulteration is important, not only for economical reasons, but also because unknown milk mixtures produce changes in the final sensory properties and reduce the product quality. Besides cheese producers need to assure that pure cheese does not contain milk from other species for labelling purposes. IC kits are lateral flow tests for species identification of milk and cheese.
