The allergy to milk is to be distinguished from the lactose intolerance: in the case of intolerance, the symptoms are caused by a certain type of sugar (milk sugar, lactose), in the case of allergy, however, by certain proteins in the milk. Milk allergy is an allergy in the classic sense, i.e. the immune system fights a substance that is actually harmless to the body and allergic symptoms arise. Milk is consumed directly, as a drink, or as a processed product such as cream, butter, yogurt or cheese. Cow’s milk powder is widely used in baked goods, sauces and dessert.

Cow`s milk contains 3.2 % proteins which consist of 10 % β-lactoglobulin (leading protein of whey) and 80 % caseins. Casein is heat-stable, while ß-lactoglobulin is heat-sensitive. Most milk allergy sufferers are allergic to both protein fractions in milk. The most important allergen for children is β-lactoglobulin while the caseins become to be dominant later in adults. The allergen can be present as an ingredient or as a contamination in raw and cooked products. According to the regulation (EU) No. 1169/2011 milk and products thereof must be declared on food labels. Similar regulations exist e.g. in the USA, Canada, Australia and New Zealand.

Milk contains approx. 3.2 % milk protein. Thus, a sample which contains 1 mg / kg milk protein corresponds to a milk content of approx. 31 mg / kg milk.


The ELISA RIDASCREEN®FAST Milk was approved and has been certified by the AOAC Performance Tested MethodsSM Program and was assigned PTM Certification No. 101501 by the AOAC Research Institute.
