Milk allergens detection in samples of cookies and tea biscuits

Food allergies are becoming a significant public health issue. The presence of unintended allergens in food and unintentional exposure to allergens are the biggest problem for sensitive individuals. In this study, the ELISA (Enzyme-Linked Immunosorbent Assay) method was used for the detection of the presence of unintended milk allergens in total of seventeen cookies and tea biscuit samples from the Zagreb market. Twelve samples were taken from supermarkets, and five from the pastry shops. The obtained results were also compared with food information. Among seventeen analysed samples of cookies and tea biscuits, milk allergens were detected in twelve samples (average 0.58 mg/kg in samples from supermarkets, and 0.14 mg/kg in samples from a pastry shops). Three samples from supermarkets (two of which with the highest milk allergens content ; 0.70 mg/kg) did not contain declared advisory label related to the presence of milk allergens. Food information about the presence of the milk allergens on the analysed samples of cookies and tea biscuits from pastry shops were not highlighted. The results of this study showed the importance of controlling the presence of unintended milk allergens in pre- packed and also in non pre-packed food, as well as the appropriate communication with the consumers facing nutritional allergy.
