Abstract

A new method of detecting milk allergen protein in food was established. Using multiple reaction monitoring (MRM) mode in high performance liquid chromatography-mass spectrometry (HPLC-MS) to detect milk allergen protein α-casein is successful and convenient. All transitions gave a linear response in the chosen concentration range of the milk allergen protein (between 0. 5 and 250 mg/L total soluble protein, 5 data points), and the detection limit is 0.5 mg/L of α-casein. Food samples from markets were tested. The results showed that MRM method could be used to detect the milk allergen in food products.
