Abstract
coexisting additives like surfactants or lactose were detected with high sensitivity in-dicating that the tested beverage had been adulterated by a foreign substance. Back-ground subtraction of the reference beverage mass spectra from those of the samples also enabled clearer and more reliable determination of the adulterants. The present-ed PESI MS method enables accurate screening in two minutes per sample with only a very simple pretreatment, applicable for large-scale screening of adulterants in foods and beverages. This method can serve as an extremely eŠective screening tool in combination with conˆrmatory instrumental analysis methods for identifying foreign
