A chemical method was developed to determine the presence of mammalian feces in food. The method consisted of the colorimetric determination of alkaline phosphatase and involved the splitting of the phosphate radical and phenolphthalein diphosphate and the resultant color development of phenolphthalein in a basic medium. A collaborative study testing the feces of 22 animals resulted in a 95% correct identification of samples as mammalian feces. The method has been adopted official first action.
开发了一种化学方法来测定食品中是否存在哺乳动物粪便。该方法包括比色法测定碱性磷酸酶，涉及磷酸根和酚酞二磷酸的裂解以及在碱性介质中酚酞的显色。一项对22种动物粪便进行测试的协作研究得出，将样本正确鉴定为哺乳动物粪便的准确率为95%。该方法已被官方首次采用。
