摘　　要：明胶是一种重要的食品添加剂,主要来源于猪、牛等动物的骨和皮。在伊斯兰教的宗教信仰中,禁止食用含有猪源性成分的产品,因此对于食用明胶中猪源性成分的检测至关重要。该文主要对近年来国内外有关明胶中猪源性DNA或蛋白质成分的检测方法及优缺点进行了阐述分析,并对未来检测方法的发展趋势进行了展望。由于食品在加工过程中会发生DNA和蛋白质降解,故对样品进行前处理显得尤为重要,因此该文同时对样品前处理方法进行了总结评价。As an important additive in food industry,gelatin mainly comes from the bones and skins of pigs,cattle and other animals.However,in the Islamic religious belief,it is forbidden to eat products containing pig-derived ingredients,so the detection of pig-derived ingredients in gelatin is very important.In this paper,the methods for detecting pig DNA or protein components in gelatin at home and abroad in recent years,as well as their advantages and disadvantages are expounded and analyzed,and the development trend of detection methods in the future is prospected.In addition,it is particularly important to conduct sample pretreatment due to the degradation of DNA and protein in the process of food processing.And finally,the sample pretreatment methods are sorted out to some extent.
