山羊牛奶和羊奶是牛奶越来越受欢迎的替代品。但是,消费者并不总是得到他们为的代价。用牛奶 - 故意或无意的掺假 - 并不罕见。
无论是鱼类,肉,橄榄油还是蜂蜜:食物欺诈都可以用许多产品发生。乳制品行业也受到严重影响。由于由山羊牛奶或羊奶制成的产品非常昂贵,因此与更便宜的奶牛牛奶掺杂可以有利可图。对于消费者来说,这种欺骗通常是不可能认识的。除了刻意的掺假外,牛奶还可以意外地进入山羊牛奶或羊奶,例如通过生产或运输过程中的污染。为了验证产品的真实性,适当的分析很重要。
新竞争力的ELISA测试“Europroxima Plus Cow牛奶”(艺术品。美国专利号5171milk)适用于从其他动物牛奶中检测牛奶。由于使用的抗体,该试验可用于原料牛奶以及热处理的牛奶和奶粉中。It is therefore suitable for quality control of incoming goods (e.g. to detect residues of cow’s milk in goat’s milk before a batch is processed further) as well as for quality control of the final product (e.g. to detect cross-contamination of goat’s milk powder with cow’s milk powder). The enzyme immunoassay is validated for different matrices from the dairy industry and has an incubation time of only 45 minutes. The quantitative results are expressed as percentage of cow’s milk in the sample. The following table shows the limit of detection and the detection capability of the test kit:
应用 | 检测极限(LOD) (牛奶的百分比) |
检测能力(CCβ) (牛奶的百分比) |
---|---|---|
在山羊/羊液体牛奶中检测牛的液体牛奶(v / v) | 0.2 | 0.5 |
山羊/羊奶粉(W / W)中牛奶粉的检测 | 0.2 | 0.5 |
在山羊乳清粉中检测牛的初乳粉(w / w) | 0.2 | 0.5 |
测试套件取代了以前可用的测试套件“Europroxima牛奶欺诈”(ART。美国专利号5171BKCM)。
