Rapid capillary electrophoresis approach for the quantification of ewe milk adulteration with cow milk
چکیده انگلیسی


- Ewe and cow skimmed milk proteins showed distinct CE profile in alkaline separation.
- An ewe specific CE peak protein allowed the quantification of ewe milk adulteration.
- CE method for ewe milk adulteration showed good linearity, precision and accuracy.

The substitution of ewe milk with more economic cow milk is a common fraud. Here we present a capillary electrophoresis method for the quantification of ewe milk in ovine/bovine milk mixtures, which allows for the rapid and inexpensive recognition of ewe milk adulteration with cow milk. We utilized a routine CE method for human blood and urine proteins analysis, which fulfilled the separation of skimmed milk proteins in alkaline buffer. Under this condition, ovine and bovine milk exhibited a recognizable and distinct CE protein profiles, with a specific ewe peak showing a reproducible migration zone in ovine/bovine mixtures. Based on ewe specific CE peak, we developed a method for ewe milk quantification in ovine/bovine skimmed milk mixtures, which showed good linearity, precision and accuracy, and a minimum amount of detectable fraudulent cow milk equal to 5%.
