I am very much new in this field and trying to get some information on adulteration of cow milk. I have searched and saw that mostly urea and hydrogen per oxide are mixed with cow milk.

I found that to quantify adulterants in milk, Fourier-transform infrared spectroscopy (FTIR) can be used. Normal cow milk contains (20-70)mg/100ml urea. So, urea content above 70mg/100ml in milk is considered as added urea.

I want to know the exact proportion/amount of urea and hydrogen per oxide are mixed in the cow milk as adulterants. I need to carry out the experiment by adding urea/hydrogen per oxide in pure cow milk to get the desired spectrum in FTIR.

Is it in between 71-100mg or more or in which range actually?

Can anyone point me out any reference? Thanks in advance.

  • $\begingroup$ FTIR analysis falls squarely in the domain of chemistry SE. This questions should definitely be moved over there. $\endgroup$ – ericksonla Jul 23 '18 at 18:56
