Dear Mousavi,

Welcome to the forum! :welcome:

I presume you are referring to contamination due to detergents / disinfectants.

I am afraid that the answer may be yes or no depending on the specific contamination.

Dear Mousavi,

Milk not my specific knowledge area but the usual approach to yr question depends on the scope of yr query, eg (a) if information on all common contaminants / specific is required, (b) detection or actual measurement, © yr own situation, eg lab or ??, also has relevance.

If yr want a general answer, probably need a textbook on milk / food analysis, or perhaps an official standard . For example this link refers to the British Standard methodology for answering yr general question.

Another, I believe, standard (US) reference is Standard methods for the examination of dairy products (published by APHA).

If you hv a specific contaminant, same comment but a more specific search possible, for example google gives this old ref.for quaternary presence in milk detection

Attached File  rapid method for quaternary compounds in milk - PIIS0022030251917043.pdf   445.73KB   47 downloads

Unfortunately, I couldn’t find much direct on-line answer to yr question(s) but there are some “milk” people on this forum who can probably give a better answer than me ??

PS I also noticed this old item which might interest you -

Attached File  (Old approx. 1960) WHO monograph residues disinfection, antibiotics in milk.pdf   322.6KB   24 downloads

and also this link -

Yes, you could do an acidity test. Acitity of milk is about 0.12 to 0.18, cream is 0.08 to 0.11.

to test for detergents you could just taste it for taints.

I've never had the need to use anything more elaborate than that to be honest

:thumbup:

Agreed a taste test by a trained analyst is all that is needed. Quick, simple and effective.

Tony
