Dear Milkologists,

Thank ewe for your contribution to the world of milk.

Is it true that Milk changes pH as it heats up ?

why's that then ?
Is it the same for Moo Juice, Sheep and Goat Milk, .........Breast Milk ?....any milk ?


whajafink ?






Hugs and milky shmishes

Water changes its pH with temperature.
Why wouldn't milk?

Oh come, on, BC!

Milk contains all sorts of organic goodies in solution and suspension that undergo all sorts of reactions when it's heated above body temperature.

Time for my learned friend to strut his stuff, surely?

Milk is basically water, protein, lactose, minerals and lipids( colloidal ). I don't envisage any great ph change unless exposed to fierce heat but small changes could be expected mainly from protein degradation. PS Alancalverd, I know you were referring to BC and not me.

Thanks BC... I didn't know that about water ....... so,I thought, this being a science forum I could ask the question 


I still want to know why and how PH levels change due to a rise in temperature ?

Thank you.....do you know why protein degradation could change the PH ? and is the temperature change prerequisite for the protein degradation to occur or could we just wait for the milk to go off ?
