Generally, pH of skim milk was approximately 6.8 at 25 oC. Is the pH increase upon decreasing the temperature (Refrigeration) of the skim milk?
Hi,
Please look in the web site
Article Effect of temperature on the pH of skim milk
Cooling cause a decrease in pH value , and this decease is depend on time of cooling .

If milk become cold pH decrease
by lowering the temperature the PH decrease
Hi
Normally 6.6 to 6.7
Hi, when you are measuring pH, you must to use both the electrode (for pH) and the temperature probe for an automatic temperature compensation.
Most modern pH meters are equipped with a sensitive pH probe and a temperature probe. You will find the fresh sample of skim is about 6.5 to 6.7.
