Hi friends,
For a week I'm surfing internet to find a specific heat of yogurt.
There are specific heat of most of dairy products, milk , foods and ….. but I didn't find specific heat of Yogurt.

Do any friends have source to read this parameter on it ?

Thanks for your help in advance.

Sincerely yours.

Scroll down and different types of yogurt are listed.

Trouble is down to density and content this will change the product.

............................... @ 15degC...........@ 30degC

Strained Yogurt...............0.540.................0.539
Light Yogurt ...................0.571.................0.583
Pasteurized Yogurt...........0.571.................0.593
Extra Light Yogurt............0.584.................0.596


also temp is a big factor

Hey Rob,
Just to make it more interesting, Is there a difference between cow's yogurt, sheep yogurt an goats yogurt and how much fat content changes the latent heat...

Personaly? Camembert would be better ...:)

First of all thank you very much for your help. "Thermal conductivity" is different with "Specific heat".
in that source you sent , I just saw material about thermal conductivity not specific heat.

Sincerely yours.

Have a look here...

Download the pdf file and search for "cp", formulae for specific heat.
