Effects of freezing on dairy products - yogurt

Hi All,
I would really appreciate your ideas of where to find reliable information regarding the effects of freezing on dairy products, specifically yogurts. I am referring to freezing the product with view to thawing it prior to consumption, not to produce "Frozen Yogurt". Is there a resource with this type of information?
Thanks in advance.

Dear J
you will be having the problem with the yogurt when u thaw it , so you need to add stabilizing agent to get the good freeze thaw stability in the proudct .regarding this you can add starches , starches gives the good freeze / thaw stability in frozen foods . try potato or topiacca and gums . let try this in product . for the yogurt, pregelatinized starches will work affectively because you not gonna cook this or if you gonna cook the milk before to make yogurt native starches will work better .

Hi JCommins,



Freezing breaks up the yogurt structure and it will become a 'sloppy mess' for want of a better description. As Saqib has indicated you will need to stabilise the yogurt. PM me if you would like a recommendation regarding a dairy stabiliser supplier.
