PROTEIN...CAN IT BE FROZEN

Hi All: I have a question concerning protein. I know that you can't heat protein past a certain temperature. Can you freeze it. There are a few recipes that call for protein but the entire recipe is too large for one sitting and would like to have it for other times. This is a recipe for a cold item so reheating is not required just defrosting. HELP!!!! Jeanne

hi jeanne are you putting powder or liquid protein into the recipes?? Roberta

hi again jeanne i just googled if you can freeze protein -- and i'm sitting here like a moron and not finding what i'm looking for BUT i work in a group home and i have seen people freeze milk -- and nothing happens to it -- we freeze meats and nothing happens to it -- there are many things that we throw in our own freezers and think nothing of it and it contains protein so i would guess that if you made a recipe with protein in it -- either powder or liquid -- that it should be fine don't know why i over-complicated this answer take care HUGS Roberta

Hey Roberta: Hope all is well with you. I have been following your progress and you are doing great. My concern about the protein is changing the chemical thing in it. You know how they say don't heat protein because at a certain temp, I think it 180 degrees, it changes the potency(?). Like you I freeze everything, but I don't want to make this recipe (powder protein) and then find out the protein is not going to be a counter. Do you think our Nut. Jim would know? Thanks for getting back to me. Jeanne

http://jds.fass.org/cgi/content/abstract/78/2/260 =Factors Affecting the Denaturation and Aggregation of Whey Proteins in Heated Whey Protein Concentrate Mixtures = "Whey protein concentrate (65% protein) mixtures, alone or in the presence of NDM, were heated at 66 and 71°C for up to 120 min...resulted in 6 and 20% denaturation after 120 min ..." In short, 151 to 160 deg F for 2 hours was only able to denature 20% of the whey protein. Unless you are planning to boil your whey for hours on end.. it is not somethign I would worry about As for freezing.. Whey is a milk by-product.. Simply.. Ice Cream.

Thank you very much. Jeanne
