Whipped Cream & Protein
Reader Mari asks:
Does the process for whipped cream involve casein too? I’ve always thought it was ironic that so many non-dairy cheeses and non-dairy whipped creams contain casein in them, which is what causes an allergic reaction to dairy products for a lot of people. I concluded that casein must have something to do with the structure of cheese and whipped cream. After all, there aren’t any other 38% fat/ 60% water mixtures that can whip up like cream does, right?
Interesting question, Mari! Casein is indeed fascinating stuff, and it abounds in milk (about 5% of milk is casein). You’re absolutely right that it’s critical for things like cheese and yogurt, since it clumps up together when it’s exposed to acid. Those clumps trap fat and water creating the large curds that make cheese, and the tiny curds that make yogurt and sour cream.
