milk fat substitutes, calcium chloride and many other bad things
Just because this comment can be easily misinterpreted:
Milk fat substitutes are just plant oils.
Calcium chloride is what they inject into you if you have a severe calcium deficiency. It's just calcium salt. Your regular table salt is Sodium chloride. Nigari is magnesium chloride used to make tofu. All three are salts that can be extracted from normal seawater.
Both plant fats and CaCl2 are natural, neither of them are "bad" (when, like everything, they're consumed in sensible amounts) and they should not be lumped in with "other bad things", even if you don't like those ingredients in your cheese.
