Liquid Buttermilk There are two types of commercial buttermilk, cultured and acidified.

The acid thicken the milk and produces a sour flavor.
Buttermilk Powder The buttermilk is first pasteurized, then concentrated with an evaporator and finally dried (spray or roller dried) to produce buttermilk powder.
