Whey fermentation process.

摘要

A process for manufacture of fermented whey having a high concentration of propionic acid comprises subjecting the whey medium having a solids content ranging from 0.5% to 18% by weight to a sterilization step of direct steam injection, for a period of 4 to 12 seconds. The sterilized whey medium is then inoculated with a propionic acid-producing bacterium and incubated for a sufficient period of time to maximize the fermentation.
