PREPARATION OF HIGH SOLIDS AND HIGH PROTEIN LACTOSE-FREE ASEPTIC MILK CONCENTRATES AND MILK POWDERS WITH FORWARD OSMOSIS

摘要

Disclosed are methods for preparing aseptic dairy compositions having at least 35 wt. % solids, and often from 40 to 50 wt. % solids, by subjecting a dairy product to forward osmosis following by a heat treatment step. The heat treatment step can include UHT sterilization via direct steam injection or direct steam infusion. Subsequently, the aseptic dairy composition can be dried to form a dairy powder composition.
