STEAM STRIPPING AN AQUEOUS SLURRY OR SOLUTION OF PROTEIN TO REMOVE OFF-FLAVORS ABSTRACT A method for removing lipid-oxidation off-flavors from vege- table proteins, especially soy protein used in soy beverages, is disclosed herein. In this method, an aqueous slurry or solution of protein is formed into a film. This film is stripped with steam at a temperature of from about 200° (93°) to about 400°F (204°C) to remove off-flavors from the protein. The off-flavor laden steam is then separated from the stripped film. The stripped film is preferably cooled to a temperature of from about 90° (32°) to about 180°F (82°C) within about 1 to about 100 seconds after steam stripping begins. This method provides sufficiently bland soy protein without the need of recycling the slurry or solution as in prior methods.
