Abstract
Proteinaceous materials such as yeast and soy flour can be treated with anhydrous ammonia gas at conditions sufficient to cause exothermic absorption of the ammonia to achieve improvements in certain properties such as texture and flavor.
Claims9
A method for improving the texture of spray-dried yeast comprising exposing the spray-dried yeast to gaseous anhydrous ammonia at a treating temperature of from about 0.degree. C. to about 100.degree. C. and an ammonia pressure of from about 15 to about 45 percent of the vapor pressure of liquid ammonia at the treating temperature for from about 15 minutes to about 2 hours.
