Anhydrous butter oil or cream was encapsulated in all-purpose flour, modifi
ed cornstarch, or sucrose and then spray-dried. We estimated the processing
cost for a plant designed to produce 57,000 kg/d (125,000 lbs/d) of encaps
ulated milk fat powder. Powder with a 50% milk fat content could be produce
d for about $0.23/kg plus the cost of the butter oil or cream, the encapsul
ant selected, and the other ingredients. Spray-drying of milk fat improved
ease of handling and reduced storage costs.
