  • Process for dry coating a food particle or encapsulating a frozen liquid particle
    Patent number: 7163708
    Abstract: A process for dry coating a food particle having a size in the range from about 0.5 mm to about 20.0 mm is disclosed. The resulting coated food particle has a moisture level that is substantially the same as the moisture level of the uncoated food particle. A process for encapsulating a frozen liquid particle having a size in the range from 5 micrometers to 5 millimeters with a liquid coating material is also disclosed. Also disclosed are coated food particles and encapsulate frozen liquid particles made by one of the processes of the invention.
