Abstract

Discrete entities of a solid suspension are made from a solid fat matrix and a non-fat solid substrate having an active associated with said substrate. These entities are spheroidal in shape, have uniform size and substantially the same active content due to the flash flow process used to make them. They are especially useful as delivery systems for comestibles, pharmaceuticals and personal products.
