High Integrity Encapsulation Product with Insoluble Fibers. A particulate extrusion encapsulation product in a glassy state is described including an encapsulate, encapsulated in a glassy matrix. The glassy matrix includes at least one modified starch, at least one carbohydrate and at least one insoluble fiber. The load of the encapsulate is typically from 0.01% to 20% by weight, based on the total weight of the encapsulation product. A method of making the particulate extrusion encapsulation product and food products containing the extrusion encapsulation product are also described.
