Abstract

In order to encapsulate or coat one or more active substances with a material, a mixture is used as the encapsulating or coating material which consists of substantially natural starch and at least one agent which at least partly swells the starch and which, for the encapsulation or coating, is mixed with the active ingredient and at least one emulsifier. Preferably also added to the swollen starch plus active ingredient during mixing is at least one oily substance which substantially cannot form a homogeneous mixture or with which substantially no phase intermixing takes place bwteen the oil and the swollen starch. Mixing the swelling agent, emulsifier, oily substance and natural starch with the active ingredient is preferably carried out at elevated temperature in a mixing device such as a mixer, kneader or extruder.
