Abstract
Microcapsules containing oil-based biologically active compounds which are stable over extended time periods for release of the encapsulated compound in the intestine. There are a number of biologically active compounds having an oil base which must be orally ingested in order to have a beneficial effect. An example of one such biologically active oil-based compound is a fish oil having a high content of polyunsaturated omega-3 fatty acids which has been demonstrated to reduce plasma levels of triglycerides, very low density lipoprotein, low density lipoproteins and cholesterol in normal and hyperlipidemic subjects. The disclosed microcapsules eliminate the unfortunate problems of the unpleasant taste and smell of the fish oil, as well as the aftertaste, particularly when ingested in large quantities, and provide a palatable and practical means of ingesting efficacious quantities of fish oil. In addition, the normal oxidation of polyunsaturated fatty acids is inhibited.
