Abstract
Production of microcapsules containing glycyrrhetic acid comprises reacting chitosan with an anionic polymer in the presence of a gelling agent. Production of microcapsules with an average diameter of 0.0001-5 mm, comprising a shell membrane and a matrix containing glycyrrhetic acid (I), comprises either: (a) forming a matrix of a gelling agent, chitosan and (I), optionally dispersing the matrix in an oil phase, adding an aqueous solution of an anionic polymer and optionally removing the oil phase; (b) forming a matrix of a gelling agent, an anionic polymer and (I), optionally dispersing the matrix in an oil phase, adding an aqueous chitosan solution and optionally removing the oil phase; or (c) forming an oil-in-water emulsion from an aqueous preparation of (I) and an oil in the presence of an emulsifier, adding an aqueous solution of an anionic polymer, contacting the resulting matrix with an aqueous chitosan solution and separating the encapsulated product from the aqueous phase. An Independent claim is also included for microcapsules produced as above.
