Abstract
A catalyst preparation comprising an insoluble matrix and an enzyme complex immobilized onto said insoluble matrix, characterized in that the matrix contains active carbon. The content of the active carbon is preferably in an amount of 0.1 to 70% by weight, more preferably 1 to 40% by weight and most preferably 3 to 20% by weight, relative to the entire matrix. The enzyme, particularly a lipase, is preferably coated with a surfactant. The inorganic insoluble matrix is preferably a silica-based matrix or an ion-exchange resin. The catalyst preparation of the invention is intended for use as a catalyst in esterification, inter-esterification and trans-esterification reactions.
