Abstract
A dry porous macromolecular matrix is prepared comprising a cross-linked mixture of 69.9 to 86.6% by weight of an inert protein 0.4 to 10.2% by weight of a lipase enzyme and about 11.7 to 23% by weight of a cross-linking agent. The matrix is prepared by reacting the lipase, inert protein and cross-linking agent in a buffer solution, freezing the resulting reacted mixture at a temperature ranging between -20.degree. C. and -195.degree. C., allowing the frozen mixture to thaw to a temperature ranging from 4.degree. C. to 25.degree. C., and rinsing and drying the resulting product at room temperature.
