ENCAPSULATION

摘要

A method of encapsulation comprises the steps of: (a) treating microbial microcapsules with a material to be encapsulated in a substantially anhydrous liquid medium containing a polar aprotic solvent having a dielectric constant greater than 35 under conditions to permit encapsulation of the material, and (b) subjecting the product of step (a) to a substantially aqueous liquid. The preferred solvent is dimethyl sulfoxide (DMSO). The method of the invention is useful for encapsulating hydrophobic and/or high molecular weight materials in yeast.
