摘要

This paper describes the development of a new method to obtain aqueous-core microcapsules from organic-core capsules.The direct production of microcapsules,using tripropionin as organic material,followed by the hydrolysis of the core by a lipase was investigated.The enzymatic study showed that the enzyme obeyed a Michaelis-Menten mechanism and conditions for optimal activity were pH 7.5,25-37°C and 0% NaCl.Under these conditions,incubation of tripropionin-alginate microcapsules in a buffer containing the enzyme successfully produced aqueous-core capsules with reduced accumulation of alginate in the core in ~3h.
