Abstract
Microcapsules comprising an active substance embedded in a matrix material obtainable by treating a pectic substance with one or more enzymes selected from the group consisting of esterases (E.C.3.1.), glucosidases (E.C.3.2.), peptidases (E.C.3.4.), proteases (E.C.3.4.), and lyases (E.C.4.), a process of preparing microcapsules and products containing such microcapsules.

Microcapsules comprising an active substance embedded in a matrix material, characterized in that the matrix material is obtainable by treating a pectic substance with one or more enzymes selected from the group consisting of esterases (E.C.3.1.), glucosidases (E.C.3.2.), peptidases (E.C.3.4.), proteases (E.C.3.4.) and lyases (E.C.4.).
A process of preparing microcapsules containing an active substance embedded in a matrix material comprising the steps of providing an aqueous medium of a pectic substance modified by treatment with one or more enzymes selected from the group consisting of esterases (E.C.3.1), glucosidases (E.C.3.2), peptidases (E.C.3.4), proteases (E.C.3.4), and lyases (E.C.4), adding to said solution at least one active substance, finely dividing and drying the mixture thus obtained to obtain a mass of particles each containing a plurality of liquid or solid micro particles of the active substance embedded in a matrix comprising the modified pectic substance.
