the invention relates to microcapsules , and a continuous micro - encapsulation water - in - oil - in - water microencapsulation process through in situ and interfacial polymerization of the emulsion . the formulation comprises a continuous water phase having a dispersion of microcapsules which contain oil drops and wherein the inside of each oil phase drop — containing optionally oil - soluble materials — there is a dispersion of water , or aqueous extract or water dispersible material or water soluble material . the oil drops are encapsulated with a polymerisable material of natural origin . such microcapsules are appropriated for spray - dry processes , to be used as dry powder , lyophilised , self - emulsifiable powder , gel , cream and any liquid form . the active compounds included in the microcapsules are beneficial to the health and other biological purposes . such formulations are appropriate to be incorporated in any class of food , specially for the production of nutraceuticals , as well as cosmetic products . the preparations are adequate to stabilise compounds added to the food , media for cultivating microbes and nutraceuticals , specially those which are easily degradable or oxidizable .
