Microencapsulation techniques allow compounds with bioactive properties to be applied in several industrial segments. There are several methods of microencapsulation, being considered ideal, those that present low cost, simplicity, reproducibility, and easy transmission on an industrial scale. Microencapsulation by ionic gelation is a method that uses the electrochemical interaction characteristics of the compounds, allowing the bioactive substance to be retained in its structure. In this sense, the present work aimed to prospect the technological evolution applied to the microencapsulation technique by ionic gelation. The first deposit was found in 1992, being 50% of which originated in Brazil. As for the profile of depositors, 55% were private companies linked to the pharmaceutical sector (40%). As for the main microencapsulated compounds, chemical and biological agents used in pharmaceutical products stood out (27.8%), followed by flavoring compounds and microorganisms, both with 16.7%. Therefore, the versatility of the technique is evident, with possible application in the various industrial segments.
