herbal extracts and essential oils microencapsulation studies for different applications

Studies on bioactivities of numerous essential oils (eos) and herbal extracts compounds against diseases are crucial. microencapsulation methods development might be an alternative to obtain bioactive compounds for cosmetics and pharmaceutical uses. in this study, we carried out a literature review of 219 503 data articles using sciencedirect, redalyc, web of science, scopus, scielo, and google scholar databases in english and spanish, after with inclusion (original articles, book chapters, and theoretical references) and exclusion criteria (frameworks description), we found 1854 restricting the publication years between 2004 and august 2020 and 35 relevant articles with our scope research. references found contained a collection of methods that could be utilized to create microcapsules, including coacervation, extrusion, polymerization, and spray drying. this article analyzed the most recent and advanced microencapsulation techniques and their applications in the food, cosmetic, and pharmaceutical industries. herbal extracts and eos have many applications, depending on the wall materials and microencapsulation methods that could help know about selective release and efficacy to ensure optimal dosing and other advantages; thus, improving the profitability of these product manufacturers.
