This current review article is focused on a comparative account of various formulation techniques based on their applicability. For the first time, it also reviews various physico-chemical techniques used in the analysis of EO encapsulates to determine their stability, structure, surface morphology, and encapsulation efficiency. Further, the mechanisms involved in the release of EOs from encapsulates, along with various factors affecting their release, have also been discussed. ? 2016 Taylor & Francis Group, LLC.en-USChemical analysisChemical stabilityEncapsulationFunctional polymersNatural polymersEncapsulation efficiencyPhysico-chemical characterizationPhysicochemical propertyPhysicochemical techniquesPreparation techniqueSustainable releaseEssential oilsReviewhttps://www.tandfonline.com/doi/full/10.1080/15583724.2015.1123725
