EO was encapsulated in rice starch porous spheres, inulin and gelatine/sucrose capsules by spray drying. Gelatine/sucrose matrix was also dried by freeze drying. Experimental designs were applied to test the effect of bonding agents and solids content for rice starch and drying temperature and solids content for inulin and gelatine/sucrose systems. The ratio of gelatine/sucrose was also tested. EO was identified (confocal laser scanning microscopy and FT-IR) in all tested matrices and the release profiles, antioxidant activity and antimicrobial activity of encapsulates evaluated. Results showed that the three tested materials are able to encapsulate Oregano EO. Higher diffusion coefficients were obtained for starch microcapsules (about 10 13 m2/s) followed by spray-dried gelatine/sucrose systems (about 10 15 m2/s) and inulin microcapsules (about 10 16 m2/s). Gelatine/sucrose microparticles exhibit high antioxidant and antimicrobial activity while inulin and rice starch microencapsulates ensure higher stabilityElsevierRepositório da Universidade de LisboaBeirão-da-Costa, SaraDuarte, CláudiaBourbon, Ana I.Pinheiro, Ana C.Serra, Ana TeresaMoldao-Martins, MargaridaJanuario, IsabelVicente, António A.Delgadillo, IvoneDuarte, CatarinaBeirão-da-Costa, Maria Luísa2012-04-26T14:57:24Z20122012-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/4295eng"Journal of Food Engineering".
