Among them, -carotene is regarded the most potent precursor of vitamin A. However, it is susceptible to oxidation upon exposure to oxygen, light, and heat, which can result in loss of colour, antioxidant activity, and vitamin activity.Thus, the objective of thiswork was to study themicroencapsulation process of -carotene by spray drying, using arabic gum as wall material, to protect it against adverse environmental conditions. This was carried out using the response surfacemethodology coupled to a central composite rotatable design, evaluating simultaneously the effect of drying air inlet temperature (110-200∘C) and the wall material concentration (5-35%) on the drying yield, encapsulation efficiency, loading capacity, and antioxidant activity. In addition, morphology and particles size distribution were evaluated. Scanning electron microscopy images have shown that the particles were microcapsules with a smooth surface when produced at the higher drying temperatures tested,most of them having a diameter lower than 10 m.The conditions that enabled obtaining simultaneously arabic gummicroparticles with higher -carotene content, higher encapsulation efficiency, and higher drying yield were a wall material concentration of 11.9% and a drying inlet temperature of 173∘C.The systematic approach used for the study of -carotene microencapsulation process by spray drying using arabic gum may be easily applied for other core and wall materialsHindawi Publishing CorporationRepositório da Universidade de LisboaCorrêa-Filho, Luiz C.Lourenço, Maria M.Moldao-Martins, MargaridaDelgado Alves, Vitor2019-03-07T12:23:01Z20192019-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.5/17530engInternational Journal of Food Science Volume 2019, Article ID 8914852, 12 pageshttps://doi.org/10.1155/2019/8914852info:eu-repo/semantics/openAccessreponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAP2025-03-17T16:10:56Zoai:repositorio.ulisboa.pt:10400.5/17530Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-29T04:05:05.507032Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
