Enhancing water dispersibility of carotenoid via microencapsulation technique

Monday, April 29, 2024
5:00 PM – 6:00 PM EDT
Abstract: The solubility of carotenoid is the primary limiting factor towards its applications in food formulations. In the present study, carotenoid was encapsulated using sucrose monopalmitate, inulin and arabic gum via spray-drying. The effects of different core-to-wall ratios (1:4, 1:6, and 1:8) and spray-drying inlet temperatures (140, 160, and 180 °C) on the physicochemical properties of carotenoid microcapsules were thoroughly characterized. The lowest moisture content (4.3%) was achieved in carotenoid microcapsules formed using core-to-wall ratio of 1:8 at 180 °C. Besides, carotenoid microcapsules formed at core-to-wall ratio of 1:8 also had relatively lower bulk, tapped and particle density compared to the microcapsules formed using other core-to-wall ratios across all spray-drying inlet temperatures. Moreover, all fabricated microcapsules exhibited moderate flowability (Carr’s index: 17.03 to 23.98) and cohesiveness (Hausner ratio: 1.20 to 1.33). Furthermore, the wall materials used for encapsulation had improved the carotenoid’s solubility in water (78.12 to 83.20%). The carotenoid microcapsules produced at 160 and 180 °C had slightly higher hygroscopicity than microcapsules produced at 140 °C due to the lower moisture content. This study provided valuable insights regarding the potential of sucrose monopalmitate, inulin and arabic gum as effective encapsulating agents, as well as widened the applications of carotenoid, especially in aqueous delivery systems.
