Bài viết này trình bày về hạt Ca-Alginate vi bọc tinh dầu chanh bằng phương pháp ion-gel được thực hiện và sau đó ngâm trong dịch Chitosan để có hạt Ca-AlginateChitosan. Nồng độ CaCl2 tăng làm giảm sự phóng thích tinh dầu chanh. Mời các bạn cùng tham khảo! | 58 Trường Đại học Nông Lâm TP. Hồ Chí Minh Release kinetics of lime essential oil Citrus aurantifolia from beads microencapsulated through ion-gel method Vinh Truong Phuong T. Nguyen Nhung T. C. Pham amp Phuong T. Nguyen Department of Chemical Engineering Nong Lam University Ho Chi Minh City Vietnam ARTICLE INFO ABSTRACT Research Paper Ca-Alginate beads for microencapsulation of lime oil Citrus aurantifolia by ion-gel method was manufactured and then soaked in Chitosan solution Received November 15 2020 to obtain Ca-Alginate-Chitosan beads. Increased CaCl2 concentrations Revised February 12 2021 reduced lime essential oil release. The alginate concentration 2 to 3 Accepted February 23 2021 and water temperature affected significantly the release of oil P lt . The higher temperatures the higher the release rate. The oil release at Keywords 75o C was twice as much as at 45o C. At 45o C the difference in the release rate among the alginate concentrations of 2 and 3 was clear and statistically significant P lt . However at 60o C and 75o C there was Ca-Alginate no significant difference in release between the alginate concentration of Ion-gel method and 3 P gt . In the storage of beads in 1 CaCl2 solution Lime oil at normal temperature after the first 15 days Ca-Alginate-Chitosan Microencapsulation system released about 3 slower than Ca-Alginate system but there was Release kinetic no difference between the two systems after 45 days. This shows that if prolonged for a long time the ion-gelation of Ca-Alginate prevails over Corresponding author the Alginate-Chitosan cross-link. Truong Vinh Email tv@ Cited as Truong V. Nguyen P. T.
