喷雾干燥法制备柠檬醛微胶囊及微胶囊稳定性研究
Preparation of citral microcapsules through spray-dring and the stability of the micorcapsules
摘要
Abstract
Spray-drying and layer by layer self-assembly method were employed to prepare citral microcapsule,using methylcellulose (MC),carboxymethyl chitosan(CMCTS) and sodium alginate(Alg) as the wall materials components.The effects of wall material composition on citral content,morphology,water absorption,and stability of the citral microcapsules were investigated.The optimum wall material composition and prepare conditions were as follows:MC (in)0.8 g/50 mL H2O,CMC 1.0 g/30 mL H2O,Alg 6.0 g/180 mL H2O,MC(out)0.8 g/50 mL H2O,the citral content of citral microcapsule being 4.54％.Using amphiphilic MC as the inner wall materials improved the citral content by 3.12％.Using MC as the outer wall material increased the citral content of citral by 0.23％,reduced the water absorption of microcapsules by 0.42％ in 90 days and improved the stability of the microcapsules during storage.关键词
