Properties and Curing of Ginger Volatile Oil Microcapsules
摘要
Abstract
The preparation of ginger volatile oil microcapsules using gelatin/sodium alginate polyelectrolyte complexwas investigated.The study of the capsule and the stability of microcapsules indicated that the best curing agent is calcium chlo-ride.Scanning electron microscopy(SEM)indicated that the ginger volatile oil microcapsules were spherical and full.The encapsulation efficiency of ginger volatile oil microcapsules was(68.22±2.26)%,.The oil loading rate was(36.74±1.76)%, and the average particle size was 187.6,μm.Thermogravimetric Analysis(TGA)showed that ginger volatile oil microcap-sules exhibited higher thermal stability than ginger volatile oil,and thus resulted in less weight loss.The release study in vitro indicated that the cumulative release rate of ginger volatile oil from microcapsules was much higher when pH was 6.8(44.09%)than when pH was 1.2(36.80%).关键词
