                 粒径分布、休止角、过氧化值(POV)和 TG 结果表明,茶油微胶囊结构完整、粒径均一且具有良好的流动性、
                 分散性、热稳定性和抗氧化性。体外缓释数据表明,茶油微胶囊在模拟胃液和肠液中的缓释机理均符合
                 Ritger-Peppas 缓释模型,符合人体消化吸收特性。茶油微胶囊化保护茶油的有效成分,扩展其使用范围,提高

                 Abstract: To increase the storage stability of camellia seed oil, camellia oil microcapsules were obtained by
                 the complex coacervation method with whey protein isolate (WPI) and gum arabic (GA) as composite wall
                 materials, and transglutaminase as curing agent. Firstly, the optimal complex coacervation parameters of
                 wall material  were  determined  by  single factor experiment  using agglomerate rate as evaluation index.
                 Secondly, the optimal preparation conditions of camellia oil microcapsules were obtained by single factor
                 experiments and response surface experiment using morphology and embedding rate of microcapsule as
                 evaluation indexes. The optimum reaction conditions were as follows: mass fraction of wall materials 2.0%
                 [based  on the total  mass of the mixture,  m(WPI)∶m(GA)=1∶1],  m(core material)∶m(wall material)=
                 0.84∶1.00, pH of complex coacervation 4.3, temperature of complex coacervation 40  ℃, stirring speed
                 500  r/min. Under those conditions,  the embedding  rate  reached 89.67%.  FTIR, SEM, particle  size
                 distribution, angle of repose, POV value and TG results showed that the prepared camellia oil microcapsules
                 had good structural integrity, particle size uniformity, fluidity, dispersibility, thermal stability and oxidation
                 resistance. The sustained release data in vitro indicated that the slow-release  mechanism of camellia oil
                 microcapsules in both simulated gastric and intestinal juice were Ritger-Peppas releasing model, which is in
