摘  要:
利用微乳化技术,构建以肉桂精油为油相的食品级微乳体系,研究乙醇和丙酸作为助乳化剂对肉桂精油微乳体系相行为的影响,观察微乳液单独或结合壳聚糖对灰葡萄孢的抑菌效果。通过比较微乳区大小,选取配方为肉桂精油、乙醇、吐温-80质量比为1:3:6进行抑菌效果研究。在体外实验中,肉桂精油微乳液对灰葡萄孢的最低杀菌量(MFC)为250μL/L;在体内实验中,1g/L壳聚糖能提高500μL/L肉桂精油微乳液的抑菌效果,第4天时仍能完全抑制灰葡萄孢的生长,苹果灰霉病的防治率为100%。

摘  要:
In this work,a food-grade microemulsion system with cinnamon essential oil(CEO) was established,and the effects of ethanol and propionic acid on the phase behavior of the microemulsion were explored.The antimicrobial activity of the microemulsion alone or in combination with chitosan against Botrytis cinerea was also studied.The solubility of the oil was improved in the presence of ethanol and propionic acid.The formulation of CEO,ethanol and Tween-80 in a mass ratio of 1:3:6 was selected for antimicrobial assay.The minimum fungicidal concentration(MFC) of the microemulsion against B.cinerea was 250 μL/L in vitro.The microemulsion at 500 μL/L,in combination with 1 g/L chitosan,showed a complete inhibitory effect on gray mold in apples caused by B.cinerea after 4 days of storage.
