以冬枣中常见致病菌青霉（Penicillium sp.）和黑曲霉（Aspergillus niger）为控制对象，通过单因素和正交试验研究不同复配比、不同处理温度和pH条件下肉桂精油和紫苏精油对这两种霉菌的抑制效果。结果表明：（1）肉桂精油对青霉和黑曲霉的最小抑菌浓度（MIC）分别为：0.313μL/mL和0.156μL/mL；紫苏精油对青霉和黑曲霉的MIC分别是10μL/mL和5μL/mL；（2）肉桂精油与紫苏精油在总含量为0.42μL/mL，复配比为3∶1，处理温度为5℃和pH为3时抑菌效果最好，对青霉和黑曲霉的最大抑菌圈直径可高达24 mm和22.7 mm。说明复配精油对青霉和黑曲霉均有明显的抑制作用，是一种良好的冬枣贮藏霉菌抑制剂。

Penicillium sp.and Aspergillus niger were isolated from red dates as the tested strains. Through determination of cinnamon oil and perilla oil in different scale, different temperature and different pH conditions, study on inhibition of the two fungi, and on the basis of orthogonal test optimization to determine the optimum inhibited conditions. The test results show that:cinnamon oil to Penicillium sp. minimum inhibitory concentration (MIC) is 0.313μL/mL, Aspergillus niger MIC is 0.156μL/mL, and perilla oil on Penicillium sp. and Aspergillus niger MIC are 10 μL/mL and 5 μL/mL;cinnamon oil and perilla oil in the total content of 0.42 μL/mL, two concentration ratio was 3 ∶ 1, 5 ℃, pH 3 on Penicillium sp. antibacterial circle diameter up to 24 mm, on Aspergillus niger antibacterial circle diameter up to 22.7 mm. The composite essential oils of cinnamon and perilla which has obvious inhibiting effect on Penicillium sp. and Aspergillus niger, is a good storage of Dongzao jujube mildew inhibitor.
