不同包装容器对劲酒品质的影响

目的 研究包装容器对酒体品质的影响因素，为劲酒包装容器的选择提供科学的数据支撑。方法 采用光学透过率测试仪对不同包装容器的透光率进行了测定，并对贮存2年的劲酒的总黄酮含量、总皂苷含量、色率、淫羊藿苷含量、口感进行分析，数据分析的方法为随机区组设计资料的方差分析。结果 无色玻璃瓶、PET瓶透光率高达90%以上，深色瓶、涂漆瓶、陶瓷瓶、不锈钢瓶透光率均极小。总体来说高硼硅玻璃瓶和PET瓶储存的劲酒均有不同程度的颜色变浅，总黄酮、总皂苷含量降低，口感变差，其他容器储存的酒体之间没有明显差异，且它的总体品质要高于高硼硅玻璃瓶和PET瓶储存酒体的总体品质。结论 包装容器的透光性会对劲酒的品质产生影响，避光包装容器可能更适合劲酒的储存，避光容器的材质和形状对劲酒品质基本没有影响;对于透光性容器，容器形状可能影响劲酒品质，相较于圆柱型的包装容器，扁平型的可能更能保护劲酒品质。

Effect of Different Packaging Containers on Quality of Jingjiu

The work aims to provide scientific data support for the selection of packaging containers for Jingjiu from the perspective of the impact on liquor quality. The light transmittance of different packaging containers was measured with an optical transmittance tester. The total flavonoids, total saponins, color rate, icariin and taste of stored Jingjiu for 2 years were analyzed, and variance analysis of random block design data was used as the method of analyzing data. The light transmittance of colorless glass bottles and PET bottles was as high as 90% or more. The light transmittance of dark bottles, painted bottles, ceramic bottles, and stainless steel bottles were all extremely small. On the whole, Jingjiu stored in high borosilicate glass bottles and PET bottles had varying degrees of lighter color, lower total flavonoids and total saponins as well as worse taste. There was no obvious difference between the liquors stored in other containers, and the overall quality was better than those stored in high borosilicate glass bottles and PET bottles. The light transmittance of the packaging container will affect the quality of Jingjiu, and light-proof packaging containers may be more suitable for storing Jingjiu. The material and shape of the light-proof container basically have no effect on the quality of Jingjiu. For light-transmitting containers, the shape of the container may also affect the quality of Jingjiu. Compared with the cylindrical packaging container, the flat type may better protect the quality of Jingjiu.
