Abstract
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.
