Different glass bottles of its chemical composition difference is bigger also, the bottle of many components in the process of holding liquor will more or less dissolved in wine, these into group branch affect the taste of wine in wine Color indicator Liquor, therefore, the physical and chemical properties of glass bottles on the loading has a potential influence the quality of liquor.
The glass bottles commonly used by liquor enterprises are mainly transparent and translucent.Nowadays, the popular translucent bottle is mainly opalescent glass. A certain amount of fluoride phosphate and other opalescent agent has been added to the compound material. The micro-grains precipitated by opalescent agent when the glass liquid is cooled are different from the refractive index of the main glass, which makes the glass opalescent under the action of light diffusion.
The experiment proved that the free water in the wine will react with some components in the wine bottle when the wine bottle is filled with white wine, so that a small amount of components in the wine bottle will be dissolved into the wine bottle.For example, a trace amount of K+ dissolved into liquor can increase the taste of the aged alcohol in the liquor; The dissolution of Na+ makes the aroma of the wine worse and less clean, which has a negative effect on the taste of the wine. The increase of Al3+ will make the wine quality deteriorate and the wine body will appear light and astringent. However, the effects of Ca2+ on different quality wines were not the same.
To this end, in the selection of wine with glass packaging bottles, should avoid the use of wine bottles containing harmful heavy metal plasma, to avoid possible harm to the body of consumers; The wine bottle with high SiO2 content and low Na2O content should be selected as far as possible. If the wine bottle is properly treated with water in advance, it can effectively reduce the influence of the composition of the wine bottle on the quality of the liquor it contains to a certain extent.
