Description

Technical Field

[0001] This utility model relates to the field of wine testing technology, specifically to a device for detecting volatile flavor components in wine. Background Technology

[0002] Wine is an alcoholic beverage made from grapes or grape juice through complete or partial alcoholic fermentation. It belongs to the category of fermented wines and is widely enjoyed. Volatile flavor compounds are one of the important indicators for evaluating wine quality and are also a typical characteristic of wine. Studying the volatile flavor compounds before and after fermentation allows us to understand their changes. Currently, volatile flavor components in wine are generally detected using gas chromatography (GC). GC utilizes the different adsorption and desorption capacities of different flavor compounds in a gas chromatographic column to achieve separation. This method is suitable for analyzing volatile flavor compounds such as alcohols, esters, and aldehydes. Its advantages include high sensitivity, good separation effect, and accurate quantitative analysis.

[0003] When detecting volatile flavor components in wine, a certain amount of wine sample needs to be accurately measured, an appropriate amount of diluent (such as distilled water) needs to be added, and the sample needs to be shaken well before gas chromatography analysis. However, the measurement of wine sample and the addition of diluent are usually done manually by pouring the sample directly into the container. The measurement and ratio are prone to inaccuracy, and it is inconvenient to shake the sample well quickly, which will affect the accuracy of the detection results. Therefore, we propose a detection device for volatile flavor components in wine. Utility Model Content
