With the continuous development of social and economic levels, people's pursuit of quality of life is also advancing with the times, and modern times pay more and more attention to health preservation. As red wine, it is more popular among consumers than white wine, foreign wine, and beer. It tastes sweet and has beauty effects, and meat fins are loved by female consumers.
So how to judge the quality of wine? The traditional way is to use sight, smell and taste. Whether it is very accurate or not is affected by many factors. The modern wine production industry uses a Colorimeter to measure the color and luster of wine, and determines a relatively complete detection scheme by analyzing these data.
In the wine production process, the evaluation of color is an important indicator of its appearance quality. The oxidation degree and quality of a bottle of wine can be judged according to the chroma and hue of the wine. The chroma of the wine is mainly determined by the phenolic substances anthocyanins and tannins in the wine. The content of anthocyanins and tannins is high. The color of the wine is darker, and the chroma value is the opposite, which is relatively low. However, the various properties of the pigment are affected by the pH of the wine liquid and some reagents (such as acidic sodium sulfite), so that the color of the wine changes. These data can be quickly measured using the SanEnchi spectroColorimeter, and the chromaticity value measured by the Colorimeter can be seen that as the pH value increases, the chromaticity value also increases. In addition, the method can limit the determination of the original wine juice content, the phenomenon is obvious and intuitive, accurate and reliable. The determination method of red wine color was studied by Colorimeter. Using a Colorimeter to measure the color of red wine and conduct sensory analysis, it is found that there is a certain linear relationship between L* value (brightness variable), a* value (redness variable) and anthocyanin content and tannin in red wine relation.
The above is the application of the Colorimeter in the quality detection of red wine, hoping to provide reference for relevant staff in the industry.
