赤霞珠葡萄酒颜色相关物质分析及可视化表征
Analysis and visualization of color-related substances in Cabernet Sauvignon wines
摘要
Abstract
Ten samples of Cabernet Sauvignon from the northern foot of the Tianshan Mountains in Xinjiang were selected from the end of the alcoholic fermentation to the final color decline(deep purplish red to yellowish brown).The basic physical and chemical inde-xes,CIELab parameters,polyphenol content,total pigment,polymeric pigment,and other indexes of wine were determined.Pearson cor-relation analyses were performed on them.Screening of samples for characteristic indicators based on the presence of correlation using par-tial least squares-discriminant analysis.Ultimately,the visual representation is used to visualize the color of the wine and the relative con-tent of the characteristics.The results showed a correlation between basic physicochemical indicators,polyphenol content,and CIELab pa-rameters.Partial least squares-discriminant analysis,CIELab color space characterization,and two-dimensional greyscale maps showed that the main characteristic indicators of the wine body when it was purplish-red in color were L*(57.97-81.21),tannin content(4 322.66-4 385.43 mg/L).When the wine was carmine red in color,the main characteristic indicators of the wine were a*(14.69-16.41),total phenol content(2 157.59-2 983.46 mg/L),and tannin content(3 302.57-3 459.51 mg/L).When the wine was ruby red in color,the main characteristic indicators of the wine were a*(18.13-20.52),malic acid content(1.10-1.40 g/L),and tannin content(4 558.06-4 652.22 mg/L).When the wine showed a brick red color,the main characteristic indexes of the wine were tannin content(4 762.08-5 185.81 mg/L)and total phenol content(3 568.87-3 809.33 mg/L).When the total phenol content was below 2 000 mg/L,the wine was severely yellowed and no longer suitable for aging.This method directly reflects the color and characteristic in-dex information of Cabernet Sauvignon wines with different colors,and can well identify and distinguish Cabernet Sauvignon wines with dif-ferent colors.It lays a foundation for the construction of a different color Cabernet Sauvignon wine evaluation system in the northern foot of the Tianshan Mountains in Xinjiang.关键词
