- Abstract: OBJECTIVE: To investigate the color and chemical composition of the wax slices, w-powder slices, r-powder slices, blood slices and bone slices of two-branch Velvet Antler, three-branch Velvet Antler and reborn Velvet Antler with different growth years, and analyze the relationship between the color characteristics and chemical composition (protein, polysaccharide, phospholipid). METHODS: The color parameters of five kinds of slices with different growth periods were detected by CIEL*a*b* color space. The content of protein was determined by Coomassie blue colorimetric method, the content of polysaccharide was determined by phenol sulfuric acid method, and the content of phospholipid was determined by molybdenum blue colorimetric method. Pearson correlation analysis was used to analyze the correlation between color and components. RESULTS: There were significant differences in color and chemical composition between the five types of Velvet Antlers with different grow periods. Pearson correlation analysis showed that the Velvet Antler color parameter b* had a significant negative correlation with the three chemical components. CONCLUSION: The color determination method based on the principle of colorimetry can effectively distinguish Velvet Antlers in different growth stages. And the correlation analysis showed that the color digital index can reflect the difference in chemical composition of Velvet Antler in a certain degree.
