Abstract
The aim of this study was to investigate the phenolic composition of a natural food colourant (G8000™) as well as its effects on plasma markers after 28-day consumption by healthy individuals at a dietary dose (70 g). Parameters of total cholesterol and its fractions, triglycerides and plasma enzymes biomarkers of muscle injury were measured. Major compounds identified in G8000™ by ESI-MS showed the presence of anthocyanins, organic acids, phenolic acids as well as monosaccharides. HDL levels significantly increased from 43 ± 10.2 mg/dL to 95 ± 16.9 mg/dL. LDL levels significantly decreased from 110 ± 40.9 mg/dL to 69 ± 39 mg/dL (p < 0.001). No significant statistical differences (p > 0.05) were observed for total cholesterol, triglycerides and VLDL. After the intake, plasma enzyme CK-MB decreased from 20 ± 12.1 U/L to 10 ± 1.9 U/L while LDH levels increased from 275 ± 124.4 U/L to 317 ± 114.7 U/L (p < 0.005). No significant differences were observed for CK levels. Taken together, dietary intake of natural colourant G8000™ was able to exert beneficial effects on atherosclerosis biomarkers.
