Abstract

The current study aimed to investigate the effect of anthocyanins on muscle flavor compound profiles in goats. Goats in three groups were fed a basic diet or a diet supplemented with 0.5 g/d or 1 g/d anthocyanin-rich purple corn pigment (PCP). Compared to the control group, plasma total cholesterol was significantly decreased ( < 0.05) in the anthocyanin groups. The feeding of anthocyanin increased ( < 0.05) flavor compound types and total alcohol level, whereas it decreased ( < 0.05) total hydrocarbons, aromatics, esters, and miscellaneous compounds in the muscle (). Adding PCP to the diet enriched ( < 0.05) vegetal, herbaceous, grease, and fruity flavors compared to the control group. The 0.5 g/d PCP group had increased ( < 0.05) abundance of peroxisome proliferator-activated receptor gamma, but there was a decreased ( < 0.05) level of lipoprotein lipase in . Collectively, this study indicated that anthocyanin can improve mutton flavor by decreasing plasma lipid parameters and by modulating the abundance of several flavor-related genes of goats.
