Effect of the procyanidins of acrylamide inhibition in glucose-asparagine model system

Procyanidin of litchi pericarp ( LPPC) and procyanidin of lotus seedpod ( LSPC) was chosen to study the inhibition of acrylamide in the model system. The result showed that two kinds of procyanidins concentration-inhibition rate relationships were nonlinear changes.Acrylamide inhibition rate reached the maximum of 53.01% ± 5.62% and 76.60% ± 3.20%, when the add amount of LPPC and LSPC were 0.5 mg·m L-1and 0.1 mg·m L-1. At the same time, the relationship between antioxidant systems, color and black fine class content and inhibition rate was also discussed. The stronger the antioxidant activity and whiteness of antioxidant systems, the better the acrylamide inhibition rate. In contrast, the higher the content of melanoidin, while the lower the inhibition rate of crylamide.It can be concluded that procyanidine significantly decreased the incidence of acrylamide.
