Study on the Inhibitory Activity of Extracts from Apple Pomace against Tyrosinase

[Objective]To search for a safe and high-efficient tyrosinase inhibitor.[Method]Monitored by enzyme kinetic method,the inhibitory effect of apple pomace extracts against tyrosinase and potato browning was studied.[Result]The inhibition effect on tyrosinase was irreversible.When the extracting solution from apple pomace was at the concentration of 2.0 g/L,the inhibitory rate against tyrosinase was 90.0% and that against potato browning was 86.8%.[Conclusion]The inhibitory effect of apple pomace extracts against tyrosinase has paved a new path for the anti-browning of fruits and vegetables,thus it has great development value.
