Natural and Synthetic Tyrosinase Inhibitors as Antibrowning Agents: An Update
Tyrosinase (EC 220.127.116.11), a copper-containing enzyme, can cause enzymatic browning in raw fruits, vegetables, and beverages. Browning is an undesirable reaction that is responsible for less attractive appearance and loss in nutritional quality. These phenomena have encouraged researchers to seek new potent tyrosinase inhibitors for use in the food industry. This article reviews recent studies on tyrosinase inhibitors of natural and synthetic origins. The information offered here should help food industry in developing and using potential tyrosinase inhibitors desirable efficacy and safety, and for improving food quality.
