DEMYSTIFYING FOOD BROWNING: FROM APPLE DISCOLORATION TO CARAMELIZED DELIGHTS
Description
Browning is a crucial process in food chemistry that affects the processing methods used in food products. It can be divided into enzymatic and non-enzymatic browning, which can impact nutrition, technology, and financial costs. Enzymatic browning occurs in fruits, vegetables, seafood, and meat, producing melanin from natural phenol through poly-phenol oxidase (PPO) and other enzymes. This process results in the formation of brown pigments on the food's surface. Research on enzymatic browning focuses on blocking poly-phenol oxidase activity. Non-enzymatic browning, such as the Maillard reaction and caramelization, also results in browning in food. Caramelization involves the pyrolysis of sugar to create a nutty flavor and brown color, while the Maillard reaction creates artificial flavors for processed foods. The results of these reactions may vary depending on the process and chemicals involved, making it essential for researchers and food technologists to identify the perfect ratio and process for food production.
