What does the process of oxidation involve?

The process of oxidation involves substances picking up oxygen and undergoing chemical reactions. This phenomenon is significant in both culinary and nutritional contexts. When a substance oxidizes, it typically reacts with oxygen in the air, leading to various chemical changes that can affect flavor, color, and nutritional value.

For instance, in the context of fruits, when they are exposed to air, oxidation can cause them to brown due to the reaction of enzymes with oxygen, which can alter their taste and aesthetic appeal. In fats, oxidation can lead to rancidity, which negatively impacts flavor and safety. Thus, understanding oxidation is crucial for food preparation, preservation, and nutrition as it influences the quality and shelf life of food products.
