Sample interview questions: Can you explain your knowledge of the chemical reactions involved in food enzymatic reactions?
Sample answer:
Chemical Reactions in Food Enzymatic Reactions
Enzymatic reactions play a crucial role in various aspects of food chemistry, from food processing to quality control. These reactions involve the action of enzymes, which are protein catalysts that facilitate specific chemical transformations in food.
-
Hydrolysis: This reaction involves the cleavage of chemical bonds between two molecules by the addition of water molecules. It is catalyzed by hydrolytic enzymes such as amylases, lipases, and proteases. Hydrolysis reactions are essential for breaking down complex carbohydrates, lipids, and proteins into simpler components, making them more digestible and available for absorption.
-
Oxidation: In food chemistry, oxidation involves the addition of oxygen to food components, which can lead to browning reactions and the development of off-flavors. Enzymatic oxidation reactions are catalyzed by enzymes such as polyphenol oxidases and lipoxygenases. They play a role in the browning of fruits and vegetables, as well as the development of rancidity in fats and oils.
-
Reduction: This reaction involves the removal of oxygen or other electron-withdrawing groups from molecules and is catalyzed by enzymes such as reductases. Reduction reactions are important in food preservation and processing,… Read full answer
