Test Your Knowledge: Tea Oxidation Quiz

Question 1: What is tea oxidation?

— Tea oxidation refers to the chemical reaction that occurs when tea leaves are exposed to air, which transforms the leaves and affects the flavor, aroma, and color of the tea.

Question 2: Which type of tea undergoes full oxidation?

— Black tea is fully oxidized, which gives it a stronger flavor and darker color compared to other types of tea.

Question 3: What is the primary enzyme involved in the oxidation of tea leaves?

— Polyphenol oxidase is the primary enzyme responsible for the oxidation process in tea leaves, leading to the development of flavor and color.

Question 4: Which tea is known for having the least oxidation?

— Green tea undergoes minimal oxidation, preserving the fresh and grassy flavors of the leaves.

Question 5: What effect does oxidation have on the flavor of tea?

— Oxidation enhances the sweetness and complexity of tea, contributing to its rich flavors and aromas.

Question 6: How does the oxidation process begin?

— The oxidation process begins when tea leaves are rolled and bruised, which damages the cells and exposes polyphenols to oxygen.

Question 7: What is the role of temperature in the oxidation of tea?

— Higher temperatures can accelerate the oxidation process, affecting the flavor and aroma of the tea.

Question 8: Which of the following teas is partially oxidized?

— Oolong tea is partially oxidized, which gives it a unique flavor profile that lies between green and black tea.

Question 9: What is the ideal humidity level for oxidizing tea leaves?

— The ideal humidity level for oxidizing tea leaves is between 40-70%, as it aids in the proper enzymatic reactions needed for oxidation.

Question 10: Why is oxidation important for the tea industry?

— Oxidation is crucial in the tea industry as it determines the final flavor, aroma, and quality of the tea, which are key factors for consumer preference.
