Answer key with explanations
The correct answers, each one explained. Open any question to check it.
1 What is tea oxidation?
Correct answer: B) The chemical reaction that occurs when tea leaves are exposed to air.
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.
2 Which type of tea undergoes full oxidation?
Correct answer: D) Black tea
Black tea is fully oxidized, which gives it a stronger flavor and darker color compared to other types of tea.
3 What is the primary enzyme involved in the oxidation of tea leaves?
Correct answer: A) Polyphenol oxidase
Polyphenol oxidase is the primary enzyme responsible for the oxidation process in tea leaves, leading to the development of flavor and color.
4 Which tea is known for having the least oxidation?
Correct answer: A) Green tea
Green tea undergoes minimal oxidation, preserving the fresh and grassy flavors of the leaves.
5 What effect does oxidation have on the flavor of tea?
Correct answer: B) It enhances the sweetness and complexity.
Oxidation enhances the sweetness and complexity of tea, contributing to its rich flavors and aromas.
6 How does the oxidation process begin?
Correct answer: B) When tea leaves are rolled and bruised.
The oxidation process begins when tea leaves are rolled and bruised, which damages the cells and exposes polyphenols to oxygen.
7 What is the role of temperature in the oxidation of tea?
Correct answer: A) Higher temperatures speed up oxidation.
Higher temperatures can accelerate the oxidation process, affecting the flavor and aroma of the tea.
8 Which of the following teas is partially oxidized?
Correct answer: C) Oolong tea
Oolong tea is partially oxidized, which gives it a unique flavor profile that lies between green and black tea.
9 What is the ideal humidity level for oxidizing tea leaves?
Correct answer: B) 40-70%
The ideal humidity level for oxidizing tea leaves is between 40-70%, as it aids in the proper enzymatic reactions needed for oxidation.
10 Why is oxidation important for the tea industry?
Correct answer: B) It determines the final flavor and quality of the tea.
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.
