None of the above
While tea processing involves an oxidation step often referred to as "fermentation," it's technically not a true fermentation process.
• Here's why:
-Oxidation, not Fermentation: True fermentation involves the breakdown of sugars by microorganisms in the absence of oxygen (anaerobic conditions). In tea processing, the leaves are exposed to air, allowing enzymes within the leaves to oxidize polyphenols, which leads to the development of characteristic color, aroma, and flavor compounds.
✏Types of Tea: The degree of oxidation determines the type of tea:
-Black Tea: Fully oxidized.
-Oolong Tea: Partially oxidized.
-Green Tea: Minimally oxidized.
-White Tea: Un oxidized.
📌 Other Options Explanations:
-Alcoholic Fermentation: Involves the conversion of sugars to alcohol and carbon dioxide by yeast. This is used in making beer, wine, and bread.
-Non-alcoholic Fermentation: Can involve the production of lactic acid (as in yogurt and sauerkraut) or other organic acids.
-Acetic Fermentation: Involves the conversion of alcohol to acetic acid by bacteria. This is used in making vinegar.
