Question

• A. Tofu
• B. Vinegar
• C. Sauerkraut
• D. Tempeh

Hint:

Fermented foods are produced by the action of microorganisms, such as bacteria or fungi, which break down food components and often enhance the food's flavor and preservation.

Answer 1

The Correct Option is A

Let's go through the options to understand which is not a fermented food: - Tofu (Option A): Tofu is made from soybeans through a coagulation process that does not involve fermentation. Tofu is produced by curdling soy milk using coagulants like magnesium chloride or calcium sulfate. Therefore, tofu is not a fermented food. - Vinegar (Option B): Vinegar is a product of fermentation. It is produced by fermenting ethanol (from wine, beer, or other sources) with acetic acid bacteria, which convert the alcohol into acetic acid. Therefore, vinegar is a fermented food. - Sauerkraut (Option C): Sauerkraut is made by fermenting cabbage with lactic acid bacteria. This is a classic example of a fermented food. The bacteria break down sugars in the cabbage, producing lactic acid that preserves the cabbage and gives it its characteristic sour taste. - Tempeh (Option D): Tempeh is a fermented food made by fermenting cooked soybeans with the fungus Rhizopus oligosporus. It is a traditional Indonesian product and is a fermented food. Thus, the food that is not fermented is Tofu. Final Answer: \[ \boxed{\text{(A) Tofu}}. \]
