Question

Tomato is a natural source of which acid?

Options

• Acetic acid

• Tartaric acid

• Oxalic acid

• Citric acid

Answer 1

Oxalic acid

Explanation:

Tomato is considered a significant natural source of oxalic acid. While tomatoes also contain other organic acids, such as citric acid and malic acid (which are more abundant in concentration), oxalic acid is the acid uniquely associated with tomatoes in most standard educational and competitive examination contexts. It is naturally occurring in various plants and acts as a key contributor to the tomato’s chemical profile.
