Papaya for soup can be bought in the vegetable market, and papaya for fruit can be bought in the fruit market.

Papaya fresh fruit contains more tannins and organic acids, and its sugar content is relatively low, so it is sour and not suitable for raw food. But its fruit is rich in nutrients and vitamins. The acidic components in papaya include malic acid, citric acid and tartaric acid. These organic acids have pure sour taste, and can be made into products with unique flavor after proper dilution and supplemented with certain sweeteners such as sucrose or honey.
