What effect does cooking sometimes have on the concentration of polyphenols in quince compared to Vitamin C?

Answer

The cooking process can increase the bioavailability or concentration of certain bound phenolic compounds.

While high heat may degrade some heat-sensitive vitamins like Vitamin C, the preparation of quince often enhances the body's ability to absorb certain bound polyphenols, representing a favorable trade-off.
