Improvement of Naturally Derived Food Colorant Performance with Efficient Pyranoanthocyanin Formation from <i>Sambucus nigra</i> Anthocyanins Using Caffeic Acid and Heat

Consumers and regulations encourage the use of naturally derived food colorants. Anthocyanins (ACN), plant pigments, are unstable in foods. In aged red wines, ACN with a free hydroxyl group at C-5 condenses to form pyranoanthocyanins (PACN), which are more stable but form inefficiently. This study a...
