Caftaric acid is widely utilized in the food and beverage industry, particularly in winemaking, where it plays a crucial role in influencing the color stability and sensory properties of wines. It acts as an antioxidant, helping to preserve the quality and extend the shelf life of wines by preventing oxidation. Additionally, caftaric acid is studied for its potential health benefits, including its antioxidant and anti-inflammatory properties, making it a subject of interest in the development of functional foods and dietary supplements. Its presence in grape-derived products also contributes to the overall polyphenolic content, which is associated with various health-promoting effects.
