Abstract

As a natural bioactive compound, tea polyphenols hold significant importance in food processing and preservation, demonstrating considerable application potential. Their oxidative polymerization process directly impacts product quality, stability, and functional characteristics. Citric acid, a commonly used acidity regulator and color stabilizer in the food industry, can influence the oxidative polymerization of tea polyphenols through multiple pathways. Clarifying its kinetic regulation mechanism is crucial for optimizing processing techniques and enhancing product quality in both theoretical and practical aspects. This study systematically analyzes the environmental effects of citric acid on the oxidative polymerization of tea polyphenols, explores the regulatory patterns of key kinetic parameters, and reveals molecular-level control principles. Based on these findings, the paper proposes process optimization strategies tailored to kinetic characteristics, providing theoretical foundations for precise control of the oxidative polymerization process and efficient retention of active components. The research focuses on core themes, combining theoretical depth with practical guidance, offering novel approaches and methodologies for food-related studies and production practices.
