Solvent, Enzymatic, and Ultrasonic Extraction of Date Phenolic Compounds
摘要
This chapter discusses various extraction techniques for isolating phenolic compounds from date fruits, which are known for their antioxidant properties and health benefits. The chapter highlights three primary methods of extraction: solvent extraction, enzymatic extraction, and ultrasonic extraction. Solvent extraction involves using organic solvents to dissolve and separate phenolic compounds, while enzymatic extraction utilizes specific enzymes to break down cell wall structures, enhancing the release of these compounds. Ultrasonic extraction leverages high-frequency sound waves to improve solvent penetration and increase the efficiency of phenolic compound extraction. The chapter evaluates the effectiveness, recovery rates, and synergistic effects of these methods, comparing their advantages and limitations. Additionally, it addresses factors influencing extraction efficiency, such as temperature, time, and solvent type. The findings underscore the importance of selecting appropriate extraction techniques to maximize the yield and quality of phenolic compounds from dates, contributing to their application in food, nutraceuticals, and cosmetic industries.
