Recent Advances in Extraction of Polyphenols by Advanced Extraction Methods

Polyphenols are the plant-derived chemicals that have antioxidant properties and provide a wide range of health applications. Traditional polyphenol extraction techniques are limited in scalability, efficiency, and environmental effect. To address these constraints, various advanced approaches came into existence, like ultrasound-assisted extraction, microwave-assisted extraction, and supercritical fluid extraction. These sophisticated approaches come with several benefits over traditional extraction approaches. These advanced extraction methods are more efficient, use very low amounts of solvents, and have minimal environmental effect. These techniques can retain the integrity of bioactive chemicals and are suitable for large-scale extraction, too. Polyphenol-rich extracts have a wide range of uses. They can be utilized as ingredients or additives in foods, cosmetics, and coatings and packing materials. The advancement of these new techniques will be critical for the future polyphenol extraction with an emphasis on sustainability-related factors. These approaches have the potential to address the growing demand for polyphenols while also helping to create more efficient and sustainable extraction procedures.
