A complex polysaccharide generated from plants, pectin is essential for food, medicine, and pharmaceutical applications because of its gelling, stabilizing, and health-promoting qualities. Conventional pectin extraction, which has historically been done from apple pomace and citrus peels using hot acid solutions, has several drawbacks, including high energy consumption, lengthy processing periods, and environmental issues related to strong mineral acids. In response, cutting-edge "green" methods that provide increased yields, shorter extraction times, and better functional quality--ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), and enzyme-assisted extraction (EAE)--have surfaced. In order to improve solvent penetration and mass transfer while reducing heat degradation, UAE uses acoustic cavitation to break down plant cell walls. MAE speeds up pectin solubilization, cell rupture, and diffusion by using fast, selective heating via dielectric interactions. By using particular hydrolytic enzymes to dissolve structural barriers, EAE provides customized control over the molecular weight and esterification level. In addition to analyzing extraction mechanisms, important parameters, benefits, drawbacks, and new research advancements, this review compares standard and non-traditional approaches. Process optimization, environmental sustainability, and the possibility of combining these methods to produce pectin in an effective, environmentally responsible, and superior manner are highlighted.
