Extraction of dietary fiber and polyphenols from mango peel and its therapeutic potential to improve gut health

Mango peel is an important agro-industrial waste that has high levels of polyphenols and dietary fiber. There is an obvious shortage of product variety in the food sector, making research into new product creation even more important. Nowadays, only mango pulp is utilized in commercial items, resulting in the loss of the fruit's other components, which contain important chemicals. Numerous investigations on the extraction of bioactive components from mango peel have been undertaken, covering both classic techniques (direct boiling, solvent macerating, distillation, and compression) and green extraction technology (ultrasound-assisted, enzymeassisted, and ultrasound-assisted enzyme technique). Several approaches may be used to extract carotenoids, dietary fiber, and phenolic compounds. Dietary fiber and polyphenol intake have been linked to improved gut health. Polyphenol bioactivity and the risk of metabolic disorders may be affected by gut microbiota. The gut microbiota is vital for human health because it affects many host defensive mechanisms by enhancing antioxidant activity, tripling lactic acid bacteria, and assisting in the production of a superior prebiotic product. This review provides an overview of the high-quality extraction of dietary fiber and polyphenols from mango peel and also the interactions of these dietary compounds with gut microflora and associated health benefits and underlying mechanisms.
