Agro-industrial potential of the mango peel based on its nutritional and functional properties

Abstract

The mango peel represents from 15% to 20% of the total weight of the fruit. The aim of this review is to discuss the nutritional, functional, and nutraceutical properties of mango peel. It also shows several ways to add value to the mango peels, and their uses. Mango peel contains considerable content of antioxidants and dietary fiber. The mango peel offers a range of possibilities to develop value-added products. By-products from the agro-industrial processing of mangos can potentially make a significant contribution to the design of natural products rich in dietary fiber for widespread consumption. Additionally, food rich in soluble dietary fiber from mango peels could be designed for diabetic persons, since the mango peel reduces the speed with which glucose reaches the blood. Optimal extraction methods and drying technologies that do not impair the functional properties need to be further investigated. Economic, nutritional, and environmental benefits could be obtained with the proper use of this processing by-product.
