Mangiferin production from mango agro-industrial waste

Brazil is the seventh largest mango producer in the world [1]. During the mango juice production, agro- industrial residues represent around 20 – 40% v/v and are mainly made up of peels and almonds [2]. The main chemical constituents of the peels are phenolic compounds, natural pigments and biopolymers. Several biological activities have been attributed to the substances present in mango peels, however, only initiatives of low economic value have been used for the use of this residue [3]. Hence, the aim of this work was to obtain phytochemicals using mango peel residue (M. indica "Tommy Atkins") obtained from 2 different seasons. The samples were analysed by LC-DAD-MS and the main compound identified was mangiferin. After pulping, the peels were stored at room temperature and the mangiferin content was determined right after the pulping (T0), after 6 hours (T1) and after 24 hours (T2). The mangiferin content in different batches ranged from 0.04 – 0.14% w/w at T0. Mangiferin content significantly dropped at T2, indicating that after pulping, the peels must be extracted after at least 6 hours when stored at room temperature. Mango peels are a valuable resource for mangiferin production.
