tFresh industrial mango peel waste (MPW0) has to be processed into a storable commodity to enableits upgrading into dietary fibers or pectin and antioxidants regardless of its seasonal availability. In thisfeasibility study, 19 prototype processes that involved hot-air drying for stabilizing the juicy MPW0offully ripe fruit were evaluated regarding the efficiency of the drying step, the recyclable mass percentageof MPW0, and the functional quality of the dried mango peel (DMP). Depending on the process variant,hot-air drying was applied directly or after different types of peel preprocessing in order to assess theefforts needed for mechanical dewatering, the prevention of enzymatic browning by peel blanching,the control of the Maillard reaction by adjusting the drying temperature, and the removal of mesocarpfrom MPW0by blanching or pressing. As shown by principal component analysis, the process variants,which proved to be most efficient regarding drying due to included peel blanching (88◦C, 1 min), pressing(150 bar, 5 min), and cutting, also ensured optimal performance of DMP. At best, the yields and purityof extractable pectins (11.4–13.2 g hg−1with 77–83% of galacturonic acid) as well as the dietary fibercontents, the antioxidant capacity, and the technological functionality were maximal. Especially the slurryviscosity of powdered DMP (15%, w/v; 16–31 Pa s at 2.5 s−1) and the water-holding capacity (6.5–7.1 g g−1)were decisively improved, but at the expense of slurry yellowness and ˇ-carotene contents. Separation ofpuree (61 g hg−1) from MPW0by intensive pressing before peel processing into DMP (8.7 g hg−1) yieldedthe maximal amount of reusable by-products without affecting DMP functionality.
