Commercial leather production involves passing the puree through a mechanical finisher with a stainless steel sieve.
Mango leather has 15-20 % moisture. Drying at higher temperatures results in a darker colored final product and hence a lower sensory quality.
Mango leather is normally sold in the form of a roll, with grease-proof paper between layers to avoid it sticking together.
The dried product develops a leathery consistency, is rolled and cut into desirable sizes.
The fruit leather has a shelf life of about 8 months when stored at 24-30° C.
