Quality attributes of mixed fruits leather prepared from mango, pineapple and papaya pulp

Abstract

Four different formulated mixed fruits leathers from mango, pineapple and papaya pulp were prepared by cabinet drying method. The present study was aimed to evaluate the proximate and physicochemical properties of those formulated leathers. The total soluble solid (TSS) was higher in mango pulp. Although the moisture content of fruit pulp was around 80%, it was reduced until 10-15% in the dried leather. The amount of fat content was very negligible in the prepared leathers. However, high amount of crude fiber (6%) was found in all the samples. The reducing sugar in the sample was around 11%. As no other preservative was used except a small amount of sodium benzoate, so the fungal test was positive for all the samples. However, the formulated leathers by changing the fruit ratio did not influence hugely on moisture content, ash content and other proximate compositions. Therefore, all the four types of mineral rich formulated leathers could be consumed depending on the preference of consumers' taste. The simple and cost-effective leather could be an effective way to reduce post-harvest losses of ripe fruits.
