Preparation and Characterization of Cellulose Nanofiber (CNF) from Mango Peel

Abstract

Mango peel is one of agricultural waste in Malaysia. It is typically discarded after the fruit is processed, and can pose a number of environmental and agricultural issues. To solve this issue, an environmentally-safe materials such as cellulose nanofiber (CNF) can be extracted from mango peels. The acid hydrolysis method was chosen because it is a rapid method to produce CNF with a high yield, improved characteristics, and minimal processing. The objective of this study was to determine the effect of different concentrations of sulfuric acid on the yield of CNF from mango peel via acid hydrolysis and to evaluate the effect of different concentrations of sulfuric acid on the physicochemical characteristics of mango peel’s CNF.
