Preparation of Nanocellulose Bioplastic with a Gradation Color of Red and Yellow

Abstract

Abstract A bioplastic derived from nanocellulose isolated from the pine flower (Pinus Merkusii) waste has been made. The red and yellow colors of bioplastic were afforded from the extract of dragon fruit and turmeric. Meanwhile, nanocellulose was hydrolyzed by citric acid using concentrations of 10%, 30%, and 60%, and obtained crystallinity index of 61.00%, 57.24%, and 52.82% respectively. Each nanocellulose applied has a crystallite size of 15.09 nm (calculated using XRD data with Scherrer’s equation). The result indicated that the increase in both dragon fruit and turmeric extracts concentration increase the red and yellow color intensity of the bioplastic. This study paves the way for further application of nanocellulose in bioplastic.
