PREPARATION AND PROPERTIES OF MICROFIBRILLATED CELLULOSE REINFORCED PECTIN/FENUGREEK GUM BIOCOMPOSITE

Abstract

Characteristics of Pectin and Fenugreek gum film was influenced by the incorporation of 0.01 % Microfibrillated cellulose (MFC). The tensile strength and elongation increased when compared with the blend film. The MFC films with the plant extracts (Grape seed extract, Bauhinia variegata leaf extract, and Annona Squamosa leaf extract) had lower tensile strength and elongation at break than the neat film. Solubility and water vapor permeability of the films incorporated with plant extracts noticeably decreased in comparison with the neat and blend film. They became more dark and yellow due to the presence of polyphenols and have better UV blocking property. The thermal property of the MFC films incorporated plant extracts showed low weight loss when compared with the neat film. The film with grape seed extract has the highest DPPH radical scavenging activity, compared with other plant extracts. Similar antibacterial activity was obtained in the MFC reinforced film containing the three individual plant extracts. These films were tested for packaging application by wrapping with fresh cut carrots and showed better shelf life.
