Abstract

Chitosan oligosaccharide, chitosan polysaccharide and monolaurin were used to impart the antimicrobial properties onto paper for food products . Staphylococcus aureus (ATCC 25923) was used as test microorganism and shake flask test was carried out in order to examine the antimicrobial activity of each sample. Chitosan oligosaccaride showed the greatest antimicrobial effect among them and gave the promising result even at the concentration of 0.005%. Its antimicrobial power was enhanced when it is used with nomolaurin together. Chitosan oligosaccharide improved the tensile strength of antimicrobial paper.
