  • This study was carried out to manufacture microcapsules from natural aromatic essential oils by polymeric emulsification and to evaluate their properties using microscopical and electro-chemical analysis techniques. It was shown that aromatic essential oils (yuja, lavender, and peppermint) could be microcapsulated and their emulsion has a good stability and storage characteristics.

  • Crosslinked corn starches were prepared to increase their molecular weights and their performance as a component of Compozil system was evaluated and compared with that of potato starches. It was shown that greater improvements in retention and strength properties could be achieved when crosslinded cationic corn starches rather than conventional cationic potato starches were used especially at high conductivity because of their molecular rigidity.

  • 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.
