Coating of the paper
surface against to microorganism to making it suitable for food packaging is
crucial in terms of improving antimicrobial properties. Cuminum cyminum L. known as cumin and Prunus mahaleb L. have the abundant chemical compound. Cumin has
antiviral activity that making it proper for coating due to its various
components. Mahaleb as well has rich fragrance make it eligible for sugary
snacks and chocolate package. After coating with such biomaterials, thanks to
varied fatty acids impart protective feature from oxidation to paper surface.
It was observed that the odor of substances was trapped from paper samples.
Wrapping paper selected as a base paper in this study. Cationic starch used for
emulsifying the coating chemical. Cumin and mahaleb added the starch emulsion
and coating suspension applied on the top pile of the paper with # 0 drawdown
bar. Coating application reduced the paper's tear index results but increase
tensile and burst index results in both cases. Mahaleb gives better Cobb60
value and bursting and tensile index and comparing to Cumin. However, cumin
coated papers tensile index results in machine direction was better than
mahaleb. Both natural substances are suitable material as an additive to the
coating.
