Natural cellulosic material characteristics: A possibility to develop antimicrobial active fiber-based packaging

Coconut husk, rubberwood sawdust, and palm leaf base are cellulosic agricultural wastes that have potential to be processed fiber as absorbing material. This study investigated characteristics (morphological, physiological properties, chemical composition, absorption capacity, water isotherms) of coconut, rubberwood, fiber. Also, the aimed develop an antimicrobial sachet packaging resist against foodborne pathogens (Listeria monocytogenes, Staphylococcus aureus, Salmonella spp., Escherichia coli) by adding lime oil (LO) emulsion or Litsea cubeba (LC) at 50 700 µL into material (1 g) before, then dried placed in 1-L seal box. Results showed among three, coconut performed best terms releasing essential (EO) bacteria. could adsorb release volatile LO LC lowest concentrations (LO, 500 µL/L; LC, 300 µL/L) inhibit bacteria compared with other fibers (700 35 °C. indicated has a low rate, which influenced faster adsorption EO beginning process; therefore, using for bacterial inhibition is possible. contains 34.5% lignin, 68.7% holocellulose, 37.6% cellulose, 31.2% hemicellulose. suitable alternative biocomposite developing new design.
