Simple Antimicrobial Labels from Cinnamon Oil Added to Recycled Paper

Abstract

: Essential oils are one of the antimicrobial agents that are safe for food, and thus can be used as an antimicrobial label to extend the shelf life of food products. This study aims to prepare antimicrobial labels and to investigate their activities in shrimp. Antimicrobial labels are made using cinnamon oil in the recycled paper as a simple matrix. Cinnamon oil was tested on Gram-positive Staphylococcus aureus and Gram-negative bacteria Escherichia coli using the paper disk diffusion method. From the results obtained, cinnamon oil has both antimicrobial activities. Cinnamon oil is also characterized using Gas Chromatography-Mass Spectrometry (GC-MS) to determine the level and presence of compounds suspected of having antimicrobial activity. Cinnamon oil has interactions with recycled paper functional groups as measured by Fourier Transform Infrared Spectroscopy (FTIR). Testing of antimicrobial labels on shrimp shows that the Total Volatile Basic Nitrogen (TVB-N) value is better than without the label. From the results of antimicrobial activity, can be seen that cinnamon oil applied to recycled paper has the potential to be used as a simple antimicrobial label.
