The defining characteristics of Gouda cheese are its yellow color, great aroma and taste of caramel sweetness. The cheese should be well chilled before waxing, to get better seal. The seal is very important to prevent contamination with molds and putrefactive bacteria. Cheese wax is made from paraffin with additional microcrystalline to make pliable for better seal. The aim of this study was to investigate antibacterial effects of Gouda cheese wax. Methods: Gouda cheese wax samples were collected from four different manufacturers in Iran. The total count of coliforms, Escherichia coli, Salmonella, coagulase-positive Staphylococcus and mold and yeast on the samples was determined. The antimicrobial activities of Gouda cheese wax against E. coli, S. aureus, Saccharomyces cerevisiae, Aspergillus brazilissis and Salmonella enterica were investigated by determining minimum bactericidal concentration and minimum inhibitory concentration. Results: The results indicated that all Gouda cheese wax samples were prepared in accordance with the national standards. In addition, the examined wax samples had no antimicrobial properties against the tested microorganisms. Conclusions: The wax used in production of Gouda cheese in Iran has no antimicrobial properties. }, URL = {http://mlj.goums.ac.ir/article-1-1271-en.html}, eprint = {http://mlj.goums.ac.ir/article-1-1271-en.pdf}, journal = {Medical Laboratory Journal}, doi = {10.52547/mlj.15.2.18}, year = {2021} }
