The Effect of Ethanol Propolis Extracts on Inhibition of Growth of Fusarium solani on Hen Eggs

Abstract

The inhibition of growth of Fusarium solani mold on the shells of coated table hen eggs of a ethanol extract of propolis was investigated. Hen eggs were inoculated with F. solani spores and then coated with propolis extract at a concentration of 1, 2, 3, 5 or 10% using the spray method. Hen eggs were stored at room temperature for 28 days. Weight loss and the color of coated hen eggs were checked during storage. The color of hen eggs was tested using the CIELab method. Propolis extract was found to inhibit the growth of F. solani on hen eggshells. A reduction of three log cycles in the number of molds was observed on hen eggs coated with 10% propolis extract. Coating hen eggs with propolis extract slowed down and limited weight loss. No statistically significant changes in color parameters or sensory characteristics were observed during storage of hen eggs. There was a slight smell of propolis on the shells of hen eggs. Spraying table hen eggs with propolis extract at a concentration of 10% can help to improve the microbiological safety of hen eggs in terms of anti-mold protection.
