Abstractepsilon-poly-L-lysine (e-PL) is a novel biopreservative with wide antibacterial spectrum, high safety, and stable property. However, the color of epsilon-PL generating from manufacturing process lowers its appearance and limits its application. This work aimed to decolorize epsilon-PL by hydrogen peroxide. Impacts of hydrogen peroxide concentration, pH, duration time and temperature were discussed. Physicochemical property and bioactivity of epsilon-PL were explored. Results indicated that 43.2 % color saturation and 94.54 % recovery rate were reached when the concentration of hydrogen peroxide, pH, duration time and temperature were 3.0 %, 7.0, 1.5 h and 70 degrees C respectively. Furthermore, the MIC (minimal inhibitory concentration) of the hydrogen peroxide treated epsilon-PL for Bacillus subtilis, Escherichia coli, and Staphylococcus aureus were 2 mg/mL, 0.1 mg/mL, and 0.1 mg/mL respectively, which was similar with untreated epsilon-PL. At last, cytotoxicity test indicated that no cytotoxicity could be observed at concentration lower than 2 mg/mL epsilon-PL. As a result, hydrogen peroxide treatment on epsilon-PL could significantly decolorize epsilon-PL without impairing the antibacterial performance and changing the cytotoxicity. Hydrogen peroxide treatment is a promising method to improve the appearance of products, to reduce the cost of decoloration, and to enlarge the application in food and cosmetics industry.
