Solubility: Nisin, a light brown solid powder, needs to be dissolved in water or liquid for use, and its solubility varies depending on the pH level. In water (pH = 7), the solubility of Nisin is 49.0 mg/ml; in 0.02M hydrochloric acid, the solubility increases to 118.0 mg/ml; however, in alkaline conditions, it is almost insoluble.
Stability: The stability of Nisin is also influenced by the pH of the solution. For instance, when dissolved in skim milk with a pH of 6.5 and pasteurized at 85°C for 15 minutes, the activity loss is only 15%. When dissolved in dilute hydrochloric acid with a pH of 3, it retains 100% of its activity even after being autoclaved at 121°C for 15 minutes, demonstrating excellent acid and heat resistance.
Antibacterial Activity: Nisin effectively inhibits many Gram-positive bacteria that cause food spoilage, such as Lactobacillus, Streptococcus, Micrococcus, Staphylococcus, and Listeria. It is particularly effective against spore-forming bacteria like Bacillus and Clostridium species.
