Abstract:

Effects of trehalose on thermal stability of nisin solution at pH 1.0 to 5.0 were studied. The results showed that pH value has a remarkable effect on the thermal stability of nisin which is the strongest at pH 3.0. Trehalose is beneficial to the thermal stability of nisin at pH 1.0 to 5.0. Therefore, trehalose can be used as a protective agent for nisin solution during autoclaving process.

Key words: nisin, stability, pH values, trehalose
