Nisin is stable at ambient temperatures. It is stable to heating under acid conditions, and will withstand 1210 for 30 min at pH 2.0 and 15 min at pH 3.0. But nisin is less stable at alkalescence condition.
So it can lower food sterilizing temperature, shorten sterilizing time, enhance food quality, reduce nutrition damage, and prolong food storage time.
