Nisin acts as a bioprotective agent to inhibit Listeria monocytogenes in hot dogs. By integrating Nisin into food protection systems, processed meat manufacturers can reduce spoilage losses, reduce product recalls, and reduce the use of chemical preservatives such as nitrite, nitrate and sorbic acid) needs.
The nisin has two kinds: nisin A and nisin Z (default).
Nisin A: Molecular Formula: C143H228N42O37S7 Molecular Weight: 3348
Nisin Z: Molecular Formula: C141H228N41O38S7 Molecular Weight: 3331
Nisin Z has the better solubility than nisin A.
