Food preservatives come in many different forms and types; few have shown as much potential as nisin
Nisin, which is currently one of the most well-known peptides in food preservation, has been in popular use for nearly a century. Shown to be a wide spectrum solution to the common bacteria of cheese, meat and a variety of other applications, nisin is a highly effective solution for the prevention of fungi, yeast and bacteria related food spoilage, including lactic acid bacteria. Especially effective against Gram-positive bacteria, it can be used in combination with other food preservation techniques, such as heat shock, to target Gram-negative bacteria as well. The main purpose of nisin is to prolong shelf life and increase overall food safety.
