For example, Rose et al.
(1999) showed that glutathione, which is
present in raw ground beef, can inactivate
nisin. Scott and Taylor (1981) showed the
need for greater nisin concentration to inactivate
Clostridium botulinum in cooked
meat compared to microbiological medium.
Finally, Chung et al. (1989) showed a 70%
loss in nisin activity in raw meat during
storage at 5 ° C for 4 days.
