Nisin (Innis), tseem hu ua lactobacillus peptide, yog ib yam khoom polypeptide uas tsim los ntawm Streptococcus lactis. Tom qab noj, nws sai sai hydrolyzed rau hauv amino acids nyob rau hauv lub cev pH ntawm tib neeg lub cev thiab kev ua ntawm α-chymotrypsin. Nws tsis hloov cov kab mob ib txwm muaj hauv tib neeg txoj hnyuv lossis ua rau muaj teeb meem tiv taus zoo li lwm yam tshuaj tua kab mob. Nisin yuav tsis muaj kev tiv taus hla nrog lwm yam tshuaj tua kab mob thiab yog ib qho tshuaj tiv thaiv zaub mov zoo heev, tsis muaj tshuaj lom, muaj kev nyab xeeb thiab zoo heev. Nws tuaj yeem tiv thaiv thiab tua cov hlwb cog thiab cov noob ntawm ntau yam kab mob Gram-positive xws li Bacillus stearophilus, Bacillus cereus, Staphylococcus aureus, Listeria thiab Clostridium botulinum. Thaum ntxiv rau hauv zaub mov, nws tuaj yeem txo qhov kub ntawm cov zaub mov, ua kom lub sijhawm tiv taus luv dua, thiab pab cov zaub mov khaws nws cov as-ham qub, saj thiab xim.
Nisin yog ib yam tshuaj tua kab mob uas tsuas tua tau thiab tiv thaiv tau cov kab mob Gram-positive xwb thiab tsis muaj txiaj ntsig zoo rau cov poov xab, cov kab mob Gram-negative thiab pwm. Hauv Suav teb, nws tau teev tseg tias nws tuaj yeem siv rau hauv cov khoom noj nqaij thiab cov khoom noj mis nyuj, nrog rau kev siv ntau tshaj plaws ntawm 0.5g / kg. Kev siv ntau tshaj plaws hauv cov dej haus protein cog thiab cov kaus poom yog 0.2g / kg.
