Nisinisilondolozi sokudla semvelo esithole ukuduma eminyakeni yamuva nje ngenxa yekhono laso lokwelula isikhathi seshelufu sokudla.I-Nisin, etholakala ku-Lactococcus lactis, iyisengezo sokudla esisetshenziswa kakhulu esingavimbela ngempumelelo ukukhula kwamagciwane, ikakhulukazi lawo abangela ukonakala kokudla.

Ibizwa ngokuthi i-polypeptide, i-nisin yenzeka ngokwemvelo ekudleni okuhlukahlukene okubilile futhi isetshenziswe ukulondoloza ukudla amakhulu eminyaka.Isebenza ngokukhomba izindonga zamangqamuzana amagciwane, okuwenza abhidlike futhi avimbele ukukhula kwawo.Le ndlela yemvelo yokusebenza ihlukanisa i-nisin kwezinye izigcina-makhemikhali zamakhemikhali, ezivame ukubeka izingozi zempilo ezingaba khona.

I-nisin yezinga lokudla ivunyelwe izinhlangano ezilawulayo ezifana neFood and Drug Administration (FDA) kanye ne-European Food Safety Authority (EFSA) njengesilondolozi sokudla okunhlobonhlobo.Lokhu kuhlanganisa inyama egayiwe, imikhiqizo yobisi, ukudla okusemathinini, ngisho neziphuzo.Ngenxa yemvelaphi yayo yemvelo kanye nephrofayili yokuphepha, i-nisin ithathwa kabanzi njengenketho ephephile nesebenzayo yokulondoloza.

Enye yezinzuzo eziyinhloko ze-nisin njengesilondolozi sokudla umsebenzi wayo we-antimicrobial obanzi.Kuye kwaboniswa ukuthi iyasebenza ngokumelene nezinhlobonhlobo eziningi zamagciwane, kufaka phakathi ezinye zezifo ezivame kakhulu ezitholakala ekudleni.Ngokuvimbela ukukhula kwala magciwane, i-nisin isiza ekuvimbeleni ukungcoliswa kokudla futhi yehlise nengozi yokugula okubangelwa ukudla.

Ngaphezu kwalokho, i-nisin ihlala izinzile ngisho nangaphansi kwezimo eziphakeme zokushisa nezimo ezine-acidic, okwenza ifanelekele izindlela ezihlukahlukene zokucubungula ukudla.Ukumelana nokushisa kwayo kuqinisekisa ukuthi igcina izici zayo zokulondolozwa kwemvelo ngisho nangemva kokupheka noma ukufakwa kwe-pasteurization, inwebe impilo yeshalofu ngaphandle kokufaka engcupheni ukunambitheka noma ikhwalithi.

Enye inzuzo ephawulekayo ye-nisin njengesilondolozi sokudla ukuthi inomthelela omncane ezinzwa zokudla.Ngokungafani nezinye izinto ezigcina amakhemikhali ezingashintsha ukunambitheka noma ukuthungwa kokudla, i-nisin itholakale ingenawo umthelela obalulekile ezimpahleni zezinzwa.Lokhu kusho ukuthi ukudla okulondolozwe nge-nisin kungagcina ukunambitheka kwakho kwangempela nokuthungwa, kunikeze abathengi umuzwa wekhwalithi ephezulu.

I-Nisin ivamise ukutholakala iwumpuphu futhi ingafakwa kalula ezinqubweni zokukhiqiza ukudla.Abakhiqizi bokudla bangangeza ukugxiliswa okuqondile kwempushana ye-nisin ekuhlanganiseni kwabo ukuze bathole umphumela wokulondoloza ofunekayo.Ukwengeza, i-nisin powder inokuzinza okuphezulu kanye nempilo ende yeshalofu, okwenza kube ukukhetha okungabizi kakhulu kokulondolozwa kokudla.

Sengiphetha, i-nisin iyisilondolozi sokudla esingokwemvelo esinezinzuzo eziningi.Izakhiwo zayo zokulwa namagciwane, umsebenzi obanzi, ukumelana nokushisa kanye nomthelela omncane ezimpahleni zezinzwa kuyenza ibe ithuluzi eliyigugu kubakhiqizi bokudla.Ngokuvunyelwa kwayo ngokomthetho kanye nokuphepha okuqinisekisiwe, i-nisin iyaqhubeka nokubamba iqhaza elibalulekile ekwandiseni isikhathi seshelufu semikhiqizo yokudla ehlukahlukene kuyilapho iqinisekisa ikhwalithi nokuphepha kubathengi.
