I-nisinyindawo yokutya yendalo efumene ukuthandwa kwiminyaka yakutshanje ngenxa yokwandisa ubomi bokutya. I-Nisin, ethathwe kwiLactococcus lactis, sisiseko esisetyenziswa ngokuqhelekileyo esinokukuthintela ukukhula kweentsholongwane, ngakumbi ezo zibangela ukutya okonakalisiweyo.

Ihlelwe njenge-polypeptide, i-nisin yenzeka ngokwemvelo kwizinto zokutya kwaye isetyenziselwe ukugcina ukutya kangangeenkulungwane. Isebenza ngokujolisa kwiindonga zeseli zentsholongwane, ibangele ukuba baphule kwaye bakhusele ukukhula kwabo. Le ndlela yendalo yesenzo iyahlula-hlula i-niin evela kwezinye izinto zokuthambisa iikhemikhali, ezihlala zibeka emngciphekweni onokubakho.

I-Nisin ye-Nisin ivunyiwe ziiarhente zolawulo ezinjengokulawulwa kokutya kunye neziyobisi (i-FDA) kunye nogunyaziso lokukhuseleka kokutya eYurophu (i-EFSA) njengendawo yokugcina iintlobo ezahlukeneyo zokutya. Oku kubandakanya i-mets eqhotyoshelweyo, iimveliso zobisi, ukutya okuncinci, kunye neziselo. Ngenxa yemvelaphi yayo yendalo kunye neprofayile yokhuseleko, uNisin uthathwa ngokubanzi njengolukhetho olukhuselekileyo nolusebenzayo.

Esona sibonelelo siphambili seNisin njengendawo yokutya sisixhobo sokutya sisixhobo esibanzi se-chaimicrobial. Ibonisiwe ukuba iphumelele ngokuchasene neendidi ezahlukeneyo zebhakteriya, kubandakanya ezinye zezinto ezixhaphakileyo zokutya. Ngokuthintela ukukhula kwezi bacteria, iNisin inceda ukukhusela ungcoliseko lokutya kwaye inciphise umngcipheko wokugula okutya.

Ukongeza, uNisin uhlala uzinzo nkqu naphantsi kweqondo lobushushu ephezulu kunye neemeko ze-acidic, enza ilungele iindlela ezahlukeneyo zokutya. Ukuxhathisa ubushushu kuqinisekisa ukuba igcina iipropathi zayo zokugcina izinto zangaphambi kokupheka okanye ukutyhilwa, ukwandisa ubomi beshelufu ngaphandle kokuphambanisa incasa okanye umgangatho.

Elinye iNzumbileyo ibalulekileyo yeNisin njengendawo yokugcina ukutya kukuba inefuthe elincinci kwiipropathi zemvakalelo yokutya. Ngokungafaniyo neekhemikhali ezigcina izinto zokugcina ikhemikhali ezinokutshintsha incasa okanye ukuthungwa kokutya, i-Nisin yafunyanwa ukuba ayinampembelelo ebonakalayo kwiimpawu zemvakalelo. Oku kuthetha ukuba ukutya kugcinwe kunye noNisin kunokugcina incasa yabo yoqobo kunye nokubekwa, ukubonelela abathengi ngamava aphezulu.

I-Nisin ihlala ifumaneka ngefom yomgubo kwaye inokufakwa ngokulula kwiinkqubo zemveliso yokutya. Abavelisi bokutya banokongeza ukugxininiswa okuthethekileyo kwe-nisin Powder ukuya kwifomu yabo yokufezekisa isiphumo esifunekayo. Ukongeza, i-nisin powder inozinzo oluphezulu kunye nobomi obude baseShelsi, esenza ukhetho olusebenzayo lokulondolozwa kokutya.

Ukuqukumbela, iNisin ngokwenene kukutya kwendalo kugcinwe kwizibonelelo ezininzi. Ipropathi yayo yokuhlambela, umsebenzi obanzi, ukuxhathisa ubushushu kunye nefuthe elincinci kwipropathi yemvakalelo yenza isixhobo esibalulekileyo kubavelisi bokutya. Ngomsebenzi wayo olawulayo kunye nokhuseleko oluqinisekileyo, uNisin uqhubeka nokudlala indima ebalulekileyo ekuseni ubomi beemveliso zokutya ezahlukeneyo ngelixa kuqinisekisa umgangatho kunye nokhuseleko kubathengi.
