Yini uNisin
I-Nisin iyi-peptide yemvelo elwa namagciwane ekhiqizwa ukuvutshelwa kwe-nisin etholakala ngokwemvelo obisini nakushizi. Inomphumela we-antibacterial we-spectrum ebanzi futhi ingavimbela ngempumelelo ukukhula nokukhiqizwa kwamabhaktheriya amaningi egram-positive kanye nezinhlamvu zawo. Ikakhulukazi, inemiphumela evimbelayo ecacile ku-Staphylococcus aureus evamile, i-Streptococcus hemolyticus, i-botulinum namanye amagciwane, futhi ingadlala indima ekulondolozeni nasekulondolozeni ukudla okuningi. Ngaphezu kwalokho, i-nisin inokusimama okuhle, ukumelana nokushisa nokumelana ne-asidi, futhi inamathuba amahle okusebenza embonini yokudla.
Ukusetshenziswa kwe-Nisin
Inani le-nisin elisetshenzisiwe liyahlukahluka ngezinga lokushisa lokugcina kanye nempilo yeshalofu. I-Nisin iyisilondolozi semvelo semikhiqizo eminingi yokudla futhi iwuhlobo olusebenzayo, olungenabuthi, oluphephile, olungenayo imiphumela emibi yokudla, inokuncibilika okuhle nokuzinza, ngakho-ke isetshenziswa kabanzi esiphuzweni sokudla nobisi, futhi ingakwazi zisetshenziswe emikhiqizweni yezimonyo.
Okokuqala, i-Nisin ingafakwa ku-yogurt noma ubisi lwezithelo, inganweba impilo yeshalofu kusukela ezinsukwini eziyisithupha ekamelweni lokushisa kuya ngaphezu kwenyanga eyodwa.
Okwesibili, i-Nisin inohlu olubanzi lwezinhlelo zokusebenza, ezifanele zonke izinhlobo zemikhiqizo yamaShayina, entshonalanga, ephezulu, ephakathi kanye nesezingeni eliphansi. Isibonelo, izoso, i-ham, amasoseji, imikhiqizo yenkukhu kanye nemikhiqizo yesoso. Umphumela wayo we-antiseptic uyabonakala kakhulu, ongenza impilo yeshalofu yemikhiqizo yenyama ephansi yokushisa ifinyelele ngaphezu kwezinyanga ezintathu ekamelweni lokushisa.
I-Thrid, i-Nisin ingavimbela ngempumelelo ukukhula kwama-microorganisms, ithuthukise ikhwalithi yemikhiqizo futhi yandise isikhathi sokugcinwa kwemikhiqizo.
