Yintoni uNisin
I-Nisin yi-peptide yendalo yebhayoloji ye-antibacterial eveliswa kukubiliswa kwe-nisin ekhoyo ngokwemvelo kubisi kunye netshizi.Ine-antibacterial effect ebanzi kwaye inokuthintela ngokufanelekileyo ukukhula kunye nokuveliswa kweebhaktheriya ezininzi zegram-positive kunye ne-spores yazo.Ngokukodwa, ineempembelelo ezicacileyo zokuthintela kwi-Staphylococcus aureus eqhelekileyo, iStreptococcus hemolyticus, i-botulinum kunye nezinye iibhaktheriya, kwaye inokudlala indima ekugcinweni nasekugcineni ukutya okuninzi.Ukongeza, i-nisin inozinzo oluhle, ukumelana nobushushu kunye nokumelana ne-asidi, kwaye inethuba elihle lokusebenzisa kwishishini lokutya.
Ukusetyenziswa kweNisin
Isixa se-nisin esisetyenzisiweyo siyahluka ngobushushu bokugcina kunye nobomi beshelufu.I-Nisin sisilondolozi sendalo kwiimveliso ezininzi zokutya kwaye luhlobo olusebenzayo, olungeyotyhefu, olukhuselekileyo, alunamiphumo imiphumo yokutya, lunokunyibilika okulungileyo kunye nozinzo, ngoko ke lusetyenziswa kakhulu ekutyeni nakwisiselo sobisi, kananjalo luyakwazi zisetyenziswe kwiimveliso zokuthambisa.
Okokuqala, i-Nisin inokongezwa kwi-yogurt okanye ubisi lweziqhamo, inokwandisa ubomi beshelufu ukusuka kwiintsuku ezintandathu kwiqondo lobushushu begumbi ukuya kwinyanga enye.
Okwesibini, i-Nisin inoluhlu olubanzi lwezicelo, ezifanelekileyo kuzo zonke iintlobo zeemveliso zaseTshayina, zasentshona, eziphezulu, eziphakathi kunye neziphantsi.Ngokomzekelo, i-barbecue, i-ham, i-sausage, iimveliso zenkukhu kunye neemveliso zesosi.Umphumo wayo we-antiseptic uyabonakala kakhulu, onokuthi wenze ishelufu yemveliso yenyama ephantsi yobushushu ifikelele ngaphezu kweenyanga ezintathu kwiqondo lokushisa.
I-Thrid, i-Nisin inokuthintela ngokufanelekileyo ukukhula kwee-microorganisms, ukuphucula umgangatho weemveliso kunye nokwandisa ixesha lokugcinwa kweemveliso.
