Yintoni iNisin?

I-nisinyindawo yendalo yendalo efumene ingqalelo enkulu kumzi-mveliso wokutya ukuze akwazi ukuthintela ukukhula kweebhaktiriya ezithile, ngakumbi ezo zibangela ukuba ukutya oko kunye nokugula ukutya. Njengelungu losapho lakwa-lantibiotic, uNisin luveliswa ngokubiyela i-wacton ye-lactococcus lactis. Iipropathi zayo ezizodwa zenza ukuba igcinwe ikhuselekile, ngakumbi ukwandiswa kokutya kunye nolwandiso lobomi beShelsi. Kweli nqaku, siza kuphonononga iinkalo ezahlukeneyo zeNisin, kubandakanya imveliso, izicelo, kunye nendima yabathengisi kunye nabavelisi, ngakumbi eTshayina.

Imveliso ye-Nisin

Umgubo weNisin Iveliswa ngenkqubo yokuxhwila ebandakanya ukukhula * I-Lactococcus lactis * kwindawo elawulwayo. Intsholongwane ivelisa iNisin njengeendlela zokuzikhulela ngokuchasene ne-microorganisms ekhuphisanayo. Nje ukuba inkqubo yengozi igqityiwe, i-nisin ikhutshiwe kwaye ihlanjululwe ukuze isetyenziswe kwizicelo ezahlukeneyo.

I-China ivele njengomdlali ophambili kwimarike ye-Lactobacils yehlabathi, kunye nabavelisi abaninzi besenza inkqubela phambili yearhente ye-antimicrobial. Ezi fektri zibonelela ama-lactobacils kumashishini ahlukeneyo, kubandakanya ukwenziwa kokutya, amayeza, kunye ne-cosmetics. Intengiso eshushu yeLactobacilsus e-China ibonisa imfuno yokukhula kwezinto zendalo ezinokuphucula ukhuseleko lokutya ngaphandle kokulalanisa.

Ukusetyenziswa kweNisin

I-Nisin isetyenziswa njengokutya okutyayo kuba iyasebenza ngokuchasene noluhlu olubanzi lweebhaktiriya ezifanelekileyo, kubandakanya * i-listesia monocytogenes *, * i-staphylococcucus *. Ukukwazi kukaNisin ukunqanda ukuba ezi pathogens zenza ukuba zixabiseke ngakumbi ekuvelisweni kweemveliso zobisi, ukutya okuncinci, kunye nezemidlalo egqityiweyo.

I-1. Ubisi: UNisin uqhelenelwe kwimveliso yetshizi ukukhusela i-spoilage kwaye kwandiswe ubomi beshelsi. Inceda ukugcina umgangatho wetshizi ngokuthintela ukukhula kwe-spoilage kunye ne-pathogens.

2. Ukutya okuncinci: ukusebenzisa i-nisin ekutyeni okushiyekileyo kunceda ekuqinisekiseni ukuba imveliso ihlala ikhuselekile ukuba itye ixesha elide. I-Nisin isebenza ngokukhethekileyo kukutya okuphantsi kwe-acid apho umngcipheko we-botulism ukhona.

3. Inyama egqityiweyo: I-Lactobakiilli ihlala yongezwa kwinyama eqhubekileyo ukuthintela ukukhula kweentsholongwane eziyingozi, ngaloo ndlela kuphucule ukhuseleko lokutya kunye nokwandisa ubomi bemveliso.

I-4. Amayeza kunye ne-cosmetics Iipropathi zayo zokucoca zinceda ukukhusela ungcoliseko kwaye uqinisekise ukhuseleko lwemveliso.

Indima yomthengisi we-nisin powder

Abathengisi basePisin Powder badlala indima ebalulekileyo ekunikezelweni kwalearhente ye-avimicrocial. Baqinisekisa ukuba abavelisi banokufikelela kwi-lanctobacis ephezulu ye-lactobacil ehlangabezana neemfuno zolawulo. E China, zininzi abavelisi beLactobacilliss kwaye imakethi ikhuphisana kakhulu, ke iinkampani zinokufumana abathengisi abanikezela ngexabiso eliphezulu kunye nomgangatho.

Ukutya kwe-fipharm yinkampani edibeneyo yeI-Hainan Huayan I-collagenkunye neqela le-fipharm,i-collagenkwayeIzinto zokutyaziimveliso zethu eziphambili zentengiso.

Ikamva likaNisin kwishishini lokutya

Ibango le-Lactobakilli kulindeleke ukuba likhule njengokwazisa kwabathengi malunga nokubaluleka kokhuseleko lokutya kunye nokugcinwa kwendalo. Imeko yokuyila ilebhile ecocekileyo iimveliso igxininisa ekungafihlisiyo kunye nokusetyenziswa kwezithako zendalo, ezihambelana kakuhle neprofayili ye-Lactobacilli.

Ukongeza, uphando oluqhubekayo kwizicelo zeNisin luyaqhubeka nokubonisa ukusetyenziswa okutsha kuyo kwimizi-mveliso eyahlukeneyo. Umzekelo, izifundo zivavanya amandla okudibanisa i-nisin kunye nezinye izinto zendalo ukomeleza ukusebenza kwalo kwaye zandise imbonakalo yomsebenzi.

Kwisishwankathelo, iNisin yiarhente enamandla e-antimaial enoluhlu olubanzi lwezicelo kumashishini okutya nangaphaya. Ukuveliswa kweNisin, ngakumbi eTshayina, kwenza ukuba kufumaneke ngokulula abavelisi abafune izisombululo ezifanelekileyo zokulondolozwa kwendalo. Njengoko imarike ye-Nisin iyaqhubeka nokwandiswa, iinkampani kufuneka zikhethe abathengisi ngononophelo ukuqinisekisa ukuba bafumana imveliso esemgangathweni ehlangabezana neemfuno zabo. Ngokwenza umsebenzi wayo oqinisekisiweyo kunye nokuthandwa okukhulayo, uNisin kulindeleke ukuba adlale indima ebalulekileyo ekukhuseleni ukutya nokulondolozwa kwixesha elizayo.
