Kungani Ubisi Kuludinga Ukuba Uguqulwe
Ukuphuza ubisi oluhlaza kungabangela ukugula okusongela ukudla okubangelwa ukuphila. Ungalimazi.
Ubisi obuthengayo esitolo sithengisiwe (kubandakanya ubisi oluphilayo ). I-pasteurization, ebizwa ngokuthi nguLouis Pasteur, iyindlela yokushisa ukudla okushisa okuphezulu okwanele ukubhubhisa amabhaktheriya ayingozi. I-pasteurization ayishintshi ukubaluleka komsoco wobisi ngakho-ke iqukethe inani elifanayo le-calcium nezinye izakhi.
Akuphephile ukuphuza ubisi oluhlaza, ngisho nasezikhungweni zobisi lapho abakhiqizi bethatha izinyathelo zokuphepha ezengeziwe. Ubisi obomvu bungaba yingozi empilweni yakho ngoba kungathatha amabhaktheriya angakwenza ugule. Eqinisweni, e-United States, akuvumelekile ukuthutha nokudayisa ubisi oluhlaza emigqeni yombuso, nakuba ezinye izindawo zivumela ubisi obuhlaza ukuthi buthengiswe endaweni yangakini. Udinga ukuhlola imithetho kuhulumeni wakho uma unesithakazelo ekuthengeni ubisi oluhlaza.
Ubisi obubi buyingozi kakhulu ezinganeni, izingane ezincane, abantu asebekhulile nalabo abanezinkinga zesistimu yomzimba. Izimpawu zokugula zifaka isicanucanu, ukuhlanza, isifo sohudo, ikhanda, izikhonda zesisu, umkhuhlane kanye nama-aches omzimba.
Izimangalo ezimanzi nezempilo Izimangalo
Abanye ababambe iqhaza lobisi abaluhlaza benza isimangalo sokuthi ama-pasteurization abulala ama-enzyme engokwemvelo ebisi (ayenayo) nokuthi lezo zinkimbinkimbi zinezindawo zokuphulukisa (akukho bufakazi besayensi obusekela lo mbono). Ayikho ubufakazi obunokwethenjelwa bokusekela isimangalo sokuthi ubisi oluhlaza lungcono kuwe ngenxa yanoma yini eyenziwa yi-enzyme emzimbeni wakho - ama-enzymes agonywa njenganoma iyiphi iphrotheni yokudla.
Esinye isimangalo ukuthi ubisi oluhlaza aluyi-allergenic encane. Kodwa ukuguqulwa kwamagciwane akusho umphumela kuma-proteine yobisi noma u-ushukela ushukela, ngakho-ke ukuphuza ubisi oluhlaza akukona ukunciphisa uketshezi lwebisi noma ukusiza ukungabi nesimo se-lactose. Abantu abangakwazi ukuphuza ubisi ngenxa yokwelashwa noma ukungabekezelelani kuyodingeka bagweme ubisi oluhlaza nobisi olungasetshenzisiwe.
Abesifazane abakhulelwe noma abancancisayo akufanele badle ubisi obuhlaza noma izinhlobo ezithile zeshizi elithambile. Abesifazane abakhulelwe bangadla ushizi okhulile kanzima, i-cottage shizi, kanye noshizi olucutshungulwayo. Ngokwesikhungo sase-US sokuLawula izifo:
"Gwema izinhlayiya ezithambile ezifana neFeta, Brie, Camembert, ushizi oluhlaza okwesibhakabhaka, kanye nesitayela saseMexico. (Izinkukhu ezinzima, ushizi ocutshungulwe, ushizi ukhilimu, i-cottage shizi, noma i-yogurt akudingeki kugwenywe.)"
Lezi zinhlobo ezithambile zashizi zingangcoliswa ne-listeria, engabangela ukutheleleka okukhulu kwabesifazane abakhulelwe, izinsana kanye nabantu abanamasosha omzimba ahlaselekile.
Izinkukhu ezinzima ezinzima ezifana ne-cheddar, provolone, ne-gouda aziyona inkinga futhi zingadliwa. Eqinisweni, lezi zitshalo ziwumthombo omuhle kakhulu we-calcium namaprotheni. Kodwa, nazo ziphakeme ngamakholori, ngakho-ke ukulawulwa kwesabelo kuyadingeka uma ubuka isisindo sakho.
