Emgqeni wokukhiqiza wokucubungula ukudla, ukuvala inzalo kwezinga lokushisa eliphezulu kubaluleke kakhulu.Inhloso eyinhloko yokuvala inzalo i-Bacillus botulinum, engakhiqiza ubuthi obudala umonakalo obulalayo emzimbeni womuntu.Kuyibhaktheriya ye-anaerobic ukumelana nokushisa engakwazi ukuchayeka ezingeni lokushisa elingu-121°C.Izolahlekelwa umsebenzi wayo webhayoloji phakathi nemizuzu emithathu, futhi izolahlekelwa umsebenzi wayo webhayoloji endaweni engu-100°C cishe amahora ayi-6.Yiqiniso, lapho izinga lokushisa liphakeme, isikhathi sokusinda samagciwane siba sifushane.Ngokokuhlola kwesayensi, ukuvala inzalo kufaneleka kakhulu ku-121℃.Ngalesi sikhathi, ukupakishwa kunokumelana okuhle nokushisa futhi ukunambitheka kokudla kuhle kakhulu.Uma kufakwa inzalo ku-121°C, inani lika-F lesikhungo sokudla lifinyelela ku-4, futhi i-botulinum ye-B. ngeke ibonakale ekudleni, ehlangabezana nezidingo zokungabi nanzalo kwezohwebo.Ngakho-ke, lapho sibulala amagciwane emikhiqizo yenyama, izinga lokushisa ngokuvamile lilawulwa cishe ku-121°C.Izinga lokushisa eliphakeme kakhulu lizophazamisa ukunambitheka kokudla!
Indlela yokuvala inzalo
1. Ukuvala inzalo emanzini ashisayo:
Ngesikhathi sokuvala inzalo, konke ukudla ebhodweni kucwiliswe emanzini ashisayo, futhi ukusatshalaliswa kokushisa kungaphezulu ngale ndlela.
2. Ukuvalwa inzalo ku-steam:
Ngemuva kokuthi ukudla kufakwe ebhodweni, amanzi awafakwa kuqala, kodwa ngqo ku-steam ukuze ashise.Ngenxa yokuthi kunezindawo ezibandayo emoyeni ebhodweni ngesikhathi senqubo yokuvala inzalo, ukusabalalisa ukushisa ngale ndlela akuyona into efanayo kakhulu.
3. Ukuvalwa kwesifutho samanzi:
Le ndlela isebenzisa imibhobho noma amapayipi ukufafaza amanzi ashisayo ekudleni.Inqubo yokuvala inzalo ukufafaza amanzi ashisayo amise okwenkungu ebusweni bokudla ngokusebenzisa imibhobho efakwe nhlangothi zombili noma ngaphezulu ebhodweni lokuvala inzalo.Akukhona nje kuphela izinga lokushisa elifana neyunifomu futhi alikho ikona elifile, kodwa futhi isivinini sokushisisa nokupholisa siyashesha, esingase sihlanganise imikhiqizo ebhodweni ngokugcwele, ngokushesha nangokuzinza, elungele ukuvala inzalo kokudla okupakishwe ngokuthambile.
4. Ukuvala inzalo yokuxuba umhwamuko wamanzi:
Le ndlela yokuvala inzalo yethulwa yiFrance.Ihlanganisa ngobuhlakani uhlobo lwe-steam kanye nohlobo lweshawa yamanzi.Inani elincane lamanzi lifakwa ebhodweni ukuhlangabezana nokusetshenziswa kwesifutho esijikelezayo.I-steam ingena ezweni ngokuqondile, eliqaphela ngempela ukusebenza kahle okuphezulu kwesikhathi esifushane, ukonga amandla nokuvikelwa kwemvelo, futhi ifanele imikhiqizo ekhethekile.Ukuvala inzalo.
Izinyathelo zokuzivikela
Ukuvalwa kwezinga lokushisa okuphezulu kubaluleke kakhulu embonini yokucubungula ukudla.Inezici ezimbili ezilandelayo:
1. Isikhathi esisodwa: Umsebenzi wokukhipha inzalo ekushiseni okuphezulu kufanele uqedwe ngesikhathi esisodwa kusukela ekuqaleni kuze kube sekupheleni, ngaphandle kokuphazamiseka, futhi ukudla akukwazi ukuvalwa inzalo ngokuphindaphindiwe.
2. Ukukhishwa komphumela wokuvala inzalo: ukudla okuvalwa inzalo akukwazi ukubonwa ngeso lenyama, futhi ukuhlolwa kwesiko lebhaktheriya nakho kuthatha isonto lonke, ngakho-ke akunakwenzeka ukuhlola umphumela wokuvala inzalo weqoqo ngalinye lokudla elifakwe inzalo.
Ngokusekelwe ezicini ezingenhla, lokhu kudinga ukuthi abakhiqizi:
1. Okokuqala, kufanele senze kahle ngokufana kwenhlanzeko kwalo lonke uchungechunge lokucubungula ukudla, futhi siqinisekise ukuthi inani lokuqala lamagciwane esikhwameni ngasinye sokudla ngaphambi kokupakisha liyalingana, ukuze kuqinisekiswe ukusebenza kahle kwefomula yokuvala inzalo emisiwe.
2. Imfuneko yesibili iwukuba nesisetshenziswa sokuvala inzalo esisebenza kahle nokulawula izinga lokushisa okunembile, nokusebenzisa ifomula yokuvala inzalo emisiwe ngaphandle kokwehluleka kanye nephutha elincane ukuze kuqinisekiswe izinga nokufana komphumela wokuvala inzalo.
