Eminyakeni eminingi edlule, i-pasteurization yayisetshenziselwa ukuvala inzalo nokugcina ukudla okuphekiwe. Kodwa-ke, ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ukuvala inzalo kwesitimu esishisa kakhulu esishisa kakhulu sekuthathele indawo yokwelapha okujwayelekile. Indlela enhle yokupheka inzalo yokudla okuphekiwe, umusi oshisa kakhulu ungaqinisekisa ikhwalithi yokudla okuphekiwe, okubaluleke kakhulu ukwandisa isikhathi sokuphila kweshalofu. Okulandelayo, umhleli we-Newkman uzofunda nawe:
impilo yeshelufu enwetshiwe
Isitimu esinezinga lokushisa eliphezulu esikhiqizwa ijeneretha yesitimu esishisa kakhulu singafinyelela ngaphezu kuka-30°C, esingabulala amagciwane amaningi. Inkomba yekholoni yokudla okuphekwe inzalo ngesitimu esishisa kakhulu iphansi kakhulu kunaleyo ye-pasteurization. Umusi oshisa kakhulu unokushisa okuphezulu namandla okungena aqinile. Ama-molecule e-steam angangena ngaphakathi kokudla okuphekiwe ukuze abulale inzalo, okukhuthaza ukuvala inzalo okuphelele futhi andise impilo yeshalofu ngemva kokubanda.
Umbala ugqame kakhulu
I-Superheated sterilization ye-steam ayikwazi nje ukwandisa impilo yeshalofu, kodwa futhi yenza umbala wokudla uvelele kakhulu. Phakathi nezinsuku, izitsha ezisele ezidliwa yiwo wonke umuntu zigcinwa esiqandisini ukuze zifakwe esiqandisini. Uma zikhishwa, umbala uzovela ufiphele futhi ufiphele. Nokho, ngemva kokuvalwa inzalo ngesitimu esishisa kakhulu, umbala usebomvu futhi ugqamile, futhi ukunambitheka kumnandi.
Isici sokuphepha esiphezulu
Ukuvala inzalo ngemisebe nakho kungenye yezindlela ezijwayelekile zokuvala inzalo. Isebenzisa umonakalo kanye nezinguquko kusakhiwo samangqamuzana ukuvimbela noma ukubulala ama-microorganisms. Kuyindlela ebhubhisayo yokuvala inzalo futhi kulula ukugcina izinsalela zemisebe.
Isici sokuphepha sokuvala inzalo ngesitimu siphezulu kakhulu, futhi isitimu sakhiwa ngamanzi ahwamukayo. Ukuvala inzalo ngesitimu ngeke kushintshe ukwakheka kwamangqamuzana okudla, futhi ngeke kukhiqize ukungcola nezinsalela. Kuyindlela ephephile futhi enempilo yokuvala inzalo.
