Kwiminyaka emininzi edlulileyo, i-pasteurization yayisetyenziselwa ukuvala inzala kunye nokugcinwa kokutya okuphekiweyo.Nangona kunjalo, ngophuhliso olukhawulezayo lwesayensi kunye netekhnoloji, ubushushu obuphezulu bobushushu obuphezulu bokuvala inzala ngokuthe ngcembe buthabathel' indawo i-pasteurization yesintu.Indlela efanelekileyo yokupheka ukutya okuphekiweyo, i-steam eshushu kakhulu inokuqinisekisa umgangatho wokutya okuphekiweyo, okubaluleke kakhulu ukwandisa ubomi beshelufu.Okulandelayo, umhleli weNewkman uya kufunda nawe:
ubomi beshelufu obandisiweyo
Umphunga wobushushu obuphezulu oveliswa yijenereyitha yomphunga enobushushu obuphezulu unokufikelela ngaphezulu kwe-30°C, enokubulala iibhaktheriya ezininzi.Isalathiso sekholoni yokutya okuphekiweyo okwenziwa inzala ngomphunga oshushu kakhulu singaphantsi kakhulu kuneso se-pasteurization.Umphunga oshushu kakhulu unobushushu obuphezulu kunye namandla anamandla okungena.Iimolekyuli zomphunga zinokungena ngaphakathi kokutya okuphekiweyo ukuvala inzala, nto leyo ekhuthaza ukuvala inzala ngokupheleleyo kwaye yandise ubomi beshelufu emva komkhenkce.
Umbala ubalasele ngakumbi
I-Superheated sterilization yomphunga ayikwazi nje ukwandisa ubomi beshelufu, kodwa yenza umbala wokutya uvelele ngakumbi.Ngeentsuku zeveki, izitya eziseleyo ezityiwa ngumntu wonke zigcinwa efrijini ukuze zifakwe efrijini.Xa zikhutshiwe, umbala uya kubonakala umnyama kwaye unqabile.Nangona kunjalo, emva kokuvalwa inzala ngumphunga obushushu obuphezulu, umbala usebomvu kwaye uqaqambile, kwaye incasa imnandi.
Ukhuseleko oluphezulu
Ukuvala inzala ngemitha ikwayenye yeendlela eziqhelekileyo zokuvala inzala.Isebenzisa umonakalo kunye notshintsho kwisakhiwo se-molecular inhibit okanye ukubulala i-microorganisms.Yindlela eyonakalisayo yokuvala inzala kwaye kulula ukugcina iintsalela zemitha.
Ukhuseleko lokuvala inzala ngomphunga luphezulu kakhulu, kwaye umphunga wenziwa ngamanzi aphuma abe ngumphunga.Ukwenziwa inzala komphunga akusayi kutshintsha imolekyuli yokutya, kwaye akuyi kuvelisa ungcoliseko kunye neentsalela.Yindlela ekhuseleke kakhulu kwaye esempilweni yokuvala inzala.
