Iyini i-pasteurization futhi ikugcina kanjani ukudla nesiphuzo kukusha izinyanga?

I-Pasteurization ilungele ubisi, uphuzo oludakayo, amajusi, nohlu lwezinto okudingeka uzigcine kodwa ungasebenzisi ngokweqile.

I-Pasteurization yinqubo encike ekwelashweni okushisa kokudla ukuze kubulawe amagciwane, amagciwane kanye nezinye izifo ekudleni.Le nqubo yasungulwa ngusokhemisi ongumFulentshi uLouis Pasteur, owazama ukujabulela iholide esifundeni sase-Arbois ngo-1864, kodwa wayithola. akunakwenzeka ukwenza kanjalo - ngoba amawayini endawo ayevame ukubamuncu kakhulu.Ngobungcweti bakhe besayensi nothando lwesiFulentshi lwewayini, uLouis uzothuthukisa indlela yokuvimbela ukonakaliswa kwamawayini asemancane ngalelo holidi.

Kodwa-ke, kubalulekile ukuqaphela ukuthi i-pasteurization ayikubulali amagciwane ekudleni (ibulala wonke amagciwane), kodwa ivele iwasuse ngenani elanele ukuze kungabi mathubeni okudala ukonakala komuntu noma izifo - kucatshangwa ukuthi umkhiqizo ugcinwa ngendlela eyalelwe ngayo futhi Uwusebenzise ngaphambi kwawo. usuku lokuphelelwa yisikhathi.Ukuvala inzalo kokudla akuvamile njengoba kuvame ukuthinta ukunambitheka kanye nekhwalithi yokudla, kodwa ngokungafani ne-pasteurization, inzalo isebenzisa ukushisa okuphezulu, ngakho ukudla nakho kuyacutshungulwa/kuphekwe, ngaleyo ndlela kushintshe ukubukeka nokunambitheka kokudla okucutshungulwe ngale ndlela, futhi i-pasteurization ingakhuphula ukugcina umbala nokunambitha kokudla.
