Mu myaka myinshi ishize, pasteurisation yakoreshejwe muguhindura no kubika ibiryo bitetse.Ariko, hamwe niterambere ryihuse ryubumenyi nubuhanga, ubushyuhe bukabije bwubushyuhe bwo hejuru bwamazi bwagiye busimbuza buhoro buhoro pasteurisation.Uburyo bwiza bwo guteka ibiryo bitetse, amavuta ashyushye arashobora kwemeza ubwiza bwibiryo bitetse, bifite akamaro kanini kuramba.Ibikurikira, umwanditsi wa Newkman aziga nawe:
igihe kirekire
Imyuka yubushyuhe bwo hejuru ikorwa na moteri yubushyuhe bwo hejuru yubushyuhe irashobora kugera hejuru ya 30 ° C, ishobora kwica bagiteri nyinshi.Indangantego ya koloni yibiribwa bitetse ihindurwamo amavuta ashyushye ni munsi cyane ugereranije na pasteurisation.Amashanyarazi ashyushye afite ubushyuhe bwinshi nimbaraga zikomeye zo kwinjira.Molekile ya parike irashobora kwinjira mumbere yibyo kurya bitetse kugirango ihindurwe, iteza imbere cyane kandi ikongerera igihe cyo kubaho nyuma yo gukonja.
Ibara ni ryiza cyane
Gukonjesha cyane birenze urugero ntibishobora gusa kuramba, ariko kandi bituma ibara ryibiryo rigaragara cyane.Mu minsi y'icyumweru, ibyokurya bisigaye abantu bose barya bibikwa muri firigo kugirango bikonje.Iyo zimaze gusohoka, ibara rizagaragara neza.Nyamara, nyuma yo guhindurwa na parike yubushyuhe bwo hejuru, ibara riracyari umutuku kandi ryaka, kandi uburyohe buraryoshye.
Impamvu zikomeye z'umutekano
Guhindura imirasire nimwe muburyo busanzwe bwo kuboneza urubyaro.Ikoresha ibyangiritse nimpinduka muburyo bwa molekile kugirango ibuze cyangwa yice mikorobe.Nuburyo bwangiza bwo kuboneza urubyaro kandi biroroshye kugumana ibisigazwa byimirasire.
Impamvu z'umutekano zo guhagarika amavuta ni ndende cyane, kandi amavuta akorwa no guhumeka amazi.Guhindura amavuta ntibizahindura imiterere ya molekuline yibiribwa, kandi ntibizatanga umwanda n ibisigazwa.Nuburyo bwiza cyane kandi bwiza bwo kuboneza urubyaro.
