Ibiryo biri mu macupa ni bishya cyane
Impamvu nyamukuru ituma abantu benshi bareka ibiryo byo mu macupa ni uko batekereza ko ibiryo byo mu macupa atari bishya.
Iri ivangura rishingiye ku bitekerezo by’abaguzi ku biryo byo mu macupa, bituma bagereranya igihe kirekire cyo kubirya no kutabirya neza. Ariko, ibiryo byo mu macupa ni ibiryo bishya bimara igihe kirekire kandi bimara igihe kirekire.
1. Ibikoresho fatizo bishya
Kugira ngo ibiryo byo mu macupa bibe bishya, inganda zikora ibiryo byo mu macupa zihitamo neza ibiryo bishya muri iki gihembwe. Hari n'ibigo bishyiraho aho bihinga n'aho birobera, kandi bigashyiraho inganda hafi aho kugira ngo zitegure umusaruro.
2. Ibiryo biri mu macupa bimara igihe kirekire
Impamvu ituma ibiryo byo mu macupa bimara igihe kirekire ni uko ibiryo byo mu macupa bifungwa mu buryo bw'umwuka kandi bigashyirwa mu buryo bushyushye cyane mu gihe cyo kubitunganya. Ahantu hakoreshwa umwuka mu buryo bushyushye cyane habuza ibiryo byangiritse mu buryo bushyushye cyane gukora kuri bagiteri ziri mu kirere, bigatuma ibiryo bidahumanywa na bagiteri aho byaturutse.
3. Nta mpamvu yo gukoresha imiti irinda ubushyuhe kuri byose
Mu 1810, ubwo ibiryo byo mu macupa byavukaga, ibintu bigezweho byo kubika ibiryo nka aside sorbic na aside benzoic byari bitaravumburwa na gato. Kugira ngo bongere igihe cyo kumara ibiryo, abantu bakoresheje ikoranabuhanga ryo kubika ibiryo mu macupa kugira ngo bakore ibiryo mu macupa.
Ku bijyanye n'ibiryo byo mu macupa, abantu benshi babanza "kwanga". Abantu bahora batekereza ko ibiryo bishobora kongera igihe cyo kubikwa, kandi ibiryo byo mu macupa akenshi bimara igihe kirekire, bityo abantu benshi bibeshya ko ibiryo byo mu macupa bigomba kuba byongeyeho ibiryo byinshi byo mu macupa. Ese ibiryo byo mu macupa byongerwaho ibiryo byinshi byo mu macupa, nk'uko rubanda rubivuga?
Kuzigama? Oya rwose! Mu 1810, ubwo amacupa yavukaga, kubera ko ikoranabuhanga ryo gukora ritari rijyanye n'ibipimo, ntibyashobokaga gushyiraho ahantu hadakoreshejwe umwuka. Kugira ngo bongere igihe cyo kumara ibiryo, abakora icyo gihe bashobora kongeramo ibintu bizigama. Ubu muri 2020, urwego rw'iterambere rya siyansi n'ikoranabuhanga rwari ruri hejuru cyane. Abantu bashobora gushyiraho ahantu hadakoreshejwe umwuka kugira ngo barebe neza isuku y'ibiryo, kugira ngo udukoko dusigaye tutabasha gukura tudafite umwuka wa ogisijeni, kugira ngo ibiryo biri mu macupa bishobore kubikwa igihe kirekire.
Bityo rero, bitewe n'ikoranabuhanga ririho ubu, nta mpamvu yo kongeramo ibintu bibungabunga ibidukikije. Ku biryo byo mu macupa, abantu benshi baracyafite ibintu byinshi batabyumva neza. Dore bimwe mu bisubizo:
1. Ibiryo biri mu macupa ntabwo ari bishya?
Impamvu nyamukuru ituma abantu benshi badakunda ibiryo byo mu macupa ni uko batekereza ko ibiryo byo mu macupa atari bishya. Abantu benshi mu buryo butari bwo bagereranya "igihe kirekire" n'"ibitari bishya", mu by'ukuri si byo. Akenshi, ibiryo byo mu macupa biba bishya kurusha imbuto n'imboga uguze muri supermarket.
Inganda nyinshi zo mu macupa zizashyiraho ahantu ho gutera inyanya hafi y’inganda. Reka dufate urugero rw’inyanya zo mu macupa: mu by’ukuri, bifata igihe kitarenze umunsi umwe gutoragura, gukora no gufunga inyanya. Ni gute zishobora kuba nshya kurusha imbuto n’imboga nyinshi mu gihe gito! N’ubundi kandi, mbere y’uko abaguzi bazigura, imbuto n’imboga byitwa ko ari nshya zari zaramaze guhura n’ingorane ya 9981 kandi zatakaje intungamubiri nyinshi. Mu by’ukuri, ibiryo byinshi byo mu macupa bifite intungamubiri nyinshi kuruta ibiryo bishya urya.
2.Imara igihe kirekire cyane, ni iki kirimo kuba?
Twamaze kuvuga imwe mu mpamvu zituma amacupa amara igihe kirekire, ni ukuvuga ahantu hadakoreshejwe umwuka, naho iya kabiri ni ugusukura ubushyuhe bwinshi. Gusukura ubushyuhe bwinshi, bizwi kandi nka pasteurization, bituma ibiryo byasizwe ubushyuhe bwinshi bitazongera gukorana na bagiteri mu kirere, ibyo bikaba byitwa gukumira ko ibiryo byanduzwa na bagiteri ziva aho byaturutse.
3. Ibiryo byo mu macupa ntabwo bifite intungamubiri nk'ibiryo bishya!
Kubura intungamubiri ni impamvu ya kabiri ituma abaguzi banga kugura ibiryo byo mu macupa. Ese ibyo biribwa byo mu macupa bifite intungamubiri koko? Mu by'ukuri, ubushyuhe bwo gutunganya inyama zo mu macupa ni hafi 120 ℃, ubushyuhe bwo gutunganya imboga n'imbuto zo mu macupa ntiburenze 100 ℃, mu gihe ubushyuhe bwo guteka kwacu kwa buri munsi burenze 300 ℃. Kubwibyo, gutakaza vitamine mu gihe cyo kuziteka bizarenga igihombo cyo kuziteka, kuziteka, kuziteka no kuziteka? Byongeye kandi, ibimenyetso byemewe cyane byo gupima ubushya bw'ibiryo ni ukureba urwego rw'intungamubiri z'umwimerere mu biribwa.
