Ukurikije ubwoko bwa byeri, urashobora kubinywa mu icupa kuruta kanseri. Ubushakashatsi bushya bwerekanye ko amber ale iba nziza iyo unyweye mu icupa mu gihe uburyohe bw’Ubuhinde Pale Ale (IPA) budahinduka iyo bumaze gukoreshwa mu kabati.

Kurenga amazi na Ethanol, byeri ifite ibihumbi byinshi by uburyohe byakozwe na metabolite ikozwe numusemburo, hops, nibindi bikoresho. Uburyohe bwa byeri butangira guhinduka bikimara gupakirwa no kubikwa. Imiti yimiti isenya uburyohe kandi igakora izindi, bigira uruhare mubusaza cyangwa inzoga zishaje abantu babona iyo bafunguye ikinyobwa.
Inzoga zimaze igihe kinini zikora uburyo bwo kongera ubuzima bwigihe no kwirinda byeri zishaje. Nyamara, ubushakashatsi bwinshi bwerekeranye no gusaza byeri byibanze ahanini kumurabyo hamwe nitsinda rito ryimiti. Muri ubu bushakashatsi buriho, abashakashatsi bo muri kaminuza ya leta ya Colorado barebye ubundi bwoko bwa byeri nka amber ale na IPA. Bagerageje kandi kureba imiti ihamye yinzoga zipakiye mumacupa yikirahure na bombo ya aluminium.

Can hamwe nuducupa twa amber ale na IPA byakonje ukwezi hanyuma bigasigara mubushyuhe bwicyumba andi mezi atanu kugirango bigane ububiko busanzwe. Buri byumweru bibiri, abashakashatsi barebaga metabolite mu bikoresho bishya byafunguwe. Uko igihe cyagendaga gihita, kwibumbira hamwe kwa metabolite - harimo aside amine na esters - muri amber ale byari bitandukanye cyane bitewe n’uko byapakiwe mu icupa cyangwa se.

Imiti ihindagurika ya IPAs ntiyahindutse mugihe yabitswe mu isafuriya cyangwa icupa, ubushakashatsi abanditsi bavuga ko ari ukubera ko polifenole yibanda cyane kuri hops. Polifenole ifasha kwirinda okiside no guhuza aside amine, ibemerera kuguma muri byeri kuruta kuyifata imbere mu kintu.

Umwirondoro wa metabolike ya amber ale na IPA wahindutse mugihe, utitaye ko washyizwe mumasanduku cyangwa icupa. Nyamara, amber ale mumabati yari afite itandukaniro rinini muburyo bwa flavour igihe kirekire yabitswe. Nk’uko abanditsi b’ubushakashatsi babitangaje, abahanga mu bya siyansi nibamara kumenya uburyo metabolite n’ibindi bivanga bigira ingaruka ku buryohe bwa byeri, birashobora gufasha mu gufata ibyemezo byinshi byerekeranye nubwoko bwiza bwo gupakira kubwoko bwabo bwa byeri.
