Uburyo bushya bwo gusukura amata y'ibitoki mu macupa bwahinduye amahame agenga umutekano w'ibiribwa

Uko icyifuzo cy’amata y’ibitoki yo mu macupa kigenda cyiyongera ku isi, uburyo bwo kurwanya indwara ziterwa no gufunga umubiri bwagaragaye nk'imbaraga zihindura umutekano w’ibiribwa no kunoza umusaruro. Ubu buryo bugezweho, bwagenewe cyane cyane amata y’ibitoki yo mu macupa, buhuza ubuhanga buhanitse n’imikorere yikora kugira ngo bugumane ubuziranenge bw’ibicuruzwa kandi bukomeze igihe cyo kubibika.

Igikorwa cyo gusubiza inyuma gishingiye ku buryo bukomeye bwo kwirinda bugizwe n'intambwe eshatu. Mbere na mbere, uduseke twuzuyemo amata y'ibitoki yo mu macupa dushyirwa mu cyumba cyo gusubiza inyuma, hanyuma hagafungwa urugi. Hanyuma uburyo bwo gufungana mu buryo butatu burakora, bugafata urugi mu buryo bwa mashini mu gihe cyose cyo guhagarika burundu kugira ngo hirindwe ko umwuka uva kandi urinde ababikora. Igikorwa cyose gicungwa mu buryo bwigenga na Porogaramu Igenzura ry'Ibintu (PLC), ikora uburyo bwo guhagarika burundu burundu hakoreshejwe uburyo bwa milisegonda.

Mu ntangiriro z'igikorwa cyo gusukura, umwuka ushyirwa mu miyoboro ikwirakwiza umwuka ahantu nyaburanga, wimura umwuka vuba binyuze mu miyoboro y'umwuka. Icyiciro cyo kuzamuka gitangira gusa iyo ibipimo by'ubushyuhe n'igihe byujuje ubushyuhe, bigatuma habaho ibidukikije bihamye by'ubushyuhe. Mu gihe cyo kuzamuka no gusukura umwuka, icyumba cyuzuye umwuka wuzuye, bigakuraho umwuka usigaye ushobora gutuma ubushyuhe bukwirakwira mu buryo butari bumwe. Ibikoresho bifunguye bituma umwuka ukomeza guhindagurika, bigakomeza ihinduka ry'ubushyuhe riri munsi ya ± 0.5°C mu dusanduku twose.

Iyi sisitemu yo gushyushya ifite ibintu byinshi bishya. Uburyo bwayo bwo gushyushya umwuka butuma ubushyuhe bwiyongera cyane—bugera kuri 121°C mu minota 5 kugeza ku 10—mu gihe bigabanya igihombo cy'ubushyuhe kikagera munsi ya 5%. Uburyo bwo kugarura ingufu bushobora gukoreshwa mu kongera umwuka no gushyushya ubushyuhe, bikagabanya ikiguzi cyo gukora kugeza kuri 30%. Uburyo bwo gukonjesha butaziguye, bukoreshwa n'icyuma gihindura ubushyuhe, burinda kwandura binyuze mu gutandukanya amazi n'umwuka n'icyuma gikonjesha, bigatuma hubahirizwa amahame y'isuku akomeye nka HACCP.

Uburyo bwo guhinduranya imiterere y’ibi bicuruzwa burenze amata y’ibitoki, butanga umusaruro mu buryo butandukanye bw’ibicuruzwa bikonjeshwa, kuva ku binyobwa bikomoka kuri poroteyine y’ibimera kugeza ku biryo by’amatungo, binyuze mu gupima neza imiterere y’ubushyuhe n’igihe hakurikijwe ingano zitandukanye z’ibicuruzwa n’ubwinshi bw’ibicuruzwa.

Gukoresha iri koranabuhanga mu nganda byatanze umusaruro ugaragara. Isosiyete ikomeye mu by’amata y’ibitoki yo muri Aziya y’Amajyepfo y’uburasirazuba yatangaje ko yagabanutseho 40% mu gusubiza ibicuruzwa nyuma yo guhuza uburyo bwo kubisubiza, ibi bikaba byaratewe n’ubushobozi bwayo bwo kurandura indwara zirwanya ubushyuhe nka Clostridium botulinum.

Kubera ko isoko mpuzamahanga ry’ibicuruzwa byo mu macupa rirenga miliyari 100 z’amadolari buri mwaka, igisubizo cyo gukingira indwara zo mu macupa kiri imbere mu guhanga udushya, gitanga ibicuruzwa bifite umutekano, ingaruka ku bidukikije zigabanuka, kandi kikongera icyizere cy’abaguzi. Kubera ko ubushakashatsi buri gukorwa bugamije gushyiramo ubwenge bw’ubukorano kugira ngo ibikorwa bigende neza mu buryo bwihuse, ahazaza h’umusaruro w’ibiribwa byo mu macupa bigaragara ko ari umutekano kandi birambye.
