Methylcellulose ni inyongeramusaruro isanzwe mu biribwa. Ikozwe muri cellulose karemano binyuze mu guhindura imiti. Ifite ubushobozi bwo kudahinduka, gusya no gukurura kandi ikoreshwa cyane mu nganda z'ibiribwa. Nk'ikintu cyahinduwe mu buryo bw'ubukorano, umutekano wayo mu biribwa umaze igihe kinini uhangayikishije.
1. Imiterere n'imikorere ya methylcellulose
Imiterere ya molekile ya methylcellulose ishingiye kuβIgice cya -1,4-glucose, gishingwa no gusimbuza amatsinda amwe ya hydroxyl n'amatsinda ya methoxy. Irashongeshwa mu mazi akonje kandi ishobora gukora gel ishobora gusubiramo mu bihe bimwe na bimwe. Ifite ubushobozi bwo gukomera, gukurura, guhagarika, kugumana amazi neza no kubika neza. Iyi mirimo ituma ikoreshwa cyane mu mugati, mu mafunguro ya keke, mu binyobwa, mu bikomoka ku mata, mu biribwa bikonje n'ahandi. Urugero, ishobora kunoza imiterere y'ifu no gutinda gusaza; mu biribwa bikonje, ishobora kunoza ubudahangarwa bw'ifu no kuyifunga.
Nubwo ifite imikorere itandukanye, methylcellulose ubwayo ntabwo yinjizwa cyangwa ngo ikoreshwe mu mubiri w'umuntu. Iyo imaze kunyobwa, isohoka cyane cyane mu nzira y'igogora mu buryo butari busanzwe, bigatuma ingaruka zayo ku mubiri w'umuntu zisa n'aho ari nke. Ariko, iyi miterere yanateye impungenge abantu ko kuyinywa igihe kirekire bishobora kugira ingaruka ku buzima bw'amara.
2. Isuzumabumenyi ry'uburozi n'inyigo z'umutekano
Ubushakashatsi bwinshi bwakozwe ku burozi bwagaragaje ko methylcellulose ifite ubushobozi bwo guhuza neza n'uburozi buke. Ibisubizo by'ibizamini by'uburozi by'akaga byagaragaje ko LD50 yayo (igipimo cy'uburozi bw'ikigereranyo) yari hejuru cyane ugereranyije n'ingano ikoreshwa mu biryo bisanzwe, bigaragaza umutekano uri hejuru. Mu ibizamini by'uburozi by'igihe kirekire, imbeba, imbeba n'izindi nyamaswa ntizagaragaje ingaruka mbi zikomeye mu gihe cyo kugaburira imbeba igihe kirekire ku gipimo kinini, harimo n'ingaruka nko kurwara kanseri, gutera teratogenicity no kubyara.
Byongeye kandi, ingaruka za methylcellulose ku mara y'umuntu nazo zarakoreweho ubushakashatsi bwinshi. Kubera ko idashyirwa mu gifu cyangwa ngo inyurwe, methylcellulose ishobora kongera ubwinshi bw'umwanda, igatuma amara ahora mu mubiri, kandi ikagira akamaro mu kugabanya impatwe. Muri icyo gihe, ntabwo iterwa n'ibimera byo mu mara, bikagabanya ibyago byo kubyimba cyangwa kubabara mu nda.
3. Amabwiriza n'amahame ngenderwaho
Imikoreshereze ya methylcellulose nk'inyongeramusaruro ku biryo igenzurwa cyane ku isi yose. Dukurikije isuzuma ryakozwe na Komite Ihuriweho y'Impuguke ku Nyongeramusaruro ku Biribwa (JECFA) hakurikijwe Ishami ry'Umuryango w'Abibumbye ryita ku Biribwa n'Ubuhinzi (FAO) n'Ishami ry'Umuryango w'Abibumbye ryita ku Buzima (OMS), ifunguro rya buri munsi ryemewe rya methylcellulose "ntiryavuzwe neza", bigaragaza ko ari byiza kuyikoresha mu rugero rwagenwe.
Muri Leta Zunze Ubumwe za Amerika, methylcellulose ishyirwa ku rutonde rw'ibintu byemewe muri rusange nk'ibikomoka ku biryo n'imiti (GRAS) n'ikigo gishinzwe ibiribwa n'imiti muri Amerika (FDA). Mu Muryango w'Ubumwe bw'u Burayi, ishyirwa mu cyiciro cy'inyongeramusaruro z'ibiribwa E461, kandi ikoreshwa ryayo ntarengwa mu biribwa bitandukanye ryagaragajwe neza. Mu Bushinwa, ikoreshwa rya methylcellulose rigenzurwa kandi n'"Ihame ry'Igihugu ry'Umutekano w'Ibiribwa" (GB 2760), risaba kugenzura neza ingano y'ibiryo hakurikijwe ubwoko bw'ibiribwa.
4. Ibitekerezo ku mutekano mu bikorwa bifatika
Nubwo umutekano wa methylcellulose muri rusange uri hejuru, ikoreshwa ryayo mu biribwa riracyagomba kwitabwaho ku ngingo zikurikira:
Igipimo: Kongeramo ibiryo cyane bishobora guhindura imiterere y'ibiryo no kugira ingaruka ku buryo bwo kumva; muri icyo gihe, kurya ibintu byinshi bifite fibre bishobora gutera kubyimba cyangwa kubabara mu igogora.
Abaturage bireba: Ku bantu bafite imikorere mibi y'amara (nk'abageze mu za bukuru cyangwa abana bato), methylcellulose nyinshi ishobora gutera ubumuga mu gihe gito, bityo igomba gutoranywa witonze.
Imikoranire n'ibindi bikoresho: Muri bimwe mu biryo, methylcellulose ishobora kugira ingaruka nziza hamwe n'ibindi bikoresho cyangwa ibindi bikoresho, kandi ingaruka zabyo zigomba kwitabwaho.
5. Incamake n'Icyerekezo
Muri rusange,metiliselulose ni inyongeramusaruro nziza kandi yizewe itazangiza ubuzima bw'abantu mu gihe gikwiye. Imiterere yayo idapfa gukururwa ituma ihora ihindagurika mu nzira y'igogora kandi ishobora kuzana inyungu zimwe na zimwe ku buzima. Ariko, kugira ngo irusheho kuba umutekano mu gihe kirekire, ni ngombwa gukomeza kwita ku bushakashatsi bw'uburozi n'amakuru afatika ku ikoreshwa ryayo, cyane cyane ingaruka zayo ku bantu bihariye.
Bitewe n’iterambere ry’inganda z’ibiribwa no kunoza icyifuzo cy’abaguzi ku bwiza bw’ibiribwa, uburyo bwo gukoresha methylcellulose bushobora kwaguka. Mu gihe kizaza, hakwiye gusuzumwa uburyo bushya bwo kugenzura umutekano w’ibiribwa kugira ngo haboneke agaciro kanini ku nganda z’ibiribwa.
