Umutekano wa methylcellulose mubiryo

1. Ibyiza n'imikorere ya methylcellulose

Imiterere ya molekile ya methylcellulose ishingiye kuriβIgice cya -1,4-glucose, ikorwa mugusimbuza amatsinda amwe ya hydroxyl hamwe nitsinda ryimikorere. Irashobora gushonga mumazi akonje kandi irashobora gukora gel ihindagurika mubihe bimwe. Ifite umubyimba mwiza, emulisifike, guhagarikwa, gutuza no gufata amazi. Iyi mikorere ituma ikoreshwa cyane mumigati, imigati, ibinyobwa, ibikomoka ku mata, ibiryo bikonje ndetse nindi mirima. Kurugero, irashobora kunoza imiterere yimigati no gutinda gusaza; mu biryo byafunzwe, birashobora kunoza ubukonje bukonje.

Nubwo imikorere yayo itandukanye, methylcellulose ubwayo ntabwo yinjizwa cyangwa ngo ihindurwe mumubiri wumuntu. Nyuma yo gufatwa, isohoka cyane cyane binyuze mu nzira igogora muburyo butabangamiwe, bigatuma ingaruka zayo zitaziguye kumubiri wumuntu zigaragara nkaho ari nke. Nyamara, ibi biranga kandi byakuruye abantu impungenge ko gufata igihe kirekire bishobora kugira ingaruka kubuzima bwo munda.

2. Isuzuma ryuburozi nubushakashatsi bwumutekano

Ubushakashatsi bwinshi bwuburozi bwerekanye ko methylcellulose ifite biocompatibilité nziza nuburozi buke. Ibisubizo by'ibizamini by’uburozi bukabije byerekanaga ko LD50 (dose yica median) yari hejuru cyane ugereranije n’amafaranga yakoreshejwe mu byongeweho ibiryo bisanzwe, byerekana umutekano muke. Mu bizamini by’ubumara bwigihe kirekire, imbeba, imbeba nizindi nyamaswa ntabwo byagaragaje ingaruka mbi mugihe cyo kugaburira igihe kirekire ku kigero kinini, harimo ingaruka nka kanseri, teratogenicite nuburozi bwimyororokere.

Byongeye kandi, ubushakashatsi bwa methylcellulose ku mara yumuntu nabwo bwarigishijwe cyane. Kubera ko idahumeka kandi ngo yinjizwemo, methylcellulose irashobora kongera ingano yintebe, igatera imbere mu mara, kandi ikagira inyungu zimwe na zimwe mu kugabanya impatwe. Muri icyo gihe, ntabwo iterwa na flora yo mu mara, bigabanya ibyago byo kubyimba cyangwa kubabara mu nda.

3. Amabwiriza

Ikoreshwa rya methylcellulose nk'inyongeramusaruro ryateganijwe ku isi hose. Nk’uko isuzuma ryakozwe na komite y’impuguke ihuriweho n’inyongeramusaruro y’ibiribwa (JECFA) ishami ry’umuryango w’abibumbye ryita ku biribwa n’ubuhinzi (FAO) n’umuryango w’abibumbye ryita ku buzima (OMS), ngo buri munsi (ADI) byemewe na methylcellulose "ntibisobanuwe neza ", byerekana ko ari byiza gukoresha muri dosiye isabwa.

Muri Amerika, methylcellulose yashyizwe ku rutonde nk’ibintu bisanzwe bizwi ko bifite umutekano (GRAS) n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA). Mu Muryango w’ubumwe bw’ibihugu by’Uburayi, ishyirwa mu byongeweho ibiryo E461, kandi ikoreshwa ryayo mu biribwa bitandukanye irasobanuwe neza. Mu Bushinwa, ikoreshwa rya methylcellulose naryo rigengwa n "" Ikigo cy’igihugu gishinzwe umutekano w’ibiribwa byongera ibiribwa "(GB 2760), gisaba kugenzura neza dosiye ukurikije ubwoko bwibiryo.
