Methylcellulose (MC)bụ ngwakọta sitere na cellulose nke a na-ejikarị eme ihe na nri, ọgwụ, ihe ịchọ mma na ụlọ ọrụ ndị ọzọ. Ọ bụ mmiri-soluble cellulose ewepụtara na ụfọdụ ndim, gelling, emulsification, nkwusioru na ndị ọzọ Njirimara.
Njirimara kemịkalụ na ụzọ mmepụta nke methylcellulose
A na-enweta Methylcellulose site na mmeghachi omume cellulose (ihe bụ isi ihe na-emepụta ihe na osisi) na onye na-emepụta methylating (dị ka methyl chloride, methanol, wdg). Site na mmeghachi omume methylation, ìgwè hydroxyl (-OH) nke cellulose na-anọchi anya otu methyl (-CH3) iji mepụta methylcellulose. Ọdịdị nke methylcellulose dị ka nke mbụ cellulose, ma n'ihi mgbanwe nhazi ya, ọ nwere ike gbazere na mmiri iji mepụta ngwọta viscous.

Ya mere, methylcellulose nwere obere toxicity na ọ dịghị ihe doro anya na-emerụ ahụ mmadụ.
Mmetụta na ahụ mmadụ
Methylcellulose anaghị etinyekarị aka na ahụ. Ọ nwere ike inye aka kwalite peristalsis intestinal ma nyere aka belata nsogbu afọ ntachi. Dị ka eriri nri, ọ na-arụ ọrụ nke moisturize na ichekwa eriri afọ, ọ pụkwara ọbụna ịhazi ọkwa shuga dị n'ọbara. Otú ọ dị, nnukwu oriri nke methylcellulose nwere ike ịkpata ahụ erughị ala nke eriri afọ, dị ka flatulence ma ọ bụ afọ ọsịsa. Ya mere, ọ dị ezigbo mkpa iji ezigbo methylcellulose mee ihe mgbe ị na-eji ya dị ka mgbakwunye.
