Kedu ihe bụ microcrystalline cellulose?

Microcrystalline cellulose (MCC), nke kachasị nke β- polysaccharide kwụ ọtọ jikọtara ya na njikọ 1,4-glucoside [1] bụ ntụ ntụ na-acha ọcha, na-enweghị isi na enweghị ụtọ nke nwere ezigbo mkpirisi mkpirisi mkpirisi mkpanaka ma ọ bụ ntụ ntụ. nke nwere ike na-aga n'enweghị ihe ọ bụla na hydrolyze eke cellulose na njedebe ogo nke polymerization (LODP) mgbe itucha acid hydrolysis.
N'ozuzu eriri osisi, microcrystalline cellulose bụ ihe dịka 70%, na 30% nke ọzọ bụ amorphous. A na-eji microcrystalline cellulose eme ihe n'ọtụtụ ebe na ọgwụ, ihe ịchọ mma, nri na ụlọ ọrụ ndị ọzọ. Dị iche iche urughuru size na mmiri ọdịnaya nwere dị iche iche e ji mara na ngwa nso.

Ọrụ nke microcrystalline cellulose

Microcrystalline cellulose nwere ike ịkwado ụfụfụ na emulsion, karịsịa n'oge nhazi okpomọkụ dị elu; Akpụ gel na ude ude; Imeziwanye nguzogide okpomọkụ nke pectin na starch gel; Meziwanye adhesion; Dochie abụba na mmanụ ma jikwaa uto kristal ice. Ihe kpatara microcrystalline cellulose nwere ike ime ka emulsion na ụfụfụ kwụsị bụ na a na-etinye microcrystalline cellulose na interface ahụ ma na-ewusi ihe mkpuchi ihu ókè.
