AKWỤKWỌ NDỊ MMADỤ GELATIN na swiiti dị nro
Gelatin bụ gel bụ isi nke a na-eji eme swiiti na-agbanwe gummy n'ihi na ọ na-enye swiiti dị nro ihe na-agbanwe agbanwe nke ukwuu.N'ime usoro mmepụta swiiti dị nro, mgbe ngwọta gelatin dị mma na 22-25 ℃, gelatin na-aghọ ihe siri ike.Dị ka àgwà ya si dị, a na-agwakọta ihe ngwọta gelatin na sirop ma wụsa ya n'ụdị mgbe ọ na-ekpo ọkụ.Mgbe jụrụ oyi, enwere ike ịmepụta ụdị jelii gelatin.
Njirimara ngwa pụrụ iche nke gelatin bụ mgbanwe ọkụ.Ngwaahịa nwere gelatin nọ na ọnọdụ ngwọta mgbe ọ na-ekpo ọkụ, wee ghọọ ọnọdụ oyi kpọnwụrụ mgbe ọ jụrụ.N'ihi na mgbanwe ngwa ngwa a nwere ike imegharị ọtụtụ ugboro, njirimara ndị bụ isi nke ngwaahịa anaghị agbanwe ma ọlị.N'ihi ya, nnukwu uru nke gelatine etinyere na swiiti jelii bụ na ọgwụgwọ ngwọta dị oke mfe.Ngwaahịa ọ bụla gelled sitere na ntụ ntụ na ọdịdị ọ bụla nwere ntụpọ nwere ike ikpo ọkụ ma gbasasịa ya na 60 ℃-80 ℃ tupu emegharịa ya na-enweghị emetụta àgwà ya.
Gelatin ọkwa nri isa eke protein nwere dissociable carboxyl na amino otu na molekul yinye.Ya mere, ọ bụrụ na usoro ọgwụgwọ ahụ dị iche, ọnụ ọgụgụ nke carboxyl na amino dị iche iche na agbụ molekụla ga-agbanwe, nke na-ekpebi ọkwa nke ebe isoelectric nke gelatin.Mgbe uru pH nke swiiti jelii dị nso na ebe isoelectric nke gelatin, ebubo ndị dị mma na nke na-adịghị mma na-ekewapụ na agbụ molecular gelatin hà nhata, protein ahụ na-aghọkwa nke kwụsiri ike na gelatinous.Ya mere, a na-atụ aro ka a họrọ ebe isoelectric nke gelatin pụọ na uru pH nke ngwaahịa ahụ, n'ihi na uru pH nke mkpụrụ osisi gelatin jelii swiiti na-abụkarị n'etiti 3.0-3.6, ebe ebe isoelectric nke acid gluu na-adịkarị elu, n'etiti. 7.0-9.5, yabụ gluu acid kacha adabara.
Ka ọ dị ugbu a, Gelken na-enye gelatin oriri nke kwesịrị ekwesị maka imepụta swiiti dị nro.Ike jelii bụ 180-250 oge ntoju.Nke dị elu nke ike jelii, nke ka mma na ike siri ike na elasticity nke ngwaahịa ndị a na-enye.A na-ahọrọ viscosity n'etiti 1.8-4.0Mpa.s dịka ike jelii siri dị.
