Isticmaalka
Kaalmada Shaandhada: Wakiilka ka hortagga dubista, xidhaha; Wakiilka wax lagu qaso; Kala-baxa; Kala-baxa; Hagaajiyaha qaab-dhismeedka; Wakiilka qaro weynaynta; Wakiilka daaweynta biyaha. Waxaa qeexay EEC si loo nadiifiyo biirka. Sida ku cad GB 2760-96, waxaa loo arkaa gargaar wax lagu farsameeyo. Sida ku cad xeerarka EEC-HACSG, looma isticmaali karo cuntada dhallaanka. Sida wakiilka ka hortagga dubista, Shiinaha, waxaa loo oggol yahay in lagu isticmaalo dhadhanka budada ah iyadoo ugu badnaan la isticmaalo 50g/kg; waxaa sidoo kale loo isticmaali karaa jalaatada iyadoo ugu badnaan la isticmaalo 40g/kg; waxaa sidoo kale loo isticmaali karaa budada kareemka fudud iyo dufanka khudradda iyadoo ugu badnaan la isticmaalo 20.0g/kg. Marka kooxaha hydroxyl ee ku jira macromolecule-ka cellulose ay maraan falgallada esterification ama etherification, badeecooyin badan oo waxtar leh ayaa laga soo saari karaa. Esters-ka cellulose ee dhab ahaantii la isticmaalo waxaa ka mid ah: cellulose nitrate, cellulose acetate, cellulose acetate butyrate iyo cellulose xanthate. Ether-yada Cellulose waxaa ka mid ah: methyl cellulose, carboxymethyl cellulose, ethyl cellulose, hydroxyethyl cellulose, cyanoethyl cellulose, hydroxypropyl cellulose iyo hydroxypropyl methyl cellulose, iwm. Intaa waxaa dheer, waxaa jira waxyaabo isku dhafan oo ester-ether ah. Microcrystalline cellulose waxaa lagu dabaqi karaa warshadaha sida dharka, dharka, sameynta khamriga, cuntada, iyo sameynta waraaqaha.
Cellulose-ka Microcrystalline guud ahaan wuxuu leeyahay cufnaan hoose oo loogu talagalay alaabada la qaboojiyey ee la qaboojiyey iyo cufnaan sare oo loogu talagalay alaabada la buufiyey. Qoyaanka ku jira waa qiyaastii 5%. Cellulose-ka Microcrystalline waa la kala diri karaa laakiin kuma milmi karo biyaha, kuma milmi karo asiidhyada la miiray, dareerayaasha dabiiciga ah iyo saliidaha, wuu bararaa oo qayb ahaan wuu milmaa xalalka alkaline-ka ee la miiray. Budada cellulose-ka microcrystalline ee lagu kala firdhiyo biyaha waxay soo saartaa jel ama koollo cad oo hufan. Marka laga reebo kuwa aadka u milmay, waxay sii ahaanaysaa mid deggan sannado badan.
