1. Habka soo saarista tooska ah

Xylitol ayaa markii ugu horreysay laga soocay jilif geedo geedo ah oo uu sameeyay saynisyahan Jarmal ah Hermann Emil Fischer 1890. Xylitol si dabiici ah ayaa ka jira alaabta ceeriin ee dhirta ku salaysan ee dabiiciga ah, sida strawberries, plums jaalaha ah, cauliflower, iyo miraha kale iyo khudaarta (300-935 mg / 100 g miisaanka qalalan). Soo saarista dareeraha waxaa loo isticmaali karaa in si toos ah loo soo saaro xylitol laga soo saaro alaabta dhirta ku salaysan, laakiin waxa ku jira xylitol waa ku yar yahay alaabta dhirta ku salaysan sida miraha iyo khudaarta. Inkasta oo maadada xylitol ee khudaarta khudaartu ay ka sarreyso qalabka kale ee dhirta ku salaysan, iyo waxa ku jira xylitol ee plums cagaaran waxay ka dhigan tahay qiyaastii 1% miisaanka qalalan, si toos ah xylitol iyaga ka soo saara waxay u baahan yihiin qalab gaar ah, waxay isticmaashaa tamar aad u badan, waxayna leedahay kharashyo badan oo wax soo saar ah.

2. Habka isku dhafka kiimikada

Sannadihii 1970-aadkii, Finland waxay ahayd tii ugu horreysay ee adeegsata chromatography si ay u kala saarto D-xylose iyo hemicelluloses-ka alwaaxyo ee kala duwan. Ka dib, D-xylose waxaa lagu dhimay xylitol hoostiisa heerkul sare, cadaadis sare, iyo catalysis hydrogen, oo loo sameeyay habka wax soo saarka xylitol warshadaha.

Xylitol si toos ah ayaa loogu dhimi karaa D-xylose saafi ah iyada oo loo marayo isku-dhafka kiimikaad, ama laga sameeyay baayomass lignocellulosic qani ku ah xylose. Soo saarista xylitol gudaha iyo dibadaba waxay inta badan isticmaashaa alaabta ceeriin ee hodanka ku ah pentose polysaccharides, sida cawska qamadiga dabiiciga ah, qamadiga, shooladda galleyda, galleyda, iwm, kuwaas oo lagu sii daaweeyay hydrolysis acid (sida HCI, HSO), ka dibna laga nadiifiyo jajabyada hemicellulose. Marka la eego ficilka kicinta, xylose-ku wuxuu maraa falcelinta hydrogenation.

3. Habka isbeddelka nafleyda

Dariiqa bayotechnoolajiyada waxa ku lug leh hydrolysis ee qashinka beeraha oo ay ku jiraan sonkorta pentose (sida galleyda, bagaaska, iyo pomace saytuunka) oo leh aashito badhxan si loo helo xylose hydrolysate, kaas oo markaa lagu yareeyo xylitol by microorganisms. Isticmaalka halsano microbial of hemicellulose hydrolyzate si ay u soo saaraan xylitol leeyahay faa'iidooyinka xaaladaha falcelinta khafiifka ah, hawlgalka fudud, saaxiibtinimo deegaanka, wasakh yar qaraabo, iyo tayada alaabta la isku halayn karo, taasoo ka dhigaysa hab kale oo qiimo jaban iman kara si loo helo polyol this.

Habka wax soo saarka xylitol waa mid aad u dheer, laakiin dhowr habab oo muhiim ah waa in la qabtaa si loo hubiyo tayada alaabta xylitol iyo horumarka habsami leh ee wax soo saarka. Tan waxaa loo yaqaan habka iskaashiga. Marka dhowr hannaan oo muhiim ah la dhammeeyo, qodobbada muhiimka ah ee wax-soo-saarka xylitol ayaa la fahmayaa.
