1. Uburyo bwo gukuramo butaziguye

Xylitol yatandukanijwe bwa mbere n’igiti cy’ibiti byatewe n’umuhanga w’umudage witwa Hermann Emil Fischer mu 1890. Ubusanzwe Xylitol ibaho mu bikoresho fatizo bishingiye ku bimera muri kamere, nka strawberry, plum yumuhondo, kawuseri, nizindi mbuto n'imboga (ibiro 300-935 mg / 100 g byumye). Gukuramo ibishishwa birashobora gukoreshwa mu gukuramo mu buryo butaziguye xylitol mu bikoresho bishingiye ku bimera, ariko ibirimo xylitol biri hasi mu bikoresho bishingiye ku bimera nkimbuto n'imboga. Nubwo ibirimo xylitol biri mubibabi bya apicot biruta ibindi bikoresho bishingiye ku bimera, kandi ibirimo xylitol mu kibabi kibisi bingana na 1% byuburemere bwumye, kubikuramo xylitol mu buryo butaziguye bisaba ibikoresho kabuhariwe, bitwara ingufu nini, kandi bifite amafaranga menshi yo gukora.

2. Uburyo bwa synthesis

Mu myaka ya za 70, Finlande niyo yambere yakoresheje chromatografiya itandukanya D-xylose na hemicellulose zitandukanye. Nyuma, D-xylose yagabanutse kuri xylitol munsi yubushyuhe bwinshi, umuvuduko mwinshi, hamwe na hydrogène catalizike, hanyuma itera imbere muburyo bwo gukora inganda za xylitol.

Xylitol irashobora kugabanuka muburyo butaziguye D-xylose ikoresheje synthesis ya chimique, cyangwa ikomatanyirizwa muri biomass ya lignocellulosique ikungahaye kuri xylose. Umusaruro wa xylitol haba mu gihugu ndetse no mu mahanga ukunze gukoresha ibikoresho fatizo bikungahaye kuri pentose polysaccharide, nk'ibyatsi by'ingano bisanzwe, ingano, ububiko bw'ibigori, ibigori by'ibigori, n'ibindi, bigenwa na hydrolysis ya aside (nka HCI, HSO), hanyuma bigasukurwa mu bice bya hemicellulose. Mubikorwa bya catalizator, xylose ihura na hydrogenation reaction.

3. Uburyo bwo guhindura ibinyabuzima

Inzira ya biotechnologiya ikubiyemo hydrolysis yimyanda yubuhinzi irimo isukari ya pentose (nkibigori byibigori, bagasse, na olive pomace) hamwe na aside ya dilute kugirango ibone xylose hydrolyzate, hanyuma igabanywa kuri xylitol na mikorobe. Gukoresha mikorobe ya fermentation ya hemicellulose hydrolyzate kugirango ikore xylitol ifite ibyiza byimiterere yoroheje, imikorere yoroshye, kubungabunga ibidukikije, umwanda muke ugereranije, hamwe nubwiza bwibicuruzwa byizewe, bigatuma bishoboka ko ubundi buryo buhendutse bwo kubona iyi polyol.

Igikorwa cyo gukora xylitol ni ndende, ariko inzira nyinshi zingenzi zigomba gufatwa kugirango harebwe ubuziranenge bwibicuruzwa bya xylitol niterambere ryiterambere. Ibi bizwi nkibikorwa byo gufatanya. Iyo inzira nyinshi zingenzi zirangiye, ingingo zingenzi zumusaruro wa xylitol zirafashwe.
