I-Xylose iqukethe amaphesenti angekho ngaphansi kwamaphesenti angu-98.0 futhi angabi ngaphezu kwamaphesenti angu-102.0 we-C5H10O5, abalwe ngokomisiwe.
Ukupakisha nokugcina-Londoloza ezitsheni eziqinile ekamelweni lokushisa elilawulwayo.
Amazinga ereferensi we-USP <11>-
USP Fructose RS
USP Xylose RS
Umbala wesixazululo-Isixazululo esisanda kulungiswa (1 ku-10) sicacile futhi asinambala.
Ukuhlonza-
A: I-Infrared Absorption <197A>.
B: Isikhathi sokugcinwa sesiqongo esikhulu ku-chromatogram yokulungiselelwa kwe-Assay sihambisana naleso esiku-chromatogram yokulungiselelwa Okujwayelekile, njengoba kutholwe ku-Assay.
Ukuzungezisa okuqondile <781S>: phakathi kuka-+18.2° kanye no-+19.4°.
Isixazululo sokuhlola: 100 mg mL ngayinye, ku-0.012 N ammonium hydroxide.
Ukulahlekelwa ekumisweni <731>-Yomisa 2 g kuya ku-5 g ngengcindezi engeqile ku-50 mm we-mercury ku-60° ukuya esisindweni esingaguquki, umsinga womoya omisiwe udluliswa kuhhavini ngesikhathi sokumisa ukuze ukhiphe umhwamuko wamanzi: uyalahlekelwa. hhayi ngaphezu kuka-0.1% wesisindo sayo.
Izinsalela ekushiseni <281>: hhayi ngaphezu kuka-0.05%.
I-ayoni <241>-Chaza u-2.0 g ku-45 mL wamanzi, bese wengeza u-2 mL we-hydrochloric acid: umkhawulo ngu-5 ppm
Izinsimbi ezinzima <231>-Chaza u-2.0 g emanzini ukuze wenze u-25 mL wesixazululo: umkhawulo ngu-0.001%.
Ukuhlanzeka kwe-Chromatographic-Sebenzisa i-chromatogram yokulungiselelwa kwe-Assay, etholwe njengoba kuqondiswe ku-Assay.Bala iphesenti lokungahlanzeki ngakunye ngakunye, ngaphandle kwanoma yiziphi iziqongo zokuncibilika, engxenyeni ye-Xylose ethathiwe:
100(ri / rS)
lapho ri kuyimpendulo yokungcola komuntu ngamunye;futhi i-rS iyisamba sazo zonke izimpendulo ku-chromatogram: akutholakali ngaphezu kuka-1.0% wanoma yikuphi ukungcola komuntu ngamunye, futhi isamba sakho konke ukungcola okukodwa okutholiwe asingaphezu kuka-2.0%.
Isivivinyo-
Isigaba seselula-Sebenzisa ingxube ekhishwe i-acetonitrile namanzi (75:25).
Isixazululo sokufaneleka kwesistimu-Lungiselela isixazululo esigabeni Seselula, esiqukethe cishe u-10 mg we-USP Xylose RS kanye no-0.2 mg we-USP Fructose RS nge-mL ngayinye.
Ukulungiselela okujwayelekile-Chaza isamba esikalwe ngokunembile se-USP Xylose RS esigabeni Seselula ukuze uthole isixazululo esinokugxila okwaziwayo okungaba ngu-10 mg nge-mL ngayinye.
Ukulungiselela i-Assay-Dlulisa cishe u-100 mg we-Xylose, ukalwe ngokunembile, uye ku-10-mL ye-volumetric flask, ncibilika futhi uhlambulule ngesigaba Seselula siye kuvolumu, bese uxuba.
Isistimu ye-Chromatographic (bona i-Chromatography <621>)-I-chromatograph ewuketshezi ifakwe umtshina ongu-192-nm kanye nekholomu engu-4.6-mm × 15-cm equkethe ukupakisha i-L8.Izinga lokushisa lekholomu ligcinwa ku-30 °, futhi izinga lokugeleza lingaba ngu-2 mL ngomzuzu.I-Chromatograph isixazululo sokufaneleka Kwesistimu, futhi urekhode izimpendulo eziphezulu njengoba kuqondiswe Inqubo: ukulungiswa, R, phakathi kweziqongo ze-xylose ne-fructose akukhona ngaphansi kuka-2.0.Ukuchezuka okujwayelekile okuhlobene kwemijovo eyimpinda akukho ngaphezu kuka-2.0%.
Inqubo-Ngokuhlukile jova amavolumu alinganayo (cishe u-25 µL) wokulungiselelwa kwe-Assay kanye nokulungiswa Okujwayelekile ku-chromatograph, rekhoda ama-chromatogram, futhi ulinganise izimpendulo zeziqongo ezinkulu.Bala inani, ngo-mg, le-C5H10O6, engxenyeni ye-Xylose ethathwe ifomula:
10C(rU / rS)
lapho u-C eyingqikithi, ngo-mg nge-mL ngayinye, ye-USP Xylose RS ekulungiseleleni Okujwayelekile;futhi i-rU kanye ne-rS yizimpendulo eziphezulu ezitholakala ekulungiselelweni kwe-Assay nasekulungiseleleni Okujwayelekile, ngokulandelanayo.
Iphakheji: Isikhwama se-Aluminium foil, 25kg/bag, 25kg/Cardboard Drum, noma ngokwezidingo zekhasimende.
Isimo Sesitoreji:I-Hygroscopic.Gcina ezitsheni ezivaliwe endaweni epholile, eyomile futhi engenamoya kude nezinto ezingahambelani.Vikela ekukhanyeni nakumswakama.Akuhambisani nama-oxidizing agents aqinile.

I-D-(+)-Xylose (Ushukela Wokhuni) (CAS: 58-86-6), ovame ukubizwa ngokuthi ushukela wokhuni, ushukela wemvelo we-5-carbon (pentose) otholakala engxenyeni ecebile nge-xylan ye-hemicellulose, ekhona kuseli yezitshalo. izindonga kanye fibre.I-Xylitol iyi-sweetener yezakhi.Umuntu onempilo angakwazi ukukhiqiza i-Xylitol emzimbeni ngokwakhe, ngisho noma engadli noma yimiphi imikhiqizo ye-Xylitol.Ngokwemvelo, i-Xylitol itholakala kakhulu ezinhlotsheni eziningi zezithelo nemifino.Kodwa okuqukethwe kuncane kakhulu.Ukuze isetshenziselwe ukuhweba, i-Xylitol imvamisa ukukhiqizwa kusuka ku-corncob, umoba bagasse, isihlahla se-birch nokunye.Kuyi-sweetener engokwemvelo futhi enempilo.Ngokwendlela ebukeka ngayo, iyikristalu emhlophe futhi ibukeka njengoshukela omhlophe.I-Xylitol iyi-sweetener emnandi kakhulu phakathi kwama-polyols.Inokunambitheka okupholile futhi okuqabulayo futhi inobumnandi obufana ne-sucrose, kodwa ikhalori ye-xylitol iphansi kakhulu kune-sucrose, cishe ilingana ne-glucose.I-Xylitol iyi-sweetener ethembisayo futhi ithatha indawo ephelele ye-glucose ne-sucrose.I-L-Arabinose i-crystalline powder emhlophe enokunambitheka okumnandi nendawo encibilikayo engu-154-158℃.Incibilika kalula emanzini ne-glycerol, inyibilika kancane ku-ethanol futhi ayincibiliki ku-ether.Izinzile kakhulu ngaphansi kwesimo sokushisa ne-asidi.Njengesishukela esinekhalori ephansi, sigunyazwe ukuthi sibe isithasiselo sokudla esinempilo yi-American Bureau of Food and Drug Supervision and Health and Human Services Department of Japan.Futhi, kugunyazwe ukudla okusha kwensiza nguMnyango Wezempilo waseChina.
Imisebenzi
1. I-D-(+)-Xylose njenge-sweetener engeyona ikhalori, i-D-(+)-Xylose isetshenziswa njenge-antioxidant yamafutha, ukulungiswa kwezokwelapha, impahla eluhlaza yombala we-caramel kanye nephunga elimnandi, njll.
2. I-D-(+)-Xylose ingasetshenziswa njengesilungisi se-flavour ekucubunguleni inyama kanye nokudla.Ingasetshenziswa futhi njengempahla eluhlaza ye-essence yenyama kanye ne-antioxidant.
Izinhlelo zokusebenza
1. Ukukhiqiza ushingamu, ushingamu, ithofi, uswidi othambile, ujeli, ushokoledi, ithebhulethi yokuhlafuna nokunye, kungapholisa umphimbo, ukuhlanza amazinyo futhi kube anti-cariogenic.
2. Esikhundleni se-sucrose ukufaka esiphuzweni esithambile, ubisi, isinkwa, izithelo ezigciniwe, amabhisikidi, iyogathi, ujamu, iphalishi nokunye, ukugcina ukunambitheka okumnandi okude & okungcono ngenxa yokungavutshelwa kwayo imvubelo.
3. Kwengezwe kumkhiqizo wezimonyo kanye nomuthi wokuxubha, akukho ukuzwa okunamathelayo nokuqabulayo.I-Xylitol ingagcina umswakama futhi ithuthukise isikhumba esimaholoholo esifana ne-glycerin.
4. Ukusebenzisa kahle i-sucrose, ukwenza izitsha ezifana nengulube emuncu noma enoshukela noma inhlanzi, ephephile kakhulu kwabanesifo sikashukela.Isiphakamiso sethu asikho ngaphezu kwama-40g / ngosuku kumuntu omdala nengxenye yengane.
