I-D-(+)-Xylose (i-Wood Sugar) (i-CAS: i-58-86-6), ebizwa ngokuba yi-sugar yomthi, yindalo ye-5-carbon yeswekile (pentose) efunyenwe kwinxalenye ye-xylan-rich ye-hemicellulose, ekhoyo kwiseli yesityalo. iindonga kunye nefayibha.I-Xylitol yi-sweetener yezondlo.Umntu onempilo unokuvelisa i-Xylitol emzimbeni ngokwakhe, nokuba akatyi nayiphi na imveliso ye-Xylitol.Ngokwendalo, iXylitol ifumaneka kakhulu kwiintlobo ezininzi zeziqhamo kunye nemifuno.Kodwa umxholo uncinci kakhulu.Ukusetyenziswa kwezorhwebo, iXylitol ihlala iveliswa kwi-corncob, iswekile bagasse, umthi webirch njalo njalo.Yinto yendalo kunye nenempilo sweetener.Ukusuka kwinkangeleko, i-crystal emhlophe kwaye ibonakala njengeswekile emhlophe.I-Xylitol sesona siswiti siswiti phakathi kweepolyols.Inobumnandi obupholileyo kunye nokuhlaziya kwaye inobumnandi obufana ne-sucrose, kodwa i-calory ye-xylitol iphantsi kakhulu kune-sucrose, malunga ne-glucose.I-Xylitol yi-sweetener ethembisayo kwaye ithatha indawo efanelekileyo yeglucose kunye ne-sucrose.I-L-Arabinose ngumgubo omhlophe wekristale onencasa emnandi kunye nendawo yokunyibilika ye-154-158 ℃.Inyibilika ngokulula emanzini nakwi-glycerol, inyibilika kancinane kwi-ethanol kwaye ayinyibiliki kwi-ether.Izinzile kakhulu phantsi kwemeko yobushushu kunye ne-asidi.Njenge-calorie esezantsi isweetener, ivunyiwe ukuba ibe sisongezo sokutya okunempilo yi-American Bureau of Food and Drug Supervision and Health and Human Services Department of Japan.Kwakhona, kugunyaziswe ukutya okutsha kwiSebe lezeMpilo laseTshayina.
Imisebenzi
1. I-D-(+) -Xylose njenge-sweetener engeyona ikhalori, i-D-(+) -Xylose isetyenziswe njenge-antioxidant yamafutha, ukulungiswa kwezonyango, izinto eziluhlaza zombala we-caramel kunye nephunga elimnandi, njl.
2. I-D-(+)-Xylose ingasetyenziswa njenge-flavour modifier kwinyama kunye nokulungiswa kokutya.Inokuthi isetyenziswe njengezinto eziluhlaza zenyama kunye ne-antioxidant.
Usetyenziso
1. Ukuvelisa itshungama, itshungama, itofi, iilekese ezithambileyo, ijeli, itshokolethi, icwecwe lokuhlafuna kunye nokunye, unokupholisa umqala, ucoce amazinyo kwaye ube ne-anti-cariogenic.
2. Endaweni ye-sucrose yokongeza kwisiselo esithambileyo, ubisi, isonka, iziqhamo ezigciniweyo, ibhiskithi, iyogathi, ijam, isidudu njalo njalo, ukugcina incasa emnandi nengcono ngenxa yokungavundisi kwayo yigwele.
3. Ifakwe kwimveliso ye-cosmetic kunye ne-toothpaste, akukho mvakalelo yokuncamathela kunye nokuhlaziya.I-Xylitol inokugcina ukufuma kwaye iphucule ulusu olurhabaxa olufana ne-glycerin.
4. Ukuba endaweni elungileyo endaweni ye-sucrose, ukwenza izitya ezifana nenyama yehagu emuncu & neswiti okanye intlanzi, ikhuseleke kakhulu kubantu abanesifo seswekile.Ingcebiso yethu ayikho ngaphezu kwe-40g / ngosuku kumntu omdala kunye nesiqingatha somntwana.
