D-(+)-Xylose (sonkorta alwaax) (CAS: 58-86-6), oo caadi ahaan loo yaqaan sonkorta alwaax, waa sokor 5-carbon ah oo dabiici ah (pentose) oo laga helay qaybta qani ku ah xylan ee hemicellulose, oo ku jirta unugga dhirta derbiyada iyo fiber.Xylitol waa macaane nafaqo leh.Qofka caafimaad qaba wuxuu soo saari karaa Xylitol ee jirka laftiisa, xitaa haddii uusan cunin wax kasta oo Xylitol ah.Dabeeciga, Xylitol wuxuu si ballaaran ugu jiraa noocyo badan oo miro iyo khudaar ah.Laakiin waxa ku jira waa mid aad u yar.Isticmaalka ganacsiga, Xylitol waxaa inta badan laga soo saaraa galleyda, bacaha sonkorta sonkorta, geed bjørk iyo wixii la mid ah.Waa macaane dabiici ah oo caafimaad qaba.Laga soo bilaabo muuqaalka, waa crystal cad oo u eg sonkor cad.Xylitol waa macaaneeyaha ugu macaan ee polyols-yada.Waxay leedahay dhadhan qabow oo soo cusboonaysiiso waxayna leedahay macaan la mid ah sukrose, laakiin kalooriga xylitol aad ayuu uga hooseeyaa sukrose, qiyaastii wuxuu la mid yahay gulukooska.Xylitol waa macaane rajo leh waana bedel ku habboon gulukoosta iyo sukrose.L-Arabinose waa budo crystalline cad oo leh dhadhan macaan iyo dhibic dhalaalaysa 154-158 ℃.Waxay si fudud ugu milmi kartaa biyaha iyo glycerol, wax yar bay ku milmi kartaa ethanol oo kuma milmi ether.Aad bay u deggan tahay xaaladda kulaylka iyo aashitada.Sida macaaneeye kaloriin yar, waxaa loo ansixiyay inay noqoto cuntada lagu daro caafimaadka caafimaadka leh ee Xafiiska Maraykanka ee Kormeerka Cunnada iyo Dawooyinka iyo Caafimaadka iyo Adeegyada Aadanaha ee Japan.Sidoo kale, waxaa oggolaaday cunto kheyraad cusub Waaxda Caafimaadka Shiinaha.
Hawlaha
1. D-(+)-Xylose sida macaane aan kaloriin ahayn, D-(+)-Xylose waxaa loo isticmaalaa sida antioxidant dufan, diyaarinta caafimaadka, alaabta ceeriin ee midabka karamell iyo udgoon kala duwan, iwm
2. D-(+)-Xylose waxa loo isticmaali karaa wax ka beddelka dhadhanka hilibka iyo habaynta cuntada.Waxa kale oo lagu dabaqi karaa sida alaabta ceeriin ee nuxurka hilibka iyo antioxidant.
Codsiyada
1. Si loo soo saaro xanjo, xanjo, toffee, nacnac jilicsan, jelly, shukulaatada, kaniiniga la calaliyo iyo wixii la mid ah, waxay qaboojin karaan cunaha, nadiifin karaan ilkaha waxayna noqon karaan kuwo ka hortaga cariogenic.
2. Inaad noqoto halkii sukrose lagu daro cabitaanka fudud, caanaha, rootiga, khudaarta la ilaaliyo, buskudka, yogurt, macaanka, boorash iyo iwm, si aad u sii dheeraato & dhadhanka macaan ee macaan sababtoo ah khamiir la'aantiisa.
3. Waxaa lagu daray alaabta la isku qurxiyo iyo daawada cadayga, ma laha dareen dhegdheg ah iyo soo celin.Xylitol waxay ilaalin kartaa qoyaanka waxayna hagaajin kartaa maqaarka qallafsan sida glycerin.
4. Inaad si fiican ugu badasho sukrose, si aad u samayso suxuunta sida dhanaanka & hilibka doofaarka ama kalluunka, aad ugu badbaado dadka macaanka qaba.Soo jeedintayadu kama badna 40g/maalintii dadka waaweyn iyo kala bar ilmaha.
