Ko te Xylitol (CAS: 87-99-0) te tino reka o nga polyols katoa.He reka ano ki te sucrose, kaore he reka o muri, he haumaru mo te hunga mate huka.Ko te Xylitol he 40% iti ake nga kaarai i te huka.Na reira, i roto i te EU me te United States, ko te uara calorie e whakaaetia ana e nga tapanga kai ko te 2.4 kcal/g.I roto i nga tono whakatioataata, he pai te whakamahana o te taiao ki etahi atu polyols.Koia anake te kai reka e whakaatu ana i nga paanga anti-caries kaha me te kaha.Ko te Xylitol kua whakarōpūhia e te US Food and Drug Administration hei taapiri kai.
Ko te Xylitol he matū reka me te uara kai, he takawaenga noa o te warowaihā o te tangata.Ko te xylitol tauhokohoko ka puta mai i te tukatuka hohonu o nga hua ahuwhenua penei i te witi witi me te bagasse.He kai reka maori, hauora hoki.
Nga Mahi me nga Whakamahinga o Xylitol (CAS: 87-99-0)
1. Ki te whakaputa kapia, ngaungau kapia, toffee, monamona ngohengohe, tiēre, tiakarete, papa ngaungau me etahi atu mea, ka whakamatao i te korokoro, te horoi i nga niho me te anti-cariogenic.
2. Ko te mea hei whakakapi i te sucrose ki te tapiri atu ki te inu ngohengohe, te miraka, te taro, nga hua rongoa, te pihikete, te miraka tepe, te tami, te pāreti me te aha atu, kia roa ake ai te reka o te reka na te kore o te rewena i te rewena.
3. Ka taapirihia ki roto i nga hua whakapaipai me te toothpaste, kaore he ahua piri me te whakahauora.Ka taea e Xylitol te pupuri i te makuku me te whakapai ake i te kiri taratara rite ki te glycerin.
4. Ko te Xylitol, hei whakakapinga pai mo te kai reka mo te mate huka, ka taea te whakamahi whanui ki te inu wai, kawhe, miraka, taro, monamona me etahi atu kai kore huka.
5. Koia te take kino mo te moroiti me te kore e taea te rewena e te rewena.Ko te hanga kai me te Xylitol ka taea te pupuri mo te wa roa kaore he rongoa.
6. Ka taea e Xylitol te whakatairanga i te mahi o nga iroriki whakaora me te whakapai ake i te mate o te tinana.Ka taea e Xylitol te tango i te nui ake o te mahunga i era atu polyols, no reira he hauhautanga te reka o te kai me te xylitol me te pupuri i te reka o te kai taketake.
7. He pai ki te whakakapi i te sucrose, hei hanga rīhi pēnei i te poaka kawa me te reka, te ika ranei, he tino haumaru ki te hunga mate huka.Ko ta matou whakaaro kaua e neke ake i te 40g ia ra mo te pakeke me te haurua mo te tamaiti.
8, Te reka o te hauora: Ko te reka o te Xylitol o te sucrose, i tangohia mai i nga rauemi mata maori, he kai reka hauora taiao, ka taea te whakamahi i nga kai kore huka, te huka kore huka me etahi atu kai hauora.
9, Aukati i te mate hakihaki: Kaore e taea e Xylitol te whakauru i roto i te waha huakita FERMENTATION ma te whakamahi i nga mate niho, he pai rawa atu nga mahi aukati i nga mate niho i roto i nga mea reka katoa.Ka taea te whakamahi whanui ki nga momo hua tiaki waha.
10, Aukati i te huka toto: Xylitol me te kore e pa ki te paopaotanga huka i roto i te tinana, kaore e hiahia ki te whakatairanga, ka taea hoki ma te membrane pūtau, ka uru ki te whakahaere.Mo te tangata whai huka huka, he taapiringa kai, he awhina awhina.
11, Te whakapai ake i te mahi ate: Ka taea e Xylitol te whakatairanga i te whakahiato o te glycogen yuan, te whakaiti i te kai o te ngako me te pūmua i roto i te kiko ate, te tiaki me te whakapai i te ate, te whakapai ake i te mahi ate i roto i nga turoro me te mate ate me te ate ngako, te painga o te maimoatanga o te kakā o te sex o te kakā b, kakā b, kakā mau tonu me te ate cirrhosis whai pānga whakaora kitea, he pai tarukino pŭpŭ tauturu mate kakā pōauautanga o tūroro.
12, Taumahi mate taimaha: Xylitol whakaritea ki te huka granulated noa, he te painga o te rahinga iti o te wera, Xylitol kei anake 2.4 Calories ia karamu, 40% iti wera atu i te nuinga atu warowaihā, no reira ka taea te tono Xylitol ki nga momo kai whakaiti. taimaha, hei whakakapi mo te huka o te nui o te wera.
13, Whakapai ake i te mahi gastrointestinal: Ka taea e Xylitol te whakatairanga i te tipu o te bifidobacterium.Te whakatairanga i te tipu o te tipu intestinal whai hua, te whakapai ake i te mahi gastrointestinal, he mahi tino nui, he momo huanga taapiri whai hua.
14, Hygroscopicity, whakamahia ki te hanga etahi ahua iti, ngawari atu i te sucrose kia makuku, ngawari me te mo te wa roa, i te wa ano ki te whakaroa i te oranga o te kai, penei i te hanga keke, taro, aha atu. Ka taea te whakamahi hei a te whakatikatika maku o te akomanga whakapaipai, kaore he whakaohooho ki te kiri tangata.
15, Whakakaha i te waha: ka taea te kai te whakaputa i te ahua pai me te hauhautanga i roto i te waha, ka pai ake i muri i te mīti, ka taea te whakamahi i roto i te whakamarie o te inu makariri, te kai reka, te miraka, te kawhe, me era atu. Ka taea hoki te whakamahi i nga inu hauora, Ko nga rongoa korokoro, te tirikara mare, me etahi atu. Ka taea tonu te tapiri i te pepa, te tao, me etahi atu. Ko te reka o te kai.
16, Whakaroahia te oranga o te papa: Xylitol na te rewena FERMENTATION, he kino mo te reo moroiti moroiti, he roa te reka, kia roa ai tona oranga papa.
17, Kaua e whakaputa i te tauhohenga maillard Browning: Ko Xylitol ehara i te roopu aldehyde me te roopu ketone i roto i te hanganga, kaore te whakamahana e whakaputa i te tauhohenga maillard Browning, ka taea te hanga ki nga momo rereke o nga taonga tunu.
