Ko te D-(+)-Xylose (Wood Sugar) (CAS: 58-86-6), e kiia nei ko te huka rakau, he huka 5-waro (pentose) taiao i riro mai i te wahanga xylan-nui o te hemicellulose, kei roto i te tipu tipu. taiepa me te muka.Ko te Xylitol he kai reka matūkai.Ka taea e te tangata hauora te whakaputa Xylitol i roto i te tinana ake, ahakoa kaore ia e kai i nga hua Xylitol.I roto i te taiao, he nui te Xylitol i roto i te maha o nga momo hua me nga huawhenua.Engari he iti rawa te ihirangi.Mo te whakamahi arumoni, ko te Xylitol te nuinga o te wa ka hangaia mai i te kanga kanga, te huka huka, te rakau birch me etahi atu.He kai reka maori, hauora hoki.Mai i te ahua, he karaihe ma, he rite ki te huka ma.Ko Xylitol te kai reka rawa atu i waenga i nga polyols.He hauhautanga, he hou te reka, he rite tonu te reka ki te sucrose, engari he iti ake te kaarai o te xylitol i te sucrose, he rite ki te hukahuka.Ko te Xylitol he kai reka, he tino pai hei whakakapi mo te huka me te sucrose.Ko te L-Arabinose he paura tioata ma me te reka reka me te rewa o te 154-158 ℃.He ngawari ki te wairewa ki te wai me te glycerol, he paku wairewa ki te waiwaro, kaore e memeha ki te etera.He tino pumau i raro i te ahua o te wera me te waikawa.I te mea he kai reka iti-calorie, kua whakaaetia kia waiho hei taapiri kai hauora e te Tari Tiaki Kai me te Taakaro me te Tari Hauora me te Tari Tangata o Hapani.Ano, kua whakamanahia he kai rauemi hou e te Tari Hauora o Haina.
Nga Mahi
1. D-(+)-Xylose hei kai reka kore-calorie, D-(+)-Xylose e whakamahia ana hei antioxidant ngako, te whakarite rongoa, nga rauemi mata o te karamere me nga momo kakara, aha atu
2. D-(+)-Ka taea te whakamahi i te Xylose hei whakarereke reka i roto i te kai me te tukatuka kai.Ka taea hoki te whakamahi hei rauemi mata o te ngako kai me te antioxidant.
Nga tono
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. 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.
