1.Ko te kapia Xanthan he rauemi polysaccharide te taumaha irapoi teitei e polymerized mai i te waeine kotahi me te huka Molecular e 5 hei waeine.Ko ia waeine he 2 ngota ngota ngota huka, 2 ngota ngota o te mannose me te 1 ngota ngota ngota glucuronic acid.Ko tana mekameka matua ko te β- Ko te Glucose e hono ana e te herenga 1,4-glycosidic.He rite tonu te hanga o nga ngota ngota ngota e 2 ki to te cellulose.E 2 ngota ngota o te mannose me te 1 ngota ngota o te waikawa glucuronic kei runga i te C3 o te hukahuka hei hanga mekameka taha.He roopu taha waikawa pyruvic me te waikawa carboxylic kei te mekameka taha.Na te mea kei roto i tana mekameka taha he roopu waikawa, ka whakaatuhia he polyanion ki roto i te wairewa wai, ka hanga he hanganga toru-toru-toru o te kapia xanthan: ko te mekameka taha me nga anion e hau ana te mekameka matua ki te hanga i te hanga helical, a ko nga ngota ngota ka hanga i te pae rua. helix na roto i nga here hauwai, i te mea e mau tonu ana te hangahanga hikoi taurua e nga here ngoikore kore, ka hanga he "whakawaewae helical ribbon super here".Ko tana mahi ahurei e pa ana ki te waikawa pyruvic kei roto.Ko te tikanga, ka taea te whakamahi i te waikawa pyruvic i roto i te kapia xanthan ki te ine i tana mahi.

2.Typical rheological āhuatanga, viscosity tiketike i te kukū iti, parenga wera, ātete waikawa, ātete alkali, ātete hydrolysis enzymatic, hototahi, memeha, marara, pupuri wai.

3.Solubility te wairewa i roto i te wai, insoluble i roto i te waihā (ot-42).Me mau ki te 300ml wai mo te whakamatautau hanga ra, tuu ki roto i te ipurau 400ml, whakamahana ki te 80 ℃, me te tapiri i te 1.5 karamu o te tauira me te 1.5 karamu o te paura karagenan i raro i te whakaoho kaha.Oho kia puta ra ano te wairewa, katahi ka whakaoho tonu mo te 3chemicalbook0min.I te wa o te ranu, kaua te pāmahana wai e iti iho i te 60 ℃, mutu te whakaranu, ka whakamatao i te pāmahana rūma neke atu i te 2H.Ina he iti iho te mahana i te 40 ℃, me hanga he rapa pakeke penei i te ra, engari kare e hanga he reera penei mena ko te tauira anake ka whakamahia hei utu mo te otinga whakahaere 1% kua rite i te tikanga me te karagenan.

Taupānga

1. I roto i te keri o te ahumahi hinu, ka taea e te 0.5% te otinga xanthan glue te pupuri i te paheketanga o te wai keri wai me te whakahaere i ona ahuatanga rheological, na te mea he iti rawa te paheketanga o te moka hurihuri tere tere, he nui te whakaora i te kaha. .Heoi, ka mau tonu te pokey i roto i te wahanga keri pateko, e whai waahi ana ki te aukati i te tiango o te pakitara poka me te ngawari ki te tapahi kirikiri mai i te puna.

2. I roto i te ahumahi kai, he pai ake i nga taapiri kai o naianei penei i te gelatin, CMC, kapia rimurapa me te pectin.Ko te taapiri i te 0.2% - 1% ki te wai hua ka pai te piri o te wai hua, te reka pai, me te whakahaere i te kuhu me te rere;Hei taapiri mo te parāoa, ka taea e te pukapuka matū te hanga parāoa kia u, kia maeneene, kia penapena te wa me te whakaiti i te utu;Ma te whakamahi i te 0.25% i roto i te parai paraoa, te whakakii kai me te hukapapa ka taea te whakanui ake i te reka me te reka, te maeneene i te whakaritenga o nga hua, te roa o te oranga o te papa, me te whakapai ake i te pumau o nga hua ki te whakamahana me te mīti;I roto i nga hua miraka kau, ko te taapiri i te 0.1% - 0.25% ki te aihikirimi ka taea te mahi tino pai;Ka taea e ia te whakarato i te mana pokey pai i roto i te kai kēne, a ka taea te whakakapi i tetahi wahi o te māngaro.Ka taea e tetahi waahanga o te kapia xanthan te whakakapi i te 3 ~ 5 nga waahanga o te maaka.I taua wa ano, kua whakamahia nuitia te kapia xanthan ki roto i te monamona, nga mea kakara, te kai tio me te kai wai.
