Ko te Karageenan te mea rongonui mo te hanga paura tiēre karagenan
Kupu Whakataki
Ko te Karageenan te mea rongonui mo te hanga paura tiēre karagenan. Ko Carrageenan te whanau o te polysaccharides i tangohia mai i te kauri whero whero. Ka whakamahia hei tiikiri, hei whakapakeke, hei whakapumau i roto i te tini o nga tono kai me te inu. Ka taea te whakamahi Karagenan hei whakaroa me te whakapumau i roto i nga kai tukatuka me nga hua heihei.
Carrageenan, he whakauru maha i tangohia mai i nga pukohu whero e hauhaketia ana i te moana, e whakamahia nuitia ana hei kaikawe reera, hei whakamatao, hei whakapumau i nga waahanga kai, penei i te kai, te tiēre, te aihikirimi, me te purini. Ko te nama taapiri kai a te pakeha mo tena ko E407 me E407a (me te ihirangi cellulose). Ko te tikanga, he haumaru, he taiao, he vegan, he hara, he kosher me te gluten kore.

Taupānga
He kaha te pumau a Carrageenan, a ko te paura maroke kaore i te ngawari ki te whakaheke i muri i te waahi mo te wa roa. He pūmau hoki i roto i te wairewa kūpapa me te kawakore, ā, karekau e hauwai ahakoa ka wera. Heoi, i roto i nga wairewa waikawa (ina koa te pH ≤ 4.0), ka ngawari te karagenan ki te hauwai waikawa, ka heke te kaha o te ra me te pokey.
1. Carrageenan hei coagulant pai, ka taea te whakakapi i te agar, te gelatin me te pectin. Ko te tiēre i mahia mai i te karagenan he rapa, ehara i te whakawehe i te wai, no reira he kaihoko reera noa mo nga tiēre.
2. Kua roa te tikanga mo te hanga kapia hua mai i te karaginana. He maamaa ake i te agar me te utu iti ake i te agar. Ko te taapiri atu ki te monamona pakeke me nga kapia ka pai te reka o te hua, he rapa, he iti ake te kirikiri, he pai ake.
3. Ahakoa karekau te karaeana e pai ana hei whakapumau tuatahi, ka taea te whakamahi hei whakapumau utu pai hei aukati i te wehenga o te whey i nga tino iti. I roto i te mahi aihikirimi me te aihikirimi, ka awhina te karagenan ki te tohatoha ngako me etahi atu waahanga totoka. He mea hanga te aihikirimi me te aihikirimi kia pai te whakarite, maeneene me te reka.
