Kapia Xanthan Utu Pai a te Kaihanga, Taumata Ahumahi CAS：11138-66-2

1）Mā te pikinga ake o te tere kutikuti, ka whakaitihia te matotoru o ngā āhuatanga rheological noa, nā te whakangaromanga o te whatunga colloidal, ka waimeha te kāpia, engari i te ngaronga o te kaha kutikuti, ka taea te whakahoki mai i te matotoru, kia pai ai te pupuhi me te tukatuka. Mā te whakamahi i tēnei āhuatanga, ka tāpirihia te kapia xanthan ki te wai e hiahia ana kia matotoru. Ehara i te mea he ngāwari noa te rere o te wai i roto i te tukanga kawe, engari ka taea hoki te whakahoki ki te matotoru e hiahiatia ana i muri i te noho marino. Nō reira, he whānuitia te whakamahinga i roto i te umanga inu.

2) He wai matotoru teitei kei roto ko te 2%~3% xanthan gum i te kukū iti, me te matotoru tae atu ki te 3~7Pa.s. Nā te matotoru teitei ka whānui ngā tono, engari i te wa ano, ka raru te tukatuka muri i te whakaputanga. Ka taea e te 0.1% NaCl me ētahi atu tote kotahi-valent me te Ca, Mg me ētahi atu tote bivalent te whakaiti paku i te matotoru o te otinga kāpia iti ki raro i te 0.3%, engari ka taea te whakanui ake i te matotoru o te otinga kāpia me te kukū teitei ake.

3）Kāore rawa he rerekētanga o te matotoru o te kapia xanthan ātete wera i roto i te whānuitanga pāmahana whānui (- 98~90 ℃). Kāore i tino rerekē te matotoru o te wairewa ahakoa i puritia ki te 130 ℃ mō te 30 meneti, kātahi ka whakamatao. I muri i ētahi huringa tio-rewa, kāore i rerekē te matotoru o te kāpia. I te aroaro o te tote, he pai te pumau o te wairewa. Mena ka tāpirihia he iti o te electrolyte, pērā i te 0.5% NaCl, i te pāmahana teitei, ka taea te whakau i te matotoru o te wairewa kāpia.

4) Kāore te matotoru o te wairewa kapia xanthan ātete waikawa me te kawakore e pā ki te pH. Kāore tēnei āhuatanga ahurei i te kitea e ētahi atu mea whakamātotoru pērā i te carboxymethyl cellulose (CMC). Mena he nui rawa te kukū o te waikawa inorganic i roto i te wairewa kāpia, ka kore e pumau te wairewa kāpia; i raro i te pāmahana teitei, ka puta te waikura o te polysaccharide e te waikawa, ka heke te matotoru o te kāpia. Mena he nui ake te ihirangi NaOH i te 12%, ka whakapūpū te kapia xanthan, ka whakapūpū rānei. Mena he nui ake te kukū o te konutai kāponāte i te 5%, ka whakapūpū hoki te kapia xanthan.

5) He kaha ahurei tō te angaanga kapia xanthan ārai-enzymatic kia kore ai e pakaruhia e ngā whākōkī nā te pānga tiaki o ngā mekameka taha.

6) Ka taea te whakaranu i te kapia xanthan hototahi ki ngā otinga whakamātotoru kai e whakamahia whānuitia ana, inā koa ki te alginate, te māngaro, te carrageenan me te carrageenan. Ka piki ake te matotoru o te otinga i te āhua o te taupatupatu. He pai te hototahitanga ki ngā otinga wai me ngā tote rerekē. Heoi, mā te nui o ngā katote konganuku valence me te pH teitei ka kore e pumau. Mā te tāpiri i te matū whakahiato ka ārai i te putanga mai o te kore hototahitanga.

7) He ngāwari te wairewa o te kapia xanthan wairewa ki te wai, ā, kāore e wairewa ki ngā whakarewa porotaka pērā i te waipiro me te ketone. I roto i te whānuitanga o te pāmahana, te pH me te kukū tote, he ngāwari te wairewa ki te wai, ā, ka taea te whakarite i tana otinga wai i te pāmahana rūma. I te wā e whakaoho ana, me whakaiti te whakaranu hau. Mena ka konatunatua te kapia xanthan ki ētahi matū maroke i mua, pērā i te tote, te huka, te MSG, me ētahi atu, kātahi ka whakamakukuhia ki te iti o te wai, ā, i te mutunga ka konatunatua ki te wai, ka pai ake te mahi a te otinga piri kua oti te whakarite. Ka taea te wairewa ki roto i te maha o ngā otinga waikawa waro, ā, he pumau tana mahi.

8) Ko te kaha kawe o te 1% otinga kapia xanthan marara he 5N/m2, he mea whakatārewatanga pai rawa atu, he mea whakaū i roto i ngā tāpiringa kai.

9) He pai te pupuri wai o te kapia xanthan i te kai, ā, he pai hoki mō te pupuri i te hou o te kai.
