Ina hiahia koe ki te whakatakoto i tētahi kai reka, i tētahi kapia, i tētahi hua miraka rānei, e rua ngā ingoa e tino puta ake ana:te gelatin e taea te kaimeagar agarHe rite tonu te hanga o ngā mea e rua ki ngā kirikiri, engari he rerekē rawa ngā kai — ā, ko te kōwhiringa "tika" kei runga i tō hua, i tō tukanga, me ō kaihoko. I ētahi wā ka whakaaro ngā kaihanga he "paura kirikiri" ēnei, ā, ka kitea ko te whakawhiti i tētahi ki tētahi ka huri i te kakano, te whanonga rewa, tae atu ki te ora tonu o te hua i te tukunga. Mā tēnei whakatairite ka whakamāramahia te rerekētanga o ēnei mea kia taea ai e koe te whiriwhiri me te māia, me te karo i te hanga anō utu nui i muri mai.

He aha te Agar Agar?

Ko te agar agar (he maha ngā wā ko te "agar") hehydrocolloid tipu-hangai tangohia mai i te rimu whero (Rhodophyta). Ko te polysaccharide hanganga i roto i te pakitara pūtau o te rimurimu, i whakangawaritia hei paura, hei maramara, hei pae rānei. Nā te mea i ahu mai i te rimu, ka hangaia te agar-agar i roto i te āhua tūturuhe kaiwhenua, he kaiwhenua, ā, he halal/kosher te tikanga taunoa — he painga nui mō ngā raina hua tipu.

I roto i te āhua matū, he matatini te agar-agar o te agarose me te agar-pectin. Ka noho hei kirikiri pakari, pakarukaru i ngā kukū iti rawa (te nuinga o te 0.5–1.0%), ā, ko te mea nui,ka rewa i te 80–90 °C — he nui ake i te pāmahana o te tinana. Koia te take e mau tonu ai te āhua o ngā hua kua whakatakotoria ki te agar i te pāmahana rūma, ā, kāore e "rewa i roto i te waha"(Pang me ētahi atu, 2020).

Ka hokona te agar arumoni hei paura, hei kirikiri, hei pae rānei, ā, me kohuatia (95–100 °C) kia memeha rawa i mua i te whakamatao — he rerekē ki te gelatin, e whakamakuku ana, e memeha ana ki te wai mahana. Nā te mea he rerekē ngā kotinga rimu i runga i te wā me te rohe, ka nui ake te rerekētanga o te utu me te tuku agar i ngā awa hua kararehe o te gelatin, he mea nui tēnei mō ngā kaihoko nui.

He aha te Gelatin e taea te kai? (Whakarāpopototanga Tere)

Te gelatin e taea te kaihepūmuai ahu mai i te waikura wāhanga o te collagen kararehe (ngā hiako kau, ngā hiako poaka, ngā wheua rānei). Ka hangaiangā tiēre whakahurihuri-wera e rewa ana i te pāmahana tata ki te tinana (~35 °C), e hoatu ana ki ngā kai he kakano maeneene, "rewa-i-te-waha" e hono ana ki ngā kapia kounga teitei, ngā māshmallow, me te panna cotta. Ko te tikanga ka whakatakotoria ki te 2–10% te kukū i runga i te kaha o te pua.(TIPU, nd).

E rua ngā momo matua o te gelatin:Momo A(kua tukatukahia ki te waikawa) me te pūwāhi isoelectric teitei ake (~7–9), meMomo B(kua tukatukahia ki te kawakawa) me te ira isoelectric iti iho (~4.7–5.4). Ka pā taua rerekētanga ki te taunekeneke a te gelatin ki te pH o tō hanganga — he mea nui ina honoa ki ngā pūnaha hua waikawa, ki ngā miraka rānei. Ko te kaha o te gel (80–320) ka whakahaere i te pakari o te gel. Mō te ruku hohonu ake, tirohia tā mātou aratohu mōte māramatangatiērekaha.

Whakataurite taha-ki-taha

Rerekētanga matua:Ka rewa te tiakarete i te pāmahana tinana, ā, ka puta he ngau pīwariwari, ka rewa ki roto i te waha. He pumau te agar ki te wera, ā, ka puta he pūmau, he pakarukaru. Kāore e taea te whakawhiti i te karamu mō te karamu — mā te whakawhiti i tētahi mō tētahi ka huri i tō tunu kai me tō wheako kaihoko.

Te Utu, te Wātea me te Pūtake

I runga i te tikanga mō ia kirokaramu, ko te agar te tikangautu nui akei te gelatin, engari ko tōna taumata whakamahinga iti rawa (tata ki te kotahi-rima ki te kotahi-tekau o te horopeta) ka taea te whakawhāiti i te āputa i roto i te hua kua oti. Ka whai hua te gelatin mai i te tuku pumau e herea ana ki ngā awa hua taha o te umanga mīti, ko te tuku agar e whai ana i ngā kotinga rimu, ā, ka taea te whakawhāiti i ngā wā rawakore, i ngā here kaweake rānei. Mō ngā kaihoko o te ao, ka tukuna hoki e te gelatin he ara tiwhikete ngāwari ake - tae atu ki te kore poakate gelatin kau, te gelatin ika, meNgā taumata HALAL/Kosher — engari ko te takenga mai o te agar ka tutuki aunoa i te nuinga o ngā kereme whakapono me ngā kereme vegan. Ina rongoatia, he paura maroke pumau ēnei e rua, engari he tairongo ake te gelatin ki te haumākū nui (ka taea te piri me te whakapūpū), nō reira he nui ake te hiranga o te rokiroki e whakahaerehia ana te āhuarangi mō te gelatin i te agar.

Tohutoro Tere o te Taupānga

Ngā Pātai Auau: Me Whakakapi noa e Au tētahi mō tētahi atu?

Kāore i te tika. Nā te mea ka hanga te agar-agar i te hauwhā o te horopeta, ā, kāore e rewa i roto i te waha, mā te whakakapi i te gelatin 1:1 ka puta he hua pakari, pakarukaru; mā te whakakapi i te agar-agar ki te gelatin ka waiho he hua āhua-pōturi, ka memeha. Ki te mea me huri koe (hei tauira, ki te hanga i tētahi putanga vegan o tētahi tunu gelatin), whakatauritea te taumata whakamahinga, whakarerekētia te pāmahana tautuhinga me te rokiroki, me te whakamātautau anō i te kakano me te roa o te oranga. Me whakaaro he whakahou anō, ehara i te whakakapinga.
