Me pēhea te whānuitia i te aronga o Glutamic Acid Residue 70% i ngā tono kai ai?

Kua nui ake te uara o te tupunga hāora glutamic 70% hei āhuahanga o ngā rihii kai, nā tōna nekeneke nutrihau teitei me tōna whakawhanaketanga pai ki ētahi atu āhuahanga kai. I tokorua ahau i mahi tahi mara kai me ngā tūruhi kararehe mō tau kē, i kitea e ahau he maha ngā kaiwhakanao e heria ana ki te tino whai take mai i tēnei hua. He wā, ko te whakamahi kore pono e arataki ana ki te iti rawa o te whai take i ngā nutrihau, ā, he wā ka arataki ki ngā raru kurukuru i ngā kararehe. Ko te matua herekenga kia taea ai te whiwhi tino painga mai i te tupunga hāora glutamic ko ngā tikanga pūtaiao e ū ana ki te takotoranga tinana o ngā kararehe me ngā kaupapa herekenga kai.

Anua, me mārama ki te aha e 70% whai hua ai te tohu o te asidī glutamic. Ko te hua tēnei e kī ana i te pūtini takotoranga, ngā asidī amino, me ngā paruhi iti, ā, he tikanga nui te uaua o te pakuwe, e pai ana mō ngā kararehe rerekē, me ngā tini a te moana hoki. I taku wheako ake i te āwhina i tētahi pāmu poaka o te rahi ritenga kia pai ake tōna kai, i kitea e au ko te nuinga o ngā kaiwhilmau e wareware ana ki tana poto o ngā asidī amino. He tino nui te asidī glutamic i roto i te tohu glutamic, e hua ai te reka, ā, ka whakapai ake i te hauora o te puku o ngā kararehe. E ai ki ngā tohunga mōhio kai kararehe mai i te Rōpū Tōpahi Kai Tiriti, ka taea e te tohu o te asidī glutamic te whakakapi i tētahi wāhanga o ngā pūtini utu nui pērā i te kai ika, kaitea ai ngā utu kai engari kāore i te kino i te punaha aronga. Heoi anō, me mārama kei te kore tonu te poto o ōna asidī amino, nō reira me whakamahi atu ētahi atu hua hei āki ai te aronga.

Ko te ōweenga whakakotahi o te nohoanga o te asidī glutamic 70% e rerekē ana mō ia kararehe me ngā wāhanga kōkoringa. Mō ngā kaukau kei te wā tonu houhere, ko te tāpiri i te 8% - 12% o te nohoanga asidī glutamic ki te kai ka whakanui ake i te āhuatanga whakarere kai, ā, ka whakatakarite pūpahi. I tētahi wā i whakarititia e au he pāmu manu kia huri i tō rātou ōweenga mai i te 5% ki te 10%, ā, i roto i tētahi marama, ka piki ake te pikinga taumaha o ngā kaukau umanga 10% i te wa e iti ake ai te kai kua kaihia 7%. Mō ngā poaka u, ko te ōweenga tika ko te 6% - 9% nā te mea ka āwhina i te uwhi u me te tautoko i te hoki ake o te poaka. Ko ngā kararehe wai hoki pērā i ngā ika me ngā kōura e hua ana i te nohoanga o te asidī glutamic, me te ōweenga tāpiri tino pai o te 10% - 15% ki tō rātou kai. E pā ana ngā tohunga mai i te World Aquaculture Society mō te mea me āhua e hāngai ana ki te mōhiotia o te kararehe te ōweenga, nā te mea ko te tāpiri hoihoi ka aronga ai ki te whakapiringa o te ammonia nitrogen ki te wai, i te mate pūkio rānei o ngā kararehe wai.

Ko te waihanga o te haurua glutamic te mea pai rawa atu ka honoa ki ngā huaonga e āwhina ana i tētahi ki tētahi. He pai tana takotoranga ki ngā kai pūngao pērā i te corn me te wheat bran, pēnei anō ko ngā huaonga minerai pērā i te dicalcium phosphate me te tricalcium phosphate. Kāore i tēnei takotoranga e whakatika ana i te punaha kai engari e whakapai hoki i te whakauru kai. Hei tauira, ko te waihanga i te haurua glutamic me te kai kauwea mātātoko maisara (corn gluten meal) 60% e āniwaniwa ai te itinga o ētahi haurua amino e hiahiatia ana, ā, ka hua mai he pūtini kotahi ake. I tētahi wā, i āwhina ahau i tētahi tohunga kai kauwea kia whakarerekē i tana tauānga mā te whakakotahi i te 7% o te haurua glutamic me te 15% o te kai kauwea mātātoko maisara, ā, ka hua mai te whanaketanga pai ake i ngā poaka e tipu ana. Me whakawātea i te takotoranga ki ngā huaonga e hāpai ana i ngā here kai, pērā i ngā parareka kāore i tapiria, nā te mea ka iti ake te āhua o te whakauru kai. E whai pānga ana te Rōpū Rangahau Kai Kai ki te Tukutuku Mātauranga mō te Tukutuku mā te mahi wera i ngā huaonga e whakahē ana kia mōhiotia ngā aronga kino.

Ko te whakaritenga me te whakaputanga he wāhi matua nui ki te pupuri i te pūkai e 70% o te taupua glutamic. I te wā o te hānganga kai, me waro kia iti ake te rahi o te hua (40 - 60 mesh) kia āhua kotahi ngā wāhanga, me te māmā ai hoki mō ngā kararehe. Kua kitea e ahau ētahi take i pā ai ngā tapa nui o te taupua glutamic ki te wehenga kore ōrite o ngā punaha taunakitanga, ka riro ai ētahi kararehe kaua anō kia riro i te kai tika. Me noa i te 15 meneti te wā whakauru ki ngā taputapu hānganga kai kia pai ai te hononga ki ētahi atu hua. Mō te whakaputanga, me whakaputangia te taupua glutamic ki tētahi wāhi maroke, mātātoko hau, ā, ko te haumātauranga huakore i raro iho i te 60%. Ka taea e te parurenga te pā ki te kohukohu me te maimaie o ngā punaha taunakitanga. I te wā rā, i uru mai ngā ngaru ki tētahi toihanga kai nā te whakaputa kore tika, nā reira i mau te parurenga te taupua glutamic, ka tipu te rerehua. Ko te arataki i ngā rārangi whakaputanga mai i te Paerewa Kāwanatanga Kai mō te Motu e āwhina ana i te kounga o te hua mō te wā e ono marama.

Kia rahi ake ai te pānga o te tohu glutamic, me whai mōhiohio tonu me te tautohe i ia wā. I muri i te whakauru i te hua ki te kai, titiro ki te arataki kai, te tere tipu, me te hauora o ngā kararehe. Hei tauira, mēnā ka kitea he iti ake te hiahia kai o ngā manu, e tohu ana ko te nuinga o te tohu glutamic kei te tino nui rawa, ā, ko te heke iho i te 2% - 3% e whakatika ana i te take. I ngā puna kohukohu, he mea nui te whakamātautau i te kounga o te wai i ia wā, nā te mea e taea ana e te tohu glutamic te pā ki ngā rārangi ammonia mēnā e kore e whakamahia tika. I mahi ahau ki tētahi puna kohukohu i kitea ai he nui ake te ammonia nitrogen i ō rātou awaianamu i muri i te whakamahi i te tohu glutamic. Mā te tautohe i te ōwe, me te tāpiri i ngā tikokura hei āwhina i te paruhi, i pai ai te kounga o te wai, ā, piki ake te ű āwhina o ngā ika. E whakarārangihia ana e ngā tohunga matauranga kai mō ngā kararehe kia whakamātauria ngā taputapu o te kai i ia wā, me te tautohe i te ōwe o te tohu glutamic mā runga i ngā putanga kia pono ai te kai mō ngā kararehe i ia wā o te tipu.

Hei whakamutunga, ko te whakanui ake i te pānga o te tohu glutamic 70% i ngā tiniro o te kai ko te takotoranga o te mōhio ki ana āhuatanga, te whakarerekē i ngā ōweenga, te tiaki kia rite, te mātauranga i te tukanga me te penapena, me te arotake i ngā pānga pono. Mā te arataki i ēnei tikanga kaupapa, e taea ana e ngā kaihanga kai me ngā kainuku kia whakapai ake i te mahi tipu me te hauora kararehe, ā, ko te iti iho hoki i te utu kai me te whakapai ake i te uara o te whanaketanga katoa. He kai tiniro taimana me ngā punaha nutriene te tohu glutamic, ā, mā te whakamahi tika e bringa nui ana hua ki te ahumahi kararehe me te ahumahi taiapa.
