BetaineHe momo tāpiri kore-kai te matū nei. He matū hangai, he matū tango rānei i ahu mai i ngā matū kei roto i ngā kararehe me ngā tipu tino pai o ngā kararehe wai. He maha ngā momo matū e rua e titoa ana hei kukume kai. He pānga tahi ēnei matū ki te whāngai i ngā kararehe wai. Mā te whakaoho i te kakara, te reka me te tirohanga a ngā kararehe wai, ka taea e rātou te huihui ki te taha o te whāngai, te whakateretere i te whāngai, me te whakanui ake i te kai e kainga ana.

I whakapotoa te wā whāngai o te Macrobrachium rosenbergii mā te 1/3~1/2, ā, i whakanuia te nui o te whāngai mā te tāpiribetaineki te whāngai i te kōura. Ko te kai kei rotobetaineHe mārama te pānga kukume kai ki te kāpa me te kāpa paru, engari kāore he pānga kukume kai mārama ki te kāpa tarutaru. Ka taea hoki e te Betaine te whakarei ake i te reka o ētahi atu waikawa amino ki ngā ika, me te whakarei ake i te kukume kai a ngā waikawa amino. Ko ngā mahi a te mōunu Betaine he whakapai ake i te hiahia kai, te whakapakari i te ātete ki te mate me te ārai mate. Ka ātete te pāpaka mate ki te mōunu rongoā, ā, ka whakaea te kai iti o te ika me te pāpaka i raro i te ahotea.

He matūkai nui te Choline i roto i ngā kararehe. Ka taea e ia te whakarato i te methyl mō te tinana i roto i te tinana ora, nō reira ka whai wāhi ki ngā tauhohenga pākia. I ngā tau tata nei, kua kitea e ngā rangahau ka taea hoki e te betaine te whakarato i te methyl mō te tinana. Ko te whai huatanga o te betaine ki te whakarato i te methyl he 2.3 ngā wā i te choline chloride, ā, he kaituku methyl whai hua ake. I te whakamahinga o te betaine hei whakakapi i te choline chloride i roto i te whāngai, ka piki ake te roa tinana toharite o Macrobrachium rosenbergii mā te 27.63%, ā, ka heke te tauwehenga whāngai mā te 8% i muri i ngā rā 150 ki te whakataurite ki te rōpū whakahaere.BetaineKa taea te whakapai ake i te tukanga waikura o ngā waikawa ngako i roto i ngā mitochondria pūtau, ka whakanui ake i te ihirangi o te acyl carnitine mekameka roa me te ōwehenga o te acyl carnitine mekameka roa ki te carnitine kore utu i roto i te uaua me te ate, ka whakatairanga i te pirau ngako, ka whakaiti i te whakatakotoranga ngako i roto i te ate me te tinana, ka whakatairanga i te hanganga pūmua, ka tohatoha anō i te ngako tinana, ka whakaiti i te tere o te mate ate ngako.
