Betainendi mtundu wa chowonjezera chopanda zakudya. Ndi chinthu chopangidwa mwaluso kapena chochotsedwa pogwiritsa ntchito mankhwala omwe ali m'zinyama ndi zomera zomwe nyama za m'madzi zimakonda kwambiri. Zinthu zokopa chakudya nthawi zambiri zimakhala ndi mitundu yoposa iwiri ya mankhwala. Mankhwalawa ali ndi mphamvu yogwirizana pa kudyetsa nyama za m'madzi. Mwa kupangitsa fungo, kukoma ndi masomphenya a nyama za m'madzi, amatha kusonkhana mozungulira chakudya, kufulumizitsa kudyetsa, ndikuwonjezera kudya.

Nthawi yodyetsera ya Macrobrachium rosenbergii inafupikitsidwa ndi 1/3 ~ 1/2 ndipo kuchuluka kwa chakudya kunawonjezeka powonjezerabetainechakudya cha nkhanu. Zakudya zomwe zili ndibetaineBetaine imathanso kukulitsa kukoma kwa ma amino acid ena ku nsomba ndikuwonjezera kukongola kwa ma amino acid. Betaine chambo ili ndi ntchito yowonjezera chilakolako cha chakudya, kukulitsa kukana matenda komanso chitetezo chamthupi. Nkhanu za matenda zimalimbana ndi chambo cha mankhwala ndipo zimathandiza kuchepetsa kudya kwa nsomba ndi nkhanu zomwe zili ndi nkhawa.

Choline ndi michere yofunika kwambiri m'zinyama. Imatha kupereka methyl m'thupi m'thupi, motero imagwira ntchito mu kagayidwe kachakudya. M'zaka zaposachedwa, kafukufuku wapeza kuti betaine ingaperekenso methyl m'thupi. Kugwira ntchito bwino kwa betaine popereka methyl ndi kuwirikiza kawiri ndi choline chloride, ndipo ndi wopereka methyl wothandiza kwambiri. Pamene betaine idagwiritsidwa ntchito m'malo mwa choline chloride m'zakudya, kutalika kwa thupi la Macrobrachium rosenbergii kunakwera ndi 27.63% ndipo kuchuluka kwa chakudya kunachepa ndi 8% patatha masiku 150 poyerekeza ndi gulu lolamulira.BetaineKungathandize kusintha njira yowola mafuta acids mu mitochondria ya maselo, kuonjezera kwambiri kuchuluka kwa acyl carnitine ya unyolo wautali ndi chiŵerengero cha acyl carnitine ya unyolo wautali ku carnitine yaulere mu minofu ndi chiwindi, kulimbikitsa kuwola kwa mafuta, kuchepetsa kuyika kwa mafuta m'chiwindi ndi m'thupi, kulimbikitsa kupanga mapuloteni, kugawanso mafuta a nyama, ndikuchepetsa kuchuluka kwa mafuta m'chiwindi.
