Hauv kev lag luam zaub mov, amino acids ua cov cuab yeej muaj zog rau kev txhim kho saj, kev ntxhib los mos, thiab khoom noj muaj txiaj ntsig. Piv txwv li, Glutamic acid yog dav siv los ua monosodium glutamate (MSG) los txhim kho umami tsw hauv cov kua zaub, kua ntses, thiab cov zaub mov tiav. Lub caij no, lysine thiab methionine tau nquag ntxiv los tiv thaiv cov nroj tsuag raws li cov proteins, ua kom tiav cov amino acid profile hauv cov neeg tsis noj nqaij thiab cov khoom noj vegan. Tshaj qhov tsw, cov amino acids zoo li glycine thiab proline ua raws li ntuj preservative, ncua lub neej txee thaum tswj cov zaub mov zoo. Lawv lub peev xwm los txhawb kev fermentation kuj ua rau lawv tseem ceeb hauv kev tsim cheese, yogurt, thiab dej haus fermented. Los ntawm kev sib xyaw cov amino acids rau hauv cov khoom noj khoom haus, cov tuam txhab tsim khoom tuaj yeem tsim cov khoom uas tsis tsuas yog qab tab sis kuj muaj txiaj ntsig zoo.
