DL-Alanine (H-DL-Ala-OH; DL-Ala) (CAS: 302-72-7) Ntchito:
1. Mankhwala
(1) DL-Alanine ndi zofunika zopangira kwa kaphatikizidwe VB6, zakudya ndi chimodzi mwa zigawo za kudzaza koyera amino zidulo zakudya kulowetsedwa.
(2) DL-Alanine monga chigawo chachikulu cha jekeseni wa amino acid - 800, kupezeka kwa chiwindi, ubongo, ndi kuthandiza odwala kwa chiwindi chikomokere mwamsanga, ndi mtundu wa mankhwala diuresis.
(3) DL-alanine ndi yofunika wapakatikati kwa synthesis ena mankhwala ndi mankhwala, tizilombo zachipatala ndi zamankhwala amuzolengedwa amino asidi kagayidwe mankhwala.
2. Zakudya zowonjezera
(1) DL-Alanine akhoza kusintha zakudya mtengo wa chakudya, mu mitundu yonse ya zakudya ndi zakumwa, monga: mkate, madzi ayezi mfundo, zipatso tiyi, mkaka, koloko, sorbet, ndi zina zotero.Add 0.1 ~ 1% ya alanine mwachionekere kusintha mlingo magwiritsidwe ntchito ya mapuloteni chakudya ndi chakumwa, ndi chifukwa alanine ali makhalidwe a akhoza odzipereka ndi maselo mwachindunji, Choncho, pambuyo kumwa akhoza mwamsanga kubwezeretsa kutopa, mpumulo.
(2) Zotsekemera zopangira zokometsera kuti zimveke bwino, zingapangitse kutsekemera, kuchepetsa mlingo. Pamodzi ndi sweet mei wothandizira wa 1 ~ 10% wa alanine, amatha kusintha kutsekemera, okoma, ofewa ngati mei wotsekemera wachilengedwe, ndipo akhoza kusintha kukoma.
(3) DL-Alanine ili ndi kutsekemera kwapadera, Imagwiritsidwa ntchito kwambiri ngati zowonjezera zowonjezera komanso zokometsera m'makampani opanga zakudya.Ntchito ngati flavoring agent.Ikhoza kuwonjezera zonunkhira zokometsera zotsatira;Kuwongolera kungagwiritsidwenso ntchito ngati wowawasa wothandizira, kusintha kukoma kowawa kwa organic acid.
(4) Ndi kukoma wowawasa, kupanga mchere kulawa mofulumira, kusintha zotsatira za pickles, pickles, akhoza kufupikitsa pickling nthawi, kusintha kukoma;Monga chothandizira kuwongolera asidi komanso chosungira chifukwa chopangira komanso zakumwa zotsitsimula, zitha kuletsa kukalamba kwa vinyo wonyezimira ndikuchepetsa fungo la yisiti.Angagwiritsidwe ntchito mitundu yonse ya processing chakudya, monga mafuta, mayonesi, coarse chakudya, soya msuzi impregnation chakudya, mpunga chinangwa kuzifutsa chakudya, etc. Sizingateteze makutidwe ndi okosijeni, komanso kusintha kukoma kwake.
(5) DL-alanine imagwiritsidwa ntchito ngati zakudya zowonjezera komanso zokometsera.Ikhoza kusintha kukoma kokometsetsa, kuonjezera wowawasa wa organic acid.Ndipo DL-alanine itha kugwiritsidwa ntchito mu pickles, zakumwa ndi vinyo.
