D(-)-Asidi wa Tartaric/ CAS：526-83-0

Kagwiritsidwe Ntchito

Chiyambi: Popeza molekyulu ya tartaric acid ili ndi ma atomu awiri ofanana a carbon asymmetric, ili ndi ma isomer atatu optical, omwe ndi dextrorotatory tartaric acid [L(+) -tartaric acid], levorotatory tartaric acid [D(-) -tartaric acid] ndi racemic tartaric acid (Meso). Kuchuluka kofanana kwa L-tartaric acid ndi D-tartaric acid kumasakanizidwa kuti apange racemic tartaric acid kapena DL-tartaric acid. L-tartaric acid ndi d-tartaric acid ndi enantiomers. Tartaric acid yonse yopezeka mwachilengedwe ndi dextrorotatory. Ndi ma crystals opanda mtundu kapena ufa woyera wosalala wa crystalline. Chopangidwa ndi crystalline chili ndi molekyulu imodzi ya madzi a crystalline, sichinunkhira, chimakhala chokhazikika mumlengalenga, chimakhala ndi kukoma kowawa, chokhala ndi malire a 0.0025%, ndipo mphamvu ya kuwawa ndi pafupifupi nthawi 1.2 mpaka 1.3 kuposa citric acid. Ili ndi kukoma kowawa pang'ono ndipo imatulutsa fungo lofanana ndi shuga wokazinga ikawotchedwa. Imakhalanso ndi zotsatira zowononga ma ayoni achitsulo. 1g imasungunuka pafupifupi mu 0.8mL ya madzi (pa 25℃), 0.5mL ya madzi otentha, ndi 3mL ya ethanol. pH ya yankho lamadzi la 0.3% ndi 2.4.

Asidi ya tartaric ndi asidi wa carboxylic womwe umapezeka m'zomera zambiri, monga mphesa ndi tamarind, komanso ndi imodzi mwa ma asidi akuluakulu achilengedwe omwe amapezeka mu vinyo. Asidi ya tartaric, monga antioxidant yomwe imawonjezeredwa ku chakudya, imatha kupatsa chakudya kukoma kowawa. Asidi ya tartaric ndi yofanana ndi citric acid ndipo ingagwiritsidwe ntchito m'makampani ogulitsa chakudya, monga popanga zakumwa. Asidi ya tartaric, ikagwiritsidwa ntchito limodzi ndi tannin, imatha kugwira ntchito ngati mordant ya utoto wa asidi. Asidi ya tartaric imatha kusakanikirana ndi ma ayoni osiyanasiyana achitsulo ndipo ingagwiritsidwe ntchito ngati chotsukira ndi choyeretsera pamwamba pa zitsulo.

Tartaric acid, yomwe imadziwikanso kuti 2, 3-dihydroxysuccinic acid, dihydroxysuccinic acid, ndi gluconic acid, ili ndi ma isomer atatu optical chifukwa cha kukhalapo kwa ma atomu awiri ofanana a carbon mu molekyulu yake. Tartaric acid imaphatikizapo D-tartaric acid, L-tartaric acid, ndi DL-tartaric acid. Tartaric acid ndi kristalo yopanda mtundu, yowonekera bwino ya prismatic kapena ufa wokhala ndi kukoma kowawa kwambiri komanso kukoma pang'ono. Imasungunuka m'madzi ndipo imapezeka kwambiri m'zomera zosiyanasiyana zachilengedwe monga mchere wa potaziyamu kapena calcium, ndipo mphesa zimakhala ndi kuchuluka kokwanira. Tartaric acid imapangidwa kuchokera ku makristasi achikasu omwe amaikidwa pansi pa migolo popanga vinyo, motero amatchedwa tartaric acid. Kuwawa kwake ndi pafupifupi nthawi 1.3 kuposa citric acid. Ntchito zake ndizofanana ndi za citric acid. Imasungunuka kwambiri m'madzi, kotero ndiyoyenera kupanga zakumwa zoziziritsa thovu. Ma crystals a tartaric acid ali ndi molekyulu imodzi ya madzi a crystalline, alibe fungo, amakhala okhazikika mumlengalenga, ali ndi kukoma kowawa, komwe kumafika pamlingo wa 0.0025%, ndipo mphamvu ya kuwawa ndi pafupifupi nthawi 1.2 mpaka 1.3 kuposa citric acid. Ali ndi kukoma kowawa pang'ono ndipo amatulutsa fungo lofanana ndi shuga wokazinga akamatenthedwa. Amakhalanso ndi zotsatira zowononga pa ayoni achitsulo. 1g imasungunuka pafupifupi mu 0.8mL ya madzi (pa 25℃), 0.5mL ya madzi otentha, ndi 3mL ya ethanol. pH ya yankho lamadzi la 0.3% ndi 2.4. Dl-tartaric acid imagwiritsidwa ntchito kwambiri ngati chowonjezera cha chakudya, mapiritsi a vitamini C effervescent, komanso chopangira mchere (choline tartrate) cha mankhwala a alkali achilengedwe, ndi zina zotero. Tartaric acid imatha kupanga mchere wa acid ndi mchere wosalowerera wokhala ndi maziko. Mwachitsanzo, ichotseni ndi potassium hydroxide kuti mupange potaziyamu hydrogen tartrate. Chomalizachi chingakonzedwenso kukhala potassium antimony tartrate (monga, * tartrate) ndi sodium potassium tartrate. Chingagwiritsidwenso ntchito popanga mchere monga sodium hydrogen tartrate, sodium tartrate ndi ammonium tartrate. Malinga ndi GB2760-86 ya dziko lathu, tartaric acid ingagwiritsidwe ntchito ngati acidulant mu zowonjezera zakudya, ndipo imagwiritsidwa ntchito mu zakumwa zoziziritsa kukhosi, jamu, zakumwa, jelly, zakudya zam'chitini ndi maswiti. Chifukwa cha hygroscopicity yake yochepa komanso kukhazikika bwino, ndi yoyenera kwambiri pa madzi a zipatso ndi zakumwa zolimba. Imagwiritsidwanso ntchito ngati emulsifier ya chakudya ndi chelating agent, komanso antioxidant enhancer. Zotsukira ndi kupukuta zitsulo pamwamba; Zipangizo zopangira mankhwala, mordants, ndi zina zotero. Nthawi zambiri imagwiritsidwa ntchito pamodzi ndi citric acid, malic acid, ndi zina zotero. Malire muzakudya zotsekemera ndi 2% (Japan) ndi 4% (United States). Chenjezo logwiritsa ntchito: Mankhwalawa ali ndi kukoma kowawa kwambiri ndipo ndi owopsa pang'ono. Nthawi zambiri amagwiritsidwa ntchito pamodzi ndi ma acid ena. Amagwiritsidwa ntchito kwambiri pokonza zakumwa ndi zakudya zina zokhala ndi kukoma kwa mphesa. Kuchuluka kwa momwe amagwiritsidwira ntchito ndi mlingo wake: Angagwiritsidwe ntchito muzakudya zosiyanasiyana pamlingo woyenera momwe amafunikira popanga. Malangizo ogwiritsira ntchito: Akagwiritsidwa ntchito pa jamu ndi ma jellies, ndibwino kusunga pH ya mankhwalawa pa 2.8 mpaka 3.5. Nthawi zambiri amagwiritsidwa ntchito limodzi ndi citric acid, malic acid, ndi zina zotero. Mankhwalawa angagwiritsidwenso ntchito pamlingo woyenera mu maswiti ndi zinthu zophikidwa, ndi zina zotero.

Kulongedza ndi Kutumiza

25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
