ʻAkika D(-)-Tartaric/ CAS：526-83-0

Hoʻohana

Hoʻolauna: No ka mea, aia i loko o ka molekole waikawa tartaric ʻelua mau ʻātoma kalapona asymmetric like, he ʻekolu ona isomers optical, ʻo ia hoʻi ka waikawa tartaric dextrorotatory [L(+) -tartaric acid], ka waikawa tartaric levorotatory [D(-) -tartaric acid] a me ka waikawa tartaric racemic (Meso). Hoʻohui like ʻia ka nui o ka waikawa L-tartaric a me ka waikawa D-tartaric e loaʻa ai ka waikawa tartaric racemic a i ʻole ka waikawa DL-tartaric. ʻO ka waikawa L-tartaric a me ka waikawa d-tartaric he enantiomers. ʻO nā waikawa tartaric kūlohelohe a pau he dextrorotatory. He mau kristal moakaka kala ʻole ia a i ʻole ka pauka crystalline keʻokeʻo maikaʻi a granular. Loaʻa i ka huahana crystalline hoʻokahi molekole o ka wai crystalline, ʻaʻohe ʻala, paʻa i ka lewa, he ʻono ʻawaʻawa, me ka paepae ʻawaʻawa o 0.0025%, a ʻo ka ikaika o ka ʻawaʻawa ma kahi o 1.2 a 1.3 mau manawa o ka waikawa citric. He ʻono astringent iki kona a hāʻawi i kahi pilau e like me ke kō i kālua ʻia i ka wā e puhi ʻia ai. Loaʻa iā ia nā hopena chelating ma nā ion metala. Hoʻoheheʻe ʻia ʻo 1g ma kahi o 0.8mL o ka wai (ma 25 ℃), 0.5mL o ka wai e paila ana, a me 3mL o ka ethanol. ʻO ka pH o kahi hopena wai 0.3% he 2.4.

ʻO ka waikawa tartaric kahi waikawa carboxylic i loaʻa i nā mea kanu he nui, e like me nā hua waina a me ka tamarind, a ʻo ia kekahi o nā waikawa organik nui i ka waina. ʻO ka waikawa Tartaric, ma ke ʻano he antioxidant i hoʻohui ʻia i ka meaʻai, hiki ke hāʻawi i ka meaʻai i kahi ʻono ʻawaʻawa. Ua like ka waikawa Tartaric me ka waikawa citric a hiki ke hoʻohana ʻia i ka ʻoihana meaʻai, e like me ka hana ʻana i nā mea inu. ʻO ka waikawa Tartaric, i ka wā e hoʻohana ʻia ai me ka tannin, hiki ke lawelawe ma ke ʻano he mordant no nā dyes waikawa. Hiki i ka waikawa Tartaric ke hui pū me nā ion metala like ʻole a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe a me ka mea hoʻopili no nā ʻili metala.

ʻO ka waikawa Tartaric, i ʻike ʻia hoʻi ʻo 2, 3-dihydroxysuccinic acid, dihydroxysuccinic acid, a me ka gluconic acid, he ʻekolu mau isomers optical ma muli o ke alo o ʻelua mau ʻātoma kalapona asymmetric like i loko o kāna molekala. Loaʻa i ka waikawa Tartaric ka waikawa D-tartaric, ka waikawa L-tartaric, a me ka waikawa DL-tartaric. ʻO ka waikawa Tartaric kahi kristal prismatic moakaka ʻole, ʻaʻohe kala a i ʻole ka pauka me kahi ʻono ʻawaʻawa ikaika a me kahi ʻono iki. Hiki ke hoʻoheheʻe ʻia i ka wai a loaʻa nui ʻia i nā mea kanu like ʻole ma ke ʻano ma ke ʻano o ka paʻakai potassium a i ʻole calcium, me nā hua waina he nui ka nui. Hana ʻia ka waikawa Tartaric mai nā kristal melemele i waiho ʻia ma lalo o nā pahu i ka wā o ka hana waina, no laila ka inoa tartaric acid. ʻO kona ʻawaʻawa ma kahi o 1.3 mau manawa o ka waikawa citric. Ua like kona hoʻohana ʻana me nā waikawa citric. He mea hoʻoheheʻe loa ia i ka wai, no laila kūpono ia no ka hana ʻana i nā mea inu huʻa. Loaʻa i nā kristal waikawa Tartaric hoʻokahi molekala o ka wai crystalline, ʻaʻohe ʻala, paʻa i ka lewa, he ʻono ʻawaʻawa, me ka paepae ʻawaʻawa o 0.0025%, a ʻo ka ikaika o ka ʻawaʻawa ma kahi o 1.2 a 1.3 mau manawa o ka waikawa citric. He ʻono astringent iki ko lākou a hāʻawi i kahi pilau e like me ke kō i kālua ʻia i ka wā e puhi ʻia ai. Loaʻa iā lākou nā hopena chelating ma nā ion metala. Hoʻoheheʻe ʻia ka 1g ma kahi o 0.8mL o ka wai (ma 25 ℃), 0.5mL o ka wai e paila ana, a me 3mL o ka ethanol. ʻO ka pH o kahi hopena wai 0.3% he 2.4. Hoʻohana nui ʻia ka waikawa Dl-tartaric ma ke ʻano he mea hoʻohui meaʻai, nā papa effervescent vitamin C, a me kahi mea hoʻohui acidifying paʻakai (choline tartrate) no nā lāʻau alkali organik, a pēlā aku. Hiki i ka waikawa Tartaric ke hana i nā paʻakai waikawa a me nā paʻakai kūlike me nā kumu. No ka laʻana, e hoʻopau iā ia me ka potassium hydroxide e hana i ka potassium hydrogen tartrate. Hiki ke hoʻololi hou ʻia ka mea hope i loko o ka potassium antimony tartrate (ʻo ia hoʻi, * tartrate) a me ka sodium potassium tartrate. Hiki ke hoʻohana ʻia e hana i nā paʻakai e like me ka sodium hydrogen tartrate, sodium tartrate a me ka ammonium tartrate. Wahi a GB2760-86 o ko mākou ʻāina, hiki ke hoʻohana ʻia ka waikawa tartaric ma ke ʻano he acidulant i nā mea hoʻohui meaʻai, a hoʻohana ʻia i loko o nā mea inu anu, nā jam, nā mea inu, ka jelly, nā meaʻai i loko o ka pahu a me nā candies. Ma muli o kona hygroscopicity haʻahaʻa a me ke kūpaʻa maikaʻi, kūpono loa ia no ka wai huaʻai a me nā mea inu paʻa. Hoʻohana ʻia hoʻi ia ma ke ʻano he emulsifier meaʻai a me ka chelating agent, a me ka mea hoʻonui antioxidant. Nā mea hoʻomaʻemaʻe ʻili metala a me nā polish; Nā mea maka lāʻau lapaʻau, nā mordants, a pēlā aku. Hoʻohana pinepine ʻia ia me ka citric acid, malic acid, a pēlā aku. ʻO ka palena i nā meaʻai ʻono he 2% (Iapana) a me 4% (ʻAmelika Hui Pū ʻIa). Nā akahele no ka hoʻohana ʻana: He ʻono ʻawaʻawa ikaika kēia huahana a he astringent iki. Hoʻohana pinepine ʻia ia me nā waikawa ʻē aʻe. Hoʻohana nui ʻia ia no ka hoʻomākaukau ʻana i nā mea inu a me nā meaʻai ʻē aʻe me ka ʻono hua waina. Ka laulā o ka hoʻohana a me ka nui: Hiki ke hoʻohana ʻia i nā meaʻai like ʻole i nā nui kūpono e like me ka mea e pono ai no ka hana ʻana. Kuhikuhi hoʻohana pono: Ke hoʻohana ʻia no nā jams a me nā jellies, he mea kūpono ke mālama i ka pH o ka huahana ma 2.8 a 3.5. Hoʻohana pinepine ʻia me ka citric acid, malic acid, a pēlā aku. Hiki ke hoʻohana ʻia kēia huahana i nā nui kūpono i nā candies a me nā mea i hoʻomoʻa ʻia, a pēlā aku.

ʻŌpala a me ka Hoʻouna ʻana

25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa

Mālama a me ka mālama ʻana

Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
