Huahana Huahana
L(+)-Tartaric acid he kala kala ʻole a translucent, a i ʻole he keʻokeʻo, granular maikaʻi, pauka crystalline. ʻAʻohe ona ʻala, ʻono ʻakika, a paʻa i ka ea.
L(+)-Tartaric acid ua hoʻohana nui ʻia ma ke ʻano he acidulant i ka inu a me nā meaʻai ʻē aʻe. Me kāna hana optical, hoʻohana ʻia ka L (+) -Tartaric acid ma ke ʻano he mea hoʻonā kemika e hoʻonā i ka DL-amino-butanol, kahi mea waena no ka lāʻau antitubercular. A hoʻohana ʻia ia e like me ka wai chiral e synthesize i nā derivatives tartrate. Me kona ʻakika, hoʻohana ʻia ia ma ke ʻano he catalyst i ka hoʻopau resin o ka lole polyester a i ʻole ka pH waiwai regulator i ka hana oryzanol. Me kona paʻakikī, hoʻohana ʻia ka L (+) -Tartaric acid i ka electroplating, ka wehe ʻana i ka sulfur, a me ka pickling acid. Hoʻohana ʻia ʻo ia ma ke ʻano he mea paʻakikī, mea hoʻohui meaʻai screening agent a i ʻole chelating agent i ka loiloi kemika a me ka nānā ʻana i ka lāʻau lapaʻau, a i ʻole he mea kūʻē i ke kala. Me kona hōʻemi ʻana, hoʻohana ʻia ia ma ke ʻano he mea hoʻohaʻahaʻa i ka hana ʻana i ke aniani chemically a i ʻole imaging agent i ke kiʻi. Hiki ke paʻakikī pū me ka ion metala a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaʻemaʻe a i ʻole polishing agent o ka ʻili metala.

ʻOihana Meaʻai
- E like me ka acidifier a me ka mālama kūlohelohe no nā marmalades, ice cream, jellies, wai, mālama, a me nā mea inu.
- E like me ka effervescent no ka wai kalapona.
- E like me ka emulsifier a me ka preservative i ka ʻoihana hana berena a i ka hoʻomākaukau ʻana i nā candies a me nā mea ʻono.
Oenology: Hoʻohana ʻia e like me ka acidifier. Hoʻohana ʻia i nā pono a me nā waina e hoʻomākaukau ai i nā waina i ʻoi aku ke kaulike mai ka manaʻo o ka ʻono, ʻo ka hopena ka hoʻonui ʻana i ko lākou pae o ka acidity a me ka emi ʻana o kā lākou pH maʻi.
ʻOihana Hoʻomaʻamaʻa: Hoʻohana ʻia ma ke ʻano he kumu kumu o nā crèmes kino maoli.
