ʻO ka sodium citrate, he ʻeleʻele kala ʻole a i ʻole keʻokeʻo crystalline pauka huahana; ʻAʻohe ona ʻala, ʻono paʻakai, a maʻalili. E nalowale ana kona wai aniani ma 150 °C a e decomposed ma kahi kiʻekiʻe o ka wela. He liʻiliʻi ka deliquescence i loko o ka ea pulu a loaʻa ka waiwai ma luna o ka ea wela. Hiki ke hoʻoheheʻe ʻia i ka wai a me ka glycerol, akā ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waiʻona a me kekahi mau mea hoʻoheheʻe organik. ʻAʻohe hopena ʻona o ka sodium citrate, a loaʻa iā ia ka hiki ke hoʻoponopono i ka pH a me ka paʻa maikaʻi, a no laila hiki ke hoʻohana ʻia i ka ʻoihana meaʻai.
Hana a me ka noi
ʻO ka sodium citrate ka makemake nui loa i ka wā e hoʻohana ʻia ai i mea hoʻohui meaʻai; Ma keʻano he meaʻai meaʻai, hoʻohana nuiʻia e like me nā meaʻono, buffers, emulsifiers, bulking agents, stabilizers a me preservatives; Eia kekahi, hiki ke hoʻohana ʻia ka hui pū ʻana ma waena o ka sodium citrate a me ka waikawa citric i nā ʻano jams, jelly, wai, nā mea inu, nā mea inu anu, nā huahana dairy a me nā pastries gelling agents, flavoring agents and nutritional supplements. hoʻohana ʻia no ka hana ʻana i nā lāʻau anti-clotting; a hoʻohana ʻia e like me nā mea hoʻohui detergent i ka ʻoihana māmā.
Hana maikaʻi loa
1.Safe a nontoxic waiwai; No ka mea ʻo ka mea kumu kumu no ka hoʻomākaukau ʻana i ka sodium citrate ka mea nui mai ka meaʻai, palekana loa a hilinaʻi ʻole me ka ʻole e hōʻeha i ke olakino kanaka. ʻAʻohe palena o ka United Nations Food and Agriculture a me ka World Health Organization i kāna ʻai ʻana i kēlā me kēia lā, ʻo ia ka mea hiki ke noʻonoʻo ʻia kēia huahana he meaʻai ʻole.
2. He mea biodegradable. Ma hope o ka hoʻoheheʻe ʻia ʻana o ka nui o ka wai, ua hoʻololi ʻia ka sodium citrate i citrate, e noho pū ana me ka sodium citrate i ka ʻōnaehana like. He maʻalahi ka citrate i ka hoʻohaʻahaʻa ʻana i ka wai ma ka hana o ka oxygen, ka wela, ka māmā, ka bacteria a me nā microbes. Ke hele nei kona mau ala decomposition ma o ka aconitic acid, itaconic acid, citraconic acid anhydride e hoʻololi hou ʻia i carbon dioxide a me ka wai.
3. ʻO ka hiki ke hana paʻakikī me nā ion metala. Hiki i ka sodium citrate ke hana paʻakikī me kekahi mau ion metala e like me Ca2+, Mg2+; no nā ion ʻē aʻe e like me Fe2+, loaʻa iā ia kahi mana paʻakikī maikaʻi.
4.Excellent solubility, a hoʻonui ka solubility me ka piʻi ʻana o ka mahana o ka wai.
5. He mana maikaʻi kona no ka hoʻoponopono pH a me kahi waiwai buffering maikaʻi. ʻO ka sodium citrate kahi paʻakai alkali ikaika-ʻakika; Ke hui pū ʻia me ka citrate, hiki iā lākou ke hana i kahi pale pH me ka hoʻohālikelike ikaika; no laila, he mea maikaʻi loa kēia no kekahi mau hihia i kūpono ʻole ka hoʻololi nui ʻana o ka waiwai pH. Eia kekahi, ʻoi aku ka maikaʻi o ka sodium citrate i ka hana retardation a me ka paʻa.
