1.Kev piav qhia ntawm anhydrous citric acid
Anhydrous citric acid nyob rau hauv chav tsev kub yog dawb crystalline hmoov, tsw thiab acidic heev nyob rau hauv cov xim, nrog ib tug ceev ntawm 1.542 g / cm3, ib tug melting point ntawm 153-159 degrees thiab decomposition kub siab tshaj 175 degrees nrog tso dej. thiab carbon. dioxide Citric acid yog yooj yim soluble nyob rau hauv dej. Lub solubility yog 59 feem pua ntawm 20 degrees, thiab pH ntawm nws 2- feem pua aqueous tov yog 2.1. Lub crystalline daim ntawv ntawm citric acid txawv nyob ntawm seb lub crystallization tej yam kev mob. Nws erodes me ntsis nyob rau hauv qhuav huab cua thiab yog hygroscopic nyob rau hauv cov huab cua ntub. Nws tuaj yeem decompose rau hauv ntau yam khoom thaum rhuab thiab reacts nrog acids, alkalis, glycerin, thiab lwm yam. Thaum citric acid yaj nyob rau hauv ethanol, nws reacts nrog ethanol los ua ethyl citrate.

3. Daim ntawv thov ntawm anhydrous citric acid
Anhydrous citric acid yog ib hom txiv hmab txiv ntoo acid, tseem hu ua citric acid, uas tuaj yeem ua kom daim tawv nqaij rov ua dua tshiab. Nws cov yam ntxwv acidic tuaj yeem siv los ua tus neeg sawv cev flavoring, cov khoom siv tshuaj txhua hnub, preservatives, thiab lwm yam. Nws lub luag haujlwm tseem ceeb yog raws li hauv qab no:
Khoom noj khoom haus Additive: Cov zaub mov qib citric acid yog cov organic acid uas muaj zog qaub saj, siab citrus txiv hmab txiv ntoo, pineapple, txiv qaub thiab lwm yam txiv hmab txiv ntoo, thiab saj zoo. Nws tuaj yeem muab ntxiv rau cov dej qab zib thiab zaub mov hauv qhov tsim nyog, uas tuaj yeem txhim kho qab los noj mov thiab saj;
Cov Khoom Siv Tshuaj Txhua Hnub: Khoom noj khoom haus qib citric acid tuaj yeem ua kom lub cev metabolism sai, txhawb cov tawv nqaij rov ua dua tshiab, thiab tuaj yeem siv rau hauv cov khoom siv tshuaj txhua hnub los pab ua kom tawv nqaij thiab ua kom tawv nqaij ci dua;
Preservatives: Edible citric acid yog ib qho acidic acid heev. Cov kua qaub ib puag ncig tsim los ntawm citric acid tuaj yeem tiv thaiv kev loj hlob ntawm cov kab mob kom tsis txhob muaj cov khoom noj khoom haus thiab ua kom muaj kev tiv thaiv corrosion.
Citric acid tseem tuaj yeem cuam tshuam cov calcium hauv cov ntshav, ua kom cov hlab ntsha mos thiab tiv thaiv atherosclerosis. Tsis muaj kev phom sij rau kev noj cov citric acid hauv qhov tsim nyog, tab sis kev noj cov zaub mov mus sij hawm ntev, jam thiab lwm yam zaub mov ua tiav yuav yooj yim ua rau ntau dhau ntawm citric acid hauv lub cev, yog li ua kom cov calcium tawm hauv lub cev, thiab yooj yim ua hypocalcemia.
