Nyob rau hauv chav tsev kub, citric acid 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, 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.

Ib qho ntawm feem ntau sivTxiv qaub acidraws li ib tug khoom noj additive raws li ib tug preservative. Nws tau ntxiv rau ntau cov zaub mov hauv kaus poom, cov khoom ci thiab cov khoom noj siv mis kom ua rau lawv lub neej txee thiab tiv thaiv kev lwj. Nws muaj cov khoom siv tshuaj tua kab mob uas pab tiv thaiv kev loj hlob ntawm cov kab mob, pwm thiab lwm yam kab mob tsis zoo uas tuaj yeem ua rau muaj kab mob hauv cov zaub mov. Tsis tas li ntawd, nws kuj ua haujlwm raws li tus neeg sawv cev chelate, uas txhais tau hais tias nws tuaj yeem khi rau cov hlau ions thiab tiv thaiv lawv los ntawm kev cuam tshuam nrog lwm cov khoom xyaw hauv cov zaub mov, uas tuaj yeem ua rau lwj.

Qhov nokuj plays lub luag haujlwm tseem ceeb hauv kev lag luam ci. Nws feem ntau ntxiv rau cov khoom ci xws li ncuav mog qab zib, muffins thiab ncuav qab zib los tsim cov khoom sib tw ntau dua thiab sib dua. Nws yog vimTxiv qaub acidreacts nrog baking soda los tsim carbon dioxide, ua rau lub khob noom cookie sawv hauv qhov cub. Tsis tas li ntawd, nws tuaj yeem ua tau raws li qhov ua kom muaj txiaj ntsig hauv cov khoom ci, vim nws tuaj yeem pab coj tawm qhov tsw ntawm lwm cov khoom xyaw hauv daim ntawv qhia.
