Kev piav qhia ntawm Citric Acid
Citric acid yog dawb, crystalline, tsis muaj zog organic acid tam sim no nyob rau hauv feem ntau cov nroj tsuag thiab ntau yam tsiaj raws li ib tug intermediate nyob rau hauv cellular ua pa.Nws zoo nkaus li tsis muaj xim, tsis muaj ntxhiab tsw muaju nrog cov kua qaub saj.Nws yog ib qho tshuaj tiv thaiv thiab kev saib xyuas thiab tseem siv los ntxiv cov kua qaub, los yog qaub, saj rau cov zaub mov thiab dej qab zib.Raws li cov khoom noj ntxiv, Citric Acid Anhydrous yog cov khoom noj khoom haus tseem ceeb hauv peb cov khoom noj.
Kev siv cov khoom
citric acid muaj astringent thiab anti-oxidant zog.Nws kuj tseem siv tau los ua cov khoom ruaj khov, pH adjuster, thiab preservative nrog lub peev xwm tsis tshua muaj zog.Nws tsis yog feem ntau khaus rau ntawm daim tawv nqaij, tab sis nws tuaj yeem ua rau kub hnyiab thiab liab thaum siv rau chapped, tawg, lossis lwm yam tawv nqaij.Nws yog muab los ntawm citrus txiv hmab txiv ntoo.
Citric Acid yog ib qho acidulant thiab antioxidant tsim los ntawm pwm fermentation ntawm qab zib tov thiab los ntawm extraction ntawm txiv qaub kua txiv, txiv qaub kua txiv, thiab pineapple canning residue.Nws yog qhov tseem ceeb tshaj plaws hauv cov txiv kab ntxwv, txiv qaub, thiab txiv qaub.Nws muaj nyob rau hauv cov ntaub ntawv anhydrous thiab monohydrate.daim ntawv anhydrous yog crystallized nyob rau hauv cov kev daws kub thiab cov monohydrate daim ntawv yog crystallized los ntawm txias (hauv qab 36.5 ° c) daws.anhydrous citric acid muaj ib tug solubility ntawm 146 g thiab monohydrate citric acid muaj ib tug solubility ntawm 175 g / 100 ml ntawm distilled dej ntawm 20 ° c.1% tov muaj ph ntawm 2.3 ntawm 25 ° C.Nws yog hygroscopic, muaj zog acid ntawm tart tsw.Nws yog siv los ua acidulant hauv cov kua txiv hmab txiv ntoo thiab cov dej haus carbonated ntawm 0.25-0.40%, cheese ntawm 3-4%, thiab hauv jellies.Nws yog siv los ua cov tshuaj tua kab mob hauv cov qos yaj ywm tam sim no, nplej chips, thiab qos yaj ywm sticks, qhov twg nws tiv thaiv kev lwj los ntawm kev ntxiab cov hlau ions.nws yog siv ua ke nrog cov tshuaj antioxidants hauv kev ua cov txiv hmab txiv ntoo tshiab khov kom tsis txhob muaj xim.
Cov txiaj ntsig ntawm citric acid
Citric acid tsis yog vitamin lossis ntxhia thiab tsis tas yuav tsum tau noj hauv kev noj haus.Txawm li cas los xij, citric acid, tsis yog yuav tsum tsis meej pem nrog ascorbic acid (vitamin C), muaj txiaj ntsig zoo rau cov neeg mob raum pob zeb.Nws inhibits pob zeb tsim thiab rhuav tshem cov pob zeb me me uas pib tsim.Citric acid tiv thaiv;citric acid ntau dua nyob rau hauv koj cov zis, qhov ntau tiv thaiv koj tiv thaiv kev tsim pob zeb tshiab rau lub raum.Citrate, siv rau hauv cov tshuaj calcium citrate thiab hauv qee cov tshuaj (xws li potassium citrate), yog ze ze rau citric acid thiab tseem muaj cov txiaj ntsig tiv thaiv pob zeb.
