Kuonjezera citric acid ku zipatso zamzitini kumatha kusunga kapena kusintha kukoma kwa chipatsocho, kuonjezera acidity (kuchepetsa pH mtengo) wa zipatso zina zokhala ndi acidity yochepa pamene zimasungidwa m'zitini, kufooketsa kutentha kwa tizilombo toyambitsa matenda ndikulepheretsa kukula kwawo, ndi kuchepetsa acidity yochepa.Kukula ndi kuwonongeka kwa bakiteriya nthawi zambiri kumachitika mu zipatso zamzitini.
2. Kuonjezera citric acid ku maswiti monga wowawasa wowawasa n'kosavuta kugwirizana ndi kukoma kwa zipatso.Kugwiritsiridwa ntchito kwa citric acid mu zakudya za gel monga kupanikizana ndi odzola kumatha kuchepetsa kuvulaza kwa pectin, kotero kuti zomangira za haidrojeni pakati pa mamolekyu a pectin zikhoza kupangidwa.
3. Pokonza masamba am'chitini, masamba ena amakhala amchere, ndipo kugwiritsa ntchito citric acid monga pH regulator sikungangogwira ntchito ya zokometsera, komanso kusunga khalidwe lake.
4. Citric acid ali ndi makhalidwe a chelation ndi pH kusintha, kotero kuti akhoza kuonjezera ntchito antioxidant, ziletsa ntchito enzyme ndi kutalikitsa alumali moyo wa chakudya pokonza chakudya mwamsanga-chisanu.

Effervescence ndi njira yodziwika bwino yoperekera mankhwala pazosakaniza zapakamwa, citric acid imakhudzidwa ndi sodium carbonate kapena amadzimadzi sodium bicarbonate kupanga kuchuluka kwa CO2 (IE, effervescence) ndi sodium citrate, yomwe imalola kuti zosakaniza zomwe zimagwiritsidwa ntchito mu mankhwalawa zisungunuke mwachangu ndikuwonjezera kukoma. .Mwachitsanzo, mankhwala ofewetsa tuvi tolimba ndi analgesics ndi zotsatira solubilizing.Citric acid madzi ndi Fever odwala ndi chakumwa ozizira, ndi kukoma, kuzirala, detoxification kwenikweni.citric asidi chimagwiritsidwa ntchito zosiyanasiyana zakudya zamadzimadzi m`kamwa, etc., buffering pH 3.5 ~ 4.5, kusunga bata yogwira zosakaniza, kulimbikitsa zotsatira za zotetezera.Kuphatikizika kwa citric acid ndi kukoma kwa zipatso kumapatsa anthu kukoma komwe amakonda kubisa kukoma kowawa kwa mankhwala, makamaka mankhwala achi China.Kuwonjezera 0,02% citric acid mu zosakaniza madzi akhoza kupanga zovuta kufufuza chitsulo ndi mkuwa, kuchepetsa kuwonongeka kwa zosakaniza yogwira.Kugwiritsa ntchito 0.1% ~ 0.2% citric acid papiritsi yotafuna kumatha kusintha kakomedwe ka piritsi ndikupangitsa kuti ikhale ndi kakomedwe ka mandimu.

77-92-9 - Ntchito:

Citric Acid imakhala ndi astringent komanso anti-oxidant.Itha kugwiritsidwanso ntchito ngati chokhazikika chazinthu, chosinthira pH, komanso chosungira chomwe chili ndi mphamvu zochepa zolimbikitsa.Nthawi zambiri sichikwiyitsa khungu labwinobwino, koma imatha kuyambitsa kuyaka komanso kuyaka ikagwiritsidwa ntchito pakhungu losweka, losweka, kapena lotupa.Amachokera ku zipatso za citrus.

77-92-9 - Mbiri Yakuchitanso:

Citric Acid imakhudzidwa ndi okosijeni, zoyambira, zochepetsera ndi ma nitrate achitsulo.Zochita ndi zitsulo za nitrate zimatha kuphulika.Kutentha mpaka kuwola kumayambitsa kutulutsa utsi wa acridi ndi utsi [Lewis].

77-92-9 - Mbiri Yachitetezo:

Poizoni kudzera m'mitsempha.Ndiwowopsa pang'ono ndi subcutaneous ndi intraperitoneal njira.Kudya koopsa pang'ono.Diso loopsa komanso lopweteka kwambiri pakhungu.Kukwiyitsa organic acid, ena allergenic katundu.Mafuta oyaka.Zotheka kuphulika ndi ma nitrate achitsulo.Ikatenthedwa kuti iwonongeke, imatulutsa utsi wobiriwira komanso utsi.
