2. Ho eketsa citric acid ho pompong e le moemeli o bolila ho bonolo ho lumellana le tatso ea litholoana.Tšebeliso ea citric acid ka lijo tsa gel tse kang jeme le jelly e ka fokotsa ka katleho tefiso e mpe ea pectin, e le hore maqhama a hydrogen pakeng tsa limolek'hule tsa pectin a ka kenngoa.
3. Ha u sebetsana le meroho e entsoeng ka makotikoting, meroho e meng e na le alkaline, 'me ho sebelisa citric acid e le pH regulator e ke ke ea phetha karolo ea ho noa feela, empa hape e boloka boleng ba eona.
4. Citric acid e na le litšobotsi tsa chelation le pH phetoho, e le hore e ka eketsa ts'ebetso ea antioxidant, e thibela mosebetsi oa enzyme le ho lelefatsa bophelo ba sethala sa lijo ha ho etsoa lijo tse leqhoa ka potlako.
Effervescence ke mokhoa o tummeng oa ho fana ka lithethefatsi bakeng sa metsoako ea molomo, citric acid e sebetsana le sodium carbonate kapa aqueous sodium bicarbonate ho hlahisa CO2 e ngata (IE, effervescence) le sodium citrate, e lumellang metsoako e sebetsang ea lithethefatsi ho qhibiliha ka potlako le ho ntlafatsa tatso. .Ka mohlala, li-laxative le li-analgesics li na le phello ea solubilizing.Sirapo ea Citric acid ke Bakuli ba Feberu ba nang le seno se pholileng, se nang le tatso, pholileng, phello ea detoxification.citric acid e ho pharaletseng sebelisoa ka mefuta e fapaneng phepo e noral liquids, joalo-joalo, buffering pH 3.5 ~ 4.5, ho boloka botsitso ba metsoako e sebetsang, ho matlafatsa phello ea li-preservatives.Motsoako oa citric acid le tatso ea litholoana e fa batho tatso eo ba e ratang ho pata tatso e babang ea lithethefatsi, haholo-holo meriana ea setso ea Machaena.Ho eketsa 0,02% citric acid ka metsoako ea metsi ho ka etsa motsoako oa tšepe le koporo, ho liehisa ho senyeha ha metsoako e sebetsang.Tšebeliso ea 0.1% ~ 0.2% citric acid letlapeng la ho hlafuna e ka ntlafatsa tatso ea letlapa mme ea etsa hore e be le tatso ea lemone.
Citric Acid e na le lintho tse astringent le anti-oxidant.E ka boela ea sebelisoa e le sehlahisoa sa stabilizer, pH adjuster, le preservative e nang le bokhoni bo fokolang ba ho susumetsa.Hangata ha e halefise letlalong le tloaelehileng, empa e ka baka ho chesa le ho ba khubelu ha e sebelisoa letlalong le phunyehileng, le phunyehileng, kapa le ruruha ka tsela e 'ngoe.E tsoa ho litholoana tsa citrus.
Citric Acid e sebetsana le li-oxidizing agents, li-bases, li-reasease agents le metal nitrate.Metsoalle e nang le nitrate ea tšepe e kanna ea phatloha.Ho futhumala ho isa bohōleng ba ho bola ho baka ho tsoa ha mosi oa acrid le mosi [Lewis].
Chefo ka tsela ea methapo.E na le chefo e leka-lekaneng ka litsela tse ka tlas'a letlalo le tsa intraperitoneal.Ho ja chefo e nyane.Leihlo le matla le ho teneha ha letlalo le itekanetseng.E halefisang organic acid, tse ling tsa allergenic.Mokelikeli o tukang.Ho phatloha ho ka bang teng ka tšepe ea nitrate.Ha e futhumetse ho bola, e ntsha mosi le mosi.
