Monga chowonjezera chakudya, amalembedwa kuti E nambala 282 mu Codex Alimentarius. Calcium propionate imagwiritsidwa ntchito ngati chotetezera muzinthu zosiyanasiyana, kuphatikizapo: mkate, zinthu zina zophika, nyama yothira, whey, ndi zinthu zina zamkaka. [2] Muulimi, imagwiritsidwa ntchito, mwazinthu zina, kuteteza malungo a mkaka mu ng'ombe komanso ngati chakudya chowonjezera. [3] Mankhwalawa amalepheretsa tizilombo ting'onoting'ono kuti tisatulutse mphamvu zomwe amafunikira, monga ma benzoate. Komabe, mosiyana ndi benzoates, ma propionate safuna malo okhala ndi acidic. [4]

Calcium propionate imagwiritsidwa ntchito popanga buledi ngati choletsa nkhungu, makamaka pa 0.1-0.4% [5] (ngakhale chakudya cha ziweto chimakhala ndi 1%). Kuwonongeka kwa nkhungu kumawerengedwa kuti ndi vuto lalikulu pakati pa ophika buledi, ndipo zinthu zomwe zimapezeka mukaphika zikupezeka pafupi kwambiri kuti nkhungu zikule. [6]

Zaka makumi angapo zapitazo, Bacillus mesentericus (chingwe), linali vuto lalikulu, [7] koma machitidwe amakono oyendetsera ukhondo masiku ano, kuphatikiza zomwe zatulutsidwa mwachangu, zatsala pang'ono kuwononga izi. propionate ndi sodium propionate ndizothandiza polimbana ndi B. ndi mesentericus chingwe ndi nkhungu. [8]

Metabolism of propionate imayamba ndikutembenukira ku propionyl coenzyme A (propionyl-CoA), gawo loyambirira la metabolism ya carboxylic acid. Popeza propanoic acid ili ndi ma carboni atatu, propionyl-CoA silingalowemo kapena oxidation ya beta kapena mayendedwe a citric acid. M'magulu ambiri am'mimba, propionyl-CoA imakhala ndi carboxylated ku D-methylmalonyl-CoA, yomwe imapangidwira L-methylmalonyl-CoA. Enzyme yodalira vitamini B12 imathandizira kukonzanso kwa L-methylmalonyl-CoA kukhala succinyl-CoA, yomwe ili pakatikati pa kuzungulira kwa citric acid ndipo imatha kuphatikizidwa mosavuta kumeneko.

Ana adatsutsidwa ndi calcium propionate kapena placebo kudzera mu mkate wa tsiku ndi tsiku m'mayeso a crossover olamulidwa ndi khungu. Ngakhale panalibe kusiyana kwakukulu pamagawo awiri, kusiyana kwakukulu powerengera kunapezeka mwa kuchuluka kwa ana omwe machitidwe awo "adakulirakulira" ndi zovuta (52%), poyerekeza ndi kuchuluka kwa omwe machitidwe awo "adasintha" ndikutsutsa (19%). [ [Chithunzi patsamba 9] Mankhwala a propanoic atalowetsedwa m'mitsempha ya makoswe, idatulutsa kusintha kwamachitidwe (mwachitsanzo, kusakhazikika, dystonia, kuwonongeka kwa anthu, kupirira) ndikusintha kwaubongo (mwachitsanzo, neuroinfigueation, kutha kwa glutathione) kutsanzira pang'ono autism. [10]

Calcium propionate itha kugwiritsidwa ntchito ngati fungicide pachipatso. [11]

Pakafukufuku yemwe adachitika mu 1973 ndi EPA, kayendetsedwe ka madzi ka 180 ppm ya calcium propionate adapezeka kuti ndi owopsa pang'ono ku bluegill sunfish. [12]

Kuletsa [edit]
Calcium propanoate yaletsedwa m'maiko ena monga Russia chifukwa cha ziwengo zina ndi kuphulika. [Citation] Siziletsedwa ku China. [13]
