Njengokongezwa kokutya, kudweliswe njenge-E inombolo 282 kwiCodex Alimentarius. I-calcium propionate isetyenziswa njengesibambiso kwizinto ezahlukeneyo, kubandakanya: isonka, ezinye izinto ezibhakiweyo, inyama eqhutyiweyo, ivili kunye nezinye iimveliso zobisi. [2] Kwezolimo, iyasetyenziswa, phakathi kwezinye izinto, ukuthintela umkhuhlane wobisi ezinkomeni nanjengesongezelelo sesondlo. [3] Iipropathi zithintela ii-microbes ekuveliseni amandla eziwadingayo, njengeebenzoates. Nangona kunjalo, ngokungafaniyo neebenzoates, iipropionate azidingi imeko ye-asidi. [4]

I-calcium propionate isetyenziswa kwimveliso yokubhaka njengesithinteli sokubumba, ngesiqhelo kwi-0.1-0.4% [5] (nangona ukutya kwezilwanyana kunokuba ne-1%). Ungcoliseko lomngundo luthathwa njengengxaki enkulu kubabhaki, kwaye iimeko zifunyanwa ekubhakeni zikwimeko ezikufutshane kakhulu zokukhula komngundo. [6]

Kumashumi ambalwa eminyaka eyadlulayo, iBacillus mesentericus (intambo), yayiyingxaki enkulu, [7] kodwa iindlela eziphuculweyo zococeko kwindawo yokubhaka, zidityaniswe nengeniso ekhawulezileyo yemveliso egqityiweyo, zilususile olu hlobo lokonakala. [Ucaphulo] ipropionate kunye nesodium propionate ziyasebenza xa kuthelekiswa zombini B. mesentericus intambo nokubumba. [8]

I-Metabolism ye-propionate iqala ngokuguqula kwayo ibe yi-propionyl coenzyme A (propionyl-CoA), inyathelo lokuqala eliqhelekileyo kwimetabolism ye-carboxylic acid. Kuba ipropanoic acid ineekhabhoni ezintathu, ipropionyl-CoA ayinakungena ngqo kwi-beta oxidation okanye imijikelezo ye-citric acid. Kwiindawo ezininzi ezinomqolo, i-propionyl-CoA yi-carboxylated kwi-D-methylmalonyl-CoA, ebhalwe kwi-L-methylmalonyl-CoA. I-enzyme exhomekeke ku-vitamin B12 ikhuthaza ukulungiswa kwakhona kwe-L-methylmalonyl-CoA ukuya kwi-succinyl-CoA, ephakathi komjikelo we-citric acid kwaye inokufakwa ngokulula apho.

Abantwana bacelwe umngeni nge-calcium propionate okanye nge-placebo ngesonka semihla ngemihla kwitrosi ye-crossover elawulwa kabini engaboniyo. Nangona kwakungekho mahluko ubalulekileyo ngamanyathelo amabini, umahluko obalulekileyo ngokweenkcukacha manani wafunyanwa kwinani labantwana abaziphethe kakubi "ngomngeni" (52%), xa kuthelekiswa nenani lokuziphatha kwabo "okuphuculweyo" kunye nomceli mngeni (19%). [ 9] Xa i-propanoic acid yayifakwa ngokuthe ngqo kwiingqondo zeempuku, yavelisa utshintsho kwindlela yokuziphatha eguqukayo (umz. I-hyperactivity, i-dystonia, ukukhubazeka ekuhlaleni, ukunyamezela) kunye notshintsho lobuchopho (umz.

Ikhalsiyam propionate inokusetyenziswa njengesixhobo sokubulala ukungunda kwiziqhamo. [11]

Kuhlolisiso olwenziwe ngo-1973 olwachazwa yi-EPA, ulawulo lwamanzi lwe-180 ppm yecalcium propionate yafunyanwa inetyhefu encinci kwi-sunfish ebluegill. [12]

Ukuvala [hlela]
I-calcium propanoate iye yavalwa kumazwe athile afana ne-Russia ngenxa ye-aleji ethile kunye nokuqunjelwa. [13]
