ukusetshenziswa kwe-calcium propionate

I-calcium propanoate noma calcium propionateunefomula Ca (C2H5COO) 2. Ngusawoti we-calcium we-propanoic acid.

Njengesengezo sokudla, kubhalwe njengenombolo E engu-282 kuCodex Alimentarius. I-calcium propionate isetshenziswa njengesinqanda esivimbeleni kwimikhiqizo enhlobonhlobo, kufaka phakathi: isinkwa, ezinye izimpahla ezibhakiwe, inyama esetshenzisiwe, isondo kanye neminye imikhiqizo yobisi. [2] Kwezolimo, kuyasetshenziswa, phakathi kwezinye izinto, ukuvimbela umkhuhlane wobisi ezinkomeni futhi njengesengezo sokuphakelayo. [3] Ama-propionate avimbela ama-microbes ekukhiqizeni amandla awadingayo, njengama-benzoate enza. Kodwa-ke, ngokungafani nama-benzoate, ama-propionate awadingi indawo ene-asidi. [4]

ICalcium propionate isetshenziswa emikhiqizweni yokubhaka njenge-mold inhibitor, imvamisa ku-0.1-0.4% [5] (noma ukudla kwezilwane kungaqukatha kuze kufike ku-1%). Ukungcoliswa kwesikhunta kubhekwa njengenkinga enkulu phakathi kwababhaki, futhi izimo ezivame ukutholakala ekubhakeni zikhona ezimeni eziseduze kakhulu zokukhula kwesikhunta. [6]

Emashumini ambalwa eminyaka edlule, uBacillus mesentericus (intambo), wayeyinkinga enkulu, [7] kepha izindlela zanamuhla zokuthuthuka ezithuthukisiwe ebhikawozi, kuhlangene nenzuzo esheshayo yomkhiqizo osuphelile, zilususile lolu hlobo lokonakala. i-propionate ne-sodium propionate ziyasebenza uma kuqhathaniswa zombili izintambo ze-B. mesentericus nesikhunta. [8]

I-Metabolism ye-propionate iqala ngokuguqulwa kwayo ibe yi-propionyl coenzyme A (propionyl-CoA), okuyisinyathelo sokuqala esivamile ku-metabolism ye-carboxylic acid. Njengoba i-propanoic acid inama-carbons amathathu, i-propionyl-CoA ayikwazi ukungena ngqo kwi-beta oxidation noma imijikelezo ye-citric acid. Kuma-vertebrate amaningi, i-propionyl-CoA i-carboxylated ibe yi-D-methylmalonyl-CoA, eyakhelwe i-L-methylmalonyl-CoA. I-enzyme encike ku-vitamin B12 ivuselela ukuhlelwa kabusha kwe-L-methylmalonyl-CoA ibe yi-succinyl-CoA, emaphakathi nomjikelezo we-citric acid futhi ingafakwa kalula lapho.

Izingane ziphonswe inselelo nge-calcium propionate noma i-placebo ngesinkwa sansuku zonke esivivinyweni se-crossover esilawulwa kabili esingaboni. Yize bekungekho mehluko ophawulekayo ngezinyathelo ezimbili, umehluko obalulekile ngokwezibalo utholakele engxenyeni yezingane ezinesimilo “esibe sibi” ngenselelo (52%), uma kuqhathaniswa nenani lokuziphatha kwalo "okuthuthuke" ngenselelo (19%). [ 9] Ngenkathi i-propanoic acid ifakwa ngqo ebuchosheni bamagundane, yakhiqiza izinguquko zokuziphatha eziguqukayo (isb. Ukungasebenzi, i-dystonia, ukukhubazeka komphakathi, ukubekezela) kanye nezinguquko zobuchopho (isb.

I-calcium propionate ingasetshenziswa njengesikhunta esithelweni. [11]

Ocwaningweni lwango-1973 olwabikwa yi-EPA, ukuphathwa okuphethwe ngamanzi okungu-180 ppm we-calcium propionate kwatholakala ukuthi kunobuthi obuncane ku-bluegill sunfish. [12]

Kuyavinjelwa [hlela]
I-calcium propanoate ivinjelwe emazweni athile afana neRussia ngenxa yokungezwani komzimba nokunye nokuqunjelwa. [Ukucaphuna] Akuvinjelwe eChina. [13]
