Propionic acid E280

Propionic acid waa daro cuntada, preservative ah. Waxa muuqata in guud dareere ah sida ka muuqanaysa hurdi ama aan lahayn saliid.

Propionic acid leedahay dhadhan dhanaan iyo urta pungent. formula The kiimiko oo ah walaxda - S2N5SOON.

Diyaarinta Propionic acid

walax E280 ee dabiiciga ah ee ku jira oo saliid ah iyo sida a-saarka by in dhirta shaqsi fermentative. Inta lagu guda jiro halsano of carbohydrates waxaa sidoo kale la aasaasay Propionic acid. Helitaanka habka nafleyda waa kala daatay ee dheefshiidka ee acids dufanka leh kuwaas oo ka kooban atamka carbon in tiro kisi ah, iyo ballaarinta acids amino shaqsi.

Bakteeriyada ka Propioni wax soo saarka bakteeriyada panulirus sida wax soo saarka dhamaadka shiid anaerobic ah. Tan iyo bakteeriyada, kuwaas oo inta badan ay joogaan ee caloosha ariga, noocyo ka mid ah farmaajo leeyihiin caraf gaar ah.

Industrially, Propionic acid laga sameeyey carbonylation ee ethylene Reppe reaction, qayilo ka horseed ah (in joogitaanka udhigo manganese ama Cobalt) propionaldehyde. Intaas waxaa sii dheer, walaxda la soo saaray sida byproduct ah ee geedi socodka of qayilo wajiga gaaska ee Consort C4 -C10.

Markii hore Propionic acid waxaa go'doonsan sida byproduct ah inta lagu guda jiro soo saarka ee acetic acid. Si kastaba ha ahaatee, farsamada casriga ah ee soo saaridda ee dambe ku riixay habka jir ah oo la takooro preservative ah oo wuxuu galay taariikhda.

Propionic acid waa la ogol yahay in la isticmaalo qaab oo ah ilaaliye ah in lacagta ah oo ilaa saddex grams halkii xabbadood ee kilo (dhisnayd) waxyaabaha iyo sidoo kale waxyaabaha iyaga ka dhigay, si wadajir ah ula acid sorbic, cusbada ama shaqsi ahaan. Waxa kale oo suuragal ah la isticmaalo oo ah ilaaliye ah sarreen (baakadeeyey jarjaran), galley kaydinta daba dheeraaday, iyo kibis kula qiimaha tamarta yar. Propionic acid waa la ogol yahay in la isticmaalo in wax soo saarka cajiin, cajiinka-soda.

By anada (deceleration) of falgalka qaarkood preservative waa awoodaan in ay bixiyaan saamayn inhibitory non-gaar ah oo ku saabsan nooca noocyo badan oo ka mid ah bakteeriyada, caaryada iyo khamiirka, noocyada qaar ka mid ah uu u nuugo kartaa ama u soo saaraan.

Xadaynta xaddiga of Propionic acid loo isticmaalo waa shaqayn karto. Tan waxa u sabab xaqiiqada ah in at uruuray of 0.3% preservative si weyn wixiii dhadhanka iyo urta ee alaabta. Marka tan la eego, in warshadaha cuntada Propionic acid waxaa loo isticmaalaa foomka of propionate calcium iyo sodium ficil ahaan oo kaliya inta lagu guda jiro kaydinta alaabta la xasho.

Qurmidda E280 awood u anada (gaabis) koritaanka sheyga serum iyo caano. Marka tan la eego, Propionic acid waxaa loo isticmaalaa in Canning myse gol leeyahay in lagu keydiyo iyo gaadiidka. Waxaa intaa dheer, walax this waxaa loo isticmaalaa inay hadhuudh ka soo caaryada xad-dhaafka ah oo qoyan ilaaliyo (haddii aan la geynin ku filan oo awood badan).

Codsiga of Propionic acid waa wax caadi ah in qaybaha kale. Sidaas daraaddeed, preservative loo isticmaalo wax soo saarka ee dawooyinka (Fenobolina, ibuprofen iyo kuwa kale), walxaha leedahay beduliyum (propionate geranyl, phenylpropionate , iyo kuwa kale) iyo bacyaal (polivinilpropionata) vinilplastifikatorov, dareeraha (propionate propyl, propionate propyl iyo kuwo kale).

Khatarta ugu weyn waxaa laga yaabaa in E280 - kiimiko ka gubtay badan tahay in ay dhacdaa marka la xoog acid wax ka qabashada. Tiro diraasado ah ayaa lagu ogaaday in ay xubnaha taranka preservative-sun ah, cudurka kansarka, iyo si xun u saameyn karaa.

In jidhka, waxaa jira a qayilo degdeg Digo Propionic acid waa qaab dioxide kaarboon in wareegga Krebs ah.
