Propionic asidhi E280

Propionic asidhi ndizvo zvokudya chirungiso, zvisaora. Anotsvaka sezvinoita mvura jikichira rakachenuruka yellowish kana vasina kudaro mukuru.

Propionic asidhi ane yakashapa kunaka uye kunzwa kunhuwa. The kwemakemikari yokuita nefuma - S2N5SOON.

Kugadzirira propionic asidhi

E280 fuma zvakasikwa iri mafuta uye sezvo Kubudirira mune fermentative nomumwe zvinomera. Panguva chinovira pamusoro makabhohaidhiretsi chiri kuumbwa propionic acid. Kuwana nzira utachiona ndiyo metabolic manyowa pane mafuta acids ane kabhoni maatomu nenzira zvinoshamisa nhamba, uye kuwedzera munhu amino acids.

Utachiona kubva genus Propioni utachiona zvibereko zvinhu sezvo kuguma yemudzimu anaerobic muviri. Sezvo utachiona izvi kazhinji aripo mudumbu ruminants, dzimwe mhando chizi vane chaiyo munhuhwi.

Industrially, propionic asidhi achiumbwa munyika carbonylation pamusoro ethylene Reppe kuita, ari CATALYTIC oxidation ose (pamberi manganese ions kana cobalt) propionaldehyde. Uyezve, imwe pfuma yakabereka kuva byproduct mu nedanho gasi danho oxidation pamusoro C4 -C10 Mahydrocarbon.

Yakapfuura propionic asidhi oga kuva byproduct panguva kugadzirwa kwezvinhu acetic acid. Zvisinei, unyanzvi hwokugadzira zvinhu mazuvano ari zvaAtemisi yokupedzisira akasunda nzira yekare nevamwe zvisaora kupinda necheseri.

Propionic asidhi anobvumirwa kushandisa muchimiro zvisaora ari mari magiramu anosvika matatu chete churu chizi (fused) zvigadzirwa uyewo zvigadzirwa kubva kwavari, pamwe chete sorbic acid, ayo munyu kana nomumwe. Zvinogonekawo kushandisa zvisaora gorosi (mumapepa sliced), rye nokuti kwenguva refu kuchengetwa, uye zvokudya pasi simba ukoshi. Propionic asidhi anobvumirwa kushandisa chikanywa zvigadzirwa, mukanyiwa-kubika chingwa.

By zvichivhiringidza (deceleration) zvimwe makemikari zvisaora anokwanisa kupa non-chaiwo inhibitory zvainoita hunhu marudzi akawanda utachiona, chakuvhuvhu uye mbiriso, dzimwe mhando anogona kudzidza kuvenga kana kubereka nayo.

Kuderedza uwandu propionic asidhi kushandiswa zvisingaiti. Izvi imhaka yokuti pane wevasungwa pakati 0.3% zvisaora yekudyidzana alters kunaka uye hwema chigadzirwa. Panyaya iyi, yaigadzira zvokudya propionic asidhi rinoshandiswa muchimiro karusiyamu propionate uye yavaibvisa kushanda chete panguva ndichengetedze bhekari zvigadzirwa.

Zvisaora E280 anokwanisa zvichivhiringidza (kunonoka) kukura tusingaoneki serum uye mukaka. Panyaya iyi, propionic asidhi inoshandiswa canning whey aine maonero kuti chekuchengeta neyokufambisa. Uyezve, fuma iri rinoshandiswa kudzivirira zviyo zvakanyanyisa nyoro muforoma (kana kwete dryers zvakakwana simba).

Kushandisa propionic asidhi iwayo akakurumbira dzimwe sectors. Saka, zvisaora zvaishandiswa pakugadzira Pharmaceuticals (Fenobolina, ibuprofen nevamwe), zvinonhuwirira zvinhu (geranyl propionate, phenylpropionate , uye vamwe) uye mapurasitiki (polivinilpropionata) vinilplastifikatorov, solvent (propyl propionate, propyl propionate nevamwe).

Chikuru ngozi izvo zvingave E280 - zvemakemikari anopisa zvichida kuitika kana pakubata pfungwa yokushanda acid. A nhamba yezvidzidzo zvakawana kuti zvisaora-chepfu, carcinogenic, uye zvinogona kukanganisa kuti nhengo dzokubereka nadzo.

Mumuviri, pane nokukurumidza oxidation propionic iine acid excretion riri muchimiro carbon dioxide inobvisa iri riri Krebs kutenderera.
