E202 ndi mchere wa potaziyamu wa asidi acid. Izi zimapezeka m'madzi a phiri ash, ndipo poyamba zidali zosiyana ndi August Hoffmann mu 1859, dzina lake linaperekedwa pofuna kulemekeza dzina lachilatini la Rowan - Sorbus. Choyamba kupanga sorbic acid chinapangidwira mu 1900 ndi Oscar Döbner. Ma salt a asidiwa amapezeka chifukwa chogwirizana ndi alkali. Mafakitale omwe amatengedwa amatchedwa otbates. Ziphuphu za potaziyamu, calcium ndi sodium, komanso asidi palokha, zimagwiritsidwa ntchito ngati zosungira zakudya zamakono, zodzoladzola komanso zamagetsi, chifukwa izi zimatha kuletsa kukula kwa nkhungu ndi yisiti bowa, komanso mabakiteriya ena.
Kodi e202 ili kuti?
Ichi ndi chodziwika bwino chotetezera. Amagwiritsidwa ntchito pokonzekera zakudya monga:
- mayonesi ndi mayonesi sauces;
- tchizi;
- sausages ndi nyama mankhwala osachepera ;
- masamba ndi zipatso zimasunga;
- timadziti;
- fillers kwa yogurt;
- mikate ndi zakudya;
- osamwa mowa;
- vinyo.
Komanso, phula la potassium imagwiritsidwa ntchito mu zodzoladzola zakonzekera shampoos, lotions, creams. Kawirikawiri, mphukira ya potassium imagwiritsidwa ntchito pamodzi ndi zina zoteteza, kotero kuti kutali kwambiri ndi zinthu zopanda phindu zingathe kuwonjezeredwa kuzinthu zochepa.
Kodi E202 ndi yovulaza kapena ayi?
Monga choonjezera cha chakudya E202 chomwe chinagwiritsidwa ntchito kuyambira pakati pa zaka zapitazo, komabe palibe chidziwitso chodziwitsa za zotsatira zake zovulaza thupi la munthu. Pa nthawi yonse yogwiritsira ntchito E202, mawonetseredwe okha a zovulazidwa zomwe zimayambitsidwa ndi izi zowonjezera, zomwe nthawi zina zimagwiritsidwa ntchito.
Komabe, pali lingaliro lakuti kugwiritsa ntchito zotetezera zilizonse zingakhale zoopsa.
Malingaliro awa, kuchuluka kwa mphulukiti wa potassium mu zakudya zogulira sizingowonjezereka ndi ziwerengero zamakalata ndi mayiko apadziko lonse. Kawirikawiri, chakudya chake sichiyenera kupitirira 0,2 g mpaka 1.5 g pa kilogalamu yamaliza.
