Kazhinji munharaunda ye "chimiro", ine zvokudya zvakawanda, tinogona kuona nhamba duku yekudzidzisa Е202. Kune vanhu vasina ruzivo ruzivo, pamwe chete nevaya vasina hanya nezvezvokudya, tichazarura "chakavanzika" cheE202 - inonzi sorbate ye potassium. Inowanikwa nekuita kwe potassium hydroxide uye sorbic acid. Kwenguva yekutanga, iyi asidi, pamwe nemamwe emashizha ayo (masbate) akawanikwa muna 1859 kubva mujusi reSoubus aucuparia gomo remhepo, (saka zita rechikamu chacho). Muna 1939 yakawanikwa kuti makemikari akawanikwa ane antimicrobial uye antifungal properties. Kubva kuma1950, shybic acid uye masbate e sodium uye potassium ave achishandiswa mumakambani ezvokudya semagadzirirwo - makemikari asingabvumi mabhakitiriya akasiyana siyana uye fungi kuti awedzere mune zvigadzirwa, izvo zvinowedzera mararamiro emararamiro ekupedzisira.
Properties uye kushandiswa kweE202
Tsvina yePotassium ikristini shoma shoma ine mushure mushure mekurwadza, isina kunaka. Iyo nyore nyore kusungunuka mumvura, pasina ethanol. Preservative E202 inowanzoshandiswa mumushandi. Inoshandiswa:
- nokuda kwekugadzirwa kwezvigadzirwa zvesausage;
- apo kuchengetedza miriwo uye michina yekugadzirwa kwavo (tomato purees, pastas, caviar kubva mumiriwo);
- vari mukugadzira michero uye berry jams, jams, kubika stuffs;
- mukugadzirwa kwemichero yakaoma , kuchengetedza e202 inoshandiswa zvakare;
- nokuda kwekuita cheeses, bhotela uye kupararira;
- kuitira kuti awedzere mararamiro echefeteri ekunyanya kubheka;
- nokuda kwekugadzirwa kwewaini zhinji (kunyanya waini yakaoma);
- nokuda kwekugadzirwa kwezvinwiwa zvinotapira;
- muzvipfeko.
Inowanzoshandiswawo musanganiswa nemamwe magadziro ekuderedza huwandu hwavo (E202-sodium benzoate, somuenzaniso), sezvo E202 inofanana neanogue yakachengeteka. Tsvina yePotassium inobvumirwa munyika dzakawanda dzepasi - USA, Canada, nyika dzeEuropean Union, Russia.
Icho chiri kuchengetedza E202 chinokuvadza here?
Pasinei nehafu yezana remakore yekushandiswa, kuchengetedza E202, panguva ino, hapana chakaipa chezvinhu izvi pamuviri womunhu. Kunze kwechokwadi hakusi nyore kugadziriswa kweaorigic. Kunyange zvazvo mamwe masayendisiti ari kuda kusvika pakupedzisira kuti kushandiswa kwekuchengetedza chero kupi zvingakanganisa muviri wedu, nokuti kunogona kuvhiringidza basa rake pamagetsi. Uye kunyange zvazvo sorbate ye potassium haina kana yakagadziriswa yekuti incogenic kana mutagenic yega kuitira kuti irege kukuvadza zvinogona kuitika, muyero wekuchengetedza E202 muzvokudya unonyatsorongedzwa nezvibvumirano zvenyika dzakawanda. Pakati pevhesi, zvinyorwa zve potassium sorbate zvinotorwa kuva 0.02-0.2% yehuremu hwechigadzirwa chakapedzwa.
