Usawonongeke E202 ndi E211 - makhalidwe a ntchito

chakudya Modern n'zokayikitsa popanda zili zosiyanasiyana stabilizers, oxidizers ndi mankhwala ena. Ambiri, iwo zosiyanasiyana zina zomwe zili zofunikira kuti tipereke mtundu, kulawa kapena fungo la mankhwala, komanso kuti tidzakhale yosungirako ake. Today ife kulankhula za mchere; kutetezera kwambiri amagwiritsidwa ntchito komanso zotsatira zawo pa thupi la munthu.

ndi usawonongeke Kodi

Mchere; kutetezera monga gulu yotakata zinthu, amene anafuna kutsutsa chitukuko cha mabakiteriya. Ndi Kuwonjezera wa wothandizila ngati mankhwala chakudya n'zotheka kwambiri pa alumali moyo katundu. The mchere; kutetezera ambiri amadziwika kuti akhala akugwiritsidwa ntchito kuyambira kale kwambiri, monga uchi, shuga, mchere, vinyo, acetic ndi citric acid, ndi mowa. Iwo ankagwiritsa ntchito kale chitukuko cha mankhwala ndi chakudya mafakitale. Komabe, lero panopo akukonzekera Nkhaka kapena kumalongeza masamba ndi zipatso m'dera wakunja kwatawuni.

Mchere; kutetezera kungakhale achilengedwe kapena kupanga. Ndipo si nthawi zonse apanga mu zasayansi ya mchere; kutetezera kudzakhala zowopsa kwambiri thanzi kuposa mwachibadwa. Mu kufanizira ndi zotsatira za gulu ili la mankhwala anapatukana mu iwo kusintha malo, potero kukwaniritsa chiwonongeko cha mabakiteriya ndi zimene ziletsa ntchito yofunika kwambiri ya tizilombo zoipa.

Usawonongeke E202 - Ndi chiyani icho?

Mmodzi wa ambiri ndi E202 usawonongeke, kapena mwa njira ina - sorbate potaziyamu. Adzaupereka kwa gulu la zinthu zachilengedwe. Ikani mankhwala atetezedwe chakudya. Kunja akuimira granules sorbate kapena ufa wa mtundu woyera. Iwo kuwapeza mbewu za zipatso za zomera zina. Kuwonjezera zachilengedwe, pali apanga usawonongeke E202. Pakuti ichi asidi sorbic zopanda reagents. Chifukwa analandira calcium, potaziyamu ndi sodium, amene ntchito ya sorbates dzina lomweli.

E202 usawonongeke ali mkulu solubility (mlingo wabwino sorbates onse). Mu lita imodzi ya madzi firiji akhoza zidzasungunuka mu magalamu 138 wa thunthu. Yovomerezeka sorbate mlingo potaziyamu ndi 0.1-0.2% ya mankhwala kulemera. Gwiritsani usawonongeke izi amaloledwa pafupifupi maiko onse a dziko lapansi.

Ntchito sorbate potaziyamu

Potaziyamu sorbate ntchito pa kumalongeza zipatso ndi ndiwo zamasamba, nyama ndi nsomba. Ndiponso ntchito yokonza dzira ndi Confectionery malonda, timadziti ndi zakumwa zoziziritsa kukhosi.

E202 usawonongeke kumabwezera mmbuyo chitukuko cha nkhungu, ndipo kotero iwo anawonjezera kuti soseji ndi tchizi, rye mkate. Chifukwa chakuti mankhwala alibe kukoma, amagwiritsidwa ntchito kawirikawiri katundu chokoleti. Kuti tidzakhale ndi alumali moyo likukhudza E202 usawonongeke zipatso zouma, sauces Oriental zakudya, nyama, mayonesi, sachedwa chifukwa, vinyo ndi zina zotero. D.

Misinkhu mkulu wa acidity potaziyamu sorbate sing'anga zikusonyeza makhalidwe abwino antimicrobial. Pafupifupi nthawizonse E202 usawonongeke alipo mu mankhwala theka-yomalizidwa ndi mankhwala mazira.

Usawonongeke E202 zoipa kapena ayi?

Mpaka lero palibe kugwirizana pa nkhani imeneyi. Asayansi ambiri anavomereza harmlessness wa thunthu kwa anthu ambiri padziko lonse. Koma ofufuza ena amakhulupirira kuti sorbate potaziyamu usawonongeke, ndipo wina aliyense, silidzathyoledwa ntchito thanzi la munthu. Komanso, panali malipoti angapo aakulu, thupi lawo siligwirizana ndi thunthu.

Choncho, madokotala apanga malamulo apadera kuti kuganizira imabwera zotsatira chowawa pambuyo ntchito mankhwala ndi usawonongeke. Izi walola kuzindikira kuti mankhwala okhala zisawonongeke E-202 otetezeka kwambiri thanzi la munthu. Mwachitsanzo, mlingo zili wa sorbate mu mayonesi sayenera upambana 2 ga pa makilogalamu 1 mankhwala. Pakuti chipatso puree ndi mwana chakudya, chiwerengerochi 0,6 ga pa 1 makilogalamu.

usawonongeke E211

The chachiwiri wotchuka ntchito ndi sodium wochuluka benzoate. mankhwala angapezeke woipa otsika mu prunes, carnation, maapulo, cranberries ndi sinamoni. thunthu ndi woyera, odorless ufa ndi kutchulidwa kukoma.

thunthu ali kumafooketsa ntchito enzymatic maselo mabakiteriya, amene amachititsa kuwonongedwa kwa zokhala ndi mafuta. Komanso, sodium benzoate ali ndi mphamvu pa zina za bowa nkhungu yisiti zikhalidwe.

zoyipa

Sodium benzoate akhoza kupanga benzene. Izi zimachitika ngati thunthu amachitira ndi ascorbic asidi. Chifukwa cha mogwirizana amenewa apangidwa ndi amphamvu carcinogen zomwe zingasokoneze DNA kwa mayitirokondiriyoni, womwe zinagwira matenda aakulu.

Mu masiku sayansi m'dera mkangano mtsutso za E211 chikoka pa ana hyperactive. Polingalira za opanga lalikulu chakudya asintha zinthu kupeza m'malo njira ya thunthu.

Ena amanenera, pali chiletso pa ntchito ya E211 usawonongeke. Ku Ulaya ndi maiko CIS, izi zowonjezera chakudya amaloledwa. Komanso makampani chakudya, sodium benzoate ntchito makampani mankhwala ndi makampani ndege. Komanso, mankhwala ntchito kubala zotsatira oganiza makombola.

Mchere; kutetezera E211, E202, ndipo chiwerengero cha zinthu zina ili yofunika kwambiri masiku ano anthu ambiri. Iwo amalola kulandira ndi kunyeketsa mankhwala kuchokera kumalekezero ena a dziko. Popanda ntchito awo kuyiwala za timadziti kunja zipatso zosowa, sauces kum'maŵa ndi chokoleti Swiss.
