Imbali yeezongezo zokutya E.
Igama elithi "izongezo zondlo" ngokuqhelekileyo lithetha umxube weekhemikhali ezixutywe kwaye zisetyenziselwe ukongeza okanye ukuphucula ukunambitheka kokutya okudliwe. Izongezelelo zeempilo zenziwe kwiibhubhoratri zamazwe amaninzi. Izazi-zenzululwazi zisebenzela ekudalweni kwazo.
Umsebenzi wokuqala kwakukudala nokusebenzisa izongezo zokutya ezinokuvumela ukutshintsha iipropati zokutya, oko kukuthi, ukutshintsha ubuninzi, ubuncitshisi, ukugaya okanye ukukhangela iimveliso. Kwimiqathango, ezo zongezelelo zanikezwa ileta "E", echaza iYurophu. Kukho uluvo lokuba incwadi "E" ithetha "i-batbar eDliwayo", iguqulelwe ukusuka kwisiNgesi- "idliwayo." Ukwahlula izongezelelo kwi-"E" index, udibanisa ikhodi yakho yedijithali.
Ixabiso linikezelwa ngongoma "E" kunye nekhowudi ethile emva kokukhangela ukhuseleko kunye nokugunyaziswa kokusetyenziswa kwishishini lokutya. Idijithali yedijithali iyadingeka ukuze uhlalutyo olucacileyo lwenkunkuma. Le nkqubo yeekhowudi yenziwe yiYurophu yaseYurophu kwaye yafakwa kwi-system yodidi lwamazwe ngamazwe:
E kunye nekhowudi esuka kwi-100 ukuya kuma-199 ngabadayi. Uninzi lweemveliso zongezwa ngombala usebenzisa idayi. Ngokukodwa kuxhamla iimveliso zamagqabi.
E kunye nekhowudi ukususela kwi-200 ukuya kwi-299 yi-preservatives. Izinto ezinjalo zisetyenziselwa ukwandisa ubomi besikhaliso semveliso kunye nokutshabalalisa iipilisi.
E kunye nekhowudi esuka ku-300 ukuya ku-399 yi-antioxidants (antioxidants). Ukuthintela i-oxidation ngokukhawuleza yokutya equle inani elikhulu leoli. Oku kugcina umbala wendalo wemveliso kunye nevumba layo.
E kunye nekhowudi esuka ku-400 ukuya ku-499 yilezi zizinzi (abatshayi). Izinto ezinjalo zisetyenziselwa ukwandisa i-viscosity yemveliso. Ngoku iindidi ezongezelelweyo zisetyenzisiwe kuzo zonke i-yoghurts kunye ne-mayonnaise.
E kunye nekhowudi ukususela kwi-500 ukuya ku-599-i-emulsifiers. Ezi zihlanganisi ezimangalisayo kakhulu. Ziyakwazi ukudibanisa kunye nobunzima obufanayo bokungabonakali kwemveliso, njengamanzi kunye neoli.
E kunye nekhowudi ukususela kuma-600 kuya ku-699 yilezi zongezelelo zokuphucula ukunambitheka. Ezi zinto zongeziweyo zingenza umdla ofunwayo kuyo nayiphi na imveliso. Kuthatha kuphela imicu embalwa yomkhiqizo wokuqala ukuxuba kunye nesongezelelo esisimangalisa - kunye nefuthe eliza kuvela liza kuluhlula ngoku. I-additi eqhelekileyo i-sodium glutamate, ngaphandle kwe-E-621.
E kunye nekhowudi esuka ku-900 ukuya ku-999-i-glazovateli, i-defoamers, ipowder yokubhaka, i-sweeteners- ikuvumela ukuba utshintshe ezinye zeepropati zemveliso.
Umlinganiselo wesiphumo emzimbeni womntu wezongezelo kunye nesalathisi E.
Ukusetyenziswa kweedayi kunye nokulondolozwa kwezinto kubangela ukuphendulwa komzimba kunye nokuvuvukala komzimba. Uninzi lwama-asthmatics aluchasene nokusetyenziswa kwe-antioxidant E-311, kunye nabanye abaninzi. Ngexesha elingaphambili elingalindelekanga, oku kungakhokelela ekuhlaselweni okubukhali kwesifo se-asthma.
Uninzi lwe-nitrites lubangele i-colic hepatic, ekhokelela ekukhatheni okuphezulu, kubangele utshintsho kwisimo sengqondo somntu.
Izongezo ezingena emzimbeni zibangela ukwanda okomeleleyo kwe-cholesterol, eyingozi kakhulu kubantu abadala.
Omnye ososayensi abadumileyo eUnited States - uJohn Olney wenza uchungechunge lweemvavanyo eziye zabonisa ukuba i-glutamate ye-sodium ibonakalisa ingqondo yeerati. Umntu, kunye nokusetyenziswa rhoqo kweso sihlomelo, uyeka ukuziva uveliso lwendalo lokutya.
Iingcali zenzululwazi zaseJapan ziqinisekisile nemiphumo emibi yeempembelelo zokuncedisa, ngokukodwa, kwi-retina yelihlo.
Enye yezinto eziyingozi kakhulu ngenxa yemiphumo emibi ebantwini yi-sweetener aspartame. Kwiqondo lokushisa elingaphezu kwama-30 ° C, lidilika kwi-formaldehyde enobungozi kunye ne-methanol enobuthi. Ngokusetyenziswa rhoqo kwesi sihlomelo, umntu ufumana intloko, ukuxinezeleka kwenzeka, ukuphendulwa kwemizimba, i-body idinga amanzi amaninzi.
Unokuzikhusela njani kwimiphumo eyingozi yongeziweyo?
Njengamanje, ezininzi iimveliso zokutya zisebenzisa izongezelelo zondlo. Ngoko ke, ukukhethwa kweemveliso kufuneka kuhanjiswe nazo zonke uxanduva. Ngokuqinisekileyo, ukuba abantu abahlukeneyo bancedisa ngokungafaniyo.
Umgaqo oyintloko xa ukhetha iimveliso kukuhlolwa ngokucophelela kwelebula kwiphakheji. Lo mveliso, onokwakheka kwinqanaba elincinci lee-additives E, kwaye kufuneka likhethwe. Nokuba izitolo ezibiza kakhulu azikwazi ukubonelela ukutya okukhuselekileyo kunye nokutya. Ukhuseleko luxhomekeke kuphela ekuthotyelweni komthengi.
Akunconywa ukuba adle rhoqo kwiivenkile, kwaye ngokubanzi ugweme ukutya kwi "ukutya okukhawulezayo". Yidla imifuno kunye neziqhamo ezitsha, zisela i-juice ezitsha. Kule meko, unokuphepha inani elikhulu lezifo kunye nokugula. Kwakhona, gcina iliso elifutshane malunga nokuba umntwana wakho uyondla. Gwema izithako zokutya eziyingozi ekudleni kwakhe.
