I-benzoate ye-sodium iyi-preservative ejwayelekile esetshenziselwa izithelo ze-pie, i- jams , iziphuzo, ama-saladi, ukubuyisela kabusha, kanye ne-sauerkraut - ukudla okunomsebenzi we-pH acidic. Imithi yokuvimbela imithi, njenge-sodium benzoate isetshenziselwa ukudla okucutshungulwa ukuvimbela ukukhula kwamabhaktheriya, imvubelo noma amanye ama-microorganisms amabi angaphazamisa ukudla kwakho.
Lapho i-benzoate ye-sodium ihlanganiswa namanzi, i-benzoic acid ikhiqizwa.
I-Benzoic acid iyindlela esebenzayo yokuvikela - ifomu elivikela ukudla. I-benzoic acid nayo itholakale ngokwemvelo kwezinye izithelo ezinjengama-cranberries, ama-plums, nama-apula.
I-United States Yokudla Nezidakamizwa Zokulawulwa Kwezidakamizwa uye wafunda kakhulu i-benzoate ye-sodium futhi ithola ukuthi iphephile uma isetshenziselwa imali etholakala ezidlweni ezivamile. Ngokusho kwe-FDA, kungathatha izikhathi ezingaba ngu-180 inani le-benzoate ye-sodium ekhona ngokudla okuvamile ngaphambi kokuba kube nezinkinga noma izikhathi ezingu-90 inani le-benzoate ye-sodium engatholakala ekudleni lapho konke ukudla okudlayo kuqukethe khona inani elikhulu kakhulu le-sodium benzoate okwamanje lisetshenziswa. Yebo, lokho kuzwakala kunzima, kodwa kusho ukuthi ukulondolozwa kuphephile. Ngokusho kweKhomishana ye-FDA Ekhethiwe ngokujwayelekile ibhekwa njengezinto eziphephile s:
Akukho bufakazi obulwazi olutholakalayo bokubonisa ukuthi i-benzoic acid kanye ne-sodium benzoate njengezithako zokudla zibeka ingozi emphakathini jikelele uma isetshenziswe emazingeni okwamanje noma angase alindeleke ngokuzayo esikhathini esizayo.
Kodwa Kuthiwani Ngezinto Eziphilayo?
Amagama angase azwakale afana, kepha i-benzene ayifani ne-sodium benzoate noma ye-benzoic acid, ngakho-ke uma udla into ene-sodium benzoate eyongezwe kuyo, awunayo i-benzene. Kubalulekile ukuqonda lokho. Kunesibopho esiphakathi kwe-benzoic acid ne-benzene esibangele ukwesaba okwesibhakabhaka ekuqaleni kwama-2000.
Emuva ngaleso sikhathi, abanye abakhiqizi abaphuzayo basebenzisa inhlanganisela ye-sodium benzoate ne-ascorbic acid (i-vitamin C) emafomeni abo. Lezi zinhlanganisela ezimbili ziphephile ngaphansi kwezimo ezivamile, kodwa ngokushisa okukhulu kokushisa, zingakwazi ukuhlanganyela ukuze zenze i-benzene. Ukuvezwa kwamanani amaningi e-benzene kuyaziwa ukudala umdlavuza.
Njengoba i-potentiel yokwenziwa kwe-benzene ikhona, i-FDA yahlola iziphuzo ezingaphezu kuka-200 emuva ngo-2005. Iningi lalingenalo i-benzene nhlobo noma lalingaphansi kwezinxenye eziyisihlanu ezigidini eziyinkulungwane, okubhekwa sengathi liphephile kubantu.
Kubalulekile ukuthi uqaphele ukuthi ukushisa ngokuvamile kuvela ekushiseni kwamalahle nokushiswa kwephethiloli, hhayi kokudla noma iziphuzo - ngisho noma i-benzoate ye-sodium ne-ascorbic acid iguqukela ku-benzene, amazinga atholakala ebhodleleni le-soda ayengaphansi kwe-soda, ngakho abathengi babengekho engozini . Kodwa-ke, abakhiqizi abaphuzayo baphendulela imikhiqizo yabo, futhi ukwakheka kwe-benzene akuyona inkinga.
Umthombo weSodium?
I-benzoate ye-sodium ingenye yezithako ezongezwayo ezingafaka isandla ekusebenzeni kwakho kwe-sodium - into okumele uyihlole uma udinga ukubukela ukudla kwakho kwe-sodium. Hlola amalebuli we-Nutrition Facts ukuze uthole ukuthi isiladi esiningi kangakanani ekukhonzeni kokudla okudlayo.
