Umbuzo: Ngiyawuthanda lawo ma-patties ama-veggie e-frogs engiwathenga esitolo, kodwa ngelinye ilanga owesifazane wangitshela ukuthi bathole i-hexane kubo. I-Hexane ibuhlungu; kwenzenjani? Ingabe ama-burgers we-veggie aqukethe i-hexane futhi lokhu kusho ukuthi angifanele ngiwadle?
Impendulo: I- Veggie burgers ayinakho i-hexane. Empeleni, zingasetshenziswa njengomthombo wamaprotheni onempilo kubantu abadla imifino.
Indlela I-Hexane Eyisebenzisa Ngayo Embonini Yokudla
I-United States Food and Drug Administration (FDA) ayidingi ukudla okumele kuhlolwe amazinga we-hexane - mhlawumbe ngenxa yokuthi amathuba okuthola ukuvezwa okunenjongo ekudleni akunakwenzeka. Ukhululekile kakhulu ukuthi utholakale ku-hexane ngokusebenzisa i-essol fumes, iglue-drying glue, kanye nokuhlanza ama-solvents kunanoma yikuphi ukudla okudlayo.
I-Hexane iyinhlanganisela eyenziwe ngamafutha angcolile. Embonini yokudla, i-hexane isetshenziselwa ukukhipha amafutha emifino ezinhlameni zezitshalo ezifana ne- canola , ama-soybean, i-sunflowers, kanye nommbila ngoba kusebenza kahle futhi kungabizi kakhulu kunokukhipha amafutha ngama-presses. I-hexane isusiwe emafutheni ngaphambi kokuba ibhaliswe futhi ithengiswe, kodwa kukhona njalo okunye okungase kube khona okunye okusele kwe-hexane okumele kushiywe emafutheni.
I-FDA ayizange imise umkhawulo wezinsalela ze-hexane ekudleni. Kodwa-ke, usethe imingcele yamazinga okuhlala emahlathini futhi udla amaprotheni okudla.
Njengoba akuyona into yokudla ngokuvamile evivinywa, kunzima ukwazi ukuthi ingakanani i-hexane engase ibe khona kunoma yikuphi ukudla okuthengayo. Ayaziwa ukuthi ingakanani i-hexane yokudla ingase ibangele inkinga nakuba ucwaningo lwamanje lubonisa ukuthi kuzothatha ubukhulu be-hexane ngaphezu kwalokho okutholakala ekudleni.
I-Cornucopia Institute, inhlangano eyakhelwe ukusekela ezolimo eziphilayo nezilimi ezincane, yathi ukudla okunama-soy efana ne-veggie-burgers kanye nemigoqo ethile yokudla okungase ingcoliswe ne-hexane. Bafaka iziphetho zabo kancane kancane esifundweni esincane eSwitzerland esibheka (phakathi kwezinye izinto) amazinga we-hexane emafutheni okupheka eSwitzerland.
Awekho amafutha aqukethwe okungaphezu kuka-0.13 milligrams kilogram yamafutha kanye namaphesenti angu-88 ayengaqukathi lutho lwe-hexane nhlobo. Lesi sikhungo godu sathumela isampula esisodwa sokudla nesoso ku-FDA ukuze sihlolwe. Ama-sampuli aqukethe izinsalela ze-hexane (izingxenye ezingu-21 nezingu-14 ngezigidi ngasinye), ezifana nemingcele ebekwe ama-hops okukhishwa yi-FDA. Njengoba imikhiqizo eminingi yemifino kanye nemishayo yokudla isebenzisa amaprotheni e-soy njengesithako, ukwesaba ukuthi izinhlangano ezingekho ezingokwemvelo noma eziyingxenye yezinto zokudla zingase zingcolile nge-hexane.
I-Hexane Toxicity
I-Hexane inobuthi, futhi ukuvezwa kwemali enkulu kungabangela umonakalo wezinzwa. Kodwa akuveli ekudleni. Ukuvezwa kwe-Hexane kungenzeka kwenzeke kubantu abasebenza ezindaweni zokucwenga amafutha nezinye izindawo lapho i-hexane ingabalekela khona emoyeni. Ucwaningo lwamanje lwezokwelapha lugxila ekuvezweni kwezezimboni kanye nezindiza ezingenayo i-hexane, ngakho-ke akucaci ukuthi ukuchayeka okuningi kwe-hexane ekudleni kungaba yingozi.
I-EPA inqume ukuthi ukudla okungaphansi kuka-0.06 milligrams hexane kilogram yesisindo somzimba cishe kuphephile. Umuntu ongamakhilogremu angu-200 (97.7 kilogremu), lokho kungaba ngama-milligram ama-5.8 ngosuku. Ukudla okwejwayelekile, ngisho nokunye okunamafutha omquba we-hexane, okwakungeke kube khona kakhulu. Ngokwesibonelo, amafutha esifundweni saseSwitzerland ne-hexane kakhulu aqukethe i-0.13-milligram hexane ngayinye kilogram yamafutha, ngakho-ke umuntu oyedwa wamaphilisi angama-200 kufanele adle amamitha angu-40 alawo mafutha aze afinyelele ku-5.8 milligrams hexane.
Ingabe kunzima ukugwema i-hexane? Iningi le-hexane livezwa emoyeni, kodwa-ke, uma ufisa ukuqeda ama-resix e-hexane ekudleni kwakho, ungakhetha ukudla "okungamaphesenti angama-100 e-organic" kanye namafutha ashicilelwa ngaphandle kwe-solvent-ekhishwe.
Ukucindezela ukuthutha akusebenzi ngendlela efana ne-hexane extraction ngakho amafutha enza ngale ndlela azoba abizayo kakhulu. Khumbula ukuthi amalebuli athi umkhiqizo wenziwe ngezithako eziphilayo kungenzeka usasebenzisa izithako eziye zavezwa ku-hexane.
