Iyo Hexane Inoshandiswa Sei muShizha Rokudya
IUnited States Food uye Drug Administration (FDA) haifaniri kudya kuti iongorwe mazinga ehexane - zvichida nokuti mikana iyo iwe uchaona kusunungurwa kunobatsira kubva pakudya haigoni kuitika.

Iyo hexane inobviswa pamafuta isati yavharwa uye inotengeswa, asi pane nguva dzose iyo inogona kuti imwe nzvimbo ye hexane isarwe mumafuta.
I-FDA haina kuisa muganhu wezvinyorwa zve hexane muzvokudya. Kunyange zvakadaro, yakagadzirisa miganhu yezvikamu zvakasara muhombodo nehove yeprotekta.
Sezvo zvisiri chimwe chinhu chikafu chinowanzoedzwa, zvakaoma kuziva kuti inguva yakawanda hexane inogona kunge iri mune zvokudya zvaunotenga. Hazvizivikanwi kuti zvikafu zvakawanda zvinokonzera hexane zvinogona kukonzera dambudziko kunyange zvazvo kutsvakurudza kwezvino kuchiratidza kuti zvinotora kukura kwehexane kune izvo zvingawanika mukudya.
Chikamu chinonzi Cornucopia Institute, sangano rakagadzirwa kuti ribatsire hurima hwekurima nekurima-purazi, rakati zvokudya zve soya zvakadai sa veggie-burgers uye zvimwe zvirongwa zvekudya zvinogona kusvibiswa ne hexane. Vakagadzirisa zvikamu zvavo pane zvidzidzo zvishoma muSwitzerland izvo zvakatarisa (pakati pezvimwe zvinhu) hexane mazinga muSwitzerland kubika mafuta.
Hapana yeairi yaiva nemadhora 0,1 milligiramu pa kilogram yemafuta uye 88 muzana yakanga isina mitoo ye hexane zvachose. Nzvimbo iyi yakatumirawo imwe samuro yezvokudya zve soya uye gits kune FDA yekuenzanisa. Iyo samples yaiva nemasara e hexane (21 ne14 zvikamu pamamiriyoni), ayo akafanana nemiganhu yakagadzirirwa hops zvinyorwa neDFA. Sezvo michero yakawanda yemichero uye miviri yezvokudya inoshandisa mapuroteni e-soy senhengo, sangano rinotya kuti zvisiri zvisikwa kana zvishoma zvezvinhu zvakasikwa zvekudya izvi zvinogona kusvibiswa ne hexane.
Hexane Toxicity
Hexane inotyisa, uye kuonekwa kune zvakawanda zvinogona kukonzera kukanganisa kwemhepo. Asi hazvibvi pakudya.

Ikozvino kutsvaga kutsvakurudza kunotarisa pamabhizimisi uye mumhepo inotarisana ne hexane, saka hazvisi pachena kuti hexane yakawanda kubva mune zvekudya ingave yakaipa.
EPA inofungidzira kuti kudya kudarika ma 0,06 milligrams hexane kilogram yehutatu hwehuviri zvichida yakachengeteka. Kune munhu-pound 200 (97.7 kilograms), iyo inenge iri mamiriyoni 5,8 pazuva. Chimwe chikafu chekudya, kunyange imwe ine mafuta akawanda ehexane-yakabudiswa yemafuta, ingadai ichingopera. Semuenzaniso, mafuta muSwitzerland achidzidza nehexane yakange ine 0.13-milligram hexane kilogram yemafuta, saka 200-pound munhu aifanira kudarika makumi mana emakironi emafuta iwayo kuti asvike pedyo ne 5.8 milligrams hexane.
Zvakaoma here kurega hexane? Mazhinji hexane exposure inouya nemhepo, zvakadaro, kana iwe uchida kubvisa mararamiro ehexane kubva pane kudya kwako, unogona kusarudza kudya "100-percent organic" nemafuta anotengesa-panzvimbo pane kugadziriswa-yakabviswa.
Expeller pressing haisi inobudirira sezvinoita hexane extraction kuitira kuti mafuta akaitwa nenzira iyi achange ari anodhura. Ramba uchiyeuka kuti mavara anotaura kuti chigadzirwa chacho chinogadzirwa nemafuta ezvokudya angave achishandisa zvishandiso zvakave zvakarongedzwa ne hexane.
