Qhov sib txawv tseem ceeb ntawm cov roj hydrogenated thiab cov roj hydrogenated ib nrab yog cov roj hydrogenated yog cov roj uas muaj tag nrho cov C=C bonds txo, whereas ib nrab hydrogenated roj yog cov roj uas muaj qee qhov C=C bonds hloov thiab qee C=C bonds unchanged.
Cov ntsiab lus hydrogenated thiab qee cov roj hydrogenated poob rau hauv cov ntsiab lus ntawm cov roj hydrogenation. Fat hydrogenation yog cov txheej txheem ntawm kev sib txuas cov rog xws li zaub roj nrog hydrogen, uas ua rau nws ntau saturated. Feem ntau, cov txheej txheem no yog ua nyob rau hauv high-pressure tej yam kev mob thiab yuav tsum tau ib tug nickel catalyst. Hydrogenation txo tag nrho cov carbon-carbon ob daim ntawv cog lus. Tab sis yog tias cov tshuaj tiv thaiv yog ib feem, nws yuav txo tau qee qhov carbon-carbon ob daim ntawv cog lus thaum lwm cov paib carbon-carbon tseem tsis hloov pauv.
Hydrogenated Roj yog dab tsi?
Hydrogenated roj yog roj uas muaj tag nrho cov C=C bonds txo. Hydrogenated roj yog ib hom roj uas siv los ntawm qee lub tuam txhab khoom noj kom khaws cov zaub mov tshiab rau lub sijhawm ntev. Cov txheej txheem no suav nrog qhov sib ntxiv ntawm hydrogen rau cov kua roj xws li roj zaub. Nws hloov cov roj rau hauv cov rog rog ntawm chav tsev kub. Peb muaj peev xwm categorize hydrogenated roj raws li ib nrab hydrogenated roj thiab tag nrho hydrogenated roj. Txawm li cas los xij, lo lus hydrogenated roj feem ntau yog hais txog cov roj hydrogenated tag nrho.
Hauv cov roj hydrogenated tag nrho, cov roj ua kua tau hloov mus rau hauv cov khoom ntawm chav tsev kub. Hauv hom roj no, yuav luag tag nrho cov C=C daim ntawv cog lus raug txo vim qhov sib ntxiv ntawm hydrogen. Nws txo cov rog rog hauv cov khoom kawg. Cov roj uas muaj hydrogenated tseem siv tau zoo sib xws rau cov roj hydrogenated ib nrab.
Cov roj hydrogenated tuaj yeem siv tau zoo. Txawm li cas los xij, tsis tau txhais hais tias cov roj no yuav tsum zoo rau peb txoj kev noj qab haus huv. Qhov no yog vim cov khoom noj uas muaj cov roj hydrogenated feem ntau ua tiav nrog cov suab thaj thiab ntsev ntxiv.
Dab tsi yog Hydrogenated Oil?
Ib nrab cov roj hydrogenated yog ib hom roj hydrogenated uas qee qhov C=C daim ntawv cog lus raug txo thaum lwm C=C daim ntawv cog lus tseem tsis hloov. Yav dhau los, cov tuam ntxhab siv cov roj no thaum tsim khoom noj, tab sis tam sim no tsis siv raws li FDA cov cai. Hom roj no hu ua trans fat. Cov khoom noj uas muaj cov roj ntau ntau suav nrog cov khoom ci, cov nplaum nplaum, cov nplaum nplaum, kas fes creamers, thiab khoom noj txom ncauj.
Feem ntau, cov roj hydrogenated ib nrab lossis cov roj trans tsis muaj kev nyab xeeb hauv cov khoom noj. Yog li ntawd, cov tuam txhab tsim khoom yuav tsum tau ua kom tiav los ntawm 2018 raws li kev cai ntawm FDA. Qee cov khoom noj tseem muaj cov rog trans; nyob rau hauv cov khoom noj xws li cov nqaij tsiaj xws li nyuj cov nqaij, trans rog ib txwm tshwm sim.
Qhov txawv ntawm Hydrogenated thiab Ib nrab Hydrogenated Roj yog dab tsi?
Qhov sib txawv tseem ceeb ntawm cov roj hydrogenated thiab cov roj hydrogenated ib nrab yog cov roj hydrogenated yog cov roj uas muaj tag nrho cov C=C bonds txo, whereas ib nrab hydrogenated roj yog cov roj uas muaj qee qhov C=C bonds hloov thiab qee C=C bonds unchanged. Tsis tas li ntawd, cov roj hydrogenated muaj cov roj tsawg lossis tsis muaj roj trans, thaum cov roj hydrogenated ib nrab muaj cov roj trans rog ntau heev.
Cov hauv qab no qhia txog qhov sib txawv ntawm cov roj hydrogenated thiab ib nrab hydrogenated roj hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Hydrogenated vs Ib nrab Hydrogenated Roj
Cov roj hydrogenated yog cov roj uas muaj C=C bonds txo. Muaj ob hom roj hydrogenated li cov roj hydrogenated tag nrho thiab cov roj hydrogenated ib nrab. Qhov sib txawv tseem ceeb ntawm hydrogenated thiab ib nrab hydrogenated roj yog cov roj hydrogenated yog cov roj uas muaj tag nrho cov C=C bonds txo, whereas ib nrab hydrogenated roj yog cov roj uas muaj ib co ntawm cov C=C bonds hloov thiab ib co C=C bonds unchanged.
