Cov margarine yog lub npe siv rau kev hloov roj. Raws nraim thaum cov khoom no tau tsim tawm tsis tau paub. Nws yog qhov tseeb tias xyoo 1960, Fab Kis Napoleon III tshaj tawm tus nqi zog rau txhua tus uas tsim kev txaus siab rau cov roj uas tsim nyog siv rau cov tub rog thiab cov chav kawm qis. Tus kws tshuaj Fabkis hu ua Hippolyte Mege-Maurice tau tsim cov khoom hu ua "oleomargarine", uas tom qab ntawv luv rau "margarine".

Margarine ua raws li cov txheej txheem tsim cov khoom siv tshuaj hydrogenation, uas yog tsim los ntawm nws tus neeg nrhiav kom tau lub zog ntawm cov tshuaj ntxuav tes. Tsis ntev tom qab pom ntawm margarine, nws tau nce ntau dua cov neeg. Nws tau tsiv los ntawm Fab Kis mus rau Tebchaws Asmeskas, thiab los ntawm 1873 lub lag luam hloov roj tau ua tiav zoo heev.

Txij li thaum nruab nrab xyoo 1980s, Tsoomfwv Meskas tsoomfwv tau tshaj tawm cov se ntawm 2 xees ib phaus, nrog rau daim ntawv tso cai kim heev los tsim thiab muag cov roj qab rog. Qee lub xeev tau pib xav tias nws yuav tsum muaj ntawv cim meej thiab tsis ua qhov tsis muaj roj.

Cov dab neeg dhau los ntawm ntau theem, kev tsis kam lees, txhim kho, txwv tsis pub tshaj tawm thiab kev tshaj tawm ntawm margarine kom mus txog rau hnub no, thaum cov khoom no yog qhov muag tshaj tawm cov khoom lag luam hauv qee qhov chaw ntawm lub ntiaj teb. Nws cov txheej txheem niaj hnub tsim raws li ntau cov tsiaj lossis zaub mov rog thiab feem ntau yog sib xyaw nrog skim mis, ntsev thiab emulsifiers.

Cov kab mob nrov heev niaj hnub no yog sib xyaw ntawm cov roj qab zib thiab cov roj butter - yam uas tau ua txhaum ntev ntev hauv Tebchaws Asmeskas thiab Australia, thiab lwm qhov hauv ntiaj teb. Hauv Tebchaws Meskas, piv txwv li, xyoo 1930, ib tus neeg haus cov roj qab ntsev ntau dua 8 kg (18 phaus) thiab tsuas yog ntau dua 900 g (2 phaus) ntawm margarine. Txog rau thaum xaus ntawm lub xyoo pua 20, qhov nruab nrab Asmeskas noj qis dua 1.8 kg (4 phaus) ntawm butter thiab ze li 3.6 kg (8 phaus) ntawm margarine.

Koj feem ntau nug koj tus kheej seb margarine yog ib qho khoom noj muaj txiaj ntsig zoo li cas thiab nws muaj txiaj ntsig zoo li cas / tsis pom zoo ntawm tib neeg kev noj qab haus huv.

Piv txwv li, cov roj lossis lwm cov roj ua noj ua rog yog kua. Ua kom dhau los ua cov khoom ruaj khov, cov khoom yog rhuab mus rau qhov kub siab heev hauv qab kev kub siab.

Hydrogen yog tom qab ntawd tau muab coj los tso rau hauv qhov sib xyaw nyob rau hauv muaj cov npib tsib xee thiab txhuas ua catalysts. Hydrogen cov lwg me ua ke nrog cov pa roj carbon los ua cov khoom cua ntawm lub cev hu ua margarine.

Hauv nws daim ntawv qub, cov lus no dub hauv cov xim thiab tsw ntxhiab tsw phem. Txhawm rau ua cov margarine uas peb yuav hauv khw muag khoom, peb dhau los ntawm cov tshuaj dawb (zoo ib yam li cov ntxhua khaub ncaws), pleev xim, ntxiv tshuaj, ntxiv rau tshuaj tsw qab, thiab qee zaum ntxiv cov vitamins.

Txawm li cas los xij, tseem muaj qee cov teeb meem tseem ceeb thaum peb tham txog margarine ua zaub mov tiav.

Roj

Thawj tus yog cuam tshuam nrog lub ntsiab ntawm hydrogenation - kev ua kom muaj cua sov thiab kev ua tiav ntawm cov roj rhuav tshem tag nrho cov vitamins thiab minerals, hloov cov khoom sib xyaw.

Thib ob, cov roj ntsha tseem ceeb (Qhov tseem ceeb Fatty Acids) tau hloov thiab qee zaus txawm tig mus ua cov khoom xyaw kev ua txhaum, piv txwv li. hloov chaw pab lawv tau muaj teeb meem. Raws li kev tshawb fawb los ntawm Dr. Hugh Sinclair, lub taub hau ntawm lub chaw soj ntsuam kev noj zaub mov hauv tib neeg ntawm Oxford University, qhov tsis muaj cov roj ntsha "ua rau muaj kab mob rau cov hlab ntsha, mob plawv, atherosclerosis, kab mob ntawm daim tawv nqaij, mob caj dab thiab mob cancer."

Qhov teeb meem thib peb nrog kev noj zaub noj ntawm margarine - cov tshuaj tshwm sim tsis pom zoo los ntawm lub cev. Yog li, nws raug kho raws li cov khoom siv txawv teb chaws thiab tus nqi uas tsis muab pov tseg yog tso rau hauv cov roj ntsha. Cov txiaj ntsig ntawm cov rog no, ib sab los ntawm kev noj qab haus huv tsis zoo, yog qhov nce rau hauv cov rog rog.

Qhov teeb meem thib plaub loj yog qhov muaj cov nickel hauv cov txheej txheem ntau lawm, uas tseem nyob hauv cov margarine. Raws li cov kws tshuaj, nickel tsis tuaj yeem raug lim, tsis hais tus qauv siv. Hauv kev tsim cov khoom lag luam rau cov roj qab rog, npib tsib xee yog txhaj rau hauv qhov me me.

Nws feem pua yog li ntawm 0.5 txog 1 feem pua. Cov txheej txheem pheej yig ntawm cov khoom lag luam muaj qhov txaus ntshai tshaj - qhov sib npaug sib xyaw ntawm nickel thiab aluminium yog siv, uas, txawm li cas los xij, kom muaj cov txiaj ntsig, qhov kev siv nyiaj tau nce los ntawm ib mus txog kaum feem pua ntawm qhov hnyav ntawm cov khoom.

Raws li cov kws tshaj lij Dr. Henry A Schroeder, nickel, txawm tias hauv kev txhaj tshuaj tsawg kawg nkaus, yog cov kabmob carcinogenic. Ntxiv mus, hlau tsis xam qhov tshwm sim hauv tib neeg lub cev, xws li npib tsib xee, tau kawm ua tus mob atherosclerosis.

Ib qho hlau tuaj yeem hloov tau lwm qhov thiab hloov nws los ntawm kev siv roj ntsha, yog li npib tsib xee yuav muaj kev sib tw nrog lwm qhov, qhov tseem ceeb tshaj plaws, cov hlau hauv lub cev enzyme thiab pab txhawb cov vitamin B6 tsis txaus, tus kws kho mob tau hais.
