Kuthetsa

Hexane imachotsedwa mu njere ya canola poitenthetsa kachitatu pa 95-115 °C potenthedwa ndi nthunzi.

Kukonza mafuta

Mafuta ochotsedwa amayengedwa ndi njira zosiyanasiyana monga kusungunula nthunzi, kukhudzana ndi phosphoric acid, ndi kusefedwa kudzera mu dongo lopangidwa ndi asidi.

Zowona Zazakudya Zamafuta a Canola

Monga mafuta ena ambiri, canola si gwero labwino lazakudya. Supuni imodzi (15 ml) mafuta a canola Lili ndi zakudya izi:

Zopatsa mphamvu: 124

Vitamini E: 12% ya Reference Daily Intake (RDI)

Vitamini K: 12% ya RDI

Kupatula mavitamini E ndi K, mafutawa alibe mavitamini ndi mchere.

Kupanga kwamafuta acid

Mafuta a Canola nthawi zambiri amatchulidwa kuti ndi amodzi mwamafuta abwino kwambiri chifukwa cha kuchepa kwamafuta ambiri. mafuta a canolaKuphatikizika kwa mafuta m'thupi kumakhala motere:

Mafuta ochulukirapo: 7%

Mafuta a monounsaturated: 64%

Mafuta a polyunsaturated: 28%

mafuta a canolaMafuta a polyunsaturated omwe ali mmenemo ali ndi 3% linoleic acid (odziwika bwino monga omega-21 fatty acid) ndi 6% alpha-linolenic acid (ALA), mtundu wa omega-11 fatty acid wochokera ku zomera.

Mafuta a Canola Owopsa

mafuta a canolandi chachiwiri kwa mafuta padziko lonse lapansi. Kugwiritsiridwa ntchito kwake muzakudya kukupitirirabe kuwonjezeka ndipo kwakhala chimodzi mwazinthu zotchuka kwambiri zamafuta muzakudya zamalonda.

Chifukwa chake kuwonongeka kwa mafuta a canola imabwera patsogolo kwambiri. Izi ndi Ziyani?

Mafuta ochulukirapo a omega-6

mafuta a canola mbaliChimodzi mwa izo ndi kuchuluka kwa mafuta a omega-6. Monga mafuta a omega-3, mafuta a omega-6 ndi ofunikira pa thanzi komanso amagwira ntchito zofunika m'thupi.

Koma zakudya zamakono zimakhala zapamwamba kwambiri za omega-6 zomwe zimapezeka muzakudya zambiri zoyengedwa, ndipo omega-3 otsika omwe amapezeka muzakudya zachilengedwe amayambitsa kusalinganika komwe kumayambitsa kutupa.

Ngakhale kuti chiŵerengero cha thanzi cha omega-6 mpaka omega-3 ndi 1: 1, chikuyembekezeka kukhala 15: 1 muzakudya wamba.

Kusalinganika uku Matenda a Alzheimer'sZimagwirizanitsidwa ndi matenda angapo osatha, monga kunenepa kwambiri ndi matenda a mtima. mafuta a canolaKuchuluka kwa omega-6 fatty acids m'zakudya kumayambitsa matenda.

Zambiri za GMO

Zakudya za GMO zimapangidwa ndi ma genetic kuti zitsimikizire kapena kuthetsa mikhalidwe ina.

Mwachitsanzo, mbewu zomwe zimafunidwa kwambiri monga chimanga ndi canola zidapangidwa kuti zizitha kugonjetsedwa ndi mankhwala ophera udzu ndi tizirombo.

Ngakhale kuti asayansi ambiri amaona kuti zakudya za GM n’zotetezeka, pali nkhawa zokhudza mmene zingakhudzire chilengedwe, thanzi la anthu, kuipitsidwa kwa mbewu, ufulu wa katundu, ndiponso chitetezo cha chakudya.

Zoposa 90% zazinthu za canola zimapangidwa ndi majini. Ngakhale kuti zakudya zamtundu wa GM zavomerezedwa kuti zigwiritsidwe ntchito kwa anthu kwa zaka zambiri, pali deta yochepa paziwopsezo za thanzi lawo, choncho kusamala kuli koyenera pakudya kwawo.

Woyengedwa kwambiri

Kupanga mafuta a canola poyera kutentha kwambiri ndi mankhwala nthawi Amaganiziridwa kuti ndi mafuta oyengedwa ndi mankhwala, canola amadutsa m'magawo amankhwala (monga bleaching ndi deodorizing).

Mafuta oyeretsedwa - canola, soya, chimanga ndi mafuta a kanjedza kuphatikizapo - zomwe zimadziwika kuti mafuta oyengedwa, oyeretsedwa komanso odetsedwa (RBD).

Njira yoyenga imachepetsa kwambiri zakudya zomwe zili mumafuta, monga mafuta ofunikira, ma antioxidants, ndi mavitamini.

wosayeretsedwa, wozizira mafuta a canola Ngakhale zilipo, canola ambiri pamsika amayengedwa kwambiri ndipo alibe ma antioxidants omwe amapezeka mumafuta osayengedwa monga mafuta owonjezera a azitona.

Kodi Mafuta a Canola Ndi Owopsa?

Ngakhale kuti ndi imodzi mwamafuta omwe amagwiritsidwa ntchito kwambiri m'makampani azakudya, pali maphunziro ochepa okhudza thanzi lake.

Komanso, akuti pali mafuta a canola amathandiza maphunziro ambiri opanga mafuta a canola mothandizidwa ndi. Umboni wina umasonyeza kuti mafutawa akhoza kusokoneza thanzi.
