Qhov sib txawv tseem ceeb ntawm anthocyanins thiab anthoxanthins yog cov anthocyanins yog ib pawg ntawm xiav, liab, lossis ntshav pigments pom nyob rau hauv cov nroj tsuag, thaum anthoxanthins yog ib pawg dawb lossis daj xim pigments pom hauv cov nroj tsuag.
Pigments yog cov khoom sib txuas uas muaj xim tshwj xeeb thiab siv dav hauv cov xim ntawm cov ntaub ntawv. Pigments tseem hu ua lom pigments los yog biochromes raws li lawv yog cov xim tiag tiag pom hauv cov nroj tsuag thiab tsiaj txhu. Anthocyanins thiab anthoxanthins yog ob pawg ntawm cov nroj tsuag pigments.
Anthocyanins yog dab tsi?
Anthocyanins yog xiav, liab, lossis ntshav pigments pom hauv cov nroj tsuag. Cov pigments no muab xim rau paj, txiv hmab txiv ntoo, thiab tubers. Lawv kuj hu ua anthocyans. Lawv yog cov dej-soluble vacuolar pigments. Nyob ntawm pH, cov xim no tuaj yeem tshwm liab, ntshav, xiav, lossis dub. Lub npe no tau tsim thawj zaug los ntawm tus kws muag tshuaj German Ludwig Clamor Marquart hauv xyoo 1835. Qee cov zaub mov cog uas muaj anthocyanins muaj xws li blueberry, raspberry, dub nplej, thiab taum dub. Ntxiv mus, qee cov xim ntawm lub caij nplooj zeeg nplooj kuj tau muab los ntawm anthocyanins.
Daim duab 01: Anthocyanins
Anthocyanins tshwm sim hauv txhua cov ntaub so ntswg ntawm cov nroj tsuag siab dua, suav nrog nplooj, stems, cag, paj, thiab txiv hmab txiv ntoo. Lawv pib los ntawm anthocyanidins los ntawm kev ntxiv qab zib molecules rau cov qauv. Anthocyanins feem ntau tsis muaj ntxhiab thiab tsis muaj zog. Anthocyanins belongs rau niam txiv chav kawm ntawm cov tebchaw hu ua flavonoids synthesized los ntawm txoj kev phenylpropanoid. European Union tau pom zoo siv cov tshuaj anthocyanins rau xim zaub mov thiab dej haus. Txawm li cas los xij, lawv tsis raug pom zoo siv los ua cov khoom noj ntxiv vim tias lawv tsis tau lees paub tias muaj kev nyab xeeb thaum siv los ua cov khoom xyaw ntxiv. Tsis tas li ntawd, tsis muaj pov thawj tseeb los ua pov thawj tias anthocyanins ua lub luag haujlwm hauv tib neeg cov kab mob.
Anthoxanthins yog dab tsi?
Anthoxanthins yog xim dawb lossis creamy daj pom hauv cov nroj tsuag, tshwj xeeb tshaj yog nyob rau hauv paj paj. Lawv yog cov yeeb yuj flavonoid pigments muaj nyob hauv cov nroj tsuag. Lawv kuj yog dej-soluble nyob rau hauv cov xwm. Anthoxanthins hloov lawv cov xim raws li pH hauv nruab nrab. Yog li ntawd, lawv yog whiter nyob rau hauv ib tug acid nruab nrab thiab yellowish nyob rau hauv ib tug alkaline nruab nrab. Zoo ib yam li anthocyanins, anthoxanthins kuj raug rau cov xim hloov nrog cov zaub mov thiab hlau ions.

Zoo li txhua yam flavonoids, anthoxanthins kuj muaj cov khoom antioxidant. Anthoxanthins yog siv hauv kev lag luam zaub mov ua khoom noj khoom haus. Yog li ntawd, lawv muaj txiaj ntsig zoo heev. Anthoxanthins uas tsaus nti nrog hlau yog qhov tshwj xeeb hauv cov khoom noj. Tsis tas li ntawd, lawv suav hais tias muaj ntau yam ntau dua li anthocyanins. Qee qhov piv txwv ntawm anthoxanthins yog quercetin, betaxanthin, thiab canthaxanthin.
Dab tsi zoo sib xws ntawm Anthocyanins thiab Anthoxanthins?
- Anthocyanins thiab anthoxanthins yog ob hom cog pigments
- YLawv yog flavanoids.
- Ob lub pigments muaj qhov cuam tshuam rau cov xim hloov nrog cov ntxhia thiab hlau ions.
- Ob lub xim yog dej-soluble.
- YLawv muaj cov tshuaj antioxidant.
Qhov txawv ntawm Anthocyanins thiab Anthoxanthins yog dab tsi?
Anthocyanins yog xiav, liab, lossis ntshav pigments pom nyob rau hauv cov nroj tsuag, thaum anthoxanthins yog dawb, creamy, los yog daj pigments pom nyob rau hauv cov nroj tsuag. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm anthocyanins thiab anthoxanthins. Tsis tas li ntawd, anthocyanins suav hais tias muaj ntau yam tsawg dua piv rau anthoxanthins, thaum anthoxanthins suav tias muaj ntau yam piv rau anthocyanins. Ntxiv mus, anthocyanins tsis siv los ua zaub mov ntxiv, thaum anthoxanthins tuaj yeem siv los ua zaub mov ntxiv.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm anthocyanins thiab anthoxanthins hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Anthocyanins vs Anthoxanthins
Muaj plaub yam xim loj pom hauv cov nroj tsuag. Cov no yog chlorophyll, carotenoids, anthocyanins, thiab anthoxanthins. Lawv tseem hu ua biological pigments. Anthocyanins yog xiav, liab, lossis ntshav pigments pom nyob rau hauv cov nroj tsuag, thaum anthoxanthins yog dawb los yog creamy daj pigments pom nyob rau hauv cov nroj tsuag. Lawv yog flavonoids, thiab ob qho tib si muaj antioxidant zog. Anthocyanins yog siv los ua xim zaub mov thiab dej haus, thaum anthoxanthins yog siv los ua zaub mov additives. Yog li, qhov no qhia txog qhov sib txawv ntawm anthocyanins thiab anthoxanthins.
