Los ntawm proanthocyanidins hauv cov txiv hmab txiv ntoo mus rau catechins hauv tshuaj yej ntsuab, ntuj polyphenols yog nrhiav tau rau lawv cov khoom muaj zog antioxidant thiab cov txiaj ntsig kev noj qab haus huv. Yog li, qhov twg yog ib qho ntawm cov txiv hmab txiv ntoo uas muaj ntau tshaj plaws hauv peb lub neej niaj hnub- txiv apples- sawv hauv qhov "nplua nuj kuv" ntawm polyphenols?
1. Kua Polyphenols: Txhais thiab Core Value
Ua ntej, peb yuav tsum qhia meej tias cov kua polyphenols yog dab tsi. Kua polyphenols tsis yog ib qho kev sib xyaw ua ke tab sis ib lub sij hawm sib sau ua ke rau ntau yam phenolic muaj nyob hauv cov txiv apples. Cov tshuaj no feem ntau suav nrog cov tshuaj flavonol (xws li quercetin thiab nws cov glycosides), flavan-3-ols (xws li catechin, epicatechin, thiab proanthocyanidins), phenolic acids (xws li chlorogenic acid), thiab dihydrochalcones (xws li phloridzin).[1] Nws yog qhov tseeb ntawm cov khoom sib txawv no uas sib sau ua lub hauv paus kev ua haujlwm lom neeg muaj zog ntawm cov txiv apples, ua rau lawv ua kom pom qhov muaj peev xwm tseem ceeb hauv thaj chaw xws li tshuaj tiv thaiv kab mob antioxidant, kev tiv thaiv kab mob plawv, thiab txawm tias cov khoom tiv thaiv qog noj ntshav.[1, 2]
2. Kua Polyphenol Cov Ntsiab Lus: Ib Lub Ntsiab Lus Tag Nrho ntawm Kev Hloov Pauv
Yog li, ntau npaum li cas cov ntsiab lus polyphenol hauv txiv apples? Lo lus nug yooj yim zoo li no yog qhov nyuaj los teb hauv ib nqe lus. Los ntawm kev tshuaj xyuas cov ntaub ntawv tshawb fawb uas twb muaj lawm, peb pom tias ntau yam tseem ceeb cuam tshuam rau nws cov ntsiab lus.
2.1 Ntau Qhov Sib Txawv: Qhov "Cenetic" Variations hauv Polyphenol Cov ntsiab lus
Muaj qhov sib txawv tseem ceeb hauv cov ntsiab lus polyphenol ntawm ntau hom txiv apples, qhov tseeb tau lees paub dav hauv kev lag luam. Piv txwv li, ib txoj kev tshawb fawb soj ntsuam 15 ntau hom txiv apples pom muaj qhov txawv txav hauv lawv cov qib polyphenol (TP) tag nrho. [105] Qee qhov kev tshawb fawb tau muab cov ntaub ntawv tshwj xeeb ntau ntxiv:
- Fuji Apples: Raws li cov khoom lag luam tseem ceeb hauv kev ua lag luam, Fuji txiv apples muaj cov qib siab ntawm cov phenolic tebchaw. Cov ntaub ntawv tshawb fawb qhia lawv cov ntsiab lus mus txog 230 mg / 100 g. Lwm txoj kev tshawb fawb txog browning thaum lub sij hawm cia ntsuas tag nrho cov ntsiab lus phenolic hauv Fuji kua nqaij ntawm 726.0 mg / kg (piv txwv li, 72.6 mg / 100 g).[4]
- Kozara Kua: Ib txoj kev tshawb fawb 2024 tau qhia tias "Kozara" kua ntau yam, nrog rau tag nrho cov ntsiab lus polyphenol ntawm 217.37 mg GAE / 100g tshiab qhov hnyav (fw), sawv tawm ntawm ntau hom kev sim.
- Lwm hom: Kev tshawb fawb qhia tias tag nrho cov ntsiab lus phenolic nyob ntawm 66.2 mus rau 211.9 mg / 100 g tshiab qhov hnyav, thiab tuaj yeem ncav cuag qhov xav tsis thoob 2723.96 mg / 100 g qhuav qhov hnyav hauv qee hom thiab qee yam mob. Cov ntsiab lus ntawm polyphenol ntawm ntau yam xws li Golden Delicious, Gala, thiab Granny Smith kuj tau kawm ntau yam.[3]
2.2 Kev faib tawm los ntawm Ib Ntu: Kua tev yog qhov tseeb "polyphenol cov khoom muaj nqis."
Kev faib tawm ntawmtxiv apples polyphenolsNws yog qhov tsis sib xws, nrog cov ntsiab lus siab dua hauv cov tev ntau dua li hauv cov nqaij. Ntau qhov kev tshawb fawb tsis tu ncua paub meej tias tag nrho cov ntsiab lus phenolic hauv cov kua txiv hmab txiv ntoo tuaj yeem ua tau ob peb zaug ntawm cov nqaij.
Rov qab mus rau peb lo lus nug qub: Puas yog cov ntsiab lus polyphenol hauv cov txiv apples siab? Lo lus teb yog yog- txiv apples yog undoubtedly ib tug tseem ceeb noj ntawm polyphenols. Txawm li cas los xij, rau cov nroj tsuag extract kev lag luam uas muaj qhov tseem ceeb ntawm kev tsim qauv thiab kev ua haujlwm siab, "siab" yog lub tswv yim txheeb ze thiab muaj zog. Cov ntsiab lus polyphenol hauv txiv apples txawv txawv nyob ntawm ntau yam. Tsis tas li ntawd, cov txheej txheem ua haujlwm ncaj qha txiav txim siab qhov kawg ntawm cov ntsiab lus polyphenol hauv cov khoom.
