Puas yog avocado siab hauv polyphenols?

Hauv pantheon ntawm cov zaub mov noj qab haus huv, Avocado (lub npe tshawb fawb Persea Americana) tau tuav lub zwm txwv ntev li "superfood" vim nws cov ntsiab lus nplua nuj ntawm monounsaturated fatty acids, vitamins, thiab minerals. Txawm li cas los xij, rau cov kws kho mob hauv kev lag luam cog qoob loo, cov lus nug tseem ceeb ntawm kev lag luam yog tsim nyog xav txog: Puas muaj "polyphenol treasure trove" uas tsis tau muab zais rau hauv cov txiv hmab txiv ntoo pov tseg thiab cov pits ntawm cov neeg siv khoom?

Polyphenolsyog hom metabolite thib ob uas tsim los ntawm cov nroj tsuag thaum lub sijhawm loj hlob los tiv thaiv UV hluav taws xob thiab cov kab mob ntxeem tau, thiab muaj nyob hauv cov txiv hmab txiv ntoo, zaub, tshuaj yej, thiab lwm yam nroj tsuag. Polyphenols tau nyiam ntau yam vim lawv cov haujlwm lom neeg muaj zog, xws li antioxidant, tiv thaiv - mob, thiab cov kab mob tua kab mob (Source: Natural Products Research thiab Development, 2024). Hauv kev lag luam khoom noj khoom haus, lawv tuaj yeem ua cov tshuaj tiv thaiv ntuj thiab cov tshuaj tua kab mob antioxidant, ncua cov khoom txee lub neej; Hauv kev lag luam ntawm cov khoom noj qab haus huv thiab cov khoom noj ua haujlwm, lawv yog cov khoom tseem ceeb uas txhim kho kev tiv thaiv kab mob thiab txhim kho cov hlab plawv; Hauv kev lag luam tshuaj pleev ib ce, lawv tiv thaiv - kev laus thiab kev tiv thaiv ntawm daim tawv nqaij kuj tau siv dav.

Rov qab mus rau lo lus nug tseem ceeb: Puas yog avocado siab hauvpolyphenols? Cov lus teb tsis yog ib qho yooj yim 'yog' lossis 'tsis yog', tab sis yog cov lus nug txog kev tshawb fawb zoo thiab segmented. Kev lig kev cai, peb tsuas yog haus cov nqaij ntawm avocados, thaum daim tawv nqaij thiab cov tub ntxhais, uas suav txog li 30% ntawm tag nrho qhov hnyav, raug kho raws li kev ua liaj ua teb pov tseg.

• 2.1 Pulp: maj mam contributor

Avocado nqaij muaj polyphenols, feem ntau suav nrog phenolic acids (xws li caffeic acid thiabferulic acid) thiab flavonoids (xws li catechins, epicatechins, thiabanthocyanins). Raws li kev txheeb xyuas tag nrho ntawm Hass avocado ntau yam luam tawm nyob rau hauv Phau Ntawv Qhia Txog Kev Ua Liaj Ua Teb thiab Khoom Noj Chemistry hauv xyoo 2023, tag nrho cov ntsiab lus phenolic (TPC) ntawm nws cov nqaij yog feem ntau nyob rau hauv thaj tsam ntawm 50-150 milligrams ntawm gallic acid sib npaug ib 100 grams ntawm qhov hnyav tshiab (mg GAE / 100g FW). Qhov txiaj ntsig no tsis yog tshwj xeeb tshaj yog piv rau "polyphenolic berries" xws li blueberries (kwv yees li 200-500 mg GAE / 100g FW) lossis pomegranates (kwv yees li 150-350 mg GAE / 100g FW). Yog li ntawd, yog tias tsuas yog cov nqaij siv los ua qhov ntsuas ntsuas, avocado tsis yog ib tus tswv cuab ntawm cov ntsiab lus polyphenol ntau tshaj echelon.

• 2.2 Peel: ib qho underestimated 'sab tshos sab nrauv'

Cov tawv nqaij ntawm avocado yog thawj kab ntawm kev tiv thaiv ib puag ncig sab nraud; yog li ntawd, nws yog enriched nrog ib tug loj npaum li cas ntawm tiv thaiv compounds - polyphenols. Ib txoj kev tshawb fawb luam tawm nyob rau hauv phau ntawv Journal Food Science thiab Technology hauv 2024 pom tias tag nrho cov ntsiab lus phenolic ntawm avocado tev yog qhov txaus ntshai heev, nrog rau qhov hnyav tag nrho cov phenolic cov ntsiab lus ntawm 2000-4000 milligrams ntawm gallic acid sib npaug ib 100 grams (mg GAE / 100g DW), uas yog ntau tshaj 20 lub sij hawm cov ntsiab lus ntawm cov txiv hmab txiv ntoo 20 zaug (cov ntaub ntawv, cov ntaub ntawv 20 npaug ntawm cov khoom siv hluav taws xob). Lub ntsiabpolyphenolskuaj pom nyob rau hauv cov txiv hmab txiv ntoo tev yog anthocyanins, catechins, thiab ntau yam flavonol glycosides, uas muaj zog antioxidant kev ua. Qhov no qhia tau hais tias tus nqi ntawm avocado tev raws li cov khoom siv raw rau kev rho tawm deb tshaj peb qhov kev xav.

• 2.3 Noob: Qhov tseeb "polyphenol core"

Yog tias daim tawv nqaij yog khoom muaj nqis, ces avocado core yog 'core engine' ntawm cov khoom muaj nqis no. Nws suav rau 13-18% ntawm avocado tag nrho qhov hnyav tab sis concentrates feem ntau ntawm cov txiv hmab txiv ntoo cov tshuaj bioactive. Ib txoj kev tshawb fawb los ntawm Lub Tsev Kawm Ntawv ntawm Food Science thiab Nutrition Engineering ntawm Tuam Tshoj Agricultural University hauv 2023 tau qhia tias tag nrho cov ntsiab lus phenolic ntawm avocado kernels yog qhov siab tshaj plaws ntawm txhua qhov chaw, thiab tag nrho cov ntsiab lus phenolic ntawm nws cov hmoov qhuav tuaj yeem ncav cuag 5000-8000 milligrams ntawm gallic acid sib npaug ib 100 grams ntawm cov khoom noj (mgW) thiab cov ntaub ntawv Science DAE. Nutritional Engineering, Tuam Tshoj Agricultural University, cov ntaub ntawv tshawb fawb sab hauv hauv 2023). Ntau cov ntaub ntawv qhia tias avocado kernels account rau ntau tshaj 70% ntawm cov txiv hmab txiv ntoo lub peev xwm antioxidant. Nws cov khoom xyaw tseem ceeb tsis yog tsuas yog suav nrog ntau cov anthocyanins thiab catechins, tab sis kuj muaj ib qho tshwj xeeb lipid molecule hu ua "Avocatin B", uas tau pom muaj peev xwm loj hauv kev tshawb fawb los tiv thaiv qog.
