Ndiyambe kunena kuti tiyi wobiriwira ndi chinthu chabwino.
Tiyi wobiriwira ali ndi zinthu zosiyanasiyana zogwira ntchito, zofunika kwambiri zomwe ndi tiyi polyphenols (chidule cha GTP), mankhwala ophatikizika amitundu yambiri ya hydroxyphenolic mu tiyi wobiriwira, wopangidwa ndi zinthu zopitilira 30 za phenolic, chigawo chachikulu ndi makatekisimu ndi zotuluka zawo. .Ma polyphenols a tiyi ali ndi antioxidant, anti-radiation, anti-aging, hypolipidemic, hypoglycemic, anti-bacterial and enzyme inhibiting physiological activities.
Pachifukwachi, tiyi wobiriwira akupanga chimagwiritsidwa ntchito mankhwala, chakudya, zinthu zapakhomo ndi pafupifupi kulikonse, kubweretsa zabwino zambiri kwa miyoyo ya anthu ndi thanzi.Komabe, tiyi wobiriwira, chinthu chofunidwa kwambiri chomwe chakhala chikuyenda bwino, mwadzidzidzi chatsanulidwa ndi European Union, chomwe chimati EGCG, chomwe chimagwira ntchito mu tiyi wobiriwira, ndi hepatotoxic ndipo chikhoza kuwononga chiwindi ngati chikugwiritsidwa ntchito. mochulukira.
Anthu ambiri omwe akhala akumwa tiyi wobiriwira kwa nthawi yayitali sakudziwa komanso amawopa ngati apitirize kumwa kapena kusiya.Palinso anthu ena omwe amakana zomwe EU ikunena, pokhulupirira kuti alendowa ali otanganidwa kwambiri, akungotulutsa thovu lonunkha nthawi ndi nthawi.
Mwachindunji, zotsatira zake zidachitika chifukwa cha Commission Regulation (EU) 2022/2340 yatsopano ya 30 Novembara 022, yosintha Annex III ku Regulation (EC) No 1925/2006 ya Nyumba Yamalamulo yaku Europe ndi Council kuti iphatikizepo tiyi wobiriwira wokhala ndi EGCG. m'ndandanda wa zinthu zoletsedwa.
Malamulo atsopano omwe akugwira ntchito kale amafuna kuti zinthu zonse zofunikira zomwe sizitsatira malamulowo ziziletsedwa kugulitsidwa kuyambira 21 June 2023.
Ili ndi lamulo loyamba padziko lonse lapansi loletsa zinthu zomwe zimagwira ntchito mu tiyi wobiriwira.Anthu ena angaganize kuti tiyi wobiriwira wa dziko lathu lakale ali ndi mbiri yakale, kodi ndi chiyani kwa EU?M'malo mwake, lingaliro ili ndilaling'ono kwambiri, masiku ano msika wapadziko lonse lapansi uli ndi thupi lonse, lamulo latsopanoli lidzakhudza kwambiri tsogolo la tiyi wobiriwira ku China, komanso mabizinesi ambiri kuti akhazikitsenso miyezo yopangira.
Tsono, kodi kuletsa kumeneku ndi chenjezo lakuti tiyeneranso kusamala za kumwa tiyi wobiriwira m’tsogolo, popeza kuchulukitsitsa kungawononge thanzi lathu?Tiyeni tiwunike.
Tiyi wobiriwira ali ndi tiyi wa polyphenols, chophatikizira ichi chimakhala ndi 20-30% ya kulemera kowuma kwa masamba a tiyi, ndipo zigawo zikuluzikulu za mankhwala mkati mwa tiyi polyphenols zimagawidwa m'magulu anayi a zinthu monga makatekini, flavonoids, anthocyanins, phenolic. zidulo, etc., makamaka zili apamwamba kwambiri catechins, mlandu 60-80% ya tiyi polyphenols.
Mkati mwa makatekini muli zinthu zinayi: epigallocatechin, epigallocatechin, epigallocatechin gallate ndi epigallocatechin gallate, yomwe epigallocatechin gallate ndi yomwe ili ndi EGCG yapamwamba kwambiri, yomwe imakhala 50-80% ya makatekini onse, ndipo ndi EGCG iyi yomwe ili yogwira ntchito kwambiri.
Ponseponse, gawo lothandiza kwambiri la tiyi wobiriwira paumoyo wamunthu ndi EGCG, chinthu chogwira chomwe chimapanga pafupifupi 6 mpaka 20% ya kulemera kowuma kwa masamba a tiyi.Lamulo latsopano la EU Regulation (EU) 2022/2340 limaletsanso EGCG, ikufuna kuti tiyi zonse zikhale ndi zosakwana 800mg za EGCG patsiku.
Izi zikutanthauza kuti mankhwala onse tiyi ayenera kukhala tsiku kudya zosakwana 800 mg wa EGCG munthu pa kutumikira kukula anasonyeza mu malangizo.
Izi zidakwaniritsidwa chifukwa mmbuyo mu 2015, Norway, Sweden ndi Denmark anali atapereka kale malingaliro ku EU kuti EGCG iphatikizidwe pamndandanda woletsedwa wokhudzana ndi zoopsa zomwe zingagwirizane ndi kumeza kwake.Kutengera izi, EU idapempha European Food Safety Authority (EFSA) kuti iwunikenso zachitetezo pa makatekisimu a tiyi wobiriwira.
EFSA yawunika mu mayeso osiyanasiyana kuti EGCG yochulukirapo kuposa kapena yofanana ndi 800 mg patsiku ingayambitse kuchuluka kwa seramu transaminases ndikuwononga chiwindi.Zotsatira zake, lamulo latsopano la EU limayika 800 mg ngati malire a kuchuluka kwa EGCG muzinthu za tiyi.
Ndiye kodi tiyenera kusiya kumwa tiyi m’tsogolo, kapena kusamala kuti tisamamwe kwambiri tsiku lililonse?
M’malo mwake, tidzatha kuona mmene chiletsochi chimakhudzira kumwa tiyi wobiriwira mwa kuchita mawerengedwe ang’onoang’ono.Kutengera kuwerengera kuti EGCG imakhala pafupifupi 10% ya kulemera kowuma kwa masamba a tiyi, 1 tael ya tiyi imakhala ndi pafupifupi 5 magalamu a EGCG, kapena 5,000 mg.Chiwerengerochi chikuwoneka chowopsa, ndipo pamlingo wa 800 mg, EGCG mu 1 tael ya tiyi imatha kuwononga chiwindi kwa anthu 6.
Komabe, zoona zake n'zakuti EGCG zili mu tiyi wobiriwira zimasiyanasiyana kwambiri malinga ndi kapangidwe tiyi zosiyanasiyana ndi ndondomeko kupanga, ndipo milingo izi zonse yotengedwa milingo, amene si onse kupasuka mu tiyi brew ndi, malingana ndi kutentha. m'madzi, zingayambitse EGCG kutaya ntchito yake.
Choncho, EU ndi maphunziro osiyanasiyana sapereka deta ya kuchuluka kwa tiyi komwe kuli kotetezeka kuti anthu amwe tsiku ndi tsiku.Anthu ena amawerengera, kutengera deta yoyenera yofalitsidwa ndi EU, kuti kudya 800 mg wa EGCG, angafunikire kudya 50 mpaka 100 g masamba a tiyi owuma kwathunthu, kapena kumwa pafupifupi 34,000 ml ya tiyi wobiriwira.
Ngati munthu ali ndi chizolowezi kutafuna 1 tael ya tiyi youma tsiku lililonse kapena kumwa 34,000 ml ya msuzi wamphamvu wa tiyi tsiku lililonse, ndi nthawi yoti mufufuze chiwindi ndipo zikutheka kuti kuwonongeka kwa chiwindi kwachitika.Koma zikuwoneka kuti pali ochepa kwambiri kapena palibe anthu oterowo, kotero sikuti palibe vuto lililonse kuti anthu azikhala ndi chizolowezi chomwa tiyi wobiriwira tsiku ndi tsiku, pali ubwino wambiri.
Chofunikira kudziwa apa ndikuti anthu omwe amakonda kumwa tiyi wouma kapena kumwa tiyi wochuluka kwambiri tsiku lonse ayenera kukhala ochepa.Chofunika kwambiri ndi chakuti anthu omwe ali ndi chizolowezi chomwa mankhwala owonjezera omwe ali ndi tiyi wobiriwira monga makatekini kapena EGCG ayenera kuwerenga zolembazo mosamala kuti awone ngati zidzapitirira 800 mg ya EGCG patsiku kuti athe kuteteza kuopsa. .
Mwachidule, malamulo atsopano a EU ndi azinthu zopangira tiyi wobiriwira ndipo sangakhudze kwambiri zomwe timamwa tsiku lililonse.
