Chokoreti yemukaka inodiwa nevatengi pasi rese nekuda kwekutapira kwayo uye kunyorova.Iyi dessert inogona kuwanikwa mumhando dzose dzezvokudya, asi haina hutano hwakakwana.Kusiyana neizvi, chokoreti yakasviba ine yakakwirira ye phenolic compounds, iyo inogona kupa antioxidant hutano hunobatsira, asiwo yakaoma, chocolate inovava.Nhasi, vatsvakurudzi vanotaura nzira itsva yekubatanidza chokoreti yemukaka nemarara ematehwe enzungu uye zvimwe zvinhu zvinorasa kuti iwedzere antioxidant zvayo.
Vatsvakurudzi vakapa migumisiro yavo paAmerican Chemical Society (ACS) Virtual Conference uye Expo muFall 2020. Musangano wakapera nezuro waiva nemisoro yakawanda yesayenzi, ine zvidzidzo zvinopfuura 6,000.
"Pfungwa yepurojekiti yakatanga nekuyedza zviitiko zvebiology zvemhando dzakasiyana dzemarara ekurima, kunyanya matehwe enzungu," akadaro Lisa Dean, muongorori mukuru wechirongwa ichi."Chinangwa chedu chekutanga chaive chekubvisa phenols kubva paganda uye kutsvaga nzira yekuasanganisa nechikafu."
Vagadziri pavanogocha nokugadzira nzungu kuti vagadzire nzungu, zviwitsi, uye zvimwe zvinhu, vanorasa bepa dzvuku reganda rinoputira bhinzi mumakwati.Zviuru zvematani ematehwe enzungu anoraswa gore rega rega, asi sezvo aine 15% phenolic compounds, iwo anogona kuve mugodhi wegoridhe wekuita antioxidant biological chiitiko.Antioxidants haingopi anti-inflammatory health benefits, asiwo inobatsira kudzivirira kukanganisa kwechikafu.
Muchokwadi, kuvepo kwechisikigo kwe phenolic komputa kunopa yakasviba chokoreti kuravira kunorwadza.Kuenzaniswa necousin mukaka chokoreti, ine mafuta mashoma uye shuga.Mhando dzakasviba dzinodhurawo kupfuura mhando dzemukaka nekuda kwehuwandu hwadzo hwecocoa, saka kuwedzerwa kwemarara sematehwe enzungu kunogona kupa mabhenefiti akafanana uye haadhure.Makanda enzungu haasi iwo ega tsvina yechikafu inogona kuwedzera mukaka chokoreti nenzira iyi.Vatsvagiri vari kutsvagawo nzira dzekubvisa uye nekubatanidza phenolic makomisheni kubva mumarara ekofi nzvimbo, marara tii uye zvimwe zvinosara zvekudya.
Kugadzira chokoreti yavo yemukaka inowedzerwa antioxidant, Dean nevaongorori vake vekuUnited States Department of Agriculture (USDA) Agricultural Research Service vakashanda nekambani yenzungu kuti vawane matehwe enzungu.Kubva ipapo, vanokuya ganda kuita hupfu vobva vashandisa 70% ethanol kubvisa phenolic compounds.Iyo lignin ne cellulose yasara inogona kushandiswa sechikafu chemhuka kuitira roughage.Vanoshandawo nevabiki vekofi vemunharaunda uye vagadziri vetii kushandisa nzira dzakafanana kubvisa maoxidants kubva muzvinhu izvi kuti vawane nzvimbo dzekofi dzakashandiswa uye mashizha etii.Iyo phenolic powder inobva yasanganiswa neyakajairwa chikafu chekuwedzera maltodextrin kuita kuti zvive nyore kuisa mukati mekupedzisira mukaka chokoreti chigadzirwa.
Kuti vaone kuti dessert yavo itsva inogona kupfuudza mutambo wekudya, vaongorori vakagadzira imwe sikweya chokoreti umo kuunganidzwa kwe phenols kunobva ku0.1% kusvika 8.1%, uye munhu wese ane pfungwa yakadzidziswa kuravira.Chinangwa ndechekuita kuti phenolic powder mukuravira kwechokoreti yemukaka isingaoneki.Vanoedza kuravira vakawana kuti huwandu hunodarika 0.9% hunogona kuonekwa, asi kuiswa kwephenolic resin pahuwandu hwe0.8% kunogona kukanganisa huwandu hwehupenyu hwehupenyu pasina kupira flavour kana magadzirirwo.Muchokwadi, inopfuura hafu yevanoedza kuravira vakasarudza 0.8% phenolic mukaka chokoreti kune isingadzoreki mukaka chokoreti.Sample iyi ine yakakwira makemikari antioxidant chiitiko pane akawanda erima machokoreti.
Kunyangwe mhedzisiro iyi ichikurudzira, Dean nechikwata chake chekutsvagisa vanobvumawo kuti nzungu idambudziko guru rekudya.Vakaedza phenolic poda yakagadzirwa kubva paganda nekuda kwekuvapo kwealeji.Kunyange hazvo pasina zvinodzivirira zvirwere zvakawanikwa, vakati zvigadzirwa zvine ganda renzungu zvinofanira kuramba zvichinzi zvine nzungu.
Tevere, vaongorori vanoronga kuenderera mberi nekuongorora kushandiswa kwematehwe enzungu, nzvimbo dzekofi uye zvimwe zvinoraswa zvezvimwe zvikafu.Kunyanya, Dean anotarisira kuyedza kana iyo antioxidants mumatehwe enzungu inogona kuwedzera hupenyu hwesherufu yenzungu butter, inogona kuora nekukurumidza nekuda kwehuwandu hwemafuta.Kunyangwe kutengeswa kwechokoreti yakawedzerwa kuchiri kure uye kuchida kupihwa patent nekambani, vanovimba kuti kuedza kwavo kunozopedzisira kwaita kuti chokoreti yemukaka pamasherufu esupermarket ive nani.
