Chokolete ea lebese e ratoa ke bareki lefatšeng ka bophara ka lebaka la monate oa eona le mokhoa oa eona o monate.Serosa sena se ka fumanoa mefuteng eohle ea lijo tse bobebe, empa ha se bophelo bo botle ka ho feletseng.Ka lehlakoreng le leng, tsokolate e lefifi e na le metsoako e phahameng ea phenolic, e ka fanang ka melemo ea bophelo bo botle ba antioxidant, empa hape ke chokolete e thata, e bohloko.Kajeno, bafuputsi ba tlaleha mokhoa o mocha oa ho kopanya chokolete ea lebese le matlalo a peanut a litšila le lisebelisoa tse ling tsa litšila ho ntlafatsa thepa ea eona ea antioxidant.
Bafuputsi ba ile ba hlahisa liphello tsa bona Sebokeng sa Virtual sa American Chemical Society (ACS) le Expo ka Fall 2020. Seboka se ileng sa fela maobane se ne se e-na le lihlooho tse ngata tsa saense, tse nang le lipuo tse fetang 6,000.
"Mohopolo oa morero o qalile ka ho hlahloba ts'ebetso ea likokoana-hloko tsa mefuta e fapaneng ea litšila tsa temo, haholo-holo matlalo a peanut," ho boletse Lisa Dean, mofuputsi ea ka sehloohong oa morero."Morero oa rona oa pele e ne e le ho ntša phenols letlalong le ho fumana mokhoa oa ho li kopanya le lijo."
Ha bahlahisi ba halika le ho lokisa matokomane ho etsa peanut butter, lipompong le lihlahisoa tse ling, ba lahla letlalo le khubelu la pampiri le phuthelang linaoa likhetleng tsa tsona.Lithane tse likete tsa matlalo a peanut li lahloa selemo se seng le se seng, empa kaha li na le 15% ea metsoako ea phenolic, ke morafo o ka bang teng oa khauta bakeng sa ts'ebetso ea likokoana-hloko ea antioxidant.Li-antioxidants ha li fane feela ka melemo ea bophelo bo botle bo khahlanong le ho ruruha, empa hape li thusa ho thibela ho senyeha ha lijo.
Ebile, boteng ba tlhaho ba metsoako ea phenolic bo fa chokolete e lefifi tatso e babang.Ha e bapisoa le chokolete ea lebese la motsoala, e na le mafura a fokolang le tsoekere.Mefuta e lefifi e boetse e theko e boima ho feta mefuta ea lebese ka lebaka la lihlahisoa tse phahameng tsa cocoa, kahoo ho eketsoa ha litšila tse kang matlalo a peanut ho ka fana ka melemo e tšoanang 'me ha e theko e tlaase.Matlalo a matokomane ha se tsona feela litšila tsa lijo tse ka ntlafatsang chokolete ea lebese ka tsela ena.Bafuputsi ba ntse ba hlahloba litsela tsa ho ntša le ho kenyelletsa metsoako ea phenolic ho tloha litšila tsa kofi, tee ea litšila le masala a mang a lijo.
Ho theha chokolete ea lebese e matlafalitsoeng ke antioxidant, Dean le bafuputsi ba Lefapha la Temo la United States (USDA) Agricultural Research Service ba sebelitse le k'hamphani ea peanut ho fumana matlalo a matokomane.Ho tloha moo, ba sila letlalo hore e be phofo ebe ba sebelisa 70% ea ethanol ho ntša metsoako ea phenolic.Lignin le cellulose tse setseng li ka sebelisoa e le lijo tsa liphoofolo bakeng sa roughage.Ba boetse ba sebetsa le baetsi ba kofi ba lehae le bahlahisi ba tee ho sebelisa mekhoa e ts'oanang ho ntša li-antioxidants ho tsoa linthong tsena ho fumana libaka tsa kofi le makhasi a tee.Joale phofshoana ea phenolic e kopantsoe le lijo tse tloaelehileng tsa maltodextrin ho etsa hore ho be bonolo ho kenyelletsa sehlahisoa sa ho qetela sa tsokolate ea lebese.
Ho etsa bonnete ba hore dessert ea bona e ncha e ka fetisa mokete oa lijo, bafuputsi ba thehile chokolete e le 'ngoe ea lisekoere moo mahloriso a phenols a tsoang ho 0.1% ho ea ho 8.1%,' me e mong le e mong o na le kutloisiso e koetlisitsoeng ea ho latsoa.Sepheo ke ho etsa hore phofo ea phenolic ka tatso ea chokolete ea lebese e se ke ea bonahala.Bahlahlobisisi ba tatso ba fumane hore ho ka hlokomeloa ho feta 0.9%, empa ho kenyeletsoa ha phenolic resin ka bongata ba 0.8% ho ka senya maemo a phahameng a ts'ebetso ea likokoana-hloko ntle le ho tela tatso kapa sebopeho.Ha e le hantle, ba fetang halofo ea bahlahlobi ba tatso ba ne ba khetha tsokolate ea lebese la phenolic ea 0.8% ho feta tsokolate ea lebese e sa laoleheng.Sampole ena e na le ts'ebetso e phahameng ea lik'hemik'hale ea antioxidant ho feta lichokolete tse ngata tse lefifi.
Leha liphetho tsena li khothatsa, Dean le sehlopha sa hae sa lipatlisiso le bona ba lumela hore matokomane ke bothata bo boholo ba ho hana lijo.Ba ile ba leka phofshoana ea phenolic e entsoeng ka letlalo bakeng sa boteng ba li-allergenic.Le hoja ho sa fumanoe lintho tse thobang maikutlo, ba ile ba re lihlahisoa tse nang le letlalo la peanut li ntse li lokela ho ngoloa hore li na le matokomane.
Ka mor'a moo, bafuputsi ba rera ho tsoela pele ho hlahloba tšebeliso ea matlalo a peanut, mabaka a kofi le lihlahisoa tse ling tsa litšila bakeng sa lijo tse ling.Haholo-holo, Dean o na le tšepo ea ho hlahloba hore na li-antioxidants letlalong la peanut li ka lelefatsa bophelo ba sethala sa linate, tse ka bola kapele ka lebaka la mafura a tsona a mangata.Leha phepelo ea khoebo ea chokolete ea eona e ntlafalitsoeng e ntse e le hole mme e hloka ho ba le tokelo ea molao ke k'hamphani, ba tšepa hore boiteko ba bona bo tla qetella bo entse hore chokolete ea lebese e lishelefong tsa lisuphamakete e be betere.
