Iindaba ezimnandi zabathandi betshokolethi-izazinzulu zisenokuba ziyifumene indlela yokwenza iilekese zibe sempilweni.
Ukusela itshokolethi emnyama ngokumodareyitha kudala kudunyiswa ngenxa yeempawu zayo ze-antioxidant, kodwa ayinguye wonke umntu onokuqala ngobukrakra bayo obuninzi.
Iqela lophando elivela kwi-American Chemical Society (ACS) lifumene ukuba ukongeza isikhumba somgubo wepeanut kwitshokolethi yobisi kunokwenza i-indulgences ibe yi-antioxidants ngaphezu kweentlobo ezimnyama ngaphandle kokuphazamisa i-creamy okanye ukukhanya kwayo.
Xa kunikwa iqela labavavanyi incasa, ngaphezu kwesiqingatha bade bakhetha itshokolethi yobisi ekhutshiweyo ngamandongomane kunezo zithengwe ezivenkileni namhlanje.
Umbhali wokuqala uGqr. Lisa Dean wathi: "Umbono weprojekthi uqale ngokuvavanya imisebenzi yebhayoloji yeentlobo ezahlukeneyo zenkunkuma yezolimo, ngakumbi izikhumba zamandongomane."
"Injongo yethu yokuqala yayikukukhupha i-phenols (iklasi yeekhemikhali ezineepropathi ze-antioxidant) esikhumbeni kwaye sifumane indlela yokuyixuba nokutya."
Xa amandongomane eqhotyiswa kwibhotolo yamandongomane okanye kwiconfectionery, uqweqwe lwawo lwephepha elibomvu luyalahlwa, nto leyo ephumela kwinkunkuma engamawaka eitoni minyaka le.
Oku kushiya i-lignin kunye ne-cellulose (izinto ezimbini kwiindonga zeeseli zezityalo), ezinyusa umthamo we-roughage ekutyeni kwezilwanyana.
I-powder ephumela ke ixutywe kunye ne-maltodextrin (i-additive food additive) ukuze kube lula ukuyifaka kwi-tshokoleta yobisi.
UGqr. Dean wathi: “I-phenolic resin ikrakra kakhulu, ngoko kufuneka sifumane indlela yokuphelisa le mvakalelo.”
Xa isetyenziswe ngabavavanyi bokungcamla, iqela lifumanise ukuba liyakwazi ukubona ukugxininiswa okungaphezulu kwe-0.9%, okuchaphazela incasa okanye ukuthungwa.
Iziphumo ezithiwe thaca kwinkomfa ye-ACS 2020 kunye nomboniso zibonisa ukuba ngaphezulu kwesiqingatha sabavavanyi bencasa bade bakhethe i-0.8% yetshokholethi yobisi ye-phenol kunohlobo oluqhelekileyo, kwaye umsebenzi we-antioxidant wale sampuli uphezulu kuneyetshokholethi ezininzi ezimnyama.
Abantu abakhetha itshokholethi emnyama ngezibonelelo zempilo banokuqaphela ukuba itshokholethi emnyama ibiza kakhulu kuneentlobo zobisi ngenxa yomxholo wayo ophezulu wecocoa.
Iingcali zenzululwazi zikholelwa ukuba ukongeza isikhumba se-peanut kwi-tshokoleta yobisi kunokuphucula impilo ngexabiso elifanayo.
Bavuma umngcipheko we-allergies, kodwa nayiphi na itshokholethi etyebileyo kwi-peanuts kufuneka ibhalwe njengequlethe izinto eziqhelekileyo.
Ukunciphisa le nkxalabo, izazinzulu ziceba ukuvavanya amabala ekofu kunye nenye inkunkuma ngendlela efanayo.
Banethemba lokufumanisa ukuba i-antioxidants kwizikhumba ze-peanut inokwandisa ubomi beshelufu ye-nut butters, eya kubola ngokukhawuleza ngenxa yezinto ezinamafutha aphezulu.
