Izindaba ezinhle zabathandi bakashokoledi-ososayensi kungenzeka bathole indlela yokwenza amaswidi abe nempilo.
Ukuphuza ushokoledi omnyama ngokulinganisela sekuyisikhathi eside kudunyiswa ngenxa yezakhiwo zawo ze-antioxidant, kodwa akuwona wonke umuntu ongaqala ngokubaba kwawo okucebile.
Ithimba labacwaningi abavela ku-American Chemical Society (ACS) lithole ukuthi ukwengeza isikhumba sikafulawa wamantongomane kushokoledi wobisi kungenza i-indugences ibe ama-antioxidants amaningi kunezinhlobo ezimnyama ngaphandle kokuphazamisa ukuthungwa kwayo okukhilimu noma ukukhanya.
Uma unikezwa iqembu labahloli bokunambitheka, abangaphezu kwengxenye baze bancamela ushokoledi wobisi olunesikhumba samantongomane kunalowo othengwa ezitolo namuhla.
Umbhali wokuqala uDkt. Lisa Dean wathi: “Umqondo wale phrojekthi waqala ngokuhlola umsebenzi webhayoloji wezinhlobo ezahlukene zemfucuza yezolimo, ikakhulukazi izikhumba zamakinati.”
“Umgomo wethu wokuqala kwakuwukukhipha ama-phenols (ikilasi lamakhemikhali anezakhiwo ezilwa ne-antioxidant) esikhumbeni futhi sithole indlela yokuwaxuba nokudla.”
Lapho amantongomane ethoswa abe yibhotela lamantongomane noma isiphuzo, uqweqwe lwawo lwephepha olubomvu luyalahlwa, okuphumela ezinkulungwaneni zamathani emfucumfucu minyaka yonke.
Lokhu kushiya i-lignin ne-cellulose (izinto ezimbili ezindongeni zamaseli ezitshalo), okwandisa okuqukethwe kwe-roughage ekudleni kwezilwane.
Impushana ewumphumela bese ixutshwa ne-maltodextrin (isithako esivamile sokudla) ukuze kube lula ukuhlanganisa ushokoledi wobisi.
UDkt. Dean wathi: “I-Phenolic resin iyababa kakhulu, ngakho kufanele sithole indlela yokudambisa lo muzwa.”
Uma isetshenziswa abahloli bokunambitheka, ithimba lithole ukuthi lingathola ukugxila okungaphezu kuka-0.9%, okuthinte ukunambitheka noma ukuthungwa.
Imiphumela eyethulwe engqungqutheleni nasembukisweni we-ACS 2020 ikhombisa ukuthi abahloli bokunambitheka abangaphezu kwengxenye baze bancamele ushokoledi wobisi we-phenol ongu-0.8% kunezinhlobonhlobo ezijwayelekile, futhi umsebenzi wokulwa ne-antioxidant waleli sampula uphakeme kunowoshokholethi abaningi abamnyama.
Abantu abakhetha ushokoledi omnyama ngezinzuzo zezempilo bangase futhi baqaphele ukuthi ushokoledi omnyama ubiza kakhulu kunezinhlobo zobisi ngenxa yokuqukethwe kwawo okuphezulu kwe-cocoa.
Ososayensi bakholelwa ukuthi ukwengeza isikhumba samantongomane kushokoledi wobisi kungathuthukisa impilo ngezindleko ezifanayo.
Bayabuvuma ubungozi bokungezwani komzimba nezinto ezithile, kodwa noma yimuphi ushokoledi ocebile ngamakinati kufanele ubhalwe ukuthi uqukethe izinto ezingezwani nomzimba ezivamile.
Ukuze banciphise lokhu kukhathazeka, ososayensi bahlela ukuhlola izindawo zekhofi nokunye udoti ngendlela efanayo.
Banethemba lokuthola nokuthi ama-antioxidants esikhumbeni samantongomane angakwazi yini ukunweba impilo yeshalofu yamabhotela amantongomane, azobola ngokushesha ngenxa yokuqukethwe kwawo kwamafutha amaningi.
