Indlela ethokozisayo yokukhiqiza utshwala isanda kumenyezelwa ososayensi baseJapan. Ochwepheshe be-Research Institute of Forestry and Forest Products bakhulume ngeqiniso lokuthi esikhathini esizayo esiseduze bazothokozisa ngotshwala obenziwe ngokhuni.
Iqiniso ngukuthi iziphuzo ezisuselwa ezihlahleni zinokunambitheka okufanayo notshwala obudala emigqonyeni yezinkuni. Lokhu yikho okwenza ochwepheshe bakuhlole ngokujulile ukuncintisana kwalesi siphuzo esisha.
Ulungiselela kanjani? Izinkuni zichotshozwa zibe unamathisela obukhulu, imvubelo nama-enzyme ayengezwa kuwo, inqubo yokuvutshelwa iqala. Ukushoda kokushisa kwesiphuzo (ngokungafani nezindlela zendabuko) kusiza ekugcineni ukunambitheka okuthile kwesihlahla ngasinye.
Okwamanje, ososayensi bakwazile ukudala iziphuzo ezidakayo ngomsedari, i-birch ne-cherry. Ngakho-ke, ngokwesibonelo, u-4 kg wokhuni lomsedari wakwazi ukuthola amalitha we-3,8 wesiphuzo ngokuqukethwe kotshwala okungu-15%, kanti lesi siphuzo sifana kakhulu nentandokazi yaseJapan.
Abathuthukisi balindele ukuthi eminyakeni emithathu ezayo, utshwala "obunamandla" buzovele buvele emashalofini ezitolo. Kulindwe thina.
