while its application in rootor tuber mash prepared from dicotyledonous plants is still limited.This is mainly due to the highly viscous nature of root and tubermashes caused by their high pectin content, which leads to entrap-ment of water in the cell wall matrix [11]. This results in difficultiesin mixing and solid–liquid separation leading to incomplete hydrol-ysis of starch to sugar, which reduces the overall fermentationefficiency [12,13].
