Dry potato peel waste (PPW) composition is given in Table 1.
Soluble sugar, reducing sugar and starch are part of total carbohydrates.
Lignin was not estimated. As shown, potato peel waste
(PPW) had a high starch content (52% d.w.) but the fermentable
reducing sugar was very low (0.6% d.w.). For this reason, any fermentation of the raw material is not practical and an initial
hydrolysis (acidic or enzymatic) of carbohydrates is necessary.
