Sugars Production from Endocarps of Olive Fruit by Dilute Sulphuric Acid Hydrolysis and Enzymatic Hydrolysis

M. Cuevas, S. Sánchez, M. Saleh & J.F. García
Olive stones (OS) have high carbohydrates content and could be a suitable material for sugars production by two-steps hydrolysis process: with inorganic acids followed by enzymatic hydrolysis of the remained solids. Firstly, pretreatment of OS by dilute sulphuric acid, at high temperatures (190ºC–215ºC) and a high solid/liquid ratio (1/3), was investigated in this study. Olive stones in fragments were used with their original sizes. D-xylose was the major sugar in the prehydrolysates, with a maximum...
