Sucrose and water are mixed in E-flasks in ratio liquid:solid 10:1. Temperature is kept constant at 60° C. in an oven equipped with a shake table. Succinic acid is added to the flasks to give concentrations of 1, 3, and 5% acid by weight. The data is shown in Tables 5 to 7. An increase in the catalyst loading increases the rate of hydrolysis significantly at low temperatures. Yields after ten (10) hours hydrolysis for glucose and fructose are summarized in Table 1. The yields are based on the amount of glucose or fructose formed divided by the amount of sucrose hydrolyzed. For glucose at higher acid concentrations some product degradation takes place. For fructose some degradation is evident at all acid concentrations.

Hydrolysis of Liquid:To produce a media with high enough sugar concentration for fermentation purposes higher liquid:solid ratios (higher percentages of sucrose) must be used. Using the same experimental setup as in Example 2, but with liquid:solid ratio 10:4, acid concentrations of 1%, and 5% were investigated at 80° C. and 100° C. Sucrose hydrolysis results are presented in Table 14. Yields after finished hydrolysis are shown in Table 2. The yields are expressed on a weight basis as the mass of produced monosaccharides per mass of hydrolyzed sucrose. From the yields it can be seen that the best results are achieved by low acid loadings and high temperatures. After one hour the yields were close to 100%, and heating for another hour did not generate any significant sugar degradation.
