are an acid mass fraction of 3% at a temperature of 130 "C. The
maximum glucose concentration predicted was 85 kg m!3.
This value compare very well with the maximum obtained in
the enzymatic hydrolysis of potato where a maximum of
38.9 kg m!3 was predicted [15]. This can be due to that sulphuric
acid hydrolyzed the resistant starch and the enzymes
used in the enzymatic hydrolysis did not hydrolyze it
