Hydrolysis opens up the rings and allows oxidation of fructose, Glucose is already reducing sugar, and therefore, honey after hydrolysis is a reducing sugar and can be thus utilized, by the organisms which do not contain invertase.
Starch do not oxidize and its chemical formula is stable. The rings of starch are not able to open and are required to be hydrolysed in order to open these rings.
