Is there a test one can do?

Yes, you are testing for reducing sugars.
Good luck!

hi,
glucose is a reducing sugar monosaccharide and sucrose is a disaccharide consist of a molecule of glucose (a reducing sugar) binding to a molecule of fructose (a non-reducing sugar). so, here you have 2 ways for determine the sucrose.
the first one, if you only have reagents for detecting the reducing sugar then you have first to detect the glucose in the mix and then you treat the mix with an enzyme to hydrolyze sucrose to glucose and fructose such as ( invertase or fructosidase) and then determine the reducing sugars again here reading 2 - reading one = sucrose determination (the reading represent sucrose because the ratio between sucrose and fructose in sucrose molecule is 1:1.
the second method u can either use paper chromatography methods, http://pubs.acs.org/cgi-bin/abstract.cgi/ancham/1957/29/i01/f-pdf/f_ac60121a008.pdf?sessid=2395
or the use the polarimeter (Saccharimeter) method which need an spacial equipment.

its a smaller molecule of sugar so how would u know if its different unless u have an elextron microscope
thats the only way
