Sucrose is not a reducing sugar since it contains no free aldehyde or keto group adjacent to a  CHOH
group

ducing sugars reduce Fehling's solution and Tollen's reagent. All monosaccharides are reducing sugars. Disaccharides in which aldehydic and ketonic groups are free, behave as reducing sugars.
 
The reducing groups of glucose and fructose are involved in glycosidic bond formation, sucrose is a non-reducing sugar.
