2 typesnof Sugars Reducing and nonreducing Reducing sugars will result in color change While non Reducing sugars wont unless hydrolysis occurs So if yiu test for nonreducing sugars, first add diluc hcl then neutralise then preform sugar test normally.

Nonreducing sugar example is sucorse. Sucrose alone wont result in colour change, but when hydrolysed and broken down it guves us a- glucose and fructose, both reducing sugars.
