Why does the Benedict solution change colours when heated with glucose?
sugars are converted to enediols by benedict's reagent on boiling. these enediols reduce Cu(II) to Cu(I) which then forms CuOH (yellow in color). on heating CuOH yields Cu2O which is orange/red in color.

Benedict's solution tests for aldehyde which is present in reducing sugars. If the solution remained blue than no reducing sugar's are present in corn oil.
What is the color of a solution when starch is added?
Benedicts tests for the presence of monosaccharides. It will turn a yellow to red color if it is a positive test, but it does not so starch does not contain monosaccharides. ...Actually..... If starch is heated at 250 degrees Celsius, it breaks down into sugar! a saccharide! The intense heat denatures the the starch and transforms it into sugar. Also, if you have starch and amylase ( enzyme found in your saliva) and heat that to 37 degrees Celsius, you will also get a sugar, but in the form of glucose!
