Preview (Summary results of the experiment showed that after chewing rice slurry then drops Benedict and the boiling water. Brown will take up When monitoring solution with Benedict. To precipitate a red brick Shows that saliva contains enzymes that help digest starch. Changes occurring sugars from starch using enzymes in saliva only. The process makes it smaller so-called digestion.
