Pre-Lab: Starch and Glucose Identification
Purpose
The purpose of this lab is to detect both Glucose (monosaccharide) and Starch (polysaccharide) in common foods.
Glucose will be identified by testing with Benedict's solution and Starch will be identified by testing with Iodine solution
Step 1: Watch the following video on the Benedict's test for the identification of Glucose. (Video Credit: Michelle Sanders - Limonthas)
