Tag: Polysaccharide identification

Over 50% of the food we consume contains some form of starch, making the iodine test a fundamental scientific procedure. A positive iodine test, used to detect the presence of starch, is identified by a dramatic color change from the original yellowish-brown iodine solution to a deep blue-black.

Polysaccharides, complex carbohydrate polymers like starch and cellulose, are ubiquitous in nature and play crucial roles in living organisms. To determine a polysaccharide in a sample, a variety of analytical techniques, from simple chemical reactions to advanced instrumental methods, are required to reveal its structural and compositional properties.
