Tag: Polysaccharide detection

According to biochemical research, the iodine test is the classic and most well-known method for detecting the presence of polysaccharides like starch. This simple colorimetric reaction relies on iodine-potassium iodide, commonly known as Lugol's solution, to produce a dramatic color change in the presence of certain complex carbohydrates. However, other reagents are also used depending on the specific type of carbohydrate and the analysis required.

The Iodine test is a standard biochemical method, and studies show it is highly effective for determining if large polymer molecules are present. This qualitative analysis is a foundational technique in biology and chemistry to identify polysaccharides in a sample.
