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.

Scientific research shows that soluble sugars play a critical role as signaling molecules and osmoprotectants in plants under stress. This guide will detail how to calculate total soluble sugars, covering the precise, lab-based Anthrone method and the rapid, field-friendly refractometry technique for accurate measurements in various samples.
