Amylose azure is a dye commonly used to detect and measure α-amylase activity in various applications. This dye is particularly useful in assessing the hydrolysis of starch by α-amylase. Amylose azure reacts with the enzyme and produces a blue color that can be quantified using spectrophotometry. In addition to its analytical applications, amylose azure is also used as a visual indicator of the presence of aluminum. The dye forms a complex with aluminum ions, resulting in a distinct color change that can be easily observed.
