Anthocyanins are the most prominent group of water-soluble pigments in nature, responsible for the vibrant red, purple, and blue hues seen in many fruits, vegetables, and cereals. These pigments are stored in cell vacuoles and are easily visible to the human eye.

BQC Anthocyanins Assay Kit, is an easy, fast and reliable method for detecting anthocyanins. Utilizing the pH differential technique, this assay measures total monomeric anthocyanin content by observing their color transformation at two distinct pH levels. The BQC Anthocyanins Assay Kit determine the anthocyanin concentration by measuring the absorbance at 510 nm after sample acidification. Turbidity (haze) is corrected by measuring the absorbance at 700 nm.
