Abstract
Disclosed herein are photoisomerized compositions comprising anthocyanins and methods of making an use thereof. For example, disclosed herein are methods of photoisomerizing a composition, the methods comprising: irradiating a composition comprising an anthocyanin dissolved in a solvent solution with UV light; wherein at least a portion of the anthocyanin is present as a trans isomer before the irradiation; wherein the solvent solution comprises ethanol and water in a ratio of ethanol to water (volume/volume) of 99:1 to 70:30; thereby converting at least a portion of trans isomer to a cis isomer via photoisomerization to produce a photoisomerized composition. In some examples, the photoisomerized composition has a more intense and stable blue color at pH 8 relative to the composition before irradiation.
