Application

Erythrosin B belongs to the class of xanthene dyes, which can find applications as a food colorant.(12} It can exhibit light absorption in the range of 500-550 nm, hence can lead to the formation of reactive oxygen species, which can inactivate the microorganisms, thereby acting like an antimicrobial agent.
