Abstract:
An unknown color in chewing gum imported from Canada was determined. The color was identified by TLC and HPLC as the trisodium salt of 3-hydroxy-4[(4-sulfopheny)azo]-2,7-naphthalenedisulfonic acid (RS-SA), one of the subsidiary colors of sunset yellow FCF. The concentration of RS-SA in sunset yellow FCF used in the chewing gum was 4.3%
