Aqueous solutions of dispersed lycopene in which gum arabic, gum ghatti and polyglycerol monostearate ester had been used as emulsifiers were photoirradiated. The photodegradation rate of lycopene tended to vary depending on the amount of polyglycerol monostearate ester used. We found that the photodegradation rate of lycopene with polyglycerol monostearate ester was considerably slower than those with gum arabic and gum ghatti. Therefore, this study suggests that the absorption state of the emulsifier on the crystal surface may affect the photodegradation rate of lycopene.
