Nanoemulsions with 尾-carotene in soybean oil were prepared with WPI and lecithin.
Addition of eugenol in oil improved the storage stability of nanoemulsion droplets.
Addition of eugenol in oil improved the storage and UV stability of 尾-carotene.
Addition of eugenol in oil reduced thermal degradation of 尾-carotene.
Reduction of free radicals by endogenous eugenol improved the stability of 尾-carotene.
