Abstract:

Objective: To explore the effect of emulsification on the bio-accessibility of natural lycopene in male rats. Methods: Totally 30 SD male rats with body weight of 250 g were randomly divided into 3 groups for 10 in each group. The rats were administered emulsified natural lycopene solutions with final lycopene concentrations of 0.263, 0.525 mg/mL and 1.575 mg/mL, respectively once a day for 4 consecutive days. The amount of lycopene in feces collected within 24 h after each administration was determined and the bio-accessibility of natural lycopene was calculated. Results: The bio-accessibilities of emulsified and unemulsified lycopene reached their separate maximum values on the 3th day of administration; increasing administration amount resulted in a lower bio-accessibility of emulsified and un-emulsified lycopene. Conclusion: Emulsification is able to increase the bio-accessibility of natural lycopene.

Key words: lycopene, absorption, emulsification
