摘要:

采用乳化与未乳化的天然番茄红素萃取物配制成番茄红素含量为0.263mg/mL(低剂量)、0.525mg/mL(中剂量)和1.575mg/mL(高剂量)的灌胃液。选用250g SD 雄性大鼠30 只分成3 组,每组10 只,每天一次灌胃1mL,收集大鼠24h 内的粪便。测定粪便中的番茄红素含量,计算番茄红素的生物接近度。乳化与未乳化物在大鼠体内的生物接近度于第3 天达到最大值;饲喂剂量增加可以降低乳化物与未乳化物的生物接近度;乳化可以提高番茄红素的生物接近度。

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
