| 中文摘要: |
| 目的 评价岩藻黄素产品在消化系统中的稳定性及变化规律。方法 本文考察了在体外消化模拟状态下岩藻黄素产品中岩藻黄素含量变化, 并采用测定其对DPPH自由基清除能力、铁离子还原能力(ferric ion reducing antioxidant power, FRAP)与氧自由基吸收能力 (oxygen radical absorbance capacity, ORAC)这3种抗氧化指标来评价岩藻黄素产品的抗氧化能力变化。结果 随着人工模拟胃肠消化过程时间的增加, 岩藻黄素产品中岩藻黄素的含量呈下降趋势, 但岩藻黄素微囊粉较岩藻黄素油悬液对岩藻黄素表现出良好的包埋与保护作用。在胃肠消化过程中, 岩藻黄素微囊粉与油悬液对DPPH自由基清除能力、FRAP铁离子还原能力与ORAC氧自由基吸收能力等抗氧化活性指标均有所降低, 其中岩藻黄素微囊粉较油悬液稳定, 表现出较好的抗氧化活性。结论 岩藻黄素微囊粉产品比油悬液产品在消化体系中具有更好的稳定性。 |

| Objective To evaluate the stability and variation of fucoxanthin products in the digestive system. Methods The changes of fucoxanthin content in fucoxanthin products under simulated digestion conditions in vitro were investigated in this paper. The antioxidant activities of fucoxanthin products were evaluated by 3 kinds of antioxidant indexes including DPPH free radical scavenging capacity, ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC). Results The content of fucoxanthin in the products decreased with the increase of simulated gastrointestinal digestion time, but fucoxanthin microcapsule powder showed better embedding and protection effect than fucoxanthin oil suspension. During gastrointestinal digestion, the antioxidant activities of fucoxanthin microcapsule powder and oil suspension, including DPPH free radical scavenging capacity, iron ion reduction capacity and oxygen free radical absorption capacity, were decreased, but fucoxanthin microcapsule powder was more stable than oil suspension, which showed better antioxidant activity. Conclusion Fucoxanthin microcapsule powder product has better stability than oil suspension product in the digestive system. |
