摘  要：
为探究不同温度烘烤下坛紫菜的消化情况,本试验通过构建体外消化模型,对不同消化过程中坛紫菜的细胞形态进行观察并测定其营养物质含量和抗氧化活性,分析不同温度烘烤后坛紫菜在消化过程中的变化规律。结果表明,不同温度烘烤的坛紫菜经口胃肠连续消化后,细胞裂解有差异,其中180℃和200℃处理组的坛紫菜细胞裂解程度大。体外消化结果表明,坛紫菜的游离氨基酸含量释放主要集中在胃肠道中,可溶性糖及还原糖主要集中在胃消化过程中,抗氧化活性在胃消化过程中表现最强,其中180℃烘烤坛紫菜的营养物质释放量和抗氧化活性最佳,200℃处理组次之。本研究结果为提高坛紫菜的生物利用率以及评价其不同加工模式提供了一定的理论依据。

摘  要：
The in vitro digestion model was constructed for exploring the digestion of Pyropia haitanensis prepared at different baking temperatures, the cell morphology was observed, the nutrient content and antioxidant activity were analyzed during the whole digestion, to obtain the relative results about P.haitanensis prepared at different temperature during the digestion process. The results showed the situation of P.haitanensis cell disruption was differential after digestion by the gastrointestinal tissue, the samples baked at 180℃ and 200℃ were higher than others. The in vitro digestion results illustrated free amino acids of it release was mainly occurred in the gastrointestinal process, soluble sugars and reducing sugars release were major in gastric process, and the antioxidant activity was obtained in the gastric digestion. Nutrient release and antioxidant activity were reached to maximum when it was baked at 180℃, following by the sample dealt by 200℃ condition. These results proved that baking at 180℃ was the best for digestion and absorption in gastrointestinal organization of Pyropia haitanensis. This research provides certain theoretical bases for improving P. haitanensis bioavailability and the evaluation of different processing conditions.
