条斑紫菜多糖与薏米仁多糖复配物的制备及其降血脂功效研究

Preparation and Antihyperlipidemic Effect of Porphyra Yezoensis Polysaccharides and Glutinous Rice Kernel Polysaccharides

  • 摘要: 本文通过对粗粮的筛选,选出最佳粗粮与浡海条斑紫菜进行复配,对其进行吸油量及脂肪酶等降血脂功能性指标的测定进行研究,首先响应面法优化条斑紫菜可溶性多糖的最佳超声波法提取工艺,再在9种粗粮中筛选出最适复配的粗粮种类,再以体外油脂吸附能力即吸油量为指标,筛选出条斑紫菜多糖和粗粮多糖的最佳复配比,最后使用复配物对小鼠脂肪酶进行抑制活性实验。结果表明:超声波法最佳提取条斑紫菜多糖的工艺为:料液比1:25,超声功率为150 W,超声温度60 ℃,超声时间30 min,获得水溶性多糖得率为4.24%±0.19%。筛选9种粗粮中得到薏仁米最适合与条斑紫菜多糖复配,且最佳复配比为1:1,吸油量最大为45.87%±5.27%,对小鼠脂肪酶抑制率为34.67%。本实验为研发新型渤海紫菜降血脂功能性食品提供理论依据。

     

    Abstract: The best coarse grain for compounding with Porphyra yezoensis was selected through the screening of coarse grains for the research about measurement of hypolipidemic functional indexes such as oil absorption and lipase.Firstly,Response Surface Methodology was used to optimize the extraction process of soluble polysaccharides from Porphyra yezoensis by ultrasonic wave. Secondly,the best kind was selected from nine different kinds of coarse grains. Thirdly,the oil absorption capacity in vitro was noticed as the index to screen out the optimum compound ratio of Porphyra yezoensis polysaccharide and coarse grains polysaccharide. Finally,the inhibitory activity of mouse lipase was tested using a compound. The results showed that the optimum extraction technology of Porphyra yezoensis polysaccharides by ultrasonic method was as follows:Material-liquid ratio 1:25,ultrasonic power 150 W,ultrasonic temperature 60 ℃,ultrasonic time 30 min,and the extraction rate of water-soluble polysaccharides was 4.24%±0.19%. Among 9 kinds of coarse grains,coix seed was the most suitable for compounding with Porphyra yezoensis polysaccharide,and the optimum ratio was 1:1.The maximum oil absorption was 45.87%±5.27%. The inhibition rate to mouse lipase was 34.67%. This study provided experimental basis for the development of a new type functional food for reducing blood lipid of Porphyra yezoensis in Bohai Sea.
