鸡皮中功能性极性脂质提取工艺研究

[目的]以鸡皮为原料,探讨鸡皮中功能性极性脂质的最佳提取方法,为今后提取其有效成分,在医药及保健食品的利用开发提供科学理论依据.[方法]Folch法、微波炉加热提取法以及溶剂提取法.[结果]相对于Folch法,微波法虽然可以有效去除中性脂质,但存在以下不足:提取时间短,极性脂质提取不完全；提取时间长,功能性脂质被破坏.溶剂提取法既可以有效去除中性脂质,同时不会引起极性脂质降解,效果最佳,在今后脂质提取实验中可以采用.[结论]对鸡皮功能性极性脂质的提取方法进行分析比较,溶剂提取法效果最佳,在今后脂质提取实验中可以采用.

Studies on Extraction Technology of Functional Polar Lipids in Chicken Skin

[Objective]This study is based on analysis of chicken skin for raw material and studies on extraction technology of functional polar lipids and seeks the best way to extract it,which might provide scientific theory for medical and healthy food fields.[Method]Folch method,extract through microwave and solvent extract methods were used.[Result]Compared with Folch method,although microwave can dissolve the natural lipids,but the result is not very satisfactory.The method takes a short time and it cant extract all polar lipids.If it takes longer time,the function of polar lipids is spoiled.But the solvent extract method can extract natural lipids and meanwhile does not cause degradation of polar lipids.So it can be applied in the future lipid extraction experiments.[Conclusion]Through this experiment,we can compare and analyze the extract technology of functional polar lipids in chicken skin,and the result shows that the solvent extract method achieve the best effect and it can be used in the future experiment.
