| Abstract: |
| In order to make full use of the byproducts of shrimp processing, the optimal process and influencing factors of extraction phospholipids from shrimp head were studied by solvent extraction method. The effects of ratio of material to solvent, volume fraction of ethanol, extraction time and extraction times on the extraction of phospholipids were researched by single factor experiment and orthogonal experiment with phospholipids purity as index to obtain the optimal extraction process of phospholipids from shrimp head. The results showed that the optimal extraction conditions of phospholipids from shrimp head were obtained as follows: ratio of material to solvent 1∶?6, volume fraction of ethanol 90%, extraction time 6 h and extraction twice. Under these conditions, the phospholipids purity in shrimp head extract was 4581%. The process had advantages of simple, less pollution and high extraction efficiency, which provided an effective way for the high value utilization of low-value-added seafood byproducts. |
