凡纳滨对虾肌肉盐溶蛋白提取工艺研究

Study on the Extraction Technology of Salt-soluble Protein in Penaeus Vannamei Muscle

摘要:

本实验以凡纳滨对虾肌肉为原料，盐溶蛋白得率为指标，研究盐溶蛋白最佳提取工艺参数，得到其最佳提取条件：NaCl浓度0.6 mol/L；抽提时间25 h；料液比1:4；pH值7。此条件下盐溶蛋白含量为105.73 mg/g，提取率为83.34%。

Abstract:

The extraction process parameters of salt-soluble protein were studied with the muscle of Penaeus Vannamei as raw materials and the salt- soluble protein yield as an indicator in this experiment. The optimized extraction conditions were determined as follows:NaCl 0.6 mol/L, extraction time 25 h, solid-liquid ratio 1:4, and pH 7. Under these conditions, the salt-soluble protein content was 105.73 mg/g and yield was 83.34%.
