英文摘要:

      Objective To explore the optimal technology for extraction of oyster tropomyosin. Methods Taking cultured oyster as raw material, the influences of single factors such as solid-liquid ratio, extraction times, extraction temperature and pH on the extraction rate of tropomyosin from oyster were investigated, and optimized by orthogonal experiment. Results On the basis of pH 5.5, the optimal technological parameters for the extraction of oyster tropomyosin were as follows: The ratio of solid to liquid was 1:2, the extraction times were 6, and the extraction temperature was 100 °C. At this time, the yield of tropomyosin was 6.53%. Conclusion The optimized method in this study has greatly improved the extraction rate of tropomyosin from oyster.
