摘要:

为解决河蚌肉的肉质粗韧问题,提高其食用品质,利用超声波辅助木瓜蛋白酶对其嫩化处理。通过Box-Behnken试验设计,建立了综合评分与超声功率、超声时间、木瓜蛋白酶质量分数之间的二次回归模型;确定超声波辅助木瓜蛋白酶嫩化河蚌肉的最佳工艺参数为木瓜蛋白酶质量分数6%、超声功率150 W、超声时间27 min,此时河蚌肉嫩化效果最佳。与木瓜蛋白酶、超声波、CaCl2嫩化效果相比,可溶性蛋白含量提高48%,硬度和咀嚼性分别降低63%和65%。

Abstract:

In order to improve the taste of freshwater mussel meat, tenderization was carried out by ultrasound-assisted
papain treatment. Using Box-Behnken experimental design, a quadratic regression model was developed indicating the effect
of ultrasonic power, ultrasonication time, and enzyme concentration on tenderization efficiency. Through response surface
analysis of the established model, the optimal parameters that provide the best tenderness of mussel meat were determined
as 6%, 150 W and 27 min for enzyme concentration, ultrasonic power and ultrasonication time, respectively. Compared with
individual treatment with papain, ultrasound and CaCl2, the combined treatment resulted in a 48% increase in soluble protein
content of mussel meat, with a simultaneous decrease in hardness and chewiness by 63% and 65%, respectively.

Key words: freshwater mussel, tenderness, ultrasound-assisted treatment, papain
