Abstract

The quality and protein digestibility of chicken gizzards influenced by ultrasound pretreatment and stir-frying time were investigated. The results indicated that with the extension of stir-frying time, the yield, springiness, tenderness and protein digestibility of samples significantly decreased (P < 0.05), while they increased after ultrasound pretreatment. When the stir-frying time was 5 min, the shear force of samples treated with ultrasound decreased by 25.4% and the protein digestibility increased by 65.3% and 34.7% compared with the non-ultrasound. Additionally, the samples stir-fried for 5 min after ultrasound pretreatment (U-5) had the highest overall acceptance score and best flavor. Hierarchical cluster analysis was applied to all the obtained data, which described the main characteristics of stir-frying chicken gizzard samples from different treatment groups. In conclusion, ultrasound pretreatment is an effective method to improve the quality and promote protein digestion of stir-frying chicken gizzards.

超声预处理提高鸡胗品质及蛋白质消化率的研究

研究了超声预处理和炒制时间对鸡胗品质和蛋白质消化率的影响。结果表明，随着翻炒时间的延长，样品的产率、弹性、嫩度和蛋白质消化率显著降低(P <p < 0.05)，超声预处理后升高。当搅拌时间为5 min时，超声处理的样品剪切力比未超声处理的样品降低了25.4%，蛋白质消化率分别提高了65.3%和34.7%。超声预处理(U-5)后炒5min的样品总体接受度最高，风味最佳。对所得数据进行聚类分析，描述了不同处理组的鸡胗样品的主要特征。综上所述，超声预处理是提高鸡胗品质和促进蛋白质消化的有效方法。
