摘要:采用不同功率的超声波(0、250、500和750 W) 分别辅助腌制处理牛霖1h和2h后,测定牛肉中加压损失、水分含量、蒸煮损失、剪切力和氯化钠含量。结果表明,增大超声波功率及延长处理时间能够显著降低牛肉的加压损失、蒸煮损失和剪切力,同时显著提高牛肉中的水分含量和氯化钠含量。因而超声波辅助腌制处理可有效地提高腌制牛肉的品质,缩短牛肉腌制处理时间,从而有利于提高牛肉加工产品的质量。28604 毕业论文关键词:腌制; 超声波; 牛肉; 品质
Influence of Ultrasound Treatment on the Quality Characteristic of Salted Beef
Abstract:The pressure loss, moisture content, cooking loss, shear stress and sodium chloride content in beef topside were measured after ultrasonic curing treatment with different power (0, 250, 500 and 750 W) for 1 h and 2 h respectively. The results showed that increasing the ultrasonic power and treatment time could reduce the pressure loss, cooking loss and the shearing force of beef. In addition, the moisture content and the sodium chloride content in the beef could also be increased by ultrasound treatment. Therefore, ultrasonic assisted curing can significantly improve the quality of beef and shorten the processing time. Meanwhile this technology could improve the quality of beef product.
