Study on quality properties of prepared beef

  • 摘要: 为了了解目前北京市场上预制牛排质量特征,通过调研,对北京市场上11个品牌6个部位预制牛排进行了主要质量指标的测定,结果表明,不同部位牛排的主要品质指标存在显著或极显著差异,且不同指标间样品的变异幅度也不尽相同;不同品牌及部位牛排的p H、水分、蛋白质含量等品质指标变异度小,CV在10%以内,相对稳定;剪切力、红色深浅(a值)、硬度、脂肪含量等指标差异较大,CV在40%以上,需要今后进一步规范市场质量标准;亮度(L值)、黄色深浅(b值)、弹性等指标变异幅度处于所测指标的中间水平,CV在10%~40%之间;在所测指标中,蛋白质、脂肪含量偏低,剪切力偏高,是我国今后应重点改进的品质指标;当剪切力为2~3kg、水分含量77%、脂肪含量3%以上时,牛排的感官评分最高,适合消费者口感。 
    Abstract: In order to understand the quality properties finished beef sold at Beijing market, a survey was conducted on quality index of finished beef with eleven brands and six parts sampling from Beijing supermarket. The results showed that significant or high significant differences on the major quality index were observed among different brands and parts of beef, and big difference of the variation extent among the measured index were also found.The index value of p H, water and protein content of beef were relatively stable, CV < 10%. Big differences were observed in the index of shearing force, red shade ( a) , hardness and fat content of beef among the measured samples, CV > 40%. It is necessary to formulate the quality standards for the four index. The variation extents of brightness ( L) , yellow shade and elasticity were found at middle level with CV of 10% 40% among the measured samples.Among the all measured index, protein and fat content were a little bit low and shearing force was higher, and the three index were considered to be the prefer quality index of beef and should be implemented preferentially.The taste score of steak was highest for consumers when the shear force, moisture content and fat content reached 2 3kg, 77% and 3% or more, respectively.
