重组鹿肉制品的加工特性

    Processing property of recombinant product made of venison and pork

    • 摘要: 该文以不同营养、风味和加工特性的鹿肉和猪肉为原料,加非肉蛋白等营养强化物质,借谷氨酰胺转胺酶(TG)的粘合交联作用研制营养风味俱佳的重组鹿肉制品。单因素试验得出各因素对重组特性(剪切力、拉伸强度和蒸煮损失)的影响:TG-B(含1%TG、99%蛋白质)作用效果优于TG-A(含0.5%TG、99.5%蛋白质);大豆蛋白对重组特性和品质的作用效果优于脱脂麦胚蛋白、乳清蛋白、酪蛋白酸钠等非肉蛋白;TG-B的作用温度和时间、食盐和复合磷酸盐对嫩度和持水性的影响显著。借因子分析法和Plackett-Burman(PB)设计筛选出影响肉制品重组效果的主要因素为TG-B作用温度、食盐和大豆蛋白;运用中心组合设计和响应曲面分析优化出重组肉制品的最佳工艺参数为TG-B 0.5%、复合磷酸盐0.4%、食盐2%、大豆蛋白4.1%、42℃反应30 min、80℃灭酶20 min。

       

      Abstract: Nutritious and delicious recombinant meat product in which the venison and pork were taken as material, non-meat proteins were added was prepared through the binding action of transglutaminase. The influence of factors on shearing strength, tensile strength and cooking loss of recombinant meat product was studied by single-factor tests. It is found that the influence of TG-B (1% TG, 99% protein) on recombinant properties is better than that of TG-A and soybean protein is superior to the non-meat protein, such as degrease wheat embryo protein, whey protein and sodium butyric. The influence of TG-B reaction temperature, reaction time, salt and compound phosphate on tenderness and water holding capacity of recombinant product are significant. The factors of recombination effect were filtrated by the method of factor analysis and Plackett-Burman designed experiment and the primary factors are TG-B reaction temperature and time, salt and soybean protein. The optimal processing parameters obtained by central composite design and response surface methodology were as follows: TG-B 0.5%, compound phosphate 0.4%, salt 2%, soybean protein 4.1%, reaction in 42℃ for 30 min, enzyme inaction in 80℃ for 20 min.
