冷藏时间对冷却猪肉糜凝胶特性的影响

Effect of the Different Cold Storage Time on Gel Properties of Chilled Pork Batters

  • 摘要: 本文以托盘包装的冷却猪背最长肌为原料,在4 ℃条件下避光贮藏0、1、3、5和7 d后,分别加工成猪肉糜,分析猪肉糜pH、色差、蒸煮得率、质构和流变性的变化,研究不同冷藏时间对猪肉糜凝胶特性的影响。结果表明:随着冷藏时间的延长,猪肉糜的色差、蒸煮得率和质构呈下降趋势(p<0.05),说明猪肉糜凝胶性能变差。其中L*值和蒸煮得率在冷藏0、1和3 d时,差异不显著(p>0.05)。流变结果表明,在72 ℃时,0、1 d和3 d的G'差异不显著,超过72 ℃后,G'在0和1 d时最大。综上,猪肉糜在冷藏3 d前进行加工,能够保持其良好的凝胶性能。

     

    Abstract: In this paper, the longissimus dorsi of chilled pork with pallet packaging as raw material, was storage away from light 0, 1, 3, 5, and 7 d at 4℃, then been made into pork batters. The changes of pH, color, cooking yield, texture and rheological properties of pork batters were analyzed, and the effect of the different cold storage times on the gel characteristics were studied. The results showed that the pH, color, cooking yield and texture of pork batters were significantly decreased (p<0.05), and the L* values and cooking yield were not significantly different (p>0.05) between 0, 1 and 3 d, that indicated the gel characteristics of pork batters were decreased with storage time increasing. The rheological results were found that the G' of 0, 1 and 3 d were not significantly different (p>0.05) at 72℃, and the G' of 0 and 1 d was the biggest over 72℃. To sum up, the pork batters had better gel properties before cold storage 3 d at 4℃.
