中文摘要:
      目的 研究玉米淀粉-壳聚糖可食膜对兔肉在冷藏期间品质特性的影响。方法 测定玉米淀粉-壳聚糖可食膜的物理特性, 并研究包膜处理对 (4±1)℃冷藏兔肉的pH值、 剪切力、 硬度、 挥发性盐基氮 (TVB-N)、 硫代巴比妥酸值 (TBA)、 高铁肌红蛋白含量 (MetMb) 和菌落总数等指标的影响。结果 玉米淀粉-壳聚糖可食膜的抗拉强度为(13.82±0.46)MPa, 伸长率为(28.08±0.23) %, 水蒸气透过率为(1.24±0.03) ×10-10 g/ (m·s·Pa)。玉米淀粉-壳聚糖可食膜可使兔肉冷藏过程中的剪切力和硬度减缓下降, 在贮藏中后期显著延缓兔肉pH, TVB-N, TBA, MetMb值的上升(P<0.05), 明显抑制兔肉表面微生物菌落总数的增加。结论 玉米淀粉-壳聚糖可食膜可有效减缓生鲜兔肉在冷藏过程中的品质劣变, 具有良好的保鲜效果。
英文摘要:
      The objective of this study was to investigate the effects of corn starch-chitosan films coating on rabbit meat quality after cold storage. The physical characteristics of corn starch-chitosan were investigated before coating rabbit meat. The pH, shearing force, hardness, TVB-N, TBA, MetMb and total bacterial colony of rabbit meat with/without coating were measured during(4±1) ℃ storage. Our results showed that tensile strength, elongation and WVP of starch-chitosan films were (13.82±0.46) MPa, (28.08±0.23) %, and (1.24±0.03)×10-10 g/ (m·s·Pa) . The shear force and hardness were slowed down after coating of corn starch-chitosan films. In addition, the corn starch-chitosan films significantly delayed the rising of pH, TVB-N, TBA, MetMb (P<0.05) and effectively restrained the growth of surface microorganisms. Taken together, corn starch-chitosan films had good preservation effects for fresh rabbit meat storage.
