测定猪肉糜二次杀菌前后的蒸煮损失、质构特性以及自旋-自旋弛豫时间,研究85℃条件下二次杀菌时间(0、5、10、15、20、25 min)对猪肉糜持水性的影响。结果表明:二次杀菌导致蒸煮损失率显著增加(P<0.05),当杀菌时间超过15 min时,质构特性参数值显著降低(P<0.05),不易流动水相对含量显著(P<0.05)降低,而自由水相对含量则显著(P<0.05)升高。说明二次杀菌时间会影响肉糜中蛋白质的保油保水性,进而影响肉糜制品的质构特性。
測定豬肉糜二次殺菌前後的蒸煮損失、質構特性以及自鏇-自鏇弛豫時間,研究85℃條件下二次殺菌時間(0、5、10、15、20、25 min)對豬肉糜持水性的影響。結果錶明:二次殺菌導緻蒸煮損失率顯著增加(P<0.05),噹殺菌時間超過15 min時,質構特性參數值顯著降低(P<0.05),不易流動水相對含量顯著(P<0.05)降低,而自由水相對含量則顯著(P<0.05)升高。說明二次殺菌時間會影響肉糜中蛋白質的保油保水性,進而影響肉糜製品的質構特性。

The effect of secondary sterilization time (0, 5, 10, 15, 20 and 25 min at 85℃) on the water-holding capacity of pork meat batters was investigated by measuring the cooking loss, texture properties and spin-spin relaxation time. The minced pork was kept in a thermostatically controlled water bath maintained at 75℃ for 20 min and then at 85℃for different lengths of time. Results indicated that the secondary heating led to a significant increase in cooking loss (P<0.05), a significant reduction in texture properties when the heating time exceeded 15 min and in the relative amount of immobilized water (P<0.05), and a significant increase in the relative amount of free water (P<0.05). Therefore we concluded that secondary sterilization time can affect the water and oil holding capacities of minced meat products, thus influencing their texture properties.
