摘　　要：为探究磁场辅助对调理肉冷冻、解冻及其耦合处理的作用效果,以生鲜调理肉饼为实验原料,分析不同强度(1.5 mT和4.5 mT)的静磁场和交变磁场处理对产品保水性和品质的影响。结果显示:磁场辅助冷冻可以缩短肉饼通过最大冰晶生成带的时间,加快冷冻速率;解冻时降低解冻速率,减少解冻损失和蒸煮损失,降低自由水比例,提高不易流动水的比例,同时提高了肉饼的硬度、弹性、凝聚力和咀嚼性(P<0.05)。其中,4.5 mT交变磁场冷冻条件下肉饼通过最大冰晶生成带的时间较对照组缩短417 min,冷冻-解冻组中解冻损失和蒸煮损失分别降低59.62%和58.07%,硬度、弹性、凝聚力和恢复力显著高于对照组(P<0.01)。综上,磁场辅助在调理肉制品的冷冻和解冻等加工工艺中具有一定的发展潜力。We undertook this study in order to explore the impact of stationary magnetic field(SMF)and alternating magnetic field(AMF)treatments at different intensities(1.5 and 4.5 mT)combined with freezing and/or thawing on the water retention and quality of precooked meat patties.The results showed that magnetic field-assisted freezing shortened the time required to pass through the maximum ice crystal formation zone,thereby accelerating the freezing rate.In addition,it reduced the thawing rate,thawing loss and cooking loss,decreased the proportion of free water,increased the proportion of immobilized water,and improved the hardness,elasticity,cohesiveness and chewiness of meat patties(P<0.05).The 4.5 mT AMF treatment shortened the time required to pass through the maximum ice crystal formation zone by 417 min compared with the control group,and thawing loss and cooking loss decreased by 59.62%and 58.07%in the AMF-assisted freezingthawing group,respectively.Furthermore,the hardness,elasticity,cohesiveness and resilience were significantly higher than those of the control group(P<0.01).In summary,magnetic field-assisted processing holds potential in the freezing and thawing of prepared meat products.
