摘　　要：现在各冰箱厂商越来越重视冰箱的保鲜功能,各种保鲜冰箱和带有保鲜模块的冰箱在市场上日益广泛。本文研究了高压静电场对新鲜牛里脊肉在冻结和解冻过程中保鲜效果的提升作用。主要的研究目标为探索高压静电场对牛里脊肉的冻结、解冻曲线和微观的肌纤维细胞的影响。研究发现适当场强的高压静电场在肉的冻结及解冻过程都有提升其保鲜效果的作用。高压静电场作为一种极具潜力的保鲜模块,值得在冰箱上进行广泛研究与应用。Food preservation ability of refrigerators gets more attentions by the manufactures. On the market there are more refrigerators broadcasting the food preservation function. In this article we studied the freezing and thawing process of beef tenderloin meat in high voltage electrostatic fields to improve the preservation effect. The major studied factors are freezing and thawing curves and the integrity of myofibers under microscopy. We found under the optimized electrostatic field intensity beef tenderloin meat has improved preservation factors. The high voltage electrostatic field is potential to improve food preservation characteristics, and it is considered to deserve further study and be applied on refrigerators.
