| 为了提高冻肉解冻速率、减少解冻过程氧化劣变，本文研制了一台高压静电解冻柜，进行了解冻羊胴体的实验研究。结果表明：随着电场场强的增加，解冻时间缩短、汁液流失率降低、高压电场能抑制细菌生长，改善羊胴体解冻后的色泽。实验测得电场强度为12.5 kV/m，与未加电场相比，解冻时间缩短11.1%，汁液流失率降低49.6%，微生物菌落总数减少了一个数量级，且解冻后羊胴体外观新鲜，肉色泽差异显著。本研究为提高羊胴体解冻效率和品质，提供了新方法。 |

| Abstract: |
| In order to improve the thawing rate and decrease the oxidation deterioration of frozen meat during thawing process, a high voltage electrostatic thawing device was designed, and frozen lamb thawing was studied using the thawing device. The results indicate that with the increasing of electric field intensity, thawing time and juices loss was decreased, the growth of bacteria was inhibited, the color and luster of lamb thawing was improved. Compared with that without high voltage electrostatic field, when the electric field intensity was 12.5 kV/m, the time of thawing frozen lamb was shorten 11.1%, the rate of juices loss was decreased 49.6%, the total microbial counts reduced an order of magnitude and the appearance of lamb was fresh, color and luster difference was obvious. This study provides a new method for improving efficiency and quality of lamb thawing. |
