Although freezing is the most popular method for long-term food preservation, the formation of ice crystals during the process often leads to degradation of the product quality. Recently, we demonstrated that the presence of oscillating magnetic fields (OMFs) can hinder ice crystallization (10.1016/j.cryobiol.2020.05.005, [1]). In this data that we investigated the effects of OMFs on freezing tuna blocks using the Cell Alive System (CAS) (ABI Co. Ltd., Chiba, Japan) developed as a rapid freezer unit supplemented with an OMF generator. The center temperature of tuna blocks was monitored during air blast freezing (ABF) or ABF combined with CAS (ABF-CAS). The time taken to acquire the freezing temperature (-20 °C) was significantly ( < 0.05) shortened with ABF-CAS compared to ABF. The time taken for ice crystal formation (crystallization time) was slightly shorter in case of the ABF-CAS system relative to ABF ( = 0.08497).
尽管冷冻是长期保存食物最常用的方法，但在此过程中冰晶的形成往往会导致产品质量下降。最近，我们证明了振荡磁场（OMF）的存在可以阻碍冰晶形成（10.1016/j.cryobiol.2020.05.005，[1]）。在本数据中，我们使用作为配备OMF发生器的快速冷冻装置开发的细胞存活系统（CAS，日本千叶市ABI有限公司）研究了OMF对冷冻金枪鱼块的影响。在鼓风冷冻（ABF）或ABF与CAS联合使用（ABF-CAS）过程中监测金枪鱼块的中心温度。与ABF相比，ABF-CAS显著（<0.05）缩短了达到冷冻温度（-20°C）所需的时间。相对于ABF，ABF-CAS系统的冰晶形成时间（结晶时间）略短（=0.08497）。
