摘要： This study aims to investigate the influence of oscillating magnetic fields on the deep supercooling of water and the supercooling storage of fruits. The results showed that by utilizing a 6 mT/50 Hz oscillating magnetic field, water (1 ml) was able to be maintained at -18 degrees C for 24 h, achieving deep supercooling. Combining magnetic field with oil-sealed water enhanced supercooling compared to oil sealing alone. By adding an oscillating magnetic field, fruits were maintained at a temperature of -5 degrees C for 12 h. The supercooled samples exhibited a texture and color that were close to those of fresh samples and also experienced a reduction in water loss of up to 30.25% in comparison to frozen samples that were not treated by magnetic field treatment. The proposed method achieved significant supercooling and improved food quality using an easily obtainable type of magnetic field.
