Abstract: With the development of modern agricultural technology and the in-depth research of the biological effect of magnetic field, magnetic field technology has been widely used in various fields of agricultural science. Appropriate magnetic field conditions such as proper intensity, waveform, and frequency can give rise to specific non-thermal effects on agricultural raw materials, which can regulate the metabolism, respiration and mass and heat transfer efficiency of biological tissues and cells, mainly by influencing water cluster, cell morphology, biomolecular activity, and gene expression. Therefore, compared with other physical processing methods, its effects manifest more slowly. Moreover, the same magnetic field parameters could show different effects on different processed objects. At present, magnetic field technology has been verified and applied in the field of agricultural products processing, mainly including assistance in the preservation, sterilization, fermentation, and extraction of agricultural products. This article summarizes the current status of research and application of magnetic field biochemical technology in agricultural products processing, and discusses the existing problems and future trends, which will provide a reference for researchers interested in the application of this technology in the agricultural field.
