The invention relates to the storage of raw material of ginger, in particular to a method for storing raw material of ginger at low temperature, belonging to the technical field of ginger processing. The method comprises the following steps: choosing the raw material of ginger, cleaning, grading, pickling, acidifying, packaging and refrigerating. Aiming to overcome the problems that the conventional ginger is pickled by excess salt and sulphur so that the flavor and the components of the ginger are lost and the nutrients and the active components of the ginger are damaged and browned and havepotential safety hazards, the concentration of the salt is reduced and the sulphur preparation is not used. Therefore, the quality and the preservation rate of the raw material are improved, and the raw material for producing high-quality ginger product is guaranteed. In addition, the use amount of the salt is reduced, and the use amount of water for desalting is reduced, thus the purposes of lowering cost, saving water and reducing emission are achieved. The method has the advantages of operation convenience and reliability and high production efficiency. The damage to the quality of the rawmaterial of the ginger due to the adoption of the ginger salting storing process is reduced to the maximum extent, and the quality of the ginger product is improved significantly.
