The invention relates to a method for comprehensively processing and utilizing raw ginger and discloses technical points and a method. The invention belongs to the field of agricultural product processing. In China, there is a long history of food and medicinal use of raw ginger, raw ginger development and utilization begun very early, main raw ginger products include ginger sheets, ginger sauce, sweet ginger and the like, the product quality is low, the utilization rate of the raw ginger resource is low, and through the development and utilization, and all parts of the raw ginger are fully used while products with high added values and high value increase effect are obtained. Products extracted from the raw ginger include raw ginger juice, raw ginger oil resin and raw ginger ultrafine powder. In the invention, the raw ginger is deeply processed by a combined production mode of squeezing juice, extracting ginger oil resin under a supercritical condition and grinding ultrafine raw ginger powder, the raw ginger juice is separated centrifugally, and the stability of the obtained raw ginger oil is high; ginger slag obtained after juice squeezing is treated by a supercritical carbon dioxide extraction method to obtain the raw ginger oil resin with high antioxidation activity; and ginger juice sediment and the ginger slag obtained after supercritical carbon dioxide extraction are treated by an ultrafine grinding method to obtain high-quality raw ginger ultrafine powder. In the raw ginger processing process, chemical additives are not used, the natural components of the raw ginger are not damaged, the raw ginger raw material is fully utilized without exerting bad influences on the environment, and the method is in accordance with an industrial philosophy of sustained development required by current social and economic development. The method can deeply and comprehensively develop raw ginger products in a large scale, helps to improve the comprehensive benefits of ginger.
