The invention relates to a production method of a medium-temperature sausage product which has the high quality and can be stored at the normal temperature for a long time. The medium-temperature sausage product is prepared from raw material meat, auxiliary materials, spore germination factors and a quality preservation agent through processing; the specific processing technology comprises steps as follows: material selection, pre-processing, meat mincing, meat stuffing production, vacuum filling, spore germination, hot processing, discharging from a furnace and cooling, packaging and medium-temperature sterilization. According to the method, under the coaction of thermal stimulation and the germination factors, spores in the product are effectively killed at the medium temperature of 90-110 DEG C, meanwhile, the quality preservation agent is added, so that vitamins, amino acid and fatty acid in the product are protected, and the product has the high nutritional value and the good flavor.
