The invention relates to a fermenting agent for reducing biogenic amine in meat products by compound-bacteria temperature-shift fermentation and a fermentation method thereof, belongs to the technical field of biological fermentation of meat food, and particularly relates to a method of reducing biogenic amine in meat products by compound-bacteria temperature-shift fermentation. The method includes: adding compound bacteria into a meat product to be fermented all at once, performing low-temperature lactobacillus pentosus fermentation at 20-30 DEG C, immediately raising the fermentation temperature after the low-temperature fermentation is finished and performing medium-temperature fermentation at 35-45 DEG C with lactobacillus plantarum and lactobacillus coryniformis, namely, the meat product is fermented by a two-step method that is low temperature firstly and medium temperature secondly by utilization of the compound bacteria. The fermenting agent comprises 8.0-12.0 g of glucose, 2.0-3.0 g of pentose and 2.0-3.0 g of fructosan. The fermenting agent and the fermentation method are advantageous in that, by two fermentation steps at different temperatures and with different bacteria or bacterium compositions, the content of the biogenic amine in the meat product is obviously lower than that of a meat product only subjected low-temperature fermentation or only subjected to medium-temperature fermentation; and the flavor of the meat product subjected to the low-temperature fermentation firstly and medium-temperature fermentation secondly is significantly improved.
