The carnosine-enriched animal protein powder is animal protein powder of which the carnosine contentis 5-7wt% and which is from leftover materials produced after processing of animal meat products. The preparation method comprises the steps of performing grinding, performing first-class film filtration, performing hydrolysis, performing second-class film filtration, performing bioconversion, performing biosynthesis and performing drying. The leftover materials produced after processing of animalmeat products are used as raw materials, so that the carnosine-enriched animal protein powder of which the carnosine content is as high as 5-7wt% is directly prepared, effective utilization of wasteresources is realized, the nutrient efficacy of the animal protein powder can be improved, the carnosine-enriched animal protein powder is low in cost, and large-scale production is easy to realize.
