The invention provides an industrial production technology of deerskin protein oligopeptide. The industrial production technology comprises the following specific steps: 1, preparing a raw material; 2, slicing; 3, soaking for thawing; 4, mincing; 5, defatting; 6, grinding into a slurry; 7, salting out; 8, performing pressure filtration; 9, enzymolyzing; 10, performing ultrafiltration to obtain oligopeptide; 11, concentrating through nanofiltration interception, desalting and removing impurities; 12, sterilizing; 13, filling; 14, performing freeze drying; 15, pressing a bottle stopper and labeling. By the industrial production technology, the technology is simple, the design is reasonable, a natural resource is fully utilized, and high-added value industrial and large-scale production can be achieved. Hydrolysis is performed by using food-grade protease, so that the safety is high no side effects are caused; the deerskin protein oligopeptide can be used as an additive of a proprietary Chinese medicine and a functional health-care product or directly taken and can be also used as a cosmetic additive.
