The invention discloses a production method of barley leaf and wheat germ compound beverage. The production method is characterized by comprising the steps of taking barley leaves as raw materials, performing impurity removal, high pressure cleaning, purifying rinsing, artificial cleaning, cutting, leachating, withering, oxidative fermentation, evaporation and sizing, primary drying, secondary drying, magnetic sieving, excessive metal detection, cutting and crushing, water-cooling crushing and low-temperature wall breaking to prepare barley seedling powder, and then adding small-molecular wheat germ powder and mixing to prepare the solid beverage. According to the solution, by scientific combination of raw material components of barley leaves and wheat germs, the barley leaf and wheat germ resources are fully used, and the type of the barley leaf and wheat germ compound solid beverage is enriched; meanwhile, by the application of a modern food processing technology and a biological technology, the shortcomings in the prior art are overcome, and the beverage with the characteristics of nature, nutrition, convenience, safety, good taste and the like is prepared; people can eat the beverage frequently to fulfill the aims of nourishing the life and protecting the health.
