The invention discloses preparation of digestion-free protein chocolate with a cocoa liquor and cocoa butter liquid-solid principle as a carrier. The problems that peptide is poor in taste and fast toeat are solved. Incubated living embryo protein of fertilized eggs and soybean protein serve as the raw materials, living embryos and the soybean protein are mixed and subjected to ultra-long-time enzymolysis, a pair protein digestion-free protein liquid product is obtained, a powder product is obtained through concentration, spraying and drying, and the powder product, cocoa liquor, cocoa butterand the like can be mixed, heated, shaped and cooled to obtain a finished product. The product aims to relieve the brain fatigue and the pressure of students and improve the learning efficiency, fatigue is a pressure response which is closely related to the body and mind, quick protein supplementation is the most important way for fatigue eliminating, and digestion-free protein is the unique substance which can be rapidly supplemented and does not need to be digested. The brain fatigue reflecting index is oxidized hemoglobin, and when the brain is fatigue, the index is increased, thinking isslow, and the learning efficiency is reduced. Experiments show that when the students eat peptide during learning, the oxidized hemoglobin is reduced, increase is inhibited, the brain is refreshed, and thinking is quick.
