The invention discloses a preparation process of red date condensed juice high in cAMP content. The preparation process includes the following steps of firstly, conducting separating, washing and smashing; secondly, conducting hot water extraction; thirdly, conducting cooling and heat preservation enzymic method oriented conversion; fourthly, adding composite enzyme preparations; fifthly, inactivating enzymes; sixthly, conducting centrifugation; seventhly, conducting filtration; eighthly, conducting concentration and pasteurization; ninthly, conducting filling. Compared with the prior art, the preparation process has the advantages that the process is simple, the production period is shortened, and the energy loss is reduced; extraction is conducted after smashing is conducted, and therefore extraction of nutritional ingredients in red dates can be improved; by means of the extraction and enzymolysis combined method, the juice yield is greatly improved, the processing time is greatly shortened, and the cyclic adenosine monophosphate content in red date juice is improved; date peel is utilized, and the cAMP content is improved; preparations of pectinase, cellulose and protease are used in a composite mode, and the hydrolysis capacity of enzymic preparations is improved; the step-by-step enzymolysis and extraction process is adopted, and interference between related enzyme preparations is avoided.
