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.
