Abstract

The invention provides a process for making concentrated red jujube juice. The process comprises the following steps: selecting, pulping, pre-cooking, filtering, performing enzymolysis, clarifying, performing ultrafiltration, concentrating, sterilizing and the like, thereby obtaining the uniform and thick concentrated red jujube juice. The concentrated red jujube juice is brownish red to medium brown, has due flavor of red jujubes and is odorless, moderate in sourness and sweetness and pure in taste; any visible impurity is not seen under normal visual acuity, and any mildew is avoided; and according to the process, chitosan is adopted for precipitating, secondary diatomite filtration and secondary ultrafiltration are performed, the turbidity of the finished product is reduced, the light transmittance is improved, secondary turbidity of the concentrated red jujube juice is avoided, and the aim of prolonging the quality guarantee period of the product is achieved.
