Embodiment 1

[0032] see figure 1 , a preparation method of red jujube concentrated clear juice with high cAMP content, comprising the following steps:

[0033] 1. Raw material selection and pretreatment:

[0034] 1.1 The raw materials are jujubes that have been selected to remove diseases, insect pests and mildew;

[0035] 1.2 The selected jujube raw materials are washed with clean water to clean the sediment;

[0036] 1.3 Use a blade to make several cuts in the jujube for easy rehydration.

[0037] 2. Softening and rehydration

[0038] 2.1 When rehydrating, add pure water at 50°C with a volume ratio of jujube:water=1:3, and keep warm in a water bath at 50°C for 60 minutes;

[0039] 2.2 Stirring during rehydration is beneficial to the full rehydration of red dates;

[0040] 2.3 After rehydration, take out the red dates and remove the pits, and keep the remaining water after removing the red dates; minimize the loss of pulp when removing the red dates.

[0041] 3. Crushing and beating...

Abstract

The invention discloses a method of preparing concentrated clear red jujube juice with high cAMP content, which comprises the following steps: taking out red jujube after rehydration, denucleating and then crushing pulp for preparing the red jujube thick liquid; conveying the red jujube after enzymolysis by pectinase into a juicer for squeezing, and filtering to obtain the red jujube juice; adding pectinase, amylase and cellulose into the red jujube juice for heat-preservation and enzymolysis for 60-90 minutes; and clearing, conducting concentration sterilization, and finally bulking. The concentrated clear red jujube juice prepared by the invention is clear and transparent, has the cAMP content being larger than or equal to 100 mg/Kg and soluble solid state material being larger than or equal to 60.0 Brix, is deposit-free and suspension-free, has brownish red color and does not have impurities which can be seen by naked eyes; and the concentrated juice is diluted to the soluble solidstate material being 60.0 Brix, and the juice has inherent fragrance and flavor of red jujubes and is free from extraneous odor.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable juice processing, and relates to a preparation method of red date concentrated clear juice with high cAMP content. Background technique [0002] Jujube is a characteristic dried fruit originating in China. It has a cultivation history of more than 4,000 years in China. It is the fruit of the Rhamnaceae Jujube plant. Red jujube has thick skin and thin flesh, sweet and crisp, rich in nutrition, known as "woody food"; rich in protein, sugar, microorganisms, minerals, saponins, alkaloids and flavonoids, etc., it is a high-quality health care food. The cyclic adenosine monophosphate (cAMP) rich in jujube has anti-allergic effects, inhibits the growth of cancer cells and promotes the transformation of cancer cells into normal cells, and also has a certain effect on the prevention and treatment of coronary heart disease. The development of concentrated jujube juice has a very good promotion...
