Embodiment 1

[0187] The preparation method of jujube powder comprises the following steps:

[0188] 1) Wash the selected red dates and pre-cook them. The pre-cooking temperature is 70°C, the ratio of material to liquid of red dates and water is 1:5, and the pre-cooking time is 10 minutes to obtain pre-boiled red dates juice;

[0189] 2) removing the core of the pre-boiled jujube juice obtained in step 1) and crushing it into a slurry to obtain jujube pulp;

[0190] 3) Add 0.24% citric acid, 0.14% ascorbic acid and 0.08% sodium sulfite in weight percentage to the jujube pulp obtained in step 2), and adjust the pH to 6.0 to obtain the color-protecting jujube pulp;

[0191] 4) Add pectinase to the color-protecting jujube pulp obtained in step 3) for enzymolysis, the amount of pectinase added is 0.01% by weight, the enzymolysis temperature is 30°C, and the enzymolysis time is 80 minutes to obtain enzymolysis red dates pulp;

[0192] 5) The enzymolyzed jujube pulp obtained in step 4) is vacuu...

Embodiment 2

[0197] The preparation method of jujube powder comprises the following steps:

[0198] 1) Wash the selected red dates and pre-cook them. The pre-cooking temperature is 90°C, the material-liquid ratio of red dates to water is 1:7, and the pre-cooking time is 30 minutes to obtain pre-cooked red dates juice;

[0199] 2) removing the core of the pre-boiled jujube juice obtained in step 1) and crushing it into a slurry to obtain jujube pulp;

[0200] 3) Add 0.24% citric acid, 0.14% ascorbic acid and 0.08% sodium sulfite in weight percentage to the jujube pulp obtained in step 2), and adjust the pH to 6.5 to obtain the color-protecting jujube pulp;

[0201] 4) Add pectinase to the color-protecting jujube pulp obtained in step 3) for enzymolysis, the amount of pectinase added is 0.03% by weight, the enzymolysis temperature is 50°C, and the enzymolysis time is 120 minutes to obtain the enzymolyzed red dates pulp;

[0202] 5) The enzymolyzed jujube pulp obtained in step 4) is vacuum he...

[0207] The preparation method of jujube powder comprises the following steps:

[0208] 1) Wash the selected red dates and pre-cook them. The pre-cooking temperature is 80°C, the material-liquid ratio of red dates to water is 1:6, and the pre-cooking time is 20 minutes to obtain pre-cooked red dates juice;

[0209] 2) removing the core of the pre-boiled jujube juice obtained in step 1) and crushing it into a slurry to obtain jujube pulp;

[0210] 3) Add 0.24% citric acid, 0.14% ascorbic acid and 0.08% sodium sulfite in weight percentage to the jujube pulp obtained in step 2), and adjust the pH to 6.3 to obtain the color-protecting jujube pulp;

[0211] 4) Add pectinase to the color-protecting jujube pulp obtained in step 3) for enzymolysis, the amount of pectinase added is 0.02% by weight, the enzymolysis temperature is 40°C, and the enzymolysis time is 100 minutes to obtain the enzymolyzed red dates pulp;

[0212] 5) The enzymolyzed jujube pulp obtained in step 4) is vacuum ...

Abstract

The invention discloses a making method of red date powder. The making method includes the steps of selecting red dates, cleaning, pre-boiling, removing stones, adjusting acidity, protecting the color, allowing for enzymolysis, concentrating, adding anticaking agent, homogenizing, spray-drying, labeling, spraying the code, and boxing. The making method has the advantages that extraction rate of the method is 57.95%, the red date powder is 4.23% in water content and yellow, granules of the red date powder are even without caking, the red date powder has strong flavor of red date and the inherent taste of red date, and the red date powder which is fully dissolvable can be dissolved into solution in red of red date with no impurities visible to naked eyes.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a preparation method of jujube powder. Background technique [0002] date( Ziziphusjujuba Mill. ) is a plant of the genus Jujube in Rhamnaceae, which is native to my country and has a cultivation history of at least 3,000 years. It is one of the unique and important fruit trees in my country. At present, jujube trees are cultivated in about 500,000 ha across the country 2 , of which the five provinces of Hebei, Shandong, Henan, Shanxi and Shaanxi account for 90% of the total area under cultivation. In 2007, the total output of jujube fruit in China was about 1 million tons, accounting for 98% of the world's total output. [0003] With the adjustment of Xinjiang's agricultural planting structure, Xinjiang's jujube industry has achieved rapid development. In recent years, Xinjiang has vigorously implemented the characteristic agricultural development strategy and brand strategy, ...
