Problems solved by technology

The deficiency of this method is: the loss of some nutrients in red dates is more; It adopts spray drying technology or vacuum drying technology to process jujube powder, such as the Chinese invention patent with the patent application number of 01126824.7. The method of processing jujube powder is to pre-boil and beat the red dates, then add a single additive and then spray dry; the patent application number is 200410024273.6 Chinese invention patent, the method of processing jujube powder is to crush and beat jujube, add moisture-proof agent and compound drying aid to the refining liquid, and then spray dry
The third and fourth spray drying methods need extraction or beating, so that only the water-soluble components in the jujube are retained; while in the spray drying, there are still problems such as high temperature, large nutrient loss, easy sticking to the wall and not easy to powder

Embodiment 1

[0020] The processing method of jujube powder comprises the following steps:

[0021] 1) Raw material selection, cleaning, nuclear removal and slicing

[0022] Select jujubes with neat shape, natural color, large and thick flesh, and use fresh jujube fruits that are completely red and ripe without moths and mildew as raw materials. Fengluo jujube, broken head jujube and green jujube are detected;

[0023] Wash the selected fresh dates under tap water, the purpose is to clean the fresh dates as much as possible to remove the dirt on the surface of the dates and reduce pesticide residues and harmful microorganisms. Generally, it is advisable to wash twice with tap water;

[0024] Then manually or mechanically remove the jujube stones, and further remove the fruits of diseases and insect pests;

[0025] The fresh jujube slices after cleaning and pitting are 5-6mm thick, uniform in thickness, and sliced ​​quickly to avoid browning and Vc oxidation.

[0026] 2) Vacuum low-tempera...

Abstract

The invention discloses a method for processing date powder, which comprises the following steps of: selecting fresh red dates, cleaning, removing impurities, manually or mechanically removing date pits, and cutting into annular slices with the thickness between 5 and 8mm; performing vacuum drying on the sliced red dates for 2 to 4 hours under the conditions that the vacuum degree is between 60 and 600 Pa and the temperature is between 20 and 50 DEG C, and grinding into the date powder with the particle size between 200 and 300 meshes; and finally, sterilizing the date powder by microwaves, and performing vacuum packaging. The date powder prepared by the method maintains the nutrient components, color and flavor of the red dates as possible, and is cloudy solution after being mixed with water, and has the advantages of uniform and consistent texture, no floccule, settlement or layering, fresh mouthfeel and natural fragrance and sweetness.

Description

technical field [0001] The invention belongs to the technical field of jujube processing, and relates to a processing method of jujube powder. Background technique [0002] Jujube is rich in various nutrients and active substances, and is a natural health food. Modern scientific research shows that jujube has the functions of anti-tumor, anti-oxidation, anti-aging, anti-mutation, anti-radiation and protecting liver and spleen. The common jujube processed products in the Chinese market are mainly rough processed products such as drunk dates, candied dates, and jujube paste, and less processed products such as jujube powder. [0003] At present, the disclosed jujube powder processing methods are as follows: one is to directly grind the jujube powder into powder after drying. Not suitable for brewing. The Chinese invention patent with the patent application number 93111367.9 discloses the second method of processing jujube powder, which is made by cleaning and removing impur...
