Embodiment 1

[0012] Example 1. A jujube powder, the jujube powder is light yellow powder, has the unique flavor and nutritional components of jujube, the water content is ≤5%, the reducing sugar content is 20%-23%, the total sugar content is 29%-31%, and the total acid The content is 0.10%-0.11%, and it becomes a clear solution after brewing.

Embodiment 2

[0013] Example 2. A processing method of jujube powder.

[0014] (1) Select fully mature jujube raw materials, clean them, moderately soften and crush them after baking, add softened water at a ratio of 1:4 to 1:5, and add pectin at a ratio of 0.5‰ of the weight of raw materials Enzyme, heat preservation and leaching at 45-55°C for 2 hours, then filter with a 100-mesh filter cloth to obtain jujube juice.

[0015] (2) add the maltodextrin of its soluble solid content 60% in jujube juice, 1% sodium carboxymethyl cellulose, 1% gum arabic and 1% sodium tripolyphosphate, feed liquid temperature is controlled at After fully stirring at about 50°C, add it to a high-pressure homogenizer for homogenization, and control the pressure of the first-stage valve to 30MPa, and the pressure of the second-stage valve to 10MPa.

[0016] (3) Concentrate the soluble solid content of jujube juice to 18% by using vacuum concentration equipment, and then sterilize at 95° C. for 10 seconds.

Abstract

A jujube powder is prepared from red jujube through extracting juice by pectinase method, adding proper additives, high-pressure homogenizing, and spray drying. It contains water (0-5%), reducing sugar (20-23%), general saccharide (29-31%) and total acid (0.1-0.11%).

Description

Technical field [0001] The invention relates to a jujube powder and a processing method thereof. Background technique [0002] Jujube is rich in nutrition, has the functions of nourishing qi and blood, invigorating the spleen and stomach, quenching thirst and promoting body fluid, strengthening the mind and strength, and has a good health care effect. 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] According to data retrieval, there are two main methods of processing jujube powder that have been disclosed: one is to directly grind red dates into powder after drying. And not suitable for brewing. The 2nd, adopt spray drying technology or vacuum drying technology to process jujube powder, as the method for processing jujube powder that the patent application number is 01126824.7 is after the precooking beating of red...
