Problems solved by technology

[0004] At present, jujube is mainly used for fresh fruit consumption, and there are few deep-processed jujube products. Although there are related reports on the research of concentrated jujube juice, the disadvantage of the concentrated jujube juice developed by it is that it does not retain the ingredients contained in jujube to the greatest extent. Nutritional ingredients, causing the loss of part of the nutritional ingredients, after searching, no technical solution identical to that of the present invention was found

Embodiment 1

[0028] The production process of concentrated jujube turbid juice specifically adopts the following steps:

[0029] 1) Washing and picking the mature jujubes, removing the seeds, and then crushing the jujubes in a high-speed crusher through stirring and shearing force;

[0030] 2) Place the broken jujube in 3 times the water, and extract at 45°C for 90 minutes;

[0031] 3) Send the leached jujube to a screw press (pressing specification: 1.5 tons) to extract the original jujube juice, screw speed: 400 / min, filter aperture: 0.3mm;

[0032] 4) Continue to add water and pulp enzymes to extract the pomace in the first squeeze for 30 minutes, and perform a second squeeze; then filter the mixed juice of the first and second squeezes through a 120-mesh pipeline filter to obtain turbid jujube juice;

[0033] 5) Sterilize the filtered jujube turbid juice at 85°C for 30s to remove microorganisms in the juice;

[0034] 6) The sterilized mixed turbid juice is sent to a homogenizer for e...

Embodiment 2

[0038] The production process of concentrated jujube turbid juice specifically adopts the following steps:

[0039] 1) Wash and select the mature jujubes, remove the seeds, and then crush the jujubes in a high-speed crusher through stirring and shearing force;

[0040] 2) Place the broken jujube in 4 times the water, and extract at 48°C for 120 minutes;

[0041] 3) Send the leached jujube to a screw press (pressing specification: 1.5 tons) to extract the original jujube juice, screw speed: 400 / min, filter mesh diameter: 0.3mm;

[0042] 4) Continue to add water and fruit pulp enzyme extraction for 30 minutes after the first squeezed pomace, and carry out the second squeeze, and the mixed juice of the first and second squeezes will pass through a 120-mesh pipeline filter and enter the cloudy juice temporary storage tank to obtain the jujube cloudy juice.

[0043] 5) The filtered ones are sterilized at 85°C for 30s to remove microorganisms in the juice;

Abstract

The invention provides a preparation method of a concentrated honey raisin tree cloudy juice and belongs to the technical field of deep processing of agricultural products. The method can improve the utilization rate of raw materials, and the prepared honey raisin tree juice has high nutrition and honey raisin tree flavor. The preparation method is as below: cleaning mature honey raisin tree fruits and removing stems and seeds of the fruits; soaking the crushed honey raisin tree fruits in water; extracting juice from the soaked honey raisin tree fruits twice; mixing the first extracted juice with the second extracted juice and filtering; sterilizing the filtered juice; and squeezing and grinding the sterilized juice, and concentrating to obtain the concentrated honey raisin tree cloudy juice. The invention provides a beverage processing process by using honey raisin tree as the raw material. The method can take advantage of the unique local resources for processing, improve the income of farmers and drive the enthusiasm of planting, and has increased business promotion space.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural and sideline products, and in particular relates to a method for preparing concentrated jujube turbid juice. Background technique [0002] Jujube, also known as Wanweiguo, Jingouzi, Jishouzi, Wood Honey, Pear Jujube, Lycium, etc., belongs to Rhamnaceae, and Citrus aurantium is a woody plant. Jujube is a positive tree species, which grows on sunny hillsides, valleys, ditch sides and roadsides or is cultivated; it is mainly distributed in Shaanxi, Jiangxi, Anhui, Zhejiang, Guangdong, Fujian, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan and other provinces. In the wild or semi-wild state, there are also returning farmland to forests to plant jujubes artificially. [0003] Jujube has high nutritional value. According to the analysis and determination of the scientific research department, its fleshy fruit stem contains 24% of sucrose, 9.5% of glucose and 7.92% of fructose....
