Problems solved by technology

[0005] Due to the low water content of fresh jujube, it cannot be directly extracted according to the general juice extraction method. Therefore, traditional jujube juice drinks are made from dried dates by boiling, beating, separating the pulp and core, and extracting juice. The active factors such as vitamin C rich in fresh jujube are almost lost
At present, there is no product on the market that extracts juice from fresh red dates without destroying the loss of vitamin C.

Embodiment 1

[0028] Pick fresh jujubes, manually select, remove miscellaneous, and remove pests and diseases, rinse with water, and soak the fruits in 0.1 to 3% (W) of stable chlorine dioxide or 0.1 to 3% (W) of peracetic acid solution for 5~ For 30 minutes, carry out pesticide reduction and sterilizing treatment, take it out and rinse it with sterile soft water until it is neutral, use manual pricking or pitting machine to cut, separate the pulp and core, add 0.2 to 2 times aseptic soft water to extract 20 to 90 Minutes, take the juice, add 0.1-1% compound preservative for fresh-keeping treatment, further crush it through a colloid mill, and grind it to a fineness of 2-50 μm, directly fill it with sterile aluminum foil composite bags or high-density polyethylene barrels, and store it at room temperature . The puree of fresh red dates is produced by traditional techniques such as blending to produce fresh jujube juice drinks.

[0029] The compound antistaling agent is 0.4% nisin, 0.075% s...

Embodiment 2

[0031] The production process is the same as in Example 1, wherein the compound preservative is, nisin 0.2%, sorbic acid (potassium) 0.05%, chitosan 0.3%, glycine 0.06%, ascorbic acid 0.06%, citric acid 0.01% , and the rest is water.

Embodiment 3

[0033] The production process is the same as in Example 1, wherein the compound preservative is, nisin 0.5%, sodium benzoate 0.02%, potassium sorbate 0.08%, paraben 0.01%, ascorbic acid 0.04%, phytic acid 0.1%, citric acid 0.3%, glycine 0.03%, the rest is water;

Abstract

The invention relates to a production method of primary pulp of fresh jujubes, which is characterized by comprising the following technical processes of: selecting fresh jujubes, rinsing with water to reduce pesticide, sterilizing, eluting the fresh jujubes in sterile water, shearing and crushing the fresh jujubes for denucleation, leaching for extracting juice, refreshing or instantly sterilizing juice at super-high temperature, finely crushing the fresh jujubes, and finally, carrying out cold-filling on the juice in an aseptical environment. The technical processes are performed at normal temperature, a proper amount of pure water is added and replenished for leaching, and then a natural refreshing agent is formulated or instant sterilization is performed at super-high temperature so that the fresh jujubes are directly juiced; the abundant vitamin C and other active factors of the fresh jujubes are not destroyed so that the pure natural properties of the fresh jujubes are kept, and the quality guarantee period of the juice is more than one year.

Description

technical field [0001] The invention relates to the technical field of food and beverages, in particular to a production method of fresh jujube puree. Background technique [0002] Jujube is rich in protein, fat, sugar, organic acid, carotene, thiamine, riboflavin, ascorbic acid, rich in 18 kinds of amino acids needed by the human body, and various trace elements such as calcium, phosphorus, iron and zinc; Its vitamin C content is 300-700mg / 100g, which is 100 times that of apples and 20 times that of citrus. It is commonly known as "natural vitamin pills"; Contains ketones, which have a good effect on softening blood vessels, prevent and treat heart disease, and high blood pressure; contain cyclic adenosine monophosphate, which has a curative effect on cancer. [0003] Chinese medicine studies believe that jujube is flat and sweet, nourishes the spleen and harmonizes the stomach, nourishes qi and promotes body fluid, regulates nutrition, detoxifies drugs, protects the liver...
