Embodiment 1

[0019]

[0020] Preparation:

[0021] S1. Batching reaction: add the above-mentioned raw materials into the reaction kettle in proportion, and react at 65°C and pH 5.3 for 0.5h; when the pH of the reaction solution reaches 6.1, keep it warm for 5min;

[0022] S2, primary homogenization: the reaction liquid enters the homogenizer after being filtered through a 100-mesh pipeline filter under the condition of 60MPa, and the feed rate is controlled to be 500L / h, and the filtrate is collected after homogenizing for 30 minutes;

[0023] S3, secondary homogenization: the filtrate obtained in step S2 is filtered under the condition of 90MPa using a 500-mesh screen and enters the homogenizer. The feed rate is controlled to be 120L / h, and the homogenization is 150min. The raw material solution was left standing overnight;

[0024] S4. Spray drying: under the condition of 200°C, use the instantaneous high-temperature technology of spray drying to dry the supernatant of calcium aspart...

[0028]

[0029] Preparation:

[0030] S1. Batching reaction: add the above-mentioned raw materials into the reaction kettle in proportion, and react at 85°C and pH 6.0 for 1.0h; when the pH of the reaction solution reaches 6.5, keep warm for 10min;

[0031] S2, primary homogenization: the reaction liquid enters the homogenizer after being filtered through a 100-mesh pipeline filter under the condition of 80MPa, and the feed rate is 1000L / h, and the filtrate is collected after homogenizing for 60 minutes;

[0032] S3. Secondary homogenization: the reaction liquid after the first homogenization is filtered under the condition of 130MPa using a 500-mesh screen and then enters the homogenizer. The feed rate is 200L / h, and the homogenization is 300min. The solution was left to stand overnight;

[0033] S4. Spray drying: under the condition of 180°C, use the instant drying technology of spray drying to dry the supernatant of calcium aspartate after standing, and control the mois...

Embodiment 3

[0037]

[0038] Preparation:

[0039] S1. Batching reaction: add the above-mentioned raw materials into the reaction kettle in proportion, and react at 70°C and pH 5.5 for 1 hour; when the pH of the reaction solution reaches 6.5, keep it warm for 8 minutes;

[0040] S2, primary homogenization: the reaction solution enters the homogenizer after being filtered through a 100-mesh pipeline filter under the condition of 70MPa, the feed rate is 800L / h, and the filtrate is collected after homogenization for 60 minutes;

[0041] S3. Secondary homogenization: the reaction solution that has been homogenized once is filtered under the condition of 120MPa using a 500-mesh screen and then enters the homogenizer. The solution was left to stand overnight;

[0042] S4. Spray drying: under the condition of 250°C, use the instant drying technology of spray drying to dry the supernatant of calcium aspartate after standing, and control the moisture content of the product to not be higher than...

The preparation method is simple and convenient and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and in particular relates to a preparation method of calcium aspartate. Background technique [0002] Calcium is an essential element in the human body. In addition to making up the bones and teeth of the human body, it also participates in various physiological activities. According to relevant nutritional survey data, the residents of our country generally lack calcium nutrition, and the related diseases caused by calcium deficiency are well known to the public, and calcium supplementation is gradually attracting people's attention. At present, the calcium agents sold on the market include calcium carbonate, calcium lactate, calcium hydrogen phosphate, calcium citrate, calcium amino acid chelate and so on. [0003] Calcium aspartate is a kind of amino acid chelated calcium, which is made by refining every two amino acid molecules and one calcium ion under special conditions of high pre...
