Embodiment 1

[0026] Chlorophyll iron sodium salt is dissolved in water with a solution concentration of 13g / L and a pH value of 8.2. Calcium acetate is dissolved in water and its solution pH is 5.8 (the solution is ready-to-use). The Ca salt solution was slowly added to the ferric chlorophyllin sodium salt solution. At the same time, magnetically stir at a speed of 1000r / min to make it fully react at room temperature. The aging temperature is 60°C, and the aging time is 15 minutes. Separation by filtration and drying at 80°C to obtain black (dark brown) chlorophyllin iron calcium salt. Carry out the measurement of each index. Wherein, by AVATAR360 type Fourier transform infrared spectrometer and UV7652 spectrophotometer analysis, obtain iron chlorophyllin sodium salt and chlorophyllin iron calcium salt spectrogram (see attached Figure 1~4 ), and analyzed and compared, it was determined that the product was iron chlorophyll calcium salt.

[0027] The calculated yield is 88%

[0028] ...

Embodiment 2

[0037] Sodium iron chlorophyllin is dissolved in water and its solution pH is 9.0. Calcium acetate is dissolved in water and the pH of the solution is 6.8 (the solution is ready-to-use). The Ca salt solution was slowly added to the ferric chlorophyllin sodium salt. At the same time, magnetically stir at a speed of 1000r / min to make it fully react at room temperature. The aging temperature is 70°C, and the aging time is 20 minutes. Separation by filtration and drying at 60°C to obtain black (dark brown) chlorophyllin iron calcium salt.

[0038] The calculated yield is 90%

Embodiment 3

[0040] Sodium ferric chlorophyll is dissolved in water and its solution pH is 8.5. Calcium acetate is dissolved in water and the pH of the solution is 6.5 (the solution is ready-to-use). The Ca salt solution was slowly added to the ferric chlorophyllin sodium salt. At the same time, magnetically stir at a speed of 1000r / min to make it fully react at room temperature. The aging temperature is 80°C, and the aging time is 15 minutes. Separation by filtration and drying at 50°C to obtain black (dark brown) chlorophyllin iron calcium salt.

[0041] The calculated yield was 94%

[0042] Iron chlorophyllin calcium salt traits: small black particles with metallic luster. Insoluble in water and dilute hydrochloric acid, slightly soluble in acetone and ethanol, the solution is yellow-green, soluble in 1:1 hydrochloric acid, easily soluble in alkaline solutions with pH above 12 to obtain a yellow-green solution.

Abstract

The invention discloses a preparation method of a natural chlorophyll iron calcium salt and further obtains the natural chlorophyll iron calcium salt (also known as iron chlorophyllin calcium). In the method, the chlorophyll iron calcium salt is prepared from a chlorophyll iron sodium salt and a calcium slat used as raw materials through one-step direct substitution, wherein the chlorophyll iron sodium salt and the calcium slat are respectively dissolved in water according to the weight ratio; the pH value of reaction solution is 8-9; water solution of the Ca salt is slowly added into solution of the chlorophyll iron sodium salt, magnetic stirring is performed at the speed of about 1000r/min, and the reaction is performed fully at room temperature; and aging, separation and drying at the temperature of 50 DEG C-80 DEG C are further performed, thereby obtaining the black (dark brown) chlorophyll iron calcium salt. By adopting the method, the easily available raw material, namely the natural chlorophyll iron sodium salt is used for preparing a chlorophyll derivative, namely the chlorophyll iron (II) calcium salt, thereby realizing the simultaneous supplementation of iron and calcium for a human body and having no toxicity or side effects. The preparation method is simple and the yield is high. The chlorophyll iron calcium salt can be used as a medicament or a food additive and has very broad application prospects in the aspects of foods, medicines and the like.

Description

technical field [0001] The invention relates to a preparation method of natural pigment salt, in particular to a preparation method of natural chlorophyll iron calcium salt. Get natural calcium iron chlorophyllin, also known as calcium iron chlorophyllin. Background technique [0002] Chlorophyll, which is required for human survival, belongs to the magnesium porphyrin compound and is a natural pigment. Chlorophyll derivative products are obtained by replacing the magnesium ion in the center of the chlorophyll porphyrin ring with other metal ions, such as: copper chlorophyllin sodium salt, calcium chlorophyllin acid sodium salt, cobalt chlorophyllin acid sodium salt, iron chlorophyllin acid sodium salt etc., have excellent coloring effect, promote hematopoiesis, protect liver, anti-microbial, promote wound and ulcer healing and anti-mutation and other biological characteristics and unique pharmacological functions, easy to be absorbed by the human body and have no toxic sid...
