Embodiment 1

[0024] Sodium iron chlorophyllin is dissolved in water to make the solution concentration 0.67g / 100ml. Add the magnesium salt solution into the ferric chlorophyllin sodium salt solution, stir at a speed of 1000r / min, and make it fully react at room temperature. Aging at room temperature for 5h. Separation by filtration and drying at 60°C for 2 hours to obtain black (dark green) iron-magnesium chlorophyll. Carry out the measurement of each index. Wherein, by AVATAR360 type Fourier transform infrared spectrometer, UV7652 spectrophotometer, obtain chlorophyll iron sodium salt and chlorophyll iron magnesium salt spectrogram (see attached Figure 1~4 ), and analyzed and compared, it was determined that the product was chlorophyll iron-magnesium salt.

[0025] The calculated yield was 72%.

Embodiment 2

[0027] Sodium iron chlorophyllin is dissolved in water to make the solution concentration 0.67g / 100ml. Add the magnesium salt solution into the ferric chlorophyllin sodium salt solution, stir at a speed of 1000r / min, and make it fully react at room temperature. Aging at room temperature for 7h. Separation by filtration, and drying at 60°C for 2.5 hours to obtain black (dark green) chlorophyll iron-magnesium salt. Carry out the measurement of each index.

[0028] The calculated yield was 78%.

Embodiment 3

[0030] Sodium iron chlorophyll salt is dissolved in water with a solution concentration of 0.67g / 100ml. Add magnesium salt solution, stir at a speed of about 1000r / min, and make it fully react at room temperature. The aging time is 9h at room temperature. Separation by filtration, and drying at 60°C for 3 hours to obtain black (dark green) chlorophyll iron-magnesium salt. Carry out the measurement of each index.

[0031] The calculated yield was 74%.

[0032] Salt formation analysis of chlorophyll iron and magnesium:

[0033] 1. Judging from the changes in the experimental phenomena, after dissolving sodium iron chlorophyllin in water, the color of the solution is dark green. When adding a colorless magnesium salt solution, black precipitates are immediately produced, indicating that new substances are formed.

[0034] 2. Ultraviolet-visible absorption spectrum (UV) analysis

[0035] See attached figure 1 , 2 and the following table. From the analysis of the UV spectrum,...

Abstract

The invention discloses a method for preparing a natural chlorophyll iron magnesium salt and obtains the natural chlorophyll iron magnesium salt (namely, iron chlorophyllin magnesium). The method includes that sodium ferrous chlorophyllin and magnesium salts serve as raw materials, and direct substitution and one step manufacture are adopted. The sodium ferrous chlorophyllin and the magnesium salts are dissolved in water according to a mass ratio, adding a magnesium salt solution into a sodium ferrous chlorophyllin solution, magnetically stirring the mixture at a speed of about 1000r / min, and reacting the mixture fully at a room temperature; and performing aging, separation and drying at a temperature of 60 DEG C for 2 to 3 hours to obtain the back (deep green) chlorophyll iron magnesium salt. The yield is calculated to be 72% to 78%. The resultant is explained to be the chlorophyll iron magnesium salt through color change and precipitation formation in the preparation, nature determination of an ultraviolet (UV) spectrogram and an infrared (IR) spectrogram, and spectrogram analysis. The preparation method is simple and direct, the cost is low, the pollution to the environment is small, and the yield is high. Materials needed by the synthesis are easy to obtain, non-toxic and harmless, the price is low, and the method has infinite development and application prospects in aspects of food, medical drugs and the like.

Description

technical field [0001] This experiment has invented a kind of natural chlorophyll salt and its preparation method, specifically a kind of preparation method of natural chlorophyll iron magnesium salt. The obtained natural chlorophyll iron magnesium salt is also called iron chlorophyll magnesium. Background technique [0002] Chlorophyll is a natural pigment complexed by magnesium ions to the porphyrin ring structure, and there are many kinds of derivatives. Such as: copper chlorophyllin sodium salt, chlorophyllin zinc sodium salt, chlorophyllin cobalt sodium salt, chlorophyllin iron sodium salt, etc. With the in-depth research on chlorophyll and its derivatives, it is found that it has great potential in the fields of food, daily chemical industry, medicine and health care. Very broad space for development. Because chlorophyll and its derivatives are non-toxic or low-toxic, they can be used as food additives in vegetables, meat, sugar and wine; the strong antioxidant prope...
