Example Embodiment

[0033] Example 1

[0034] (1) Select Suaeda salsa in the vigorous growth period, take the tender stems and leaves, wash them repeatedly with warm water 3 times, and centrifuge for dehydration with a centrifuge.

[0035] (2) Chop the dehydrated Suaeda salsa stems and leaves and grind them into a slurry with a grinder. Add low-temperature cellulase to the slurry and stir evenly, enzymatically hydrolyze at 22°C for 18 hours, stirring constantly .

[0036] (3) Add ethanol with a mass concentration of 75% to the slurry after enzymatic hydrolysis. The added amount is 4 times that of the slurry, shake and extract for 0.5 hours in a vibrating mill, separate the solid and liquid, and then add the separated solid material The 75% ethanol that is 3.5 times the solid material is again shaken and extracted in a vibration mill for 0.5 hours, solid-liquid separation, and the liquid materials obtained by the two separations are mixed to obtain a chlorophyll extract.

Abstract

The invention discloses an extraction preparation method for sodium ferrous chlorophyllin and sodium ferrous chlorophyllin prepared through the extraction preparation method. The extraction preparation method comprises the following steps: (1) selecting suaeda salsa at the vigorous growth period, taking tender stems and leaves, cleaning and dehydrating; (2) grinding the stems and leaves of the dehydrated suaeda salsa into pulp, adding low temperature cellulase into pulp materials, uniformly stirring, and performing enzymolysis for 8-20 hours; (3) adding an extraction solvent, performing two-time extraction in which shaking extraction is carried out in a shaking device for 0.5-1 hour each time, and performing solid-liquid separation, so as to obtain a chlorophyll extracting solution; (4) dropwise adding a NaOH solution into the extracting solution for saponification reaction, then, performing vacuum rectification, extracting by using petroleum ether, and taking the sodium chlorophyllin solution at the lower layer; (5) adjusting the pH value of the hydrochloric acid to be 2-3, dropwise adding a ferrous ion aqueous solution, and taking solid sediments; (6) dissolving the solid sediments by using acetone, then, dropwise adding a NaOH solution for salt formation, and performing vacuum drying at low temperature, so as to obtain the sodium ferrous chlorophyllin.

Description

technical field [0001] The invention relates to the technical field of chlorophyll derivatives, in particular to a preparation technology of iron sodium chlorophyllin. Background technique [0002] Food coloring is an edible substance that improves the color and luster of food. It is divided into two types: natural coloring and artificial coloring. Synthetic food colorings are made from aniline dyes separated from coal tar. As people pay more and more attention to food safety, artificial synthetic colorings are increasingly questioned by people. Natural food colorings are pigments directly extracted from animal and plant tissues. They have the characteristics of natural color tone and high food safety, and are increasingly welcomed by people. [0003] Chlorophyll is a fat-soluble pigment that widely exists in green plants, and it is a natural pigment that is allowed to be used in my country and most countries. Modern research shows that chlorophyll has the functions of hem...
