Abstract

The invention discloses a method for preparing and extracting iron chlorophyll and the prepared iron chlorophyll. The method includes the following steps: (1) selecting suaeda salsa in the growing period, taking the young stems and leaves, washing and dehydrating; (2) smashing the dehydrated stems and leaves of the suaeda salsa into slurry, adding low-temperature cellulase into the slurry, stirring uniformly, and performing enzymolysis for 8-20 hours; (3) adding an extracting solvent, vibrating and extracting for 0.5-1 hour in a vibrating device, wherein the extraction is carried out twice, separating solid from liquid to obtain a chlorophyll extract; (4) dropwise adding a NaOH solution into the extract for saponification, and then carrying out vacuum rectification, extracting using petroleum ether, and taking the lower-layer sodium chlorophyllin solution; (5) adjusting the pH value to be 2-3 using chlorhydric acid, dropwise adding a ferrous ion aqueous solution, taking the solid precipitate, and vacuum drying at low temperature to obtain the iron chlorophyll. The iron chlorophyll prepared by the invention can be used to prepare sodium ferrous chlorophyllin, sodium zinc chlorophyllin and other derivatives, and the application is wide.

Description

technical field [0001] The invention relates to the technical field of deep processing of Suaeda salsa, in particular to a technology for preparing chlorophyll derivatives using Suaeda salsa as a raw material. 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...
