Embodiment 1

[0024] Dissolve 2.1g of carminic acid in 20ml of water, and add 3.3g of whey protein into 30ml of water, heat and stir to dissolve. Then the carmine solution and raise the temperature to 85-95°C, slowly add the whey protein solution. Stir the reaction for 1 hour, the solution produces a large amount of precipitation, centrifuge at 4000 rpm for 10 minutes, collect the solid, wash the solid once with deionized water, dry the collected solid under vacuum at 60°C, and crush it to 100-200 mesh to obtain red rouge Insect lake, the prepared cochineal lake has no obvious color change between pH 4.0 and 7.0, and is red.

Embodiment 2

[0026] The present embodiment provides a kind of preparation method of the carmine lake that does not contain aluminum salt, comprises the following steps:

[0027] (1) Preparation of cochineal pigment solution: stirring and dissolving cochineal pigment with a purity of more than 90% in deionized water, the mass ratio of cochineal pigment to deionized water is 1:5;

[0028] (2) Prepare whey protein solution: dissolve whey protein in deionized water, and the mass ratio of whey protein to deionized water is 1:5;

[0029] (3) The temperature of the carmine pigment solution was raised to 85°C, and the whey protein solution was slowly added therein, and stirred for 2 hours; wherein the volume ratio of the cochineal pigment solution to the whey protein solution was 1:3.

[0030] (4) The reaction solution was naturally cooled to room temperature, filtered by suction, the solid was collected, dried in vacuum at 50°C, and crushed to 100-200 mesh to obtain cochineal red lake without alu...

Embodiment 3

[0033] The present embodiment provides a kind of preparation method of the carmine lake that does not contain aluminum salt, comprises the following steps:

[0034] (1) Preparation of cochineal pigment solution: stirring and dissolving cochineal pigment with a purity of more than 90% in deionized water, the mass ratio of cochineal pigment to deionized water is 1:8;

[0035] (2) Prepare whey protein solution: dissolve whey protein in deionized water, and the mass ratio of whey protein to deionized water is 1:8;

[0036] (3) The temperature of the cochineal red pigment solution was raised to 90° C., and the whey protein solution was slowly added therein, and stirred for 1 hour. The volume ratio of the cochineal red pigment solution to the whey protein solution was 1:2.5.

[0037] (4) The reaction solution was cooled down to room temperature naturally, filtered through plate and frame, the solid was collected, dried in vacuum at 60°C, and crushed to 100-200 mesh to obtain cochine...

Abstract

The invention relates to aluminum-salt-free cochineal lake and a preparation method of the cochineal lake. The preparation method comprises the following steps: (1) preparing a cochineal pigment solution; (2) preparing a whey protein solution; (3) stirring and reacting the cochineal red pigment solution and the whey protein solution; and (4) cooling the reaction liquid to room temperature, filtering or centrifuging, collecting the solid, and drying to obtain the aluminum-salt-free cochineal lake. Compared with the prior art, the method has the advantages that the process is simple and easy to implement, the operation is simple, the cost is low, aluminum salt is not used, calcium salt is not additionally added, calcium ions in protein are directly utilized to form chelation to obtain the cochineal lake which is good in stability; in addition, compared with a lake prepared by directly adopting a coccinic acid primary extracting solution, the yield of the disclosed cochineal lake is greatly improved, the cochineal protein content is low, and anaphylactic reaction is not easily caused.

Description

technical field [0001] The invention belongs to the field of natural pigment preparation, in particular to an aluminum-salt-free carmine lake and a preparation method thereof. Background technique [0002] Carmine is an anthraquinone natural pigment extracted from cochineal. Depending on the pH value, the color range of carminic acid colorant can range from orange to red to purple. It is used in food, cosmetics, medicine and textiles. It is an excellent coloring agent and the only natural coloring that FDA allows for both food, medicine and cosmetics. However, due to the wide fluctuation range of the maximum wavelength of the color of carminic acid products under different pH conditions, the application field of carminic acid is limited. In order to solve this problem, patents CN101061185A, CN 101461513A, and CN101475756A have prepared aluminum calcium carminate lake, which is a chelated lake compound combined with carminic acid and aluminum ions and calcium ions. The prod...
