Blue colorant derived from
The present invention provides a method to make a blue colorant as a liquid and as a powder, wherein the blue colorant is derived from unprocessed raw juice obtained from Genipa americana fruit pulp, and wherein said raw juice is mixed with glycine (liquid) or with glycine plus starch (powder). Except for an additional step of warming up the juice-glycine mix, and in the case of the powder further dehydration of the juice-glycine-starch remix, no further steps are required to make a temperature and PH stable blue colorant which may be applied in textile, pharmaceutical, food, cosmetics, and other industries.
1. A method of manufacturing a colorant pH-stable blue comprising:
A. Peeling off a Genipa americana fruit from its skin, wherein said skin is discarded, and wherein said fruit without skin is Genipa americana fruit pulp;
B. Obtaining raw liquid juice from the Genipa americana fruit pulp;
C. Mixing the raw liquid juice with glycine; and,
D. Warming up the raw liquid juice mixed with glycine for a determined period of time.
2. The method of claim 1 , wherein obtaining the raw liquid juice from the Genipa americana skinless fruit comprises:
a. Grinding the Genipa americana fruit pulp;
b. Compressing the grinded Genipa americana fruit pulp against a mesh, wherein major solids are retained by said mesh, and wherein raw liquid juice goes throughout said mesh.
3. The method of claim 1 , wherein mixing the raw liquid juice with glycine comprises mixing at least 0.2 grams of glycine per 100 milliliters of raw liquid juice.
4. The method of claim 3 , wherein mixing the raw liquid juice with glycine comprises mixing between 0.2 grams and 1.6 grams of glycine per 100 milliliters of raw liquid juice.
5. The method of claim 1 , wherein said method further comprises:
E. Adding starch to the previously warmed up mix of the raw liquid juice-glycine, and remixing, wherein said remixing results in an raw liquid juice-glycine-starch remix;
F. Dehydrating the raw liquid juice-glycine-starch remix, wherein dehydrating said remix comprises injecting the remix into a heated chamber by way of an atomizer; wherein the atomizer has the effect of converting the remix into small liquid remix droplets, wherein the chamber heat vaporizes water from said droplets, wherein vaporizing the water from said droplets results in low density particles and high density particles, wherein the high density particles precipitate to the chamber bottom and wherein the low density particles are aspirated with a vacuum, and wherein the aspirated low density particles form dried colorant powder.
6. The method of claim 1 , wherein said method further comprises:
e. Adding starch to the previously warmed up mix of the raw liquid juice-glycine, and remixing, wherein said remixing results in an raw liquid juice-glycine-starch remix;
f. Dehydrating the raw liquid juice-glycine-starch remix to form a powder.
7. The method of claim 6 , wherein said dehydrating comprises lyophilization.
8. A pH-stable blue liquid colorant prepared by the method of claim 1 .
9. The liquid colorant of claim 8 , wherein the mix of raw liquid juice and glycine comprises at least 0.2 grams of glycine per 100 milliliters of raw liquid juice.
10. The liquid colorant of claim 9 , wherein the mix of raw liquid juice and glycine comprises between 0.2 grams and 1.6 grams of glycine per 100 milliliters of raw liquid juice.
11. A pH-stable blue powder colorant prepared by the method of claim 6 .
12. The powder colorant of claim 11 , wherein the dehydrated mix is derived from a premix of raw liquid juice and glycine, wherein said premix comprises at least 0.2 grams of glycine per 100 milliliters of raw liquid juice.
13. The powder colorant of claim 12 , wherein the dehydrated mix is derived from a premix of raw liquid juice and glycine, wherein said premix comprises between 0.2 grams and 1.6 grams of glycine per 100 milliliters of raw liquid juice.
