(1) First Example A method for extracting a red pigment of a safflower, adsorbing it on powdered cellulose, and extracting the same, and a coloring agent produced by the method. First step: removing a yellow pigment component from a dried petal of a safflower. As described above, the yellow pigment component has a property of being soluble in water, and the red pigment component has a property of being insoluble in water. Therefore, the dried petals of the safflower are washed with water for several days, specifically for at least 40 hours, and the washed petals are squeezed to leave the squeezed petals, and the water is removed together with the dissolved yellow pigment component.

た溶液は、やや茶色っぽい色をしている。Second step: The red dye is taken out. The petals from which the yellow pigment component has been removed by washing with water in the first step are stirred in an alkaline solution, and the petals are squeezed to take out a solution in which the red pigment component is dissolved. Specifically, 250 g of potassium carbonate is put into 4 liters of hot water at about 40 degrees Celsius for 800 g of dried petals and stirred. At this time, potassium carbonate is p
The amount is set so that H is about 9. Alkaline solution is not limited to potassium carbonate, but in the present invention, it is mainly used as a coloring agent when it is intended to be added to food or used for medicines or cosmetics that come into direct contact with the human body, Potassium carbonate, used as The solution in which the red pigment component has been taken out at this stage has a slightly brownish color.

The solution in which the red dye component obtained in the second step is dissolved is neutralized with an acidic solution. Then, bright red of safflower is obtained. Specifically, 180 g of citric acid was added to 4 liters of the solution in which the red pigment component obtained in the second step was dissolved.
And neutralize to pH 6.5-7. And
The red dye that has settled out of the solution is removed.

Since the yellow pigment remains in the solution obtained in the third step, the red pigment is adsorbed on cellulose having relatively large particles to remove the yellow pigment. Further, returning to the first step, washing is carried out with water to remove a yellow component, and then, in the second step, an alkaline solution such as potassium carbonate is added to make a strong alkaline solution, and then the acidic solution such as citric acid is used. Neutralizes and develops a red color. If this repetition step is further repeated, a red pigment having higher purity can be obtained.

Cellulose is mixed into the solution obtained by extracting the red pigment obtained in the fourth step, and the red pigment is adhered to the cellulose. The red pigment adhered to the cellulose is precipitated and filtered. At this time, a chemical fiber to which the red pigment does not adhere is used as the filtering material. After filtration, the supernatant liquid is removed to give a paste-like colorant slightly containing water. Drying completely without moisture gives a powdery colorant. As described above, since the red colorant attached to cellulose has high heat resistance and light resistance, it is suitable for use in materials that are heated and heated.

First step: yellow from a dried safflower petal The pigment component is removed. Second step: take out the red dye. Third step: neutralize the solution in which the red pigment component is dissolved. Fourth step: Repeat to increase purity. The above four steps are the same as in the first embodiment.

In the first step, the petals are washed with water to remove the yellow pigment component, the petals from which the yellow pigment component has been removed are stirred in an alkaline solution in the second step, and the petals are squeezed to dissolve the red pigment component. Remove the solution. Therefore, the remaining petals are bleached. The decolored petals are squeezed well, rapidly frozen, dried at 50 ° C. under vacuum, and pulverized to 3 to 5 microns by a mill.

The decolorized petal powder obtained in the fifth step of freeze-drying is colored with the solution of the red pigment obtained in the fourth step. At this time, since the petals after the second step remain alkaline with potassium carbonate, 2 liters of water or hot water and 50 g of citric acid are added, neutralized, and further washed with water to extract a red pigment. By returning the petals to bleached petals without using cellulose, the crude drug components originally possessed by safflower can be used as they are.

Dextrin (polysaccharide) is mixed into the solution obtained by extracting the red pigment obtained in the fourth step, and the mixture is stirred, rapidly frozen, then pressed at 50 degrees Celsius, vacuum dried, and reduced to 3 to 5 microns by a mill. Powderize. The colorant obtained in the fifth step is transparent and bright red. However, the coloring agent extracted as a powder by the freeze-drying does not have high heat resistance, and when exposed to light, fades in several hours, so that the heat resistance can be increased in the next sixth step.
