Problems solved by technology

[0009] However, in the technologies of patent documents 1 to 5, the obtained gardenia blue pigment is still reddish, and the color tone is still unsatisfactory, and it is impossible to produce the same bright and reduced color as edible blue No. 1 and spirulina pigment. A reddish gardenia blue pigment with a bluish tinge

Embodiment 2-1～2-5

[0159] Gardenia blue dyes were produced in the same manner as in Test Example 1 above, except that the soybean peptides shown in Table 3 were used for the reaction under the condition of not supplying oxygen.

[0160] 2. Determination of hue of gardenia blue pigment

[0161] The hue of the obtained gardenia blue pigment was measured under the same conditions as in Test Example 1 above. The obtained results are shown in Table 3. From this result, it was confirmed that when the predetermined peptide and genipin were reacted under the condition of not supplying air and then reacted under the condition of supplying air, the lower the free amino acid content of the peptide used, the more panacea could be obtained. A gardenia blue pigment with a good tone that suppresses redness.

Embodiment 3-1～3-3

[0166] 1. Manufacture of gardenia blue pigment (using a fermenter) (Examples 3-1 to 3-3 and Comparative Example 3-1)

[0167] As the added peptide, soybean peptide (Hinute AM, Fuji Oil Co., Ltd.) was used, and the reaction time under the condition of not supplying oxygen was changed to 0 hour (Comparative Example 3), 4 hours (Example 3-1), The gardenia blue dye was produced by the method similar to the said Experimental Example 1 except 5 hours (Example 3-2) and 22 hours (Example 3-3).

Abstract

The purpose of the present invention is to provide a gardenia blue pigment which offers a bright, fresh blue color tone having reduced redness, and a production method for the same. The gardenia blue pigment which offers a bright, fresh blue color tone having reduced redness is obtained by carrying out a first step in which genipin and at least one peptide selected from the group consisting of soybean peptides, sesame peptides, and rice peptides are reacted in a solvent without the presence of an oxygen-containing gas supply, and a second step in which a reaction liquid obtained in the first step is processed under an oxygen-containing gas supply.

Description

technical field [0001] The present invention relates to gardenia blue pigments exhibiting bright blue hues with reduced redness. Moreover, this invention relates to the manufacturing method of this gardenia blue pigment. Background technique [0002] Conventionally, food blue No. 1 (2-(bis{4-[N-ethyl-N-(3-sulfophenylmethyl)amino]benzene Base} methyl onium base (methyliumyl) disodium benzenesulfonate), spirulina pigment, gardenia blue pigment, etc. Food blue No. 1 and spirulina pigments are bright, less reddened, highly yellowed, vivid blue pigments, and have the characteristic of having a vivid blue hue. However, since Food Blue No. 1 is a synthetic coloring agent, there is a tendency to avoid its use as consumers' awareness of food safety increases. In addition, although the spirulina pigment is a natural pigment, it has the disadvantages of being easily discolored by heat and being expensive. On the other hand, gardenia blue pigment is a natural pigment, which also has...
