Zusammenfassung: | To provide a gardenia pigment formulation to which acid resistance is added, a gardenia blue pigment formulation, and a method for adding acid resistance.SOLUTION: Ghatti gum and/or gum arabic are added to a gardenia pigment formulation containing a gardenia red pigment and a gardenia blue pigment and having color valency of 5 to 500. Preferably the ghatti gum and/or gum arabic are added so that content of the ghatti gum or gum arabic in the gardenia pigment formulation satisfies the following formulae. (Formula 1) ghatti gum content (mass%)≥(color valency of the gardenia pigment formulation)×0.005, (Formula 2) gum arabic content (mass%)≥(color valency of the gardenia pigment formulation)×0.2, (Formula 3) ghatti gum content (mass%)≥(color valency of the gardenia pigment formulation)×0.005×(α/(α+0.025β)), wherein α means ghatti gum content (mass%) in the gardenia pigment formulation and β means gum arabic content (mass%) in the gardenia pigment formulation.SELECTED DRAWING: Figure 2
【課題】耐酸性が付与されたクチナシ赤色素製剤及びクチナシ青色素製剤、及び耐酸性を付与する方法を提供する。【解決手段】クチナシ赤色素又はクチナシ青色素を含有し、色価が5以上500以下であるクチナシ色素製剤に、ガティガム及び/又はアラビアガムを添加する。好ましくは、クチナシ色素製剤におけるガティガム又はアラビアガムの含量が、下記式を満たすように、ガティガム及び/又はアラビアガムを添加する;(式1)ガティガム含量(質量%)≧(クチナシ色素製剤の色価)×0.005、(式2)アラビアガム含量(質量%)≧(クチナシ色素製剤の色価)×0.2、(式3)ガティガム含量(質量%)≧(クチナシ色素製剤の色価)×0.005×(α/(α+0.025β))、ここで、αはクチナシ色素製剤におけるガティガム含量(質量%)を、βはクチナシ色素製剤におけるアラビアガム含量(質量%)を意味する。【選択図】図2 |
