Abstract
An object of the present invention is to provide a technique of suppressing precipitation of an anthocyanin pigment in a range other than the highly acidic range. The present invention provides an anthocyanin pigment preparation, comprising: an anthocyanin pigment; and an emulsifier, wherein the pH when the anthocyanin pigment preparation is diluted with water or dissolved in water so that a color value becomes 10 is more than 3.
Claims17
An anthocyanin pigment preparation, comprising:
- an anthocyanin pigment;
- and
- an emulsifier,
- wherein the pH when the anthocyanin pigment preparation is diluted with water or dissolved in water so that a color value becomes 10 is more than 3.
An anthocyanin pigment preparation comprising an anthocyanin pigment in a combination of an emulsifier and an alkalifying agent,
- wherein the pH when the emulsifier, the alkalifying agent, and the anthocyanin pigment are diluted with water or dissolved in water so that a color value becomes 10 is more than 3.
An agent for suppressing generation of precipitates of an anthocyanin pigment in a pH range more than a pH of 3, the agent comprising an emulsifier.
A method for suppressing generation of precipitates of an anthocyanin pigment in a pH range more than a pH of 3, the method comprising the step of bringing an anthocyanin pigment in which precipitates are not generated into contact with an emulsifier.
A method for producing an anthocyanin pigment preparation in which generation of precipitates of an anthocyanin pigment in a pH range more than a pH of 3 is suppressed, the method comprising the step of mixing an anthocyanin pigment in which precipitates are not generated with an emulsifier.
