Description

  The present invention relates to a paprika dye and a method for producing the same.

  Paprika pigment is an oily pigment composed mainly of a fatty acid ester of capsanthin, which is a kind of carotenoid obtained from the fruit of Capsicum annuum Linne. Paprika pigments are widely used in foods and the like as red colorants derived from natural materials.

  Paprika dyes tend to fade relatively easily under the influence of light. As a method for suppressing fading of paprika pigment due to light, in general, extraction tocopherol is added, and a method of adding Rafu hemp extract as a fading inhibitor is known (Patent Literature). 1). However, these methods do not suppress fading of the paprika dye itself, and are not always satisfactory in practice.

  In addition, the paprika pigment is preferred to have a strong reddish color, but the color of the paprika pigment depends on the quality of the paprika fruit that is the raw material (for example, paprika fruit variety, production area, production method, production time, etc.) It depends heavily. For this reason, it is difficult to stably supply or obtain a paprika dye having a strong reddish color.

  In order to solve such a problem, several methods are known in which a paprika pigment is formulated with a specific material, or a specific form of the formulation is used to obtain a strong reddish color tone (Patent Document 2). And 3). However, these methods also do not improve the color tone of the paprika dye itself, and are not necessarily satisfactory in practice.

  On the other hand, paprika pigments are oil-soluble and are difficult to use for water-based foods and beverages as they are. Therefore, in order to impart water dispersibility to the paprika pigment, preparation of an emulsified preparation of the paprika pigment has been performed. However, such a form of preparation may lose its commercial value due to destruction of emulsification under the influence of heat or the like during storage.

  As a method for improving the emulsion stability of an emulsified preparation of paprika pigment, a method using a paprika pigment washed with water or a mixed solution of water and a lower aliphatic alcohol is known (Patent Document 4). However, this method cannot solve all of the problems described above.

  An object of the present invention is to provide a paprika dye that can produce a paprika dye preparation that is inhibited from fading by light, has a strong reddish color tone, and has high emulsion stability.

  As a result of intensive studies to solve the above problems, the present inventors have found that the above-mentioned problems can be solved by a novel paprika dye characterized by the absorbance curve of the UV-visible absorption spectrum. Invented the invention.

That is, the present invention comprises the following [1] to [6].
[1] The light absorption area S of the portion surrounded by the curve in the wavelength range of 640 to 685 nm in the absorbance curve of the UV-visible absorption spectrum and the straight line connecting the two points of wavelength 640 nm and 685 nm in the absorbance curve is expressed by the following formula (1). A paprika pigment characterized by filling.
Formula (1): S × 1500 / color value of paprika pigment (E ^10% _{1 cm} ) ≦ 0.2
[2] The paprika pigment according to [1], wherein the phosphorus content P (mg / 100 g) satisfies the following formula (2).
Formula (2): P × 1500 / color value of paprika pigment (E ^10% _{1 cm} ) ≦ 60
[3] A paprika dye preparation comprising the paprika dye described in [1] or [2].
[4] The paprika pigment preparation according to the above [3], which is an oil-in-water emulsion formulation.
[5] A method for producing a paprika dye wherein the absorption area S of the ultraviolet-visible absorption spectrum satisfies the following formula (1), wherein the activated clay is removed after contacting the paprika dye raw material with the activated clay.
Formula (1): S × 1500 / color value of paprika pigment (E ^10% _{1 cm} ) ≦ 0.2
(In the formula, S represents the light absorption area of the portion surrounded by the curve in the wavelength range of 640 to 685 nm in the absorbance curve of the UV-visible absorption spectrum and the straight line connecting the two points of wavelength 640 nm and 685 nm on the absorbance curve.)
[6] After contacting the paprika pigment raw material with the activated clay, the activated clay is removed, and the absorption area S of the UV-visible absorption spectrum and the phosphorus content P (mg / 100 g) are expressed by the following formula ( A method for producing a paprika dye satisfying 1) and (2).
Formula (1): S × 1500 / color value of paprika pigment (E ^10% _{1 cm} ) ≦ 0.2
Formula (2): P × 1500 / color value of paprika pigment (E ^10% _{1 cm} ) ≦ 60
(In the formula, S represents the light absorption area of the portion surrounded by the curve in the wavelength range of 640 to 685 nm in the absorbance curve of the UV-visible absorption spectrum and the straight line connecting the two points of wavelength 640 nm and 685 nm on the absorbance curve.)

Formula (1): S × 1500 / color value of paprika dye (E ^10% _{1 cm} ) ≦ 0.2 (preferably 0.15, more preferably 0.1)

Here, since the absorbance in the ultraviolet-visible absorption spectrum is proportional to the color value of the paprika dye, the light absorption area affects the color value. Therefore, in the formula (1), the light absorption area S is multiplied by 1500 and divided by the color value of the paprika dye, thereby converting the light absorption area of the paprika dye having a color value (E ^10% _{1 cm} ) of 1500.

The area of the part surrounded by the straight line connecting the two points is calculated as the light absorption area S. For the calculation, an area calculation table (divisor 1; baseline is not set to zero) of spectrophotometer data processing software (UVProbe (Ver 2.21); manufactured by Shimadzu Corporation) is used.
