Carotene, gardenia yellow pigment (crocin), paprika pigment (carotenoid), beet red (betacyan type), red malt red pigment (azaphylon type), safflower pigment (chalcone type), red cabbage pigment, perilla pigment, grape pigment (anthocyanin type) ) Etc. are known. However, it is recognized that these dyes are often faded when exposed to light rays such as ultraviolet rays, visible rays, and infrared rays during storage. Therefore,
In order to maintain the quality and color of processed foods that use colorants, UV blocking packaging materials and colored packaging materials are used, but pigments that are photo-deteriorated by rays other than UV rays even when using UV blocking packaging materials. The effect is not always perfect. Further, the use of a colored packaging material has a drawback that the contents are difficult to see, and at present, it is only used for laver, delicacy, snacks and the like.

いた。Lactoferrins usually have the ability to chelate 2 iron atoms per molecule, which is equivalent to binding 14 mg of iron per gram of lactoferrins. However, the iron-lactoferrin used in the present invention is
By subjecting lactoferrins to a specific treatment, at least 3 iron atoms can be stably retained per molecule of lactoferrins. By doing so, a large amount of iron can be bound to lactoferrin. Such iron-lactoferrin is conventionally known. For example, iron-lactoferrin obtained by dissolving lactoferrin in water and adding an iron compound to this to react lactoferrin with iron to leave the iron in the solution in a non-free state [JP-A-4-41067], Lactoferrin powder that stably holds iron obtained by adding an iron salt to a lactoferrin solution and adding an alkali to raise the pH of the solution
7-17825], a heat-resistant iron-lactoferrin conjugate in which iron is bound to an amino group of lactoferrin through a bicarbonate ion [JP-A-6-239900], or a solution containing carbonic acid, bicarbonate and lactoferrin Carbonic acid and / or bicarbonate-iron-lactoferrin complex [Japanese Patent Application No. 7-86023] obtained by mixing a solution containing iron in the above is known. Any of these can be used for the iron-lactoferrin in the present invention. Iron-lactoferrin is a state in which iron and lactoferrin are bound, and iron and lactoferrin may be bound directly, or may be in a state bound via other substances, So-called iron may be used if it does not exist in an ionic state. In particular, an iron-lactoferrin conjugate in which carbonic acid and / or bicarbonate is bound to lactoferrin [JP-A-6-239900] or an iron-lactoferrin complex [Japanese Patent Application No. 7-86023] can be used. preferable. The characteristic of the iron-lactoferrin complex as a dye is that there is no clear peak in the visible light band (700 nm to 300 nm). Spectrophotometer for iron-lactoferrin complex
(Hitachi U-2000) Chart is shown in Fig. 1. This iron-lactoferrin complex was prepared by dissolving the lactoferrin complex of Reference Example 2 in water to give a 0.5% solution and used as a sample.

ものを使用することもできる。This iron-lactoferrin has the property of not fading even when exposed to light rays such as ultraviolet rays, visible rays, infrared rays, and the like, and is also excellent in heat resistance and pH stability. In the iron-lactoferrin conjugate or the iron-lactoferrin complex that is not bound via carbonic acid and / or bicarbonate, iron is not completely bound to lactoferrin, so after removing unbound iron, It is desirable to use. Examples of the lactoferrin that can be used when producing the iron-lactoferrin used in the present invention include lactoferrin separated from a secretory fluid such as mammalian milk, but it is separated from blood or organs. Transferrin and ovotransferrin separated from eggs and the like have similar properties and can be used in the same manner as lactoferrins. Also, lactoferrins need not be completely isolated,
It may contain other components. Furthermore, it is also possible to use lactoferrins produced from microorganisms, animal cells, transgenic animals, etc. by genetic engineering. It is also possible to use lactoferrins hydrolyzed with an enzyme such as trypsin, pepsin, chymotrypsin.

The method of using the red colorant of the present invention is not particularly limited and may be the same as a normal colorant. The red colorant of the present invention can be used not only for coloring foods and drinks but also as a red colorant in various fields. In particular, since iron-lactoferrin is water-soluble, it can be used by coloring powders such as margarine and jelly in the range of 0.001 to 1% by force directly mixing them with powder or by adding them as an aqueous solution. preferable.

他あらゆる分野で利用することができる。EFFECTS OF THE INVENTION The red colorant of the present invention does not fade when the active ingredient, iron-lactoferrin, is exposed to light such as ultraviolet rays, visible rays, infrared rays, etc., and does not discolor when mixed with food ingredients. Moreover, since iron-lactoferrin itself is non-toxic, it can be used as a red colorant in foods and drinks, their packaging materials, medicines and all other fields.
