However, these external skin preparations are less stable than those containing vitamin C, do not have sufficient whitening effects like those containing colloidal sulfur, and have side effects like those containing hydroquinone. It has its drawbacks and cannot be said to be fully satisfactory.

Recently, a cosmetic containing kojic acid or a fatty acid ester thereof has been invented, focusing on the fact that kojic acid or a fatty acid ester thereof has a whitening effect and an effect of preventing pigmentation after sunburn. However, since this cosmetic is applied externally to the skin like other cosmetics, it cannot be used by people who are allergic to the base of the cosmetic. Also,
Men and children do not have the habit of wearing makeup, so they feel reluctant to use it and find it difficult to use it. Furthermore, since cosmetics adhere to the skin, there is a limit to the amount of the adherent, and therefore, there is a limit to the whitening effect and the effect of preventing pigmentation after sunburn.

An object of the present invention is to provide an excellent whitening food that does not have the drawbacks of conventional products as described above.

The present inventor has discovered that kojic acid or its fatty acid ester has a whitening effect and an antipigmentation effect even when consumed or eaten, and is completely harmless to the human body.
They discovered that when mixed with food, it has high acid resistance, alkali resistance, light and heat stability, and good storage stability.

The present invention was completed based on the above discovery, and is a whitening food product characterized by containing a whitening agent consisting of kojic acid or its fatty acid ester.

The whitening food of the present invention exhibits an excellent whitening effect and antipigmentation effect when consumed, and is safe without any unfavorable side effects on the human body.

Furthermore, a large amount of kojic acid or its fatty acid ester can be stably blended, and the storage stability is good.

Furthermore, it can be used by a wide range of people, including people who are allergic to cosmetic bases, men, and children.

The kojic acid used in the present invention has the following structural formula.

It is a water-soluble compound and is a colorless needle-like crystal with a molecular weight of 142. This is mainly due to Aspergillus oryza,
Aspergillus frapas, Aspergillus tamari,
It is cultured and produced from various carbohydrate compounds by Albergillus fungi such as Anubergillus ventii, Aspergillus nidovrans, and Aspergillus candidas.

Or chemically synthesized.

M9. Kojic acid fatty acid varnish f used in the present invention
For example, modiesters or diesters with saturated fatty acids such as myristic acid, valmitic acid, stearic acid, isostearic acid, modiesters or diesters with unsaturated fatty acids such as linoleic acid, lylunic acid, oleic acid, etc./L
/ or a diester of saturated fatty acids and unsaturated fatty acids.

The amount of kojic acid or its fatty acid esthetic μ contained in the whitening food of the present invention is o', 0/N2o% by weight, preferably 0/-10% by weight, and is determined depending on the amount of food consumed per food.

Next, examples of the present invention will be described.

Example/Tablet confectionery - The tablet confectionery of this example is obtained by mixing the primary raw materials in a ladle, granulating this and compressing it into tablets, and contains 0.2% kojic acid.

Tablet confectionery of Example/Tablet confectionery of Comparative Example, respectively.

Ages that are worried about age spots, freckles, and dark skin, 2! - A test was conducted to confirm the effectiveness of the present invention by asking a 30-year-old general woman with a 2S name to sample 783 tablets for 3 months. The test results showed that each subject had smooth skin.

■Deep spots, freckles, and ■Degree of fair skin color change were self-evaluated. The results are shown in the table below.

This indicates that kojic acid is responsible for tyrosinase activity in the skin.
It is recognized that it has a whitening effect and an antipigmentation effect by inhibiting the production of melanin.

Example 1 The candy of this example was mixed and dissolved in 13.0 parts by weight of powdered Trubit and 0 parts by weight of citric acid in water/t ¥, and the mixture was depressurized in a vacuum pan. Heat the cotton under the stove until the moisture content is 2~S%, then transfer it to a cooling plate, add an appropriate amount of fragrance, food coloring, and kojic acid 02, and cool to a temperature of about 2000 ml. , which is molded using a roller or stamping machine.

Example 3 Soft capsule-shaped food The soft capsule-shaped food of this example was prepared by heating and dissolving parts of beeswax/IAO and safflower oil, and mixing them uniformly with stirring. ``When CK was reached, 02 parts by weight of kojic acid was added and cooled to 30'O.
This was pulverized in a colloid mill, filtered, and defoamed in a vacuum tank to obtain a semi-finished product. This semi-finished product was coated with gelatin soft capsules and dried.
