JP2000125781A - Production of white egg having high vitamin k2 content - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain the subject food having a high transfer ratio of vitamin K3 to vitamin K2 in egg, vitamin K2 in a high concentration and high safety without individual difference by feeding a vitamin K3-containing feed to chickens for gathering white eggs and raising the chickens. SOLUTION: A feed containing 10-100 ppm, preferably 20-100 ppm vitamin K3 is fed to chickens for gathering white eggs and the chickens are raised. For example, menadione sodium hydrogensulfite, menadione bisulfite dimethylpyrimidinol, etc., may be cited as vitamin K3. Maria, TX-35, XL LINK, etc., may be cited as the chickens for gathering white eggs. When the objective feed is fed to the chickens, since most vitamin K3 is changed into vitamin K2 in chicken body and is transferred to white eggs as vitamin K2 in a high ratio, the objective feed is supplied for >=14 days.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a method of producing white egg containing vitamin K ₂ in a high concentration.

[0002]

2. Description of the Related Art Vitamin K has an action of promoting the synthesis of prothrombin in the liver, and vitamin K deficiency causes a decrease in blood coagulation ability. Vitamin K is said to be contained in pig liver and cabbage, but its content varies from individual to individual, and it is difficult to ingest a sufficient amount from these natural foods.

[0003] On the other hand, shows the highest activity in human body among the vitamin K is vitamin K _2, vitamin K
₂ is rather expensive compared to vitamin K _3, there is a financial problem to ingest directly. Also, vitamin K
₃ is the most expensive, but has a strong vitamin K action compared to vitamin K ₁ and vitamin K _2, there is a toxicity problem of liver damage.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for producing a highly safe food containing vitamin K ₂ at a high concentration without any individual difference.

[0005]

Means for Solving the Problems Accordingly, the present inventors have:
When the fed vitamin K ₃ poultry which changes to vitamin K _2, that vitamin K ₂ moves in poultry eggs, also when the fed a vitamin K ₁ part changes to vitamin K _2, poultry eggs vitamin K ₁ and vitamin K ₂ is found to migrate, and patent applications previously in (KOKOKU 7-1636
No. 5). Furthermore, as a result of further study, the transfer rate of vitamin K ₂ to eggs when vitamin K ₃ was fed was higher in the case of white egg laying chickens than in the case of brown egg laying chickens. It was found that the feeding of vitamin K ₃ was particularly advantageous for the production of white chicken eggs high in vitamin K ₂ and completed the present invention.

Namely, the present invention provides a vitamin K ₂ method of producing a high content whitish eggs, which comprises rearing giving feed to 10~100ppm vitamins K ₃ in white egg laying chicken Things.

[0007]

DETAILED DESCRIPTION OF THE INVENTION In the present invention, vitamin K ₃
It is necessary to feed a feed containing 10 to 100 ppm. The required amount of vitamin K in humans is 6 per adult per day
It is said to be 0 μg, and since osteoporosis patients and the like need more vitamin K, the amount of vitamin K normally lacking in one day is said to be 30 to 60 μg. Considering this point, the content of vitamin K _{3 in} the feed is 10p
If it is less than pm, vitamin K ₂ cannot be sufficiently transferred into white eggs, and even if a human eats 1 to 3 eggs per day, a sufficient amount of vitamin K ₂ cannot be taken.
On the other hand, if the content of vitamin K ₃ exceeds 100 ppm, the rate of change to vitamin K ₂ and transfer to eggs reaches a plateau, which is not preferable in terms of economy. Further, more preferably the vitamin K ₃ concentration in the feed is 20 to 100 ppm.

[0008] As vitamin K ₃ is menadione sodium bisulfite, menadione bisulfite dimethyl pyrimidinone Nord, and the like.

[0009] Payroll method K ₃ is added vitamin K ₃ to a concentration of the normal white egg laying for in poultry feed, the resultant feed a may be supplied by conventional means.

The chicken species for white egg collection of the present invention include:
For example, TX-35, Maria, Excellink and the like can be mentioned.

When a diet containing vitamin K ₃ is fed to a white egg-laying hen according to the method of the present invention, most of the vitamin K ₃ is changed into vitamin K ₂ in the chicken body, and vitamin K ₃ is fed. proceeds at a high rate in white in eggs as vitamin K ₂ after week. Then, even if the white egg collecting hen continues to lay eggs every day, the content of vitamin K _{2 in} the eggs does not change if the feed is continuously provided every day. Thus, vitamin K ₃ containing feed may be salary more than 14 days.

[0012]

EXAMPLES The present invention will be further described with reference to examples, but the present invention is not limited thereto.

Example 1 A group of 10 chickens of each breed for egg collection was used and fed feeds shown in Table 1 to which vitamin K ₃ (sodium menadione bisulfite) was added at a concentration of 50 ppm. Vitamin K ₂ concentration in the yolk of eggs of each chicken species collected 17 days after feeding was measured by high performance liquid chromatography. The result is shown in FIG.

[0014]

[Table 1]

As a result, as apparent from FIG. 1, when a feed containing 50 ppm of vitamin K ₃ is added, the vitamin K ₂ concentration is significantly higher in white eggs than in brown eggs. In addition, about 6 eggs (raw eggs)
0 g and the egg yolk is about 15 g per egg, so eating one egg produced by the method of the present invention results in ingestion of about 30 μg of vitamin K ₂ .

EXAMPLE 2 10 chickens per group of TX-35 were used as chickens for collecting white eggs.
Vitamin K was added to the feed shown in Table 1._Three(Menadionic acid sulfite
Sodium hydrogen oxyacid) at each concentration of 10 to 200 ppm
Was paid. Eggs of each group collected 3 weeks after feeding
Vitamin K in egg yolk _TwoHigh performance liquid chromatography for concentration
-Measured by Table 2 shows the results.

[0017]

[Table 2]

According to the above results, vitamin K _{3 is} contained in the feed.
It can be seen that when 10 to 100 ppm is added, the vitamin K ₂ concentration in the yolk increases in a dose-dependent manner, but thereafter reaches a plateau.

[0019]

According to the present invention, by using an inexpensive vitamin K _3, it is possible to obtain a white egg containing high active vitamin K ₂ in a large amount in the body, white obtained in the present invention Eggs are extremely useful as a food for preventing vitamin K deficiency.
