BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high concentration zeaxanthin-containing poultry egg obtained by administering poultry feed containing a spirulina algae body to poultry and raising the poultry, and a method for obtaining the poultry egg.

[0002]

2. Description of the Related Art Spirulina has recently been used as a dietary supplement because it contains abundant proteins, various vitamins, minerals, and vegetable pigments and has a high digestion and absorption rate. Nos. 21355 and 61-146173 have been reported.
Japanese Patent Application Laid-Open No. 53-75095 discloses that spirulina is useful as a feed for red fish and a method for deepening red fish using the feed.

[0003] Various physiological studies have been conducted on the physiological action of spirulina itself, for example, cholesterol lowering action (Nu).

[0004] On the other hand, in recent years, some of the functional ingredients (eg, iodine, DHA / EPA, β-carotene, astaxanthin, α- There is a special chicken egg obtained by adding and containing linolenic acid, vitamin D, etc. and raising poultry, and is on the market as a high value-added chicken egg.

[0005] In particular, the market price of chicken eggs has been sluggish for the past 25 years, and the development of special chicken eggs with higher added value has been demanded. From the viewpoint of disease prevention, functional ingredients have been added to general foods. As the development of so-called functional foods, fortified eggs with enhanced iodine egg, such as EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), α-linolenic acid, vitamin DE, β-carotene, etc. It was developed and now accounts for about 5% of egg production.

Japanese Patent Application Laid-Open No. 6-153813 discloses an example of using Spirulina algae as a chicken feed.
This is a method of utilizing β-carotene in Dunaliella algae as an adjuvant for accumulating it in egg yolk. In addition, zeaxanthin has been known to have an antioxidant effect and a precursor of vitamin A, and has been known to be nutritionally and physiologically significant, but recently has a particularly excellent carcinoid-preventing effect among carotenoids. Thus, easy acquisition and use of zeaxanthin have been expected.

SUMMARY OF THE INVENTION An object of the present invention is to provide high-concentration zeaxanthin-containing poultry eggs which are useful as foodstuffs that can easily extract zeaxanthin, which has great nutritional and physiological meanings, It is to provide as a method of obtaining poultry eggs.

[0008]

Means for Solving the Problems The present inventors have developed a nutritional
For the purpose of accumulating zeaxanthin having a large physiological meaning in poultry eggs, as a result of intensive studies on various natural product-containing feeds, a feed containing 0.5% by weight or more of Spirulina algae was administered to a laying hen, for example. , The amount of zeaxanthin in the egg yolk of a normal chicken (200 to 300 μg / 100
It has been found that g) can be increased three times or more, and the present invention has been completed.

That is, the present invention relates to a high-concentration zeaxanthin-containing poultry egg obtained by administering and breeding a poultry feed containing 0.5% by weight or more of Spirulina algae, 0.5% by weight of Spirulina algae. % Of a poultry feed containing at least zeaxanthin by administering a poultry feed containing at least 10% to the poultry and raising the poultry,

The high-concentration zeaxanthin-containing poultry egg according to the above-mentioned, wherein the Spirulina algae used contains at least 50 mg of zeaxanthin in 100 g of the Spirulina algae, 50 g of zeaxanthin is used in 100 g of the Spirulina algae A method for obtaining a high-concentration zeaxanthin-containing poultry egg according to the above, wherein the poultry is a chicken or a poultry egg according to the above, or a method for obtaining a poultry egg according to the above. .

[0011]

DETAILED DESCRIPTION OF THE INVENTION Poultry as referred to in the present invention is chicken, quail,
It is a general term for turkey, guinea fowl, pigeon, duck, goose, etc. Chicken and quail eggs are generally used as poultry eggs. Spirulina (Spirulina) is a fine spiral algae of the genus Spirulina of the cyanobacterium Nostocidae, and includes, for example, Spirulina platensis, Spirulina maxima, Spirulina geitleri, and Spirulina sp.

Spirulina, which can be cultured artificially and is readily available and preferred, is Spirulina platensis, Spirulina maxima, Spirulina gaytreli, Spirulina siamise, and the like. These spirulina algae bodies
Zeaxanthin is added in an amount of 50 to 15 mg per 100 g of algal cells.
Contains 0mg.

[0013] Spirulina used in the present invention preferably contains zeaxanthin in an amount of 50 mg or more, more preferably 100 mg or more, per 100 g of algal cells. Spirulina alga bodies to be incorporated into poultry feeds may be wet alga bodies or dry alga bodies such as freeze-dried alga bodies and spray-dried alga bodies, but spray-dried alga bodies are preferred from the viewpoint of feed stability and cost. In the present invention, as a zeaxanthin source, spirulina alga bodies are, for example, 0.5% by weight or more, generally 0.5 to 10% by weight in the basic feed for adult breeding shown in Table 1, and in view of the egg production cost, Preferably 0.5-3
% By weight.

[0014]

[Table 1]

[0015]

EXAMPLES Next, the present invention will be described in detail with reference to Examples, where "%" in the text is on a weight basis. (Example 1) Basic feed administration group 1 using 40 laying hens
0 birds were set as a control group, and 10 birds were set in the test group. Additives to the basic feed were added as shown in Table 2 and reared for 2 weeks.

[0016]

[Table 2]

[0017] Five eggs were collected at random from the control plot and each test plot, and the yolks were collected and mixed, and then the amount of zeaxanthin in the yolk and the whole egg was measured by liquid chromatography. The results are shown in Table 3. The relative ratio in the table is a value when the amount of zeaxanthin in the control group is 1. The numerical values in Table 3 represent the amount of zeaxanthin (μg / 100
g) and relative ratios.

[0018]

[Table 3]

From these results, it was found that the amount of zeaxanthin in the test plots 2 and 3 was more than three times that in the control plots in both the yolk and the whole egg, and therefore, the spirulina dry alga body was 0.5% in the basic feed. With only the above addition, production of eggs containing high-concentration zeaxanthin became possible. In addition, the zeaxanthin transfer rate was calculated from the zeaxanthin intake of each group and the amount of zeaxanthin in the yolk in this test, and the results are shown in Table 4.

[0020]

[Table 4]

The above transfer rate was determined by the following equation. Transfer rate (%) = [(amount of zeaxanthin in yolk) / (intake of zeaxanthin)] × 100, and an increase in zeaxanthin = (amount of zeaxanthin in yolk of each test section) − (amount of zeaxanthin in yolk of control section) And

Zeaxanthin intake is calculated as feed intake = 1.
20 g / day, amount of zeaxanthin in Spirulina alga body = 1.
0 mg / g, Spirulina alga body added amount in feed = 0.3 g,
It was determined based on 0.6 g and 0.9 g / 100 g. In addition, an improvement in the color tone of the yolk (increased redness) was also observed depending on the amount of Spirulina algae added.

Zeaxanthin, which has a significant nutritional and physiological meaning, for example, usually has a content of about 100 μg% (whole egg) in chicken eggs, but by using a feed containing 0.5% by weight or more of Spirulina alga bodies, 380-520 μg%
(Whole egg), and it became possible to produce high-concentration zeaxanthin-containing chicken eggs.

[0024]

Industrial Applicability The present invention provides zeaxanthin, which has significant nutritional and physiological meanings, as a high-concentration zeaxanthin-containing poultry egg, which is useful as a food material that can be easily collected by humans, and a method for obtaining the poultry egg. it can.
