BEST MODE FOR CARRYING OUT THE INVENTION This embodiment is an invention relating to the animal feed according to claim 1. The animal feed of the present embodiment contains a material derived from young barley leaves . Below, to young wheat
The derived material is referred to as a wheat-derived material. Also, γ
-Aminobutyric acid is called GABA
To do. The materials derived from young barley leaf include young barley leaf powder, young barley leaf fragment and dried powder thereof, young barley leaf juice and dried powder thereof, young barley leaf extract and dried powder thereof, and the like. In addition, as the material derived from young barley leaves according to the present invention, it is more preferable to use the young barley leaf powder, the barley young leaf fragment, and its dry powder. This is because these materials contain a large amount of dietary fiber.

The term "wheat" is a general term for barley, wheat, rye, oats and the like belonging to the family Gramineae. In the present invention, any barley can be used.
It is preferable to use at least one of the group consisting of wheat, rye, and oats. In addition, young barley leaves are leaves containing barley leaves or stems, from the beginning of splitting to the beginning of heading,
It is harvested at a height of about 20 to 40 cm.

In this embodiment, as an example of young barley leaves,
Use young barley leaves. Since the green color of these young barley leaves will fade over time after harvest, the post-treatment will be carried out as quickly as possible.

After harvesting, young barley leaves are washed with water or the like and drained to leave them as they are, or to a suitable length (for example, 10c).
Cut to m) and proceed to the next GABA enrichment process. In addition, the young barley leaf may be cut into pieces after this cutting treatment. The fragmentation is carried out by a method commonly used by those skilled in the art, such as slicing or shredding to fragment the plant body. In particular,
Mix with a mixer, juicer and blender
Slurry is made by making a thick porridge (a suspension of liquid and solid).

Then, regarding the young barley leaves, the following procedure was used to increase the GABA originally contained in the young barley leaves.
ABA enrichment process. In the present embodiment, GAB
Although the A-enrichment treatment is performed after the washing, the present invention is not limited to this, and the GABA-enrichment treatment may be performed before the washing. The shredded wheat leaves are subjected to GABA enrichment by anaerobic heat retention. The anaerobic heat retention process is a process in which the anaerobic process and the heat retention process are simultaneously performed.

The anaerobic treatment means placing young barley leaves for a predetermined time under anaerobic conditions, that is, in the absence of oxygen or in an atmosphere of extremely low oxygen concentration. In the anaerobic heat retention treatment, first, young wheat leaves are placed in an anaerobic treatment device having a sealing property and a temperature adjusting function. The air in this device is replaced with carbon dioxide gas to obtain an anaerobic condition. At the same time, the temperature inside the anaerobic treatment device is adjusted to a temperature of about 20 to 50 ° C. to keep it warm. afterwards,
While keeping anaerobic and temperature conditions almost constant, 10
The anaerobic heat retention treatment is performed by leaving it for a period of from minutes to 24 hours.

In this embodiment, carbon dioxide gas is used as the replacement gas for the anaerobic treatment, but other gas such as nitrogen gas may be used. Further, the inside of the anaerobic treatment apparatus may be depressurized and maintained in a high vacuum state without replacing the air with the replacement gas.

The temperature of the anaerobic heat insulation treatment is about 20-50.
℃ means that the temperature of heat insulation is less than 20 ℃, 50
This is because the GABA content does not increase sufficiently at temperatures higher than ° C. The temperature of the anaerobic heat insulation treatment is about 30.
When the temperature is set to ˜45 ° C., and further to about 38 ° C. to 42 ° C., a large amount of GABA can be obtained, which is preferable. The time for the anaerobic heat retention treatment is 10 minutes to 24 hours, but if it is 1 to 6 hours,
It is more preferable from the viewpoint of flavor retention.

In the present embodiment, the anaerobic heat retention treatment step is performed as the GABA enrichment treatment step, but the present invention is not limited to this, and the anaerobic treatment, heat retention treatment and immersion treatment may be performed alone or in combination. . The anaerobic treatment is performed under the same procedure and conditions as the anaerobic heat retention treatment except that the temperature is not adjusted.

The heat retaining treatment is a warm water soaking treatment in which young leaves are soaked in warm water maintained at a predetermined temperature, a hot water shower treatment in which a warm water shower set at a predetermined temperature is applied to the young leaves, and an infrared irradiation treatment for irradiating the young leaves with infrared rays. , Incubator treatment, etc., in which young leaves are left in a constant temperature bath set to a predetermined temperature.

The heat retention treatment is performed at about 20 to 50 ° C. The temperature of the heat insulating treatment is set to about 20 to 50 ° C. because the GABA content does not increase sufficiently when the temperature of the heat insulating treatment is lower than 20 ° C. or higher than 50 ° C. In addition, the temperature of the heat insulation treatment is about 30 to 45 ° C., and further about 3
When the temperature is 8 ° C to 42 ° C, a large amount of GABA can be obtained, which is preferable. The heat retention time is 10 minutes to 24 hours.
Further, it is preferable to set the time to 1 to 6 hours from the viewpoint of flavor retention.

The dipping treatment as the GABA enrichment treatment is carried out by dipping the shredded barley leaves in a predetermined dipping solution. Here, the predetermined dipping solution means an aqueous solution containing a food material containing at least one of an aqueous solution of glutamic acid, an aqueous solution of glutamate, an aqueous solution of glutamic acid and glutamate, and glutamic acid and glutamate. The aqueous solution may be either a saturated aqueous solution or a supersaturated aqueous solution. As the dipping solution, a suspension containing a substance such as glutamic acid may be used instead of the aqueous solution. Immersion treatment is from glutamic acid to GAB
It is carried out at a temperature within the range where the enzyme that catalyzes the conversion to A is not inactivated. Specifically, it may be carried out at a temperature of 20 to 50 ° C.
In addition, the immersion treatment has a pH of 3.5 to 9.0, preferably p.
Perform at H4.0-7.0.

The above-mentioned anaerobic treatment, heat retention treatment, immersion treatment, etc.
The ABA enrichment treatment increases the content of GABA contained in the debris of young wheat leaves, which is usually more than double the amount of GABA originally contained in the young leaves. By properly selecting the conditions, GABA originally contained in young leaves
It is also possible to increase the amount by 3 times or more, or 5 times or more. In addition, usually 200-300m for young barley leaves
It contains g / 100 g of GABA.

After that, as a deteriorating treatment for the young barley leaves, a microwave treatment is carried out instead of the conventional blanching treatment by hot water treatment / steaming treatment. This microwave treatment prevents deterioration of young barley leaves such as deterioration and flavor change, makes it possible to retain the green color of the young barley leaves, and makes GABA in the young barley leaves less likely to be lost. is there. It can be said that the GABA holding process is also performed at the same time in that GABA is less likely to be lost.

The microwave treatment prevents decomposition and elution of vitamins and minerals in young wheat leaves. Furthermore, by performing a microwave treatment as a deterioration preventing treatment for young wheat leaves, it is possible to solve the problems in the case of performing a blanching treatment which has been generally performed conventionally.

That is, as a treatment for preventing deterioration of young barley leaves,
Conventionally, branching processing has been performed. Here, the blanching treatment generally refers to hot water treatment, steam heat treatment or the like performed to prevent deterioration of food such as discoloration due to fading. However, conventional blanching treatment, for example, when performing blanching treatment by dipping the barley leaf described in Japanese Patent No. 2544302 in hot water containing salt and sodium bicarbonate, GABA in the barley leaf is lost. There was a problem of being broken. On the other hand, the microwave treatment of the present embodiment can solve the problem of the conventional method that GABA in young wheat leaves is retained and GABA is lost.

The microwave treatment is carried out by appropriately adjusting the wavelength of the microwave, the output of the microwave irradiator, and the irradiation time so that the enzyme present in the young barley leaves, which is involved in the alteration such as the fading of green and the change of flavor, etc. May be deactivated or the green color may not be lost due to an increase in product temperature due to irradiation.

Specifically, when a microwave irradiation device of 2450 MHz and 500 W is used, young wheat leaves are
Irradiation may be performed for 0.5 to 10 minutes per 100 g of wet weight. If the irradiation time is less than 0.5 minutes, the inactivation of the enzyme will be insufficient and the young barley leaves will be easily discolored after the treatment. Further, when the irradiation time exceeds 10 minutes, young barley leaves are discolored and GABA tends to decrease. The irradiation treatment is more preferably 0.5 to 5 minutes, more preferably 0.5 to 1 minute. Even when treated for 5 minutes, GABA remains about 80% of the amount contained before irradiation, and the enzyme involved in alteration is also inactivated.

Then, the young barley leaves obtained by the above procedure are dried. Drying is performed by a known method such as hot air drying, high pressure steam drying, electromagnetic wave drying, freeze drying, and spray drying.
Drying is preferably performed at a temperature as low as possible. Under high temperature,
This is because GABA in the fragment of young wheat leaves is easily lost. Even when heating and drying, for example, 50 to 80
C., preferably 55 to 65.degree. C. When the material derived from young wheat leaves is liquid, it may be spray-dried or freeze-dried after adding excipients such as dextrin, cyclodextrin, starch and maltose. The drying is performed so that the water content of the young barley leaves is 10% or less, preferably 5% or less. After that, crushing or crushing is performed. Grinding is according to known methods, for example crusher,

Next, the young leaves were packed in a plastic bag, the air in the bag was evacuated, then filled with nitrogen, and subjected to GABA enrichment treatment by anaerobic treatment at 40 ° C. for 6 hours. This was dried with warm air at 60 ° C. for 10 hours so that the water content was 5% or less, and coarsely crushed to obtain a raw material 3 derived from young wheat leaves. The material 3 derived from young barley leaves was mixed with the basic feed so as to be 10% by weight to obtain a young wheat barley feed 3 of the present invention.
On the other hand, the young leaf of barley was processed into the material 4 derived from the young leaf of wheat by the same procedure except that the GABA enrichment treatment was not performed. This material 4 derived from young barley leaves was mixed with the basic feed so as to be 10% by weight to obtain a young wheat barley feed 4 of the present invention.
In addition, basic feed that does not contain materials derived from young wheat leaves,
It was prepared as a conventional basic feed.

And, the above-mentioned barley leaf feeds 3, 4 of the present invention
The conventional basic feed was given to an 8-week-old SD rat group consisting of 6 animals for 10 days for preliminary breeding. Then, for 4 hours, the wire mesh was restrained in a cage of 4.5 cm × 4.5 cm × 16.0 cm to apply stress. Then, the anti-stress effect was evaluated by the change in emotional behavior (activity distance (cm), number of standings) before and after stress loading. The results are shown in Table 2.

[0053]

[Table 2]

From the results shown in Table 2, in comparison with the group fed with the conventional basic feed, the groups fed with the inventive wheat barley leaves 3 and 4 showed less decrease in the action distance and the number of standings after stress loading. , The reduction of emotional behavior was suppressed. Therefore, it was found that the animal feed of the present invention has an anti-stress effect on an animal when it is given to a rat, which is an example of the animal, because the reduction of emotional behavior due to stress load is suppressed.

(Embodiment 3) This embodiment is an embodiment of the invention according to claims 1 to 3. The animal feed of this example is an animal feed containing a coarsely crushed young barley leaf material as a material derived from young barley leaf. In this example, a young barley leaf, which is an example of a young barley leaf, was processed by the same procedure as the material 2 derived from the young barley leaf of Example 1 to obtain a material 5 derived from the young barley leaf. This material 5 derived from young barley leaf was mixed with 10% of a basic feed for a general broiler to obtain a barley leaf feed 5 of the present invention. In addition, a basic feed for broilers containing no wheat-derived material was prepared as a conventional basic feed.
