DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an antiallergic food. More specifically, the present invention relates to an antiallergic food which prevents or alleviates allergy and has no side effects such as rebound.

[0002]

2. Description of the Related Art An allergy is a symptom caused by overproduction of various physiologically active substances (hereinafter referred to as chemical mediators) including histamine due to an overreaction of an antigen-antibody reaction. At present, the most serious problem is type I allergy called immediate allergy. In vivo reactions leading to the onset of type I allergy are roughly classified into three types. The first is a reaction in which the chemical mediator is overproduced from arachidonic acid by cyclooxygenase and mainly acts on the circulatory system, causing symptoms such as rhinitis, sneezing, tears, and sore throat (hereinafter, cyclooxygenase pathway). Chemical mediators are overproduced by lipoxygenase from acid, and the reaction mainly causes exacerbation of mucosal inflammation and skin inflammation (hereinafter, lipoxygenase pathway).
This is a reaction (hereinafter referred to as macrophage pathway) in which TNF is overproduced from macrophages and the like, which causes exacerbation of skin inflammation. The synergism of these three reaction pathways causes allergic symptoms such as rhinitis, sneezing, watery eyes, and dermatitis. At present, allergies are also called modern diseases,
Allergy sufferers are on the rise and it is said that 30% of the population has some allergic symptoms and 10% have atopic dermatitis symptoms.

Under such circumstances, antihistamines, antiallergic agents, steroids and the like have been developed and used as drugs. These drugs have side effects such as exacerbation of symptoms (rebound phenomenon) due to long-term administration, drowsiness by acting on the central nervous system, and effects on the endocrine system through percutaneous absorption. It is necessary to use under the control of.

[0004] On the other hand, as a safe and anti-allergic material having no side effects, those having anti-allergic activity among conventional foods have been sought, and development as a food material has been attempted (JP-A-61-291524). , Japanese Patent Laid-Open No. 1-1212
17, JP-A-7-215884). Already on the market and widely recognized is the tea (Rubussua
vissimus) and bean leaf extract extracted from leaves of perilla (Perilla frutescens) with hot water. Clinical studies and animal experiments have confirmed that bean tea extract suppresses the first reaction by controlling the activity of cyclooxygenase, and in particular reduces or prevents the development of cardiovascular allergies such as rhinitis, sneezing, and sore throat. (Otolaryngology perspective; Vol.38, No.4, 519
5321995, inflammation; Vol. 15, No. 2, 167-173 1995).
Perilla leaf extract has been confirmed to alleviate and prevent allergic symptoms such as skin inflammation by suppressing the third reaction, namely, TNF production from macrophages and the like (Fragrance journal; Vol. 23, No. 5). , 43-48 1
995, Vol.23, No.7, 90-94 1995).

[0005] These materials are used as functional components of anti-allergic foods because they are safe and have no side effects even after long-term regular ingestion because they are made from ordinary foods with a long eating experience as raw materials.

[0006]

However, as described above, many side effects of drugs are apparent, and it is necessary to use them under the control of a physician. In addition, bean tea extract and perilla leaf extract, which are usually made from food, have no side effects and are excellent as an anti-allergic material, but only suppress a part of the biological reaction leading to the onset of allergy as described above. is there. Therefore, as a result, although alleviating and preventing some of the allergic symptoms are effective, it is not expected to alleviate or prevent the overall symptoms. It has been pointed out that when an allergy develops, it is highly likely that various symptoms of a living body occur simultaneously or sequentially with each aging, and this phenomenon is called an allergy march. Therefore, in order to efficiently suppress allergic symptoms, it is important to suppress the overall reaction leading to the onset of allergy. In addition, in recent years, in the case of atopic dermatitis, which has been increasing and becoming a problem in a wide age group from infants to adults, the second reaction pathway lacking in the tea bean extract and perilla leaf extract, namely, from arachidonic acid It is important to suppress the reaction leading to overproduction of chemical mediators by lipoxygenase. In this reaction pathway,
Leukotriene B4 (L
TB4), 5-hydroxyeicosatetraenoic acid (5-
This is because a chemical mediator such as HETE) is specifically produced. Thus, it is important to provide an antiallergic food having a function of alleviating and preventing the symptoms of allergy, and an object of the present invention.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is as follows.
It is achieved by an antiallergic food containing a water-soluble extract, a tea extract and a perilla leaf extract extracted from the seeds of a Labiatae plant. . The present invention has found that a water-soluble extract of perilla seeds has an anti-allergic effect, and by using together with a known anti-allergic material, bean tea extract and perilla leaf extract, an unprecedented overall This was done by recognizing the alleviation and prevention of allergic symptoms.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The water-soluble extract extracted from the seeds of a Labiatae plant in the present invention can be obtained by pulverizing perilla seeds, extracting with a hydrophilic solvent such as ethanol, and concentrating. Perilla seed is a perilla plant, Perilla frutescens Britton var.japon
ica) and perilla (Perilla frutescens Britton var cr)
ispa), but closely related seeds such as Aochirimendiso, Yamadiso and Himejiso can also be used. The method of obtaining a water-soluble extract is, for example, pulverization by pulverizing seeds, extracting with ethanol at about 40 to 60 ° C for 3 to 6 hours, filtering, concentrating the filtrate, and spray-drying as necessary. Extract can be obtained.
In the present invention, a concentrated liquid or a powdered liquid can be used.

In order to process the extract obtained as described above into an antiallergic food, it is necessary to make it possible to ingest an appropriate amount as a dried seed extract. It can be in a form and may be performed according to conventional food processing. That is, when processing into foods such as beverages, confectionery, staple foods, powders, tablets, etc., it is sufficient to mix the raw material with the seed extract and process by the conventional method,
If necessary, additives such as a flavor, a sweetener, a colorant, and an excipient may be added. The appropriate amount of the dried seed extract is generally in the range of 10 mg to 30 mg per day, and the amount of the seed extract may be appropriately determined in consideration of the intake amount and the number of inoculations.

In addition, a known antiallergic material, a tea bean extract and a perilla leaf extract, are added simultaneously. This alleviates allergic symptoms overall. For example, after drying the leaves of bean tea, the bean extract may be dried with hot water of about 60 ° C.
It is manufactured by extracting for about 3 hours, filtering, concentrating under reduced pressure and boiling. Perilla leaf extract is produced, for example, by drying perilla leaves, extracting with hot water at about 60 ° C. for 2 to 3 hours, cooling and aging, concentrating under reduced pressure, and adding alcohol. It is said that these compounding amounts are determined as the respective extract effective required amounts, and that, in terms of dry matter, 90-240 m
g, perilla leaf extract intake to be 6 to 18 mg,
It is only necessary to mix them appropriately in consideration of the number of inoculations. As described above, the present invention is characterized in that a novel water-soluble extract of perilla seed is used in combination with a known bean extract and perilla leaf extract.

The thus obtained food containing the seed extract can alleviate allergic symptoms, which were only partially alleviated by the use of the bean tea extract and the perilla leaf extract alone. The observation suggests that the lipoxygenase pathway is also effectively suppressed. The mechanism of this function expression is unknown, but since the seed extract of the present invention is a water-soluble extract, it is clear that perilla oil, a known anti-allergic component contained in perilla seeds, is not involved. It is. It has been pointed out that the seed component has a strong antioxidant power because it is not glycosylated like the leaf components such as bean tea extract and perilla leaf extract, and this strong antioxidant power is associated with allergic reactions such as lipoxygenase pathway. When suppressing the biological reaction leading to the onset, and when used in combination with bean tea extract and perilla leaf extract,
It is possible that they have a synergistic antiallergic function. In any case, perilla seed extract according to the present invention,
Foods using a combination of bean tea extract and perilla leaf extract have the effect of alleviating and preventing the overall symptoms of allergy, which have not been recognized so far.
