Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food and drink for athletes containing ferritin, vitamin C, a protein material and an indigestible polysaccharide. More specifically, by ingesting ferritin together with vitamin C, a protein material, and an indigestible polysaccharide, which have an effect of assisting absorption of iron, an athlete having the effect of further increasing iron stores and increasing endurance. For food and drink.

2. Description of the Related Art A typical sports food and drink for athletes is a sports drink, which is used to supplement water, energy, vitamins and minerals lost during exercise. It is a type to which minerals and minerals are added, and the osmotic pressure is almost the same as that of body fluid, and it is claimed that it is quickly absorbed without any burden on the body. Also,
There are also foods and drinks for athletes fortified with minerals and vitamins such as calcium and iron, which are intended to supplement the minerals and vitamins that are lost during exercise. On the other hand, there are foods and drinks for athletes that are fortified with protein for the purpose of strengthening muscles, but those that are designed to fortify and ingest specific components more actively than those lost during exercise, but other specific components. There was no food or drink for athletes who fortified it and made it more active than it would be lost during exercise.

On the other hand, it has been reported that, in an exercise requiring endurance such as a marathon or a relay race, an athlete who has a large amount of stored iron is more advantageous at the final stage of the exercise. The simplest way to increase this stored iron is to get more iron. Regarding iron supplementation, recently, many foods and drinks containing an iron material for nutritional supplementation are provided on the market. The market is expanding year by year, and some athletes use such food and drink.
As for the iron material contained in such foods and drinks, inorganic iron (non-heme iron) such as ferrous sulfate, iron citrate and iron pyrophosphate, which are easily available, are often used. , Inorganic iron is not only poorly absorbed in the human body, but when ingested, it is liable to cause gastrointestinal disorders, causing anorexia and constipation.

Ferritin is an iron-binding protein which exists in almost all organs, mainly organs such as spleen, liver and bone marrow of animals, and which has a role of storing excess iron, and like other inorganic irons and the like. It is used as a food and drink and a drug effective in the prevention and treatment of iron deficiency anemia. Unlike inorganic iron, this ferritin has the advantages that it has a high iron absorption efficiency in the human body and does not cause gastrointestinal disorders when ingested.

[0005] As an athlete's food and drink for exercise requiring endurance, a caffeine-added exercise drink (Japanese Patent Laid-Open No. Hei 3
-143377) and carnitine-containing beverages (JP-A-3-2)
59070) and the like are known, but the former has a problem that it is a temporary one and becomes positive in a doping test, and the latter has a purpose of helping to burn body fat and shaping. It does not increase endurance.

[0006] Fructose, glucose and dextrin are generally used as a source of energy supply for sports drinks. Furthermore, vitamin C, protein materials, indigestible polysaccharides, vitamin B _12, and folic acid are known to have an effect of assisting absorption of iron.

[0007]

With conventional foods and drinks for athletes, little effect of enhancing endurance can be expected, and the purpose is to replenish water, energy, vitamins and minerals lost during exercise and to strengthen muscle strength. It was something that It is an object of the present invention to provide an athlete's food and drink that has the effect of further increasing iron storage and increasing endurance by ingesting ferritin together with a material having an effect of assisting absorption of iron.

[0008]

Means for Solving the Problems As a result of diligent research, the inventors of the present invention further increased iron storage by adding ferritin to an athlete's food and drink together with a material having an effect of assisting absorption of iron. It was found that food and drink for athletes having the effect of increasing endurance can be made. That is, the present invention actively and efficiently ingests ferritin by adding vitamin C, a protein material, and an indigestible polysaccharide, which are effective in assisting iron absorption, to ferritin. The present invention relates to an athlete's food and drink which has the effect of further increasing stored iron and increasing endurance.

The ferritin used in the present invention is not particularly limited, and those extracted and purified from organs such as spleen, liver and bone marrow of animals can be used, but extracted and purified from bovine spleen, It is preferable that the iron content is 10 to 20% or that the iron content is adjusted by diluting it with dextrin or the like.

The amount of ferritin added as iron is 10 to 30 mg, preferably 10 to 25 m, per daily intake.
g, more preferably 12 to 20 mg. Below this range, the added amount of iron is small, and the effect of increasing the stored iron cannot be expected. Exceeding this range is also meaningless because the amount of excretion also increases, and the effect of increasing iron storage remains unchanged. It should be noted that in the present application, "a daily intake"
Refers to the total recommended amount of food to be eaten per day, regardless of the number of times of eating per day.

The vitamin C used in the present invention may be either ascorbic acid or sodium ascorbate, or both may be used at the same time. The amount of vitamin C to be added is not particularly limited as long as it is within a range that is considered by common sense, but the total amount of ascorbic acid and sodium ascorbate is, for example, 10 to 2000 mg per serving,
Preferably 100-1000 mg, more preferably 20
It is 0 to 800 mg. However, since vitamin C is sensitive to heat, when processed into foods and drinks, product forms that require heat of 50 to 60 ° C. or more from the time when the product is added to vitamin C, such as liquid drinks and jelly drinks (drink jelly). In the case of), etc., considering the loss due to heating, the amount is 1.2 times or more of the amount actually added (the above amount), preferably 1.5 to
It is recommended to add 2.5 times the amount. Also, under conditions involving a high temperature of 150 ° C. or higher, almost 100% of vitamin C is inactivated, so it is desirable to avoid such conditions. If the amount of vitamin C added is less than this range, it is meaningless as an iron absorption aid, and if it is too large, it becomes an excessive intake of vitamins.

The protein material used in the present invention is preferably gelatin, milk protein, or a milk protein decomposition product, which is known to have an effect of assisting absorption of iron. The gelatin here is obtained by extracting from animal bones, cartilage, skin, tendons, ligaments, etc., and is generally called water-soluble gelatin. These are further acid-decomposed, alkali-decomposed, enzyme-decomposed, etc. It may be decomposed by a method and made soluble in cold water. Milk proteins are casein, sodium caseinate, calcium caseinate, whey protein, total milk protein, skim milk powder, whole milk powder, etc., and milk protein hydrolyzate is a product obtained by decomposing milk protein with an enzyme or purifying after decomposition. It is a thing. As milk protein hydrolyzate, casein calcium peptide (calcium casein peptide) obtained by degrading casein calcium with a protease derived from Aspergillus is known, and in the purified product after degradation, casein was decomposed with trypsin. Thereafter, casein phosphopeptides and the like obtained by adding ferric chloride, calcium chloride and the like and ethanol to separate and purify as a precipitate are known.

The amount of the protein material added is not particularly limited as long as it is within the range of common sense, but is, for example, 100 to 5000 mg, preferably 20 per serving.
0 to 2000 mg, more preferably 300 to 1000 m
It is g. Further, in the case of a product obtained by decomposing milk protein with an enzyme or the like, for example, casein phosphopeptide and the like, since the effect of assisting iron absorption is high, the amount may be smaller than the above amount, for example, per serving. 0.1-100m
g, preferably 1 to 50 mg, more preferably 5 to 30
mg. If it is less than this range, it is meaningless as an iron absorption aid, and if it is more than this range, the taste becomes poor, and
In the case of beverages, the solubility is poor, and in the case of foods such as tablets and capsules, it is difficult to eat because the amount consumed is large, which is not preferable.

The indigestible polysaccharide used in the present invention may be any that generally falls within the category of water-soluble dietary fiber, and examples thereof include thickening polysaccharides, thickening polysaccharide degradation products, and indigestible starch. . Thickening polysaccharides include guar gum, locust bean gum, tamarind gum, carrageenan, xanthan gum, gum arabic, karaya gum, pectin, agar, alginic acid, sodium alginate, propylene glycol alginate, but poor solubility in water. ,
Since it is not suitable as a food / beverage material of the present invention because it has a high viscosity when dissolved and sticks in the mouth when eating, it is not preferable, and it is preferable to use these decomposed products.

The decomposed product of the thickened polysaccharide may be any decomposed product of the above-mentioned thickened polysaccharide, and as the decomposition method, known methods such as enzymatic decomposition, acid decomposition, alkali decomposition and the like can be used, preferably In the case of a guar gum degradation product, for example, the following method can be mentioned. Add citric acid to 1000 parts of water to adjust pH to 3
After adjusting to ~ 4, galactomannanase 0.1
˜0.5 parts and 50 to 200 parts of guar gum powder are added and mixed, and decomposed by reacting with an enzyme at 40 to 45 ° C. for 15 to 40 hours and neutralized with sodium hydroxide, then 90 to 100 ° C.
A method of inactivating the enzyme by heating for 10 to 20 minutes, removing insoluble matter by filtration, and then spray-drying to obtain a guar gum decomposition product.

The indigestible starch is obtained by subjecting starch to thermal decomposition after heating and purification treatment, and is also referred to as purified culture-baked dextrin. Commercially available products of these materials include guar gum decomposition products such as Sunfiber [Taiyo Kagaku Co., Ltd.], Guafiber [Meiji Seika Co., Ltd.], Fiberron [Dainippon Pharmaceutical Co., Ltd.]. Examples of the resistant starch include pine fiber [Matsuya Chemical Co., Ltd.] and the like.

The amount of the indigestible polysaccharide to be added is not particularly limited as long as it is within the range considered by common sense, but it is, for example, 100 to 5000 mg, preferably 300 to 3000 mg, and further preferably, per serving amount. Maki is 500-2
It is 000 mg. If it is less than this range, it is meaningless as an iron absorption aid, and if it is more than this range, the amount consumed will increase, and in the case of beverages, the viscosity will increase and it will be difficult to eat, which is not preferable.

Ferritin, vitamin C used in the present invention,
As raw materials other than protein materials and indigestible polysaccharides, raw materials that can be used in ordinary athlete food and drink, for example, sweeteners (sugar, fructose, glucose, fructose-glucose liquid sugar, aspartame, stevia, etc.), sourness Materials (citric acid, malic acid, etc.), excipients (dextrin, starch, etc.),
Flavors, fruit juices, colorings, vitamins (vitamin A, vitamin B ₁ , vitamin B ₂ , vitamin B ₆ , vitamin B ₁₂ ,
Nicotinic acid, niacin (nicotinic acid amide), vitamin D group, vitamin E, vitamin K, biotin (vitamin H), pantothenic acid, folic acid, etc.), minerals (sodium, potassium, calcium, magnesium, zinc, copper,
Salts containing phosphorus, manganese, iodine and the like can be used.

Further, vitamin B12 and folic acid, which are also known to have an effect of assisting absorption of iron, may be added at the same time. The amount of vitamin B ₁₂ to be added at this time is not particularly limited as long as it is within a range that is considered by common sense, but it is, for example, 1 to 20 μg, and preferably 2 per serving.
˜15 μg, more preferably 3 to 10 μg. If it is less than this range, it is meaningless as an iron absorption aid, and if it is too large, it becomes an excessive intake of vitamins, and if it is too much, the iron absorption assisting effect does not change, so it is meaningless.

The amount of folic acid added is not particularly limited as long as it is within the range that can be considered by common sense, but it is, for example, 0.1 to 2 mg per serving, and preferably 0.1.
2 to 1.5 mg, more preferably 0.3 to 1 mg. If it is less than this range, it is meaningless as an iron absorption aid, and if it is more than this, it becomes an excessive intake of vitamins.
There is no point in adding too much iron because it does not change the iron absorption assisting effect.

In the case of beverages, the dextrin contained for energy supply may be either linear or branched, and its DE range is 5 to 30. Good, preferably 5 to 20, and more preferably 8 to 15. When the DE is less than this range, the viscosity is high and the solubility is deteriorated, which is not preferable. When it exceeds this range, the osmotic pressure becomes high, which is not preferable. The amount of dextrin added is not particularly limited as long as it is within a range that can be considered by common sense, but for example, 1 to 20 g, preferably 2 to 15 g, per one serving.
More preferably, it is 3 to 10 g. If it is less than this range, it is meaningless as energy supply, and if it is more than this range, the solubility is poor and the viscosity becomes high, which is not preferable.

As the form, powdered drinks, liquid drinks and jelly drinks (drinking jelly) which are easy, portable and excellent in storability
The form of tablets, tablets and capsules is preferred. If the processing temperature of baked confectionery such as cookies is 150 ° C or higher,
It is considered that the effect is reduced by deactivating vitamins.

The number of times of drinking per day for ingesting an effective amount of iron is preferably 3 times or less, more preferably 2 times or less. Particularly preferably, it is once. If it is more than that, it is not preferable in terms of simplicity.

In the case of powdered beverages, the amount to be used for one drinking is not particularly limited as long as it is within a range that can be considered by common sense, but for example, it may be in the range of 1.5 to 35 g, preferably 2 to 35 g. It is 25 g, more preferably 3 to 15 g, particularly preferably 5 to 10 g. When the amount is less than this range, it is not possible to contain all the necessary components, and when the amount is more than the above range, the solubility is deteriorated, which is not preferable.

There is no particular limitation on the amount of water that dissolves a single drink as long as it is within the range of common sense.
For example, 10 to 250 ml, preferably 30 to 2
It is 00 ml, more preferably 50 to 150 ml.
If the amount is less than this range, it becomes difficult to dissolve the powdered beverage, and if the amount is more than this range, it becomes difficult to drink, which is not preferable. In addition, liquid dose, jelly drink (drink jelly) is not particularly limited, as long as it is a range that can be considered in common sense, in the case of a product provided in a state where components are dissolved in water, for example, 10 to 250 ml, preferably 30
~ 200 ml, more preferably 50-150 ml. If it is less than this range, the components are difficult to dissolve during production, and the viscosity of the product is high, and if it is too large, it becomes difficult to drink, which is not preferable.

When the form is tablets or capsules, the number of tablets or capsules eaten per day for ingesting an effective amount of iron is not particularly limited as long as it is within a range that can be considered by common sense, but for example, 3 The number is preferably about 30 to 30 grains, preferably 5 to 20 grains, more preferably 8 to 15 grains. If the amount is less than this range, all the necessary components cannot be contained, and if one tries to contain all the necessary components, one grain becomes large and it becomes difficult to eat.
It is not preferable because the amount (number) of foods to be eaten at one time increases and the number of times of food intake per day increases, which makes it difficult to eat.
