DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid food having a high zinc and copper content. For more information, oysters
The present invention relates to a liquid food which contains an extract and soybean protein, has a high content of zinc and copper, and has a reduced odor derived from an oyster extract.

[0002]

2. Description of the Related Art Various enteral nutritional supplements have been used for pre- and post-operative nutritional supplementation of patients and for nutritional supplementation of bedridden elderly people who cannot ingest normal foods orally.

[0003] Commercially available enteral nutrients can be broadly classified into those belonging to drugs (listed with drug prices) and those belonging to foods (listed without drug prices). Of these, enteral nutritional products belonging to food
Except for infant formula, addition of mineral components such as zinc and copper useful for regulating physiological functions has not been recognized.

Therefore, oysters, which themselves contain a large amount of mineral components such as glycogen, taurine, zinc, etc., have attracted attention as one of the raw materials of enteral nutritional supplements as food materials with high nutritional value. It is used for nutritional supplements such as enteral nutritional supplements.

[0005]

The daily intake of minerals generally considered desirable for adults is 8 to 15 mg for zinc and 1 to 2 mg for copper.
It is. However, as described above, since no mineral component is added to the enteral nutrition, the content of zinc and copper in the conventional enteral nutrition is low, and zinc on average is 2 to 4 mg / day. 2000kcal, copper 0.2 ~
Contains only 0.4 mg / 2000 kcal.

[0006] In general, even persimmon extract, which is said to have high nutritional value and contains many mineral components, contains 60 ppm or more of zinc. Ingestion of 6 g can lead to a zinc intake of 0.36 mg or more per day, but still only provides about 10 to 20% of the desired daily zinc intake. The content of copper is even lower than that of zinc, and it is impossible to secure a desirable daily intake.

[0007] Furthermore, the oyster meat extract has a problem in flavor because it has a characteristic odor of oysters, and it is difficult to increase the intake due to the odor.

[0008] The present invention is to solve the above-mentioned problems of the prior art, and can ingest a large amount of zinc, copper, and other mineral components which are useful for regulating human physiological functions, and have a flavor. An object of the present invention is to obtain a liquid food which is excellent in nutritional supplements such as food enteral nutritional supplements and nutritional drinks for general consumers.

[0009]

Means for Solving the Problems The present inventors have made it possible to increase the content of zinc, copper and other mineral components in a liquid food by including both oyster extract and soybean protein in the liquid food. The inventors have found that soybean proteins have an action of masking the characteristic odor of persimmon, and have completed the present invention.

[0010] That is, the present invention provides a liquid food containing oyster extract and soybean protein.

Hereinafter, the present invention will be described in detail.

[0012] Oysters are bivalves belonging to molluscs and bryophytes, and include oysters, oysters, and mussels, all of which are edible. As the oyster extract used in the present invention, the peel of fresh or peeled oysters of these oysters, as they are or after enzymatic decomposition, are extracted with hot water or an organic solvent, or organic solvents after hot water extraction. Can be used. Also,
Pastes obtained by concentrating the liquid extract with hot water or an organic solvent, and further dried powders can be used.

[0013] The oyster extract thus obtained includes:
It contains zinc, copper, other minerals, glycogen as a stored carbohydrate, various nutrients such as taurine and vitamins, which are sulfur-containing amino acids and have an effect of improving lipid metabolism. Particularly, zinc is contained in a large amount, and its content ratio is calculated as solid content (that is, the amount contained in the solid content of the oyster extract).
And it is about 10 to 200 mg / solid content of about 100 g. Further, the content ratio of copper is about 1.5 to 30 mg / solid content of about 100 g in terms of solid content. In addition, a commercial item can be used as such an oyster extract.

In the liquid food of the present invention, the content ratio of the oyster extract is not particularly limited. However, if it is too much, a peculiar smell of oyster appears and the flavor is reduced, and if it is too small, it is impossible to take in sufficient zinc. Therefore, it is usually preferable that the content of the oyster extract is 0.1 to 2.0% by weight in terms of solid content.

On the other hand, in the present invention, as the soybean protein, those obtained from soybean by a conventional method can be used. For example, a purified water extract of defatted soybean after oil extraction and dried one may be used. Can be. Such a dried product usually contains about 50 to 95% of protein.

The present inventors have found that the soy protein has a significantly higher copper content than other protein materials such as egg protein and milk protein, and usually 100 g of egg protein (dried egg white).
The copper content in the soy protein (dry matter) is about 2.0 mg while the copper content in the milk protein (dry casein) is less than 0.1 mg while the copper content in the milk protein (dry casein) 100 g is less than 0.1 mg. Was found. Therefore, when this soybean protein is used together with the above-mentioned oyster extract as a component of a liquid food, it is possible to greatly increase the content of both zinc and copper in the liquid food.

Furthermore, the present inventors have found that soy protein has an action of masking the characteristic odor of oysters. Therefore, by using soybean protein together with the oyster extract as a component of the liquid food, the odor of the oyster extract can be suppressed, and the flavor of the liquid food can be improved.

In the liquid food of the present invention, the content ratio of soy protein is not particularly limited. However, if it is too large, a blue odor peculiar to soy protein appears and the flavor is impaired, or the protein is denatured when sterilized. This is not preferable because it may cause skewing and aggregation. Conversely, if the amount is too small, it is not preferable because sufficient copper cannot be taken. Therefore, usually, the content of soy protein in terms of solid content is adjusted to 0.3 to 5.0.
It is preferable to set the weight%.

Also, regarding the ratio of the oyster extract to the soybean protein, if the ratio of the soybean protein to the oyster extract is too small, the odor of the oyster extract cannot be sufficiently masked. It is preferable that the soybean protein is contained in an amount of 15 to 5,000 parts by weight per 100 parts by weight of the oyster extract in terms of minutes.

The liquid food of the present invention contains, in addition to the above-mentioned oyster extract and soybean protein, a balance of nutritional components, an increase in calorie intake, storage stability, and improvement of patient's stool (for diarrhea and constipation). And adjusting the number of defecations to an appropriate range), etc., if necessary.
For example, dietary fiber, oligosaccharides and the like can be contained in order to further enrich minerals, and wheat protein, milk protein, egg protein and the like can be contained as protein components. Various vitamins can be included. As a calorie source, vegetable or animal lipids can be added. Here, as vegetable lipids, for example, soybean oil, rice oil, safflower oil, cottonseed oil,
Corn oil and the like can be given, and as animal fats and oils,
Tallow, lard, sheep fat, fish fat, and the like can be given. Furthermore, sugars such as dextrin, sugar, and powdered candy can be used as a calorie source. In addition, yolk lecithin,
An emulsifier such as a sucrose fatty acid ester, a spice, a seasoning, a preservative, water and the like can be contained.

The liquid food of the present invention can be produced by mixing the above-mentioned components according to a conventional method. For example, as shown in FIG. 1, a mixer is charged with fresh water, saccharides such as dextrin, proteins such as soybean proteins, lipids such as edible vegetable oils, vitamins, minerals, emulsifiers, and the like, mixed and stirred, and further mixed with a homogenizer. By homogenizing, filling this into containers such as cans, retort pouches, bottles, etc., and sterilizing, a liquid food product can be obtained.

The liquid food of the present invention can be widely used as a food intended for nutritional supplementation, such as a food enteral nutritional supplement and a nutritional beverage for general consumers.

[0023]

Since the liquid food of the present invention contains both oyster extract and soybean protein, it contains abundant minerals derived therefrom, particularly zinc derived from oyster extract, Copper derived from soy protein is contained at a high concentration.

Further, since the soybean protein has a masking effect on the fresh odor of the oyster extract, the liquid food of the present invention contains the oyster extract,
It has excellent flavor. In addition, this makes it possible to increase the content of the oyster extract in the liquid food while preventing the odor of the oyster extract from becoming a problem, so that the liquid food has a larger amount of useful components derived from the oyster extract. Can be contained. For example, in addition to zinc, a large amount of taurine or the like having a lipid improving effect can be contained.
