ABSTRACT:
TECHNICAL FIELD
The present invention relates to a food containing oil and/or fat. In particular, the present invention provides foods, though which are ingested, which are hardly accumulated as body fat, are easily utilizable as energy, and contribute to the storage of stamina at the time of fatigue. Further, the present invention provides foods with excellence in the oxidation stability of oils and/or fats contained therein and excellent in eating-feeling such as dissolution in the mouth.
BACKGROUND ART
Humans take in a source of necessary energy mainly from sugars and lipids, but have surplus calories in the modern dietary habits under the present circumstances. In particular, lipids have high calorie value and are regarded as a factor for facilitating obesity upon surplus intake to cause adult diseases. However, there are few lipids which are effective in inhibiting the accumulation of body fat and in more positive utilization as energy and are excellent in stability and eating-feeling.
JP-A 8-60180 describes that a fat composition comprising diglycerides containing middle- and long-chain aliphatic groups has a weak but inhibitory effect on accumulation of body fat.
JP-A 5-168142 discloses a diglyceride containing two long-chain aliphatic groups and utilizes it as a bloom inhibitor for chocolate.
DISCLOSURE OF THE INVENTION
Focusing on the characteristics in metabolism of nutrition on oils and/or fats, the present inventors made extensive study for the purpose of providing foods containing oils and/or fats, in the case of which are ingested into the body, are hardly accumulated as body fat, are utilizable more positively as energy, contribute to the storage of glycogen in the liver and muscle to achieve effects such as recovery from fatigue, supplement of nutrition and increase of stamina at the time of exhaustion of physical strength, at the time of fatigue and at the time of exercise, are excellent in the oxidation stability of oils and/or fats contained therein, and are excellent in eating-feeling such as in dissolution in the mouth. As a result, the present inventors found that partial glycerides derived from specific middle- and short-chain aliphatic acids are advantageous oils and/or fats in that they are easily utilizable as energy as described above, their accumulation as body fat can be easily controlled, and further they are excellent in eating-feeling and oxidation stability, and the present invention was thereby completed.
The present invention relates to foods comprising at least 0.5% by weight of a partial glyceride derived from a C
2-10
aliphatic acid. The number of carbons of the aliphatic acid is preferably 8 to 10.
The partial glyceride is preferably a diglyceride. More preferably, at least one of the two aliphatic acids constituting the diglyceride is a C
8-10
aliphatic acid, or at least one of two aliphatic acids constituting the diglyceride is a C
10
aliphatic acid, or both of the two aliphatic acids constituting the diglyceride are C
8-10
aliphatic acids. The partial glyceride is preferably capric acid diglyceride.
The foods preferably comprise 0.5 to 85% by weight of the partial glyceride.
Other preferable foods are those wherein the partial glyceride is a diglyceride, at least one of two aliphatic acids constituting the diglyceride is a C
10
aliphatic acid, and at least 4.0% by weight of this partial glyceride is contained.
The foods are preferably in the form of drinks or oral administration agent.
Further, the present invention relates to foods having the whole or a part of oils and/or fats in the fat-containing foods replaced by a partial glyceride, wherein this partial glyceride is derived from a C
2-10
aliphatic acid and the content of this partial glyceride in foods is particularly at least 0.5% by weight for oral administration.
Those who take in the foods of the present invention are supplemented with energy. Further, accumulation of body fat is inhibited in those who have taken in the foods. The partial glyceride is easily consumed as energy, and hardly accumulated in internal organs and adipose tissues. That is, glycogen is not consumed and readily stored. Accordingly, storage of glycogen is improved. This effect is more significant particularly, if at least 0.5% by weight of oil and/or fat contained in the foods is substituted by the partial glyceride.
When the foods of the present invention are ingested, as compared with no ingestion of the foods, fats other than glycogen are predominantly consumed thereby significantly reducing the decrease of glycogen.
In the view of the significant effect, besides the above-mentioned action and effect, it is suggested that the partial glyceride may inhibit the accumulation of other oils and/or fats (adiposes) in internal organs or adipose tissues, or may promote the consumption of accumulated fats.
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention is described in detail.
In the present invention, the partial glyceride includes monoglycerides and diglycerides. However, C
2-10
monoglycerides usually taste bitter etc. It may be necessary, when the C
2-10
monoglyceride is used as foods, that they should be formed into foods making use of the flavor or that they should be used in combination with a masking agent for flavor. On the other hand, diglycerides taste less bitter, so they can be applied to a wide variety of foods, and for this reason, the foods preferably contain a large amount of diglycerides rather than a large amount of monoglycerides.
The aliphatic acid mentioned above is a C
2-10
aliphatic acids such as acetic acid, butyric acid, caproic acid, caprylic acid and capric acid. If the number of carbon atoms therein is low, peculiar flavor tends to be generated. Therefore the peculiar flavor needs a masking agent or needs a suitable foods for its unique flavor. And then, C
8-10
aliphatic acids with weak flavor are more preferable because of application to a wide variety of foods. Particularly, one of the two aliphatic acids of the diglyceride is preferably a C
8-10
aliphatic acid, especially preferably a C
10
aliphatic acid, and both of them are more preferably C
8-10
aliphatic acids and most preferably C
10
capric acid diglyceride.
The foods referred to in the present invention are the modes of foods containing oils and/or fats, which are ready to be eaten. The content of the partial glyceride in the foods is 0.5% by weight or more, preferably 1% by weight or more, more preferably 2% by weight or more, most preferably 4% by weight or more, as compared with the foods. That is, comparatively high calorie foods containing at least 0.5% by weight of oils and/or fats are significant in the effect of the present invention.
Ingredients other than the partial glyceride used in the present foods may be any ingredients being usable for food.
Examples of the present foods include baked confectionery such as cookies and biscuits, fried cakes such as potato chips, cakes, ice creams, meats such as sausages and hamburgers, stews, fried foods such as fries and tempuras, and drinks such as juices and nutrition drinks. Further, the foods maybe creaming powder etc. insofar as the foods are placed in coffee or tea and contained in a necessary amount. Similarly, they may be dressings and mayonnaise on vegetables etc. satisfying a necessary amount in use, or margarine and fat spreads on breads etc. satisfying a necessary amount in use.
The foods of the present invention, into which the partial glyceride has been incorporated, are hardly accumulated as body fat and are easily converted into energy very rapidly. Further, it is believed that because this action is preferentially brought about, the foods also contribute to e.g. the maintenance of stamina by keeping glycogen in the liver and muscle. Accordingly, the foods are very effective in supplement of nutrition, recovery from fatigue and increase of stamina at the time of fatigue, at the time of reduction of physical strength, and before, during and after exercise.
The foods of the present invention are preferably in the form of
