Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a supplement containing water-soluble dietary fiber, which is obtained from the endosperm or fruit water of coconut fruit (coconut) and is useful for treating or preventing hyperlipidemia.

[0002]

2. Description of the Related Art In recent years, dietary fiber has attracted attention as a health food. Dietary fiber includes water-insoluble dietary fiber and water-soluble dietary fiber, and the water-soluble dietary fiber has serum cholesterol lowering action, blood glucose level regulating action, intestinal regulating action and the like.

[0003]

However, there are still many unclear points about the serum cholesterol lowering effect of water-soluble dietary fiber, and when added to foods, the flavor, color, taste, texture, etc. of the foods can be improved. It could have an adverse effect. For example, guar gum, pectin, etc. are the most representative water-soluble dietary fibers, but their serum cholesterol-lowering effects are not always sufficient, and the flavor and texture of foods are deteriorated. There was a problem.

Therefore, an object of the present invention is to provide a dietary supplement having a good texture and an excellent action.

[0005]

Therefore, the present inventors have
As a result of research as part of industrial use of coconut, water-soluble dietary fiber obtained from coconut endosperm and / or fruit water has an excellent cholesterol-lowering effect as compared with guar gum and has a good texture. The present inventors have completed the present invention by finding that supplements can be obtained.

Coconut is a typical plant in the tropics, and coconut endosperm contains about 50% water, about 35% oil, protein, sugar and dietary fiber. BACKGROUND ART Oil obtained from coconut endosperm has been widely used as a food oil and a raw material for fats and oils in various industries, but until now, coconut has hardly been industrially used as a raw material other than a raw material for fats and oils. Here, coconuts are classified according to their morphological characteristics, and there are many varieties. Coconut, which is a raw material of the water-soluble dietary fiber used in the present invention, may be any variety and is not particularly limited, but a macapno variety, which is an abnormal endosperm differentiation / proliferation species, is a ratio of endosperm in coconut. Is larger than that of common species, and a large amount of water-soluble dietary fiber having a serum cholesterol-lowering effect is contained not only in the endosperm but also in fruit water, so that it is particularly preferably used.

[0007] As a method for extracting water-soluble dietary fiber from coconut endosperm and / or fruit water, for example, "Jour.

That is, coconut endosperm or fruit water is treated with any of enzymatic treatment, chemical treatment, physical treatment, or a combination of these treatments as appropriate to remove contaminants such as lipids, proteins, starches, and minerals, and further water. Insoluble dietary fiber can be removed to prepare a water-soluble dietary fiber containing mucus polysaccharide as a main component.

The water-soluble dietary fiber obtained as described above may be used after being purified, but it can usually be used as a crudely purified product, and the crudely purified product (hereinafter referred to as dietary fiber composition The content rate of dietary fiber in 50% by weight is preferably 50% by weight (hereinafter referred to as%) or more, and particularly preferably 70% or more by an enzyme-gravity method. If the dietary fiber content of the dietary fiber composition is less than 50%, a large amount of the dietary fiber composition must be added to the food in order to exert its physiological activity as a supplement for treating or preventing hyperlipidemia. However, if the amount added is large, the texture of the food may be impaired. Further, the effect of treating and preventing hyperlipidemia of dietary fiber is mainly due to the water-soluble dietary fiber, and therefore, the higher the content rate of the water-soluble dietary fiber in the dietary fiber composition, the more preferable, and the content rate of the water-soluble dietary fiber. The higher the value, the more the physiological activity can be expressed by adding a small amount of the dietary fiber composition, and the risk of impairing the texture of the food is reduced.

In the present invention, coconut endosperm and / or
Alternatively, the content of the water-soluble dietary fiber prepared from fruit water is about 1 to 40%, preferably about 5 to 30% in the food composition. If the content of water-soluble dietary fiber is too low, a large amount of food must be eaten in order to obtain the therapeutic or preventive effect on hyperlipidemia, and if the content is too high, the texture of food is impaired. There is a risk.

The food to which the water-soluble dietary fiber obtained from the coconut endosperm and / or fruit water is added is not particularly limited, and examples thereof include various drinks such as soft drinks, cocoa drinks, and bread. , Flour products such as cookies and biscuits, tablet-type and granule-type foods such as Ramune confectionery, and the like. In the present invention, bread, cookies, biscuits and soft drinks are particularly preferable.

INDUSTRIAL APPLICABILITY According to the present invention, it is possible to obtain a supplemental food useful for treating or preventing hyperlipidemia.

[0012]

The present invention will be described in more detail below with reference to examples, but the present invention is not limited to these examples. Example 1 A coconut (common seed) endosperm was placed in a mixer, and distilled water having the same weight as that of the endosperm was added and sufficiently stirred and mixed to form a slurry. This slurry was freeze-dried and ground in a mortar to obtain a dried coconut endosperm powder preparation. Chloroform / methanol (3: 1) 5 to 10 times by weight of this
The mixed solution was added, stirring and degreasing were performed for 60 minutes, and the residue was collected. This defatting operation was repeated 3 times to extract a crude dietary fiber fraction from the coconut endosperm. Next, the crude dietary fiber fraction is mixed with hot water (80 to 85 times) in a weight ratio of 5 to 10 times.
(° C) was added and stirred for 2 hours to extract water-soluble dietary fiber. This hot water extraction operation was repeated 3 times, and after the third extraction operation, 5 times by volume of methanol was added to the hot water extract to precipitate water-soluble dietary fiber and recover the precipitate, A water-soluble dietary fiber fraction was obtained. Further, in a 5 mM phosphate buffer solution (pH 7.5), a water-soluble dietary fiber fraction 1 g
About 5mg of alkaline protease (Kao Corporation)
Deproteinization treatment was performed by allowing 20 to 50 units / mg of the product to act at 40 ° C. for 2 hours. After the completion of the deproteinization treatment, hot methanol was added to inactivate the enzyme to precipitate water-soluble dietary fiber. This precipitate was collected, washed with ethanol and ether, and then vacuum dried. Finally, this fiber fraction was further pulverized to obtain a dietary fiber composition having a particle size of 48 mesh or less. In this way, from about 6 kg (wet weight) of coconut endosperm to 8
6.5 g (dry weight) of coconut dietary fiber composition was obtained. The yield was 6.78%. The water-soluble dietary fiber content in the coconut dietary fiber composition was 80% or more (enzyme-gravity method), and the residual protein amount was less than 10% (micro Kjeldahl method).

Example 2 After 17-week-old male SD rats were preliminarily fed with a basic diet, the diet was changed to a cholesterol-loaded diet containing 1% cholesterol and 0.25% sodium cholate to start the experiment. Raised for a week. Dietary fiber was added at 5% in the cholesterol-loaded diet. The feed group was a group containing water-soluble dietary fiber obtained from the coconut endosperm prepared in Example 1, a group containing guar gum (trade name: Sunfiber, Taiyo Kagaku Co., Ltd.) for comparison, and cellulose as a control. There were 3 groups of powder (Oriental Industry Co., Ltd.), and each group had 7 animals. Blood was collected on the start day of the experiment and one week after the start of the experiment, and the total serum cholesterol level was measured. The measurement results were expressed as comparative values with the serum total cholesterol value at the start of the experiment as 100, and (average value ± measurement error) is shown in FIG. No difference was observed between the groups in food intake and body weight change during the test period. As shown in FIG. 1, a significant decrease in serum total cholesterol was observed in rats fed with water-soluble dietary fiber obtained from coconut endosperm. As described above, it can be seen that the dietary fiber obtained from coconut endosperm has a remarkable inhibitory effect on serum total cholesterol elevation.

Example 3 Bread containing coconut water-soluble dietary fiber and made of the ingredients shown in Table 1 was prepared.
