Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to capsules containing kelp extract, and more specifically, a water-in-oil emulsion in which an aqueous solution of kelp extract extract is dispersed in edible oil and fat is encapsulated into soft capsules. This invention relates to capsules containing kelp extract.

(Prior Art) Kelp has been widely used as a natural seasoning agent and as a health food. Especially in recent years, as various components contained in kelp have been clarified, its efficacy has been newly discovered. Attention has been paid. For example, laminarin contained in kelp has a blood pressure-lowering effect, and sodium alginate, also contained in kelp, is known to have the effect of suppressing increases in blood cholesterol levels. In addition, kelp is rich in fucodine, which has the effect of preventing cholesterol from adhering to blood vessels, various vitamins including vitamin A, and essential minerals such as potassium, calcium, and iodine. It will be done. Additionally, it has recently been reported that kelp has anticancer effects.

However, since kelp has a unique odor and taste, it is not suitable for regular consumption. Powders and liquid extracts are already available on the market, which are made by extracting the above-mentioned active ingredients from kelp and adding vitamins, etc., but they still have a strong taste and odor peculiar to kelp. Since the odor is noticeable when used as an extract, the conventionally known kelp extract is also difficult to consume on a regular basis. It is difficult to remove the characteristic odor of kelp from the extract by adsorption deodorization using activated carbon or ion exchange resin, boiling, masking, or the like.

(Purpose of the Invention) As a result of intensive research to obtain a kelp extract that does not have the characteristic odor of kelp and is easily edible, the present inventors have discovered a method of dispersing an aqueous solution of kelp extract in edible fats and oils. ,
By forming a water-in-oil emulsion and encapsulating it with an edible film, capsules containing kelp extract that are substantially free of kelp ingredients and oil odor and can be easily eaten can be obtained. Furthermore, we have discovered that it is possible to obtain nutritionally enriched kelp extract-containing capsules by adding vitamins or adding edible fats and oils with a high vitamin content to the edible fats and oils as needed, This led to the present invention.

That is, an object of the present invention is to provide a kelp extract-containing capsule that is free from kelp ingredients and oily odor.

(Structure of the Invention) The kelp extract-containing capsule according to the present invention is characterized in that it is formed by covering a water-in-oil emulsion containing kelp extract, in which an aqueous solution of kelp extract is dispersed in edible oil and fat, with an edible film.

The aqueous kelp extract solution used in the present invention is prepared by adding edible kelp, such as Honey kelp, Naga kelp, Hosome kelp, Ma kelp, Oni kelp, Rishiri kelp, etc., to water, hot water, or It can be obtained by extraction with a mixed solvent of water and ethanol. Although the raw material kelp is not limited in any way, for example, Honey kelp, Rishiri kelp, and Ma kelp are preferable because of their high content of sugar derivatives and minerals.

The aqueous solution of kelp extract obtained by the above extraction process usually has a dilute concentration of active ingredients such as sugar derivatives and minerals when used as is, so it is preferably concentrated before being used for preparing an emulsion. If the concentration is too high, solid content will precipitate from the aqueous solution, so the concentration of evaporation residue in the extract aqueous solution is usually 45% or less, preferably 35-4%.
Concentrate to 0% range. Note that the kelp extract extract aqueous solution may be partially deodorized and decolorized using an ion exchange resin or the like before concentrating it.

In order to emulsify the aqueous solution of kelp extract, the aqueous solution of kelp extract may be mixed and dispersed in edible fats and oils containing an emulsifier and emulsified according to the usual method for preparing water-in-oil emulsions.

The edible fats and oils used here are not particularly limited, and examples include safflower oil, corn oil, soybean oil, wheat germ oil, rapeseed oil, peanut oil, sunflower oil, sesame oil, cottonseed oil, evening primrose oil, and rice oil. Can be mentioned. Also, regarding emulsifiers, if they are approved for use as food additives,
It is not particularly limited and may be appropriately selected from glycerin fatty acid ester, sodium chondroitin sulfate, sucrose fatty acid ester, sorbitan fatty acid ester, soybean phospholipid, and propylene glycol fatty acid ester, but with low viscosity,
In order to obtain a stable emulsion, it is preferable to use sucrose fatty acid ester and glycerin fatty acid ester in combination.

In the water-in-oil emulsion containing kelp extract used in the kelp extract-containing capsule of the present invention, it is preferable that the above-mentioned vitamins such as tocopherol are contained in the kelp in small amounts in the oil and fat. It is added to supplement the vitamins that are lacking in kelp extract and to further enhance the effects of kelp extract.

The edible coating for covering the water-in-oil emulsion containing kelp extract mentioned above, that is, the capsule, has gelatin, sodium alginate, cellulose derivatives, etc. as its main ingredients, but capsules are preferably used. Gelatin is used because it has excellent sticky properties and is commonly used for food.

In order to adjust the hardness of the capsule, an appropriate amount of plasticizer such as glycerin or sorbitol is usually added to the edible coating, and if necessary, a light-shielding agent, preservative, reinforcing agent, pigment, or Flavors etc. may be added.

The water-in-oil emulsion containing kelp extract can be coated with the above-mentioned edible film by a conventionally known method of encapsulating a lipophilic substance in soft capsules. for example,
A liquid composition for forming a capsule film such as gelatin is spread thinly, cooled and gelled to form a sheet, a water-in-oil emulsion containing kelp extract is sandwiched between the sheets, and pressed from both sides with a mold. and encapsulating the emulsion in a capsule,
A punching method that combines sheets and punches them out into capsules;
Alternatively, a dripping method is used to produce a so-called seamless capsule by ejecting a liquid composition for forming a capsule coating from the outside of a double nozzle and an emulsion from the inside thereof and releasing them into a cooling solvent. are representative examples.

(Effects of the Invention) According to the kelp extract-containing capsule of the present invention obtained as described above, there is not only the odor peculiar to kelp but also the odor peculiar to the oil and fat used to emulsify the kelp extract extract aqueous solution.
Reluctance due to smell when eating is eliminated. Also, since it is a capsule, it is easier to take orally than powder or liquid.

Furthermore, by adding vitamin E or/and vitamin F to the fats and oils in the kelp extract-containing capsule of the present invention, if the above-mentioned vitamins lacking in the kelp extract are supplemented, laminarin, alginic acid, or fucoidan contained in the kelp extract can be added. Combined with useful ingredients such as various useful sugar derivatives and minerals, higher effects can be expected.
