Abstract

<P>PROBLEM TO BE SOLVED: To provide a chitosan-containing assistant food exhibiting sufficient effects of the chitosan and capable of heightening the efficiency of absorption thereof in the body. <P>SOLUTION: The chitosan-containing assistant food is obtained by forming a mixed powder of a water-soluble chitosan powder and an expandable powder into a tablet, granule, capsule or powder shape. As a result, the water-soluble chitosan powder is gradually dissolved in water while the expandable powder gradually generates foam of carbon dioxide gas in the body. The aqueous solution of the chitosan powder is gradually absorbed in the body according to the gradually progressing foaming. Therefore, the chitosan dissolved in the water is accurately ingested and the absorbing efficiency of the chitosan taken into the body is extremely heightened because the aqueous solution of the chitosan is absorbed in the body according to the foam-generating phenomena over a long time. Further, the diet is carried out by the feeling of fullness caused by the foaming to cause diet effects. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a chitosan-containing supplement that can effectively take water-soluble chitosan.

Supplemental foods containing chitosan are attracting attention as one of the health foods. Chitosan is a naturally-occurring nitrogen-containing polysaccharide and is known as a kind of water-soluble dietary fiber. As its utility, physiological functions such as improvement of cholesterol, inhibition of fat absorption, suppression of increase in blood pressure, improvement of intestinal metabolism and the like are expected. As described above, it is known that chitosan having various advantages is made into a form of water-soluble chitosan-containing granules from the viewpoint of storage stability and portability.

  However, if the chitosan-containing granule or an aqueous solution thereof is taken into the body as it is, chitosan is ingested by the same digestion phenomenon as normal foods, so the original utility of chitosan and high absorption efficiency into the body are sufficient. There is a problem that it cannot be secured.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a chitosan-containing supplement that sufficiently obtains the effects of chitosan and increases the absorption efficiency into the body.

  In order to achieve the above object, the chitosan-containing supplement of the present invention uses a mixed powder containing a water-soluble chitosan powder and an effervescent powder as a main ingredient, and these are any of tableted, granulated, capsule, and powdered forms. The gist is that the total amount of water-soluble chitosan powder and foamable powder is 40% or more.

  The chitosan-containing supplement is dissolved by moisture in the stomach. At this time, the water-soluble chitosan powder gradually dissolves in water while the foamable powder gradually generates carbon dioxide bubbles. Along with such gradually progressing foaming, an aqueous solution of chitosan powder is gradually absorbed into the body. Therefore, since the aqueous solution of chitosan powder is absorbed into the body along with the generation of bubbles over a long period of time, the water-solubilized chitosan is surely ingested, and the absorption efficiency of chitosan taken into the body can be significantly increased. In particular, since water-soluble chitosan is made into a tablet, granule, capsule form from the powder state, or taken into the body in powder form, the solubility of chitosan that progresses with foaming is good and absorbable into the body It is suitable for improvement. In addition, since foaming is sustained in a wide region from the stomach to the intestine, the absorption of chitosan into the body is efficiently performed in such a wide digestive organ.

  Furthermore, a feeling of fullness is maintained by the foaming of the foamable powder, so that the appetite is suppressed, the food saving is progressed, the calorie intake is reduced, and the diet effect is produced. Since the above-mentioned fullness is felt when the supplements swallowed in a small state are foamed, the fullness can be clearly expressed, and the progress of the above-mentioned savings is made favorable.

  Next, the best mode for carrying out the chitosan-containing supplement of the present invention will be described.

  The basic constituents of the chitosan-containing supplement of the present invention are water-soluble chitosan powder and foamable powder.

  First, formation of water-soluble chitosan powder will be described. Chitosan is obtained by changing the acetyl group of chitin contained in crab shells and the like to 60% or more amino group and extracting and purifying it into a powder state.

  Chitosan is inherently insoluble in water, so a water-solubilization treatment is first performed. Therefore, after chitosan is suspended in water and swollen, an organic acid such as malic acid, acetic acid, lactic acid, citric acid, and vitamin C is added and stirred to give chitosan solubility in water to obtain a chitosan aqueous solution. Next, water-soluble chitosan powder is produced by a so-called spray-drying method in which the chitosan aqueous solution is spray-dispersed in hot air, and the spray droplets dries moisture during flight.

  That is, in order to produce a water-soluble chitosan powder, a chitosan aqueous solution is prepared, and then this chitosan aqueous solution is made into powder. First, 20 g of chitosan having a molecular weight of 50,000 to 60,000 and a deacetylation degree of 70 to 80% was suspended in 1000 cc of water and swollen. Thereafter, 16 g of malic acid was added to the water in which chitosan was suspended and stirred to prepare an aqueous solution of chitosan. Next, 100 g of dextrin was added to the chitosan aqueous solution and stirred to prepare a solution before micronization. The acid is not particularly limited, but an organic acid is preferable. As the organic acid, acetic acid, lactic acid, citric acid, succinic acid, maleic acid and the like can be used in addition to the malic acid. In order to obtain sufficient solubility of chitosan, the amount of the acid is desirably equal to or more than the neutralization equivalent with respect to the amount of glucosamine in chitosan.

  Next, the chitosan aqueous solution was spray-dispersed in hot air using a spraying device, and water-soluble chitosan powder was produced by a so-called spray-drying method in which water droplets were dried during flight.

  On the other hand, the foamable powder is obtained by mixing a sodium hydrogencarbonate (bicarbonate) powder and a citric acid powder.

  The mixed powder of the water-soluble chitosan powder and the foamable powder is formed into a tablet of, for example, 300 mg / grain. As an example, water-soluble chitosan powder 150 mg / grain (weight ratio 50.0%), sodium bicarbonate powder 75 mg / grain (weight ratio 25.0%), citric acid 37 mg / grain (weight ratio 12.3%) ).

  Furthermore, as a component constituting the remaining weight part, starch is used as a binder material for obtaining adhesive bonding between the water-soluble chitosan powder and the foamable powder, and glycerin fatty acid ester powder and fine silicon dioxide powder are used. It is used as a mold release agent from a mold for tableting, and a lemon flavor is further used. The powder of the component constituting these remaining parts by weight is added to the mixed powder composed of the water-soluble chitosan powder, sodium hydrogencarbonate powder, and citric acid powder, which is distributed as described above, to obtain a powder before tableting. Note that the lemon flavor can be eaten comfortably, and can be replaced with other flavors according to consumer preference.

  The powder before tableting is supplied to a tableting device to form a granular chitosan-containing supplement.

  In addition to the above tableting molding, powders before tableting molding were formed into granules, those encapsulated in capsules, and powders before tableting molding were directly placed in storage bags or plastic containers were prepared.

  The blending weight of each of the above components is not limited to the above numerical values, but the blending ratio (weight) of water-soluble chitosan powder, sodium bicarbonate, and citric acid, which are the main components for achieving the purpose as a supplement. Ratio) can be set as follows: That is, the water-soluble chitosan powder is preferably at least 30% or more, more preferably 35% or more. Furthermore, if it is 30 to 90%, it is more preferable, and the most preferable is 40 to 85%. The sodium hydrogen carbonate powder is preferably 5 to 40%, and the citric acid powder is preferably 5 to 20%. By adjusting the blending ratio in this way, the amount of chitosan and the foaming time can be adapted to the user's constitution, health condition, etc., and supplementary foods according to the consumer's various demands can be provided to the market.

The chitosan-containing supplement according to the present invention is formed into a round tablet having a weight of, for example, 300 mg / grain. And the compounding weight per grain of each structural component was as follows. Each numerical value is a weight ratio.
80% water-soluble chitosan powder
Sodium bicarbonate powder 6%
Citric acid powder 12%
Glycerin fatty acid ester 2%
The total of the water-soluble chitosan powder, sodium hydrogen carbonate powder and citric acid powder is preferably 40 to 98%, more preferably 50 to 95%.

  Four types of powders having the above blending weight were sufficiently mixed until uniform, and then supplied to a tableting device to obtain a granular supplement.

  The above food shape is a round tablet, but other shapes include granules, capsules, and pre-tablet powder in storage bags or plastic containers. Etc. were produced.

  As a result of tasting the supplementary foods with a plurality of parties, it was confirmed that a feeling of fullness extending for about 2 to 3 hours was sustained by foaming in the digestive organs. Therefore, as described above, the intake of chitosan with good absorption efficiency has progressed, and depending on the health status of the savvy parties, such as improvement of cholesterol, inhibition of fat absorption, suppression of blood pressure increase, improvement of intestinal metabolism, etc. It became clear that various physiological functions can be expected.

  Water-soluble chitosan powder is expected to be widely welcomed by consumers as a new supplement that can be absorbed into the body efficiently by effervescent powder to promote health and provide a diet effect due to fullness.
