Description

  The present invention relates to a film-like food containing a supplement component and a method for producing the same.

Various foods have been developed as film-like foods, and there is a film made of starch known by the name of oblate in the old days. In addition to starch, those containing gelatin, pullulan and sodium alginate as main components are also known. In recent years, various food packagings and edible films in which supplements, flavors and the like are held on the film itself have been proposed (Patent Documents 1 and 2).
JP 2004-222663 A JP 2004-248665 A

Up to now, unstable ubiquinone, α-lipoic acid, catechin, oil-soluble vitamin C derivatives, and retinoids have been formulated as hard capsules or soft capsules molded with gelatin or the like as means for providing them as food stably. These preparations had to be carried in containers such as pill cases and had problems such as requiring water for consumption.
On the other hand, since a thin film can be easily dissolved in the mouth and ingested without the need for water, it is considered that various components are supported on the edible film. Some edible films that have sweeteners, flavors, etc., have been put to practical use, but some supplement ingredients are unstable with respect to humidity and temperature, so the ingredients are more stable. There is a need for film foods that can be made.
The present invention is intended to provide a film-like food that can stably retain the supplement component and is easy to ingest.

In the film-like food of the present invention, the target supplement component is included (included) in cyclodextrin (CD), and the resulting CD inclusion is mixed into the film-forming material and formed into a film of a desired thickness. Or a CD inclusion body is applied to an edible film made of a film forming material.
In the present invention, examples of supplement components include ubiquinone (coenzyme Q10), α-lipoic acid, catechin, carnitine, theanine, citric acid, vitamin B group, vitamin E, oil-soluble vitamin C derivatives, minerals, and retinoids. It is done.

  The film-like food of the present invention improves the affinity with various film-forming components by enclosing the supplement component with cyclodextrin, and is securely held in the film, and is stable and thin in any thickness. It can be made into a film and can also be a laminated film of layers containing various components. Thereby, it is easy to carry and has the advantage that water or the like is not required for ingestion, and various components can be ingested at once by stacking various components.

Many of the supplement components have poor solubility, dispersibility, miscibility, and the like with respect to the film-forming material, and film formation is difficult. Ubiquinone (coenzyme Q10), α-lipoic acid, catechin and the like, which are supplement components of the present invention, are hydrophobic powders, and oil-soluble vitamin C derivatives and retinoids are hydrophobic liquids. Although there is a problem in the miscibility, etc., it can be made into a powder that is easily compatible with water by inclusion in cyclodextrin (CD).
The inclusion effect by cyclodextrin may be due to the physical properties of cyclodextrin itself, but many of the above-mentioned supplement components are derived from natural products consisting of various components, and even synthetic products contain by-products. However, it is considered that there are effects such as separation of components that are not included by inclusion of cyclodextrin and components that are not included, and removal of components that inhibit film formation and the like. From these facts, the supplement component can be used in the present invention without being limited to the above by utilizing the selective effect of cyclodextrin.

The cyclodextrin can be selected from α-CD, β-CD, and γ-CD depending on the supplement component, and is preferably β-CD or γ-CD.
In addition, it may be selected based on affinity with the film-forming component, miscibility, or the like, or α-CD may be selected from the viewpoint of water solubility.
Cyclodextrins may be used in combination with the above. Inclusion is usually performed for each supplement component, but two or more components may be combined.

Examples of film-forming components include starch, pullulan, arabinoxylan, guar gum degradation products, sodium alginate, carrageenan, agar, pectin, polysaccharides such as cellulose, and peptide substances such as gelatin, silk degradation products, and casein degradation products. What is used for an edible film can be used. These can be used alone or in combination of two or more.
In the present invention, preferably, starch, sodium alginate, carrageenan, pectin, cellulose and other polysaccharides, gelatin, silk degradation product, casein degradation product and the like can be mentioned.
The film-forming component can be molded thinly to take advantage of the properties as a film, does not adhere to the oral cavity when eaten, dissolves at an appropriate speed, and sufficiently retains the desired supplement component In addition, it is selected and used in consideration of satisfying various requirements such as being able to be performed and having appropriate strength.

In addition to the above, components usually used in this type of field can be used as film forming components. For example, calcium ions for sodium alginate, lactitol, maltitol, erythritol, mannitol, etc. as a film plasticizer, polysaccharides, flavors, sweeteners, etc. as film strengthening agents may be included. In addition, a stable supplement component may be included even if it is not a CD inclusion body.
The film-forming material is prepared as an aqueous solution or aqueous dispersion containing the above components. As the film-forming material, alcohol, glycerol, surfactants and the like that can be used as food can be used.

The film-like food of the present invention may be a single edible film containing a supplement component, a laminate of such films, or a laminate with an edible film not containing a supplement component. There may be.
In forming a film-like food, a film having one supplement component inclusion is usually produced, but one film including two or more supplement component inclusions may be used.
In principle, a film-like food is made by applying a film-forming material made of starch or the like as an aqueous solution of appropriate concentration, thinly onto a smooth substrate such as a glass plate or a smooth plastic film, and drying to form a film. Created by. Industrially, for example, it is produced by a continuous production method such as applying a film molding material to the surface of a rotating drum having a smooth surface, drying it and winding it.
The supplement component CD inclusion body (hereinafter, simply referred to as “CD inclusion body” in some cases) is added to the film forming material as an aqueous dispersion.
Lamination of the film may be carried out as a film and then laminated with another film, or may be carried out by a method of winding up with another film at the time of winding.

Although the thickness of the film shape | molded is not specifically limited, It is good to set it as about 30-300 micrometers.
The thickness of the film is selected mainly by the strength and solubility of the film. In the case of a laminated film, a film-like food can be made thin by selecting a film having a surface layer that does not contain a supplement component and having strength.
In addition to strength, the film that does not contain a supplement component acts as a barrier between the upper and lower supplement component-containing films when laminated, and also has a role of blocking moisture, air, etc. by providing it on the outermost surface. You may let them. For example, since oil-soluble vitamin C remains reactive with iron ions even if it is included in cyclodextrin, a browning phenomenon occurs, but this phenomenon can be prevented by providing a barrier film.

  A method of holding the CD inclusion body on the formed film later can be performed by, for example, a method of spraying a dispersion liquid of the CD inclusion body at the time of film formation. The dispersion may contain a binder such as starch and an adhesive such as glycerol, or may be attached as a simple aqueous solution with the adhesive strength of the film itself during semi-drying. The film to which the CD inclusion body is attached may be laminated with a barrier film or the like.

Hereinafter, although the manufacture example and Example of this invention are shown, this invention is not limited to this.
Production Example 1 Preparation of an edible film containing no supplement components (barrier film)
While stirring, an appropriate amount of ion-exchanged water is added with starch, glycerin, and cellulose as film-forming components. The resulting mixed solution is heated to gelatinize to obtain a starch solution having an appropriate concentration and viscosity, and a sweetener solution and a fragrance are added to this solution to form a uniform coating solution. This coating solution is applied to a surface-smooth rotating drum. The edible film which does not contain a supplement component is obtained by peeling and drying the dried film.

Production Example 2 Preparation of edible film containing supplement CD inclusion body Add gelatin, glycerin, cellulose, heat-resistant supplement material, etc. as film forming ingredients while stirring to hot water heated to about 70 ° C., Stirring is stopped after the addition is complete. The obtained mixed solution is heated and gelatinized to obtain a solution having an appropriate concentration and viscosity, and defoamed. The defoamed gelatin solution is transferred to a heat-retaining kettle at a temperature of about 50 ° C., and while being stirred again, the supplement CD is dispersed in a sweetener, a dye solution, a heat-sensitive supplement material, an emulsified flavor, water or hot water. The body and the acidulant solution are sequentially added to obtain a uniform coating solution. The coating solution after addition of the acidulant solution is preferably pH 4 or higher. The coating solution thus prepared is applied to a rotating drum having a smooth surface, dried, and the dried film is peeled off from the rotating drum to obtain a film-like food containing a supplement component.

In the production of the film of Production Example 2, a film-like food containing each of ubiquinone, α-lipoic acid, catechin, oil-soluble vitamin C derivative, retinoids and the like can be obtained by changing the supplement component as a CD inclusion. . Moreover, the film-form foodstuff which apply | coated the coating liquid of the manufacture example 2 on the upper surface of the edible film obtained by the manufacture example 1 and dried and can laminate | stack can be obtained.
The production method of Production Example 2 is a method in which the CD inclusion body is mixed into the film forming material, but the supplement CD inclusion body liquid dispersed in water or hot water is sprayed on the surface of the film formed in Production Example 1 or It is possible to prepare a film-like food that is applied and retains a supplement component. A laminated film-like food may be obtained by laminating a barrier fill on the CD clathrate holding surface of the obtained film-like food.
In the above production example, the coating solution is not applied to the rotating drum, but applied to the surface of a plastic film such as a polyethylene terephthalate (PET) film, and then dried through a rotating drum for drying or a drying furnace to be edible. It is manufactured by a method of separating a film (film-like food).

Examples are shown below.
Each component shown in Table 1 is prepared in an aqueous solution for each formulation, and each formulation is combined to form a mixed liquid for film formation. The obtained mixture was applied to a smooth plastic sheet surface, dried and peeled to obtain an edible film (thickness: 100 μm) containing a catechin CD inclusion body.
Examples of the film-forming components are sodium caseinate in Example 1, modified corn starch in Example 2, pullulan in Example 3, and sodium alginate in Example 4.

The films obtained in Examples 1 to 4 have good moldability, strength, and solubility, and the CD inclusions indicate that any film-forming component can provide a good edible film.
The supplement component was replaced with catechin, and ubiquinone and α-lipoic acid were used to obtain the same results as above.

Next, the example which compared the edible film containing the supplement component which carried out CD inclusion and the non-inclusion supplement component is shown.
Each material shown in Table 2 was dissolved for each formulation to obtain a solution or dispersion, and these were combined to prepare a coating solution with an appropriate viscosity. This coating solution was applied to an OPP (oriented polypropylene) film surface and dried to a moisture content of 7% to prepare a film (thickness: 100 μm).

表３に示すとおり、ＣＤで包接したα−リポ酸を含むフィルムの方がＣＤで包接しないα−リポ酸を含むフィルムに比して、耐湿性、耐乾燥性に優れており、折り曲げ強度も優れていることがわかる。 About the obtained film, it investigated about the moldability, moisture resistance, and drying resistance.
The survey was conducted according to the following method.
Formability: Judgment was made based on whether or not the edible film formed on the OPP film by the above production method could be peeled off as a film.
Moisture resistance: 24 films of 22 × 33 mm were placed in a plastic case, and the degree of adhesion between the films after being treated in a constant temperature and humidity chamber (40 ° C., RH 70%) for 2 days was confirmed. The plastic case is a non-sealed container having a case inner dimension of 22 × 33 × 2.5 mm and having a take-out slit at the side end (the same applies hereinafter).
Drying resistance: 24 sheets of 22 × 33 mm films were put in a plastic case, and the brittleness after being treated in a constant temperature and humidity chamber (30 ° C., RH 32%) for 2 days was confirmed.
The results are shown in Table 3.

As shown in Table 3, the film containing α-lipoic acid clathrated with CD is superior in moisture resistance and drying resistance compared to the film containing α-lipoic acid not clad with CD. It can be seen that the strength is also excellent.

Took Comparative Example B1 5 times a day for 2 weeks. After that, based on the above criteria, the skin condition before and after use was subjected to a monitor test with respect to four items of moisture feeling, skin gloss, skin firmness, and blood color. None of the patients complained of physical abnormalities throughout the study period.
In Example A1, a clear skin quality improving action was recognized as compared with Comparative Example B1. The results are shown in Tables 4-7.

(2) Mental and physical improvement effects Two groups of 10 to 40-year-old female volunteers who complained of mental and physical decline were recruited in one group, and one group was given Example A2 (Film Supplement; Genki). Comparative Example B2 was ingested for 5 consecutive days for 2 weeks. Thereafter, based on the above criteria, a monitor test was conducted on the mental and physical conditions before and after use for three items: waking up, feeling tired during working, and feeling tired after working. None of the patients complained of physical abnormalities throughout the study period.

  As shown in Tables 4 to 10 above, the film supplement containing the CD inclusion body showed better results than the film supplement containing the non-inclusion component in terms of beauty and health. Moreover, the film supplement containing CD inclusion body did not adhere to each other film, or the film was not chipped when ingested, and a report from the panel that it was good in the oral cavity was also obtained.

  Substances that are unstable in the air, are insoluble in water and are difficult to disperse or dissolve in water, and are natural substances such as catechins. Even those that could not be included in the process of making an edible film include a sufficiently supplemented component that has been stabilized by using the inclusion body selectively included by the method of using cyclodextrin according to the present invention. A film-like food can be obtained.
