Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to stevia paper and stevia fiber made from stevia, which is used for building interior finishing materials, food and food packaging materials, and other medical, hygiene and daily products. It relates to these manufacturing methods.

[0002]

2. Description of the Related Art Stevia is a plant belonging to the Asteraceae family which originates in Paraguay, South America. It has been known that stevia has sweetness and is used as a sweetening additive for foods such as soft drinks.

[0003] In recent years, attention has been paid to the antibacterial properties of stevia, the detoxifying effect of histamine which is a causative substance of gastric ulcer and allergy, the antioxidant activity, other medicinal effects and the activating effect of living bodies, and many inventions have already been known. (Eg, Japanese Patent No. 1979472 (Surgical skin treatment agent), Patent No. 19)
No. 84018 (internal solution for digestive system disease treatment and manufacturing method) and the like. ) By the way.

[0004]

By the way, when stevia is conventionally used, a stevia concentrate is obtained by squeezing leaves or stems, or a stevia extract is obtained by hot water extraction from leaves or stems. Then, the squeezed stevia after the treatment such as squeezing or hot water extraction (hereinafter referred to as “squeezed scum”).
It was considered useless and had no use, and was disposed of by incineration or underground burial.

However, attention has been paid to the above-mentioned medicinal effects of stevia, and it has been used in health drinks or medicines on the recent health food boom, and the marble of stevia is generated at present. . This marc,
The disposal involves costs including transportation costs, and when incinerated, secondary problems such as the generation of CO ₂ also arise.

[0006] The present invention thus makes effective use of the stevia marc, which is troubled by its disposal, and conversely, although the extract of stevia is extracted, the antibacterial property of the stevia remaining in the marc is removed. It is an object of the present invention to make effective use of medicinal ingredients such as detoxification and to achieve synergistic and complete use of stevia. As a result, a large amount of stevia can be consumed without hesitation to promote human health, and also to solve secondary environmental problems.

[0007] The present inventors have intensively researched and developed techniques for using stevia marc from various viewpoints in order to make effective use of the marble and to reduce the cost required for its disposal. As a result, it is not efficient to extract the remaining medicinal components from the pomace extracted from the medicinal components of stevia, and the pomace, especially the stems and roots, contain much cellulose. We paid attention to.

[0008] As described above, the present invention is an antibacterial agent which effectively utilizes stevia, especially stalks and roots, which have never been considered or utilized, and which remains in the stevia marc. It is an object of the present invention to synergistically utilize the drug efficacy such as detoxification.

[0009] By the way, conventionally, not only the leaves of Stevia but also the stems and roots are squeezed and the extract is used as described above.
Since the amount is larger than the leaves, there is a lot of unused and unused parts that are not squeezed. Overseas, stems and roots are incinerated in large quantities, and domestically, only small amounts are used as fertilizers except for squeezing and used. The present invention is not only for the above-mentioned marc, but also for unused, discarded in large quantities, and especially for effective utilization of stems and roots. Without squeezing,
It goes without saying that drying treatment, pulverization, etc. may be used as they are.

From the above, specifically, pulp is obtained from cellulose contained in stevia or stevia marc to obtain paper (stevia paper), or fiber (stevia fiber) is obtained from this cellulose. They are intended to contribute to healthy living by effectively utilizing these materials for interior finishing materials for construction, packaging materials for food and food, and other medical, hygiene, and everyday products.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described based on embodiments with reference to the drawings. First, as an example of the stevia paper (paper made from stevia) according to the present invention,
Example 1 will be described. The stevia paper according to Example 1 uses at least one part including at least the stalk (the stalk contains a large amount of cellulose) among three parts of the stevia leaf, stem and root as a raw material (stevia raw material). The material is squeezed, stevia pulp is manufactured using stevia marc remaining after the concentrated liquid is extracted, and the stevia pulp is mixed with wood pulp obtained from stevia pulp or stevia pulp and ordinary wood. (Stevia paper).

The structure of the stevia paper will be described below with reference to FIG. One or more portions including at least the stem among the three portions of the stevia leaf, stem and root are used as a raw material (stevia material). Now, a case in which stevia paper is manufactured including all three parts of leaves, stems and roots will be described. Stevia leaves, stems, and roots are each dried, and then finely pulverized to about 0.1 to 1 mm with a pulverizer (mixer) to produce pulverized stevia. Alternatively, stevia leaves, stems and roots are each dried, then 1-3 cm
It is pulverized to a small degree, loosened with a roller, and crushed into a thread to produce a pulverized stevia.

Next, the pulverized stevia (pulverized substance pulverized by a pulverizer and / or pulverized pulverized substance) is put into a melting vessel, and an appropriate amount of water is added thereto and heated to elute the medicinal components of stevia. Obtained stevia solution is obtained. Then, the stevia solution is squeezed by, for example, a squeezing device having a structure in which pressure is applied to a filter attached to one end opening of the cylinder by a piston sliding in the cylinder, and a concentrated solution from which the medicinal component of stevia is extracted. Can be obtained. This concentrated liquid is further subjected to fermentation treatment and the like, and its medicinal components are used for medicines, health foods and the like.

(Example 1) By the way, a large amount of cellulose is contained in the stevia marc remaining after the concentrate is squeezed out. The stevia paper according to the first embodiment is a paper that is manufactured using the marc included in the marble of the stevia. The manufacture of the stevia paper will be further described.

[0023] Stevia marc is taken out of the squeezing device, put into a digester, and mixed with an alkaline liquid such as caustic soda in the digester for digestion. Then, paste-like pulp (stevia pulp) is obtained. The thus obtained stevia pulp and water, or stevia pulp, woody or regenerated pulp and water (see the imaginary line in FIG. 1) are mixed, and the stevia pulp is mixed in a normal papermaking process, that is, in a mold. A mixture of pulp and water is poured into the pulp, and the mixture is sieved with a paper net placed in a mold to make paper, and stevia paper is obtained.

(Embodiment 2) Next, Embodiment 2 will be described as stevia paper according to the present invention. In Example 1, although the concentrated solution was squeezed out, the stevia marc remaining after the squeezing was mixed with an alkaline solution to produce stevia pulp, and the paper was made.
The stevia paper according to Example 2 was manufactured by mixing the stevia marc of Example 1 with dry, loosened, woody or recycled pulp without producing such stevia pulp. It consists of

Example 3 Next, Example 3 will be described as stevia paper according to the present invention. In Examples 1 and 2 of the stevia paper, the leaves, stems and roots of the stevia were squeezed, the concentrated solution was squeezed out, and then the pomace was used. However, as described in the section of "Problems to be Solved by the Invention", the concentrated liquid is discarded in a large amount without being squeezed, and especially stems and roots are dried after being collected, crushed, or shredded. After pulverization, the pulverized stevia may be loosened with a roller to produce a pulverized stevia, which may be directly mixed with a wood-based or recycled pulp to make paper.

FIG. 2 shows a stevia paper according to Example 3. FIG. 2 (a) shows a pulverized stevia obtained by pulverizing stems and roots to about 10 μm to 1 mm. Stevia paper made by mixing with wood pulp. FIG. 2 (b) shows a crushed material obtained by crushing stems and roots to about 10 μm to 1 mm and a crushed stevia obtained by shredding and crushing to about 1 to 3 cm with a roller, and mixing with woody pulp. The paper is stevia paper.

Therefore, in FIG. 2 (a), the stems and roots are added to a regular paper dough 1 made of ordinary woody pulp by 10 μm.
This shows a state where the stevia crushed material 2 crushed to about m to 1 mm is mixed. Also, in FIG. 2 (b), in addition to the ground stevia 2,
This shows a state in which the pulverized stevia 3 formed by shredding and pulverizing to about cm and loosening with a roller is mixed.

The stevia papers according to the present invention of Examples 1 to 3 are stuck on the surface of a building interior finishing material such as a floor material, a wall material, a ceiling material, or a layer is formed in these building interior finishing materials. Used as a material (structure woven into layers). By using the stevia paper as the interior material for the building in this way, a large amount of stevia marc generated is effectively used. When used as a building interior material, it is used with a decorative print attached thereto, but may be subjected to a fire prevention treatment or the like.

Further, the antibacterial and medicinal components of stevia or stevia marc remaining in stevia marc act to obtain a building interior finishing material with enhanced antibacterial properties, and have antibacterial properties, antifungal properties, etc. A rich, extremely healthy and comfortable home is obtained. In recent years, it is thought that allergies occurring in newly constructed houses using synthetic building interior finishing materials are attributed to chemical substances contained in the finishing materials. However, in the building interior finishing materials using stevia paper of the present invention, stevia is used. Due to the histamine detoxifying effect of the compound, it exerts an allergy suppressing effect.

Stevia paper is used not only for interior finishing materials of buildings, but also for its antibacterial properties, and is used for packaging materials for medicines, medical equipment, etc., packaging materials for foods and foods, paper diapers,
It is highly useful for sanitary products such as sanitary products and other daily products.

In Examples 1 to 3, one or more of the three parts of stevia leaves, stems and roots, including at least the stems, are used as raw materials. A material containing all three parts may be used as a raw material, only a stem containing a large amount of cellulose may be used as a raw material, or a stem and leaves or roots may be used as a raw material. If the stevia raw material is bleached by oxygen bleaching without using chlorine, there is no problem of environmental pollution during incineration and disposal.

As described above, it is needless to say that as the papermaking pulp, only the stevia pulp may be used, or a mixture of ordinary woody pulp obtained from wood or recycled pulp may be used. As such wood, it is also possible to use wood such as udo which also contains a large amount of cellulose.

(Example 4) The stevia fiber according to the present invention is a fiber produced using stevia raw material,
A fourth embodiment will be described with reference to FIG. Also in Example 4, at least one part including the stem among three parts of the leaf, stem and root of stevia is used as a raw material (stevia raw material). Now, a case in which stevia paper is manufactured including all three parts of leaves, stems and roots will be described.
After the stevia leaves, stems and roots are dried, they are finely ground to about 0.1 to 1 mm with a pulverizer (mixer) to produce pulverized stevia.

Next, the pulverized stevia is put into a melting pot, an appropriate amount of water is added thereto, and the mixture is heated to obtain a stevia solution in which the medicinal components of the stevia are eluted. Then, the stevia solution is squeezed by, for example, a squeezing device having a structure in which pressure is applied to a filter attached to one end opening of the cylinder by a piston sliding in the cylinder, and a concentrated solution from which the medicinal component of stevia is extracted. Can be obtained. This concentrated solution is a medicinal ingredient extracted from stevia by further fermentation treatment, etc.,
Used for medicines, health foods, etc.

By the way, the marble of the stevia raw material (marc) remaining after the concentrated liquid is squeezed contains a large amount of cellulose. The stevia fiber according to Example 4 is a fiber obtained by using cellulose contained in the marble of the stevia and mixing it with a known chemical fiber material. Here, the chemical fiber means regenerated fiber such as rayon, semi-synthetic fiber such as acetate, synthetic fiber such as nylon, and inorganic fiber such as glass fiber. The production of the stevia fiber will be further described.

The marble of the stevia raw material is taken out of the drawing device, mixed with the chemical fiber material (raw material), and sufficiently stirred so as to be uniformly mixed. Then, when the stevia marc is mixed, a mixture of chemical fiber raw materials is spun to produce fibers (stevia fibers).

Example 5 Next, Example 5 will be described as a stevia fiber of the present invention. In Example 5, as in Example 3, the concentrated liquid was not squeezed out of stevia,
Dispose in large quantities, especially stems and roots, dry after collection, pulverize, or shred and pulverize with a roller after pulverization to produce pulverized stevia, which is directly mixed with chemical fibers and spun. It is a manufactured stevia fiber.

Thus, as in the case of stevia paper,
Cellulose contained in a large amount of stevia or stevia marc is effectively used as a fiber material, and woven from a cloth woven from stevia fiber or a mixed fiber obtained by mixing stevia fiber with silk or cotton. The strength of the fiber or the cloth is strengthened and improved because the fiber cloth of the stevia is mixed in the cloth.

Furthermore, the antibacterial component and medicinal component of stevia or stevia remaining in stevia marc remaining in the marble act to obtain a fiber product with enhanced antibacterial properties.
Extremely healthy and comfortable clothes, etc., rich in antibacterial properties can be obtained. In recent years, many people have various allergic symptoms due to various causes. In the present invention, stevia has a histamine detoxifying effect, which exerts an allergy suppressing effect.

Thus, woven fabrics made from stevia fibers or mixed fibers of stevia fibers and other fibers are suitable for women's sanitary products, diapers for infants and the elderly, masks, medical sheets, pillow covers, bandages, Gauze, white coat, pajamas, underwear, socks, towels, slippers, etc., can be used for a variety of textile products including medical and hygiene products and daily use, and is especially suitable for textile products that directly touch the skin. Stevia fiber exhibits its antibacterial and allergic function,
Sanitary and healthy fiber products can be provided.

Also, woven fabrics made of stevia fibers or stevia fibers and other fibers are used for rugs such as curtains, carpets and carpets, partitions, upholstered chairs, sash screens, architectural cloth upholstery materials, tablecloths and other construction materials. It can also be used as interior and interior materials. It exerts its antibacterial and allergy improving functions and can provide a sanitary and healthy living environment.

Although the embodiments of the present invention have been described based on the embodiments, the present invention is not limited to such embodiments, and various implementations are possible within the scope of the claims. Needless to say, there are examples.

[0043]

As described above, according to the present invention,
Conventionally, a large amount of stevia (especially stems and roots) or marbles of stevia, which had been generated in large quantities and had no utility value, were used as paper products and textile products, and were used as interior finishing materials for construction and other medical applications. In addition, Stevia can be effectively used for various applications such as paper products and textile products, and the medicinal components of Stevia, such as antibacterial and detoxifying effects, can be exhibited, so that Stevia can be used synergistically and completely.

Conventionally, the extracted component of stevia was used only for a part of food and medicine, etc., but in the present invention, it is effectively used for clothes and dwelling, and through the improvement of the living environment and textile products,
In addition to improving the health of humans on a daily basis, it is possible to solve the problem of the disposal of a large amount of stevia or stevia marc and the impact on the global environment.
