Description

  The present invention relates to a health food comprising sweet potato stems / leaves, kale, and pullulan, and a method for producing the same.

  Sugarcane stems and leaves have not been used effectively yet, but an elegant summer has recently been developed as a varieties for petiole. In addition, the National Institute for Agricultural Sciences, Kyushu Okinawa Agricultural Research Center, Developed a variety "Suiou" that uses rice. It is said that the nutritional components of this "Suio" leaf are not inferior to spinach.

  Vitamin C content 31mg / 100g of "Suio" is more than 19mg / 100g of spinach, and calcium is contained about twice as much as spinach. In particular, polyphenols are known to have a variety of in vivo activities such as antioxidant activity, with a significantly higher content of spinach 1.8 g / 100 g lyophilized powder than 4.9 g / 100 g lyophilized powder. (See Non-Patent Document 1).

  “Suoi” was registered as a seedling in 2004, has a strong growth of stems and leaves, has excellent regeneration of sprouting after cutting, and not only the petiole but also the taste of the leaves.

Kale is said to increase liver function, lower blood cholesterol, improve hypertension, return blood sugar levels to normal, and have intestinal regulation.
Kale is widely used as a health food, for example, a constipation-improving food containing a processed kale (see Patent Document 1), a processed kale, a pine bark extract, brown sugar, and water-soluble dietary fiber. Foods (see Patent Document 2), health foods (see Patent Document 3) characterized by containing kale powder and indigestible dextrin, foods containing kale and aloe (see Patent Document 4), kale processing Food and kale processed food (see patent document 5), antihypertensive food containing kale processed product (see patent document 6), antihypertensive food containing kale processed product (see patent document 7), anticholesterol food containing kale processed product Although many applications have been filed (see Patent Document 8), health foods containing kale, sweet potato stems and leaves are not known.

  Kale, which contains various minerals and vitamins, is widely used as a health food, but has the disadvantage that it has a unique smell and has a disadvantage in taste. On the other hand, the stems and leaves of sweet potatoes, especially “Suiou” stems and leaves, have a good taste and are rich in vitamins and minerals comparable to various vegetables, and are characterized by a high content of polyphenols. By mixing kale and sweet potato, especially "Suiou" stems and leaves, it improves the smell and taste of kale, synergistically reinforces the effects of vitamins, minerals, etc., and has excellent palatability and nutritional value. It is an object of the present invention to provide a high health food.

For example, calcium contains about twice as much kale as “Suoi”, but “Suoi” has about one third of oxalic acid that inhibits calcium absorption. In addition, kale does not have a high iron content, but "Suio" has a higher iron content than spinach. Vitamin C is more contained in kale than "Suio", and the nutritional value is further increased by mixing both.
Table 1 shows the prototype values of "Suio" stem / leaf dry powder and kale dry powder mixed in equal amounts, and the analytical values of "Suio", kale, spinach and cabbage.

  Table 2 shows the polyphenol content values of the prototypes, “Suiou”, spinach, broccoli, and cabbage.

(1) The health food of the present invention is characterized by containing sweet potato stem / leaf powder, kale powder and pullulan. Sweet potato stalk / leaf powder polyphenols, vitamins and minerals, and kale powder vitamins and minerals complement each other to synergistically increase nutritional value and eliminate the unique smell and taste of kale to enhance palatability I did it.
The purpose of pullulan is to improve the working efficiency when it is formed as a tablet, and further to balance the insoluble dietary fiber by increasing the water-soluble dietary fiber content, thereby adjusting the gastrointestinal condition.

(2) The health food according to item (1), wherein the second aspect of the present invention comprises sweet potato stalk / leaf powder 40-60 parts by mass, kale powder 40-60 parts by mass, and pullulan 1-3 parts. It is.
If the sweet potato stalk / leaf powder is 40 parts by mass or less, there is a possibility that the effect of extinguishing the smell and taste peculiar to kale may not be fully exerted. This is because there is a possibility that supplementation of vitamin C that prevents the oxidation of the acid becomes insufficient.
This is because pullulan must be blended in an amount of 1 part by mass or more for tableting, and even if 3 parts by mass or more is added, work efficiency cannot be expected.

(3) The third aspect of the present invention is the health food according to (1) or (2) above, wherein the sweet potato variety is “Suoiou”. Among the sweet potato varieties, "Suio" has strong stem and leaf growth, excellent regeneration of germination after cutting, and not only the petioles but also the taste of the leaves. Also rich in vitamins and minerals.
In open-air cultivation, it can be planted from mid-April and harvest stems and leaves 3-4 times. In institutional cultivation, seeds of early spring can be prepared and stems and leaves can be harvested 5-6 times. The yield of pods decreases as the number of cuttings increases, but it is said that seed pods can be secured if they are cut three times.

(4) The fourth aspect of the present invention is to pulverize the dried sweet potato stalk / leaf powder and the dried kale powder to 30-50 mesh respectively, then mix them together, and further add pullulan to form a tablet. This is a method for producing a health food.
The sweet potato stalks / leaves and kale are each preferably dried to a moisture content of 10% or less, preferably 5% or less. This is because the grinding can be performed efficiently.
Also, grinding is a prospect eye powder in the 30-50 mesh. This is in order to maintain fluidity when tableting and to make the weight of one tablet tablet uniform.

According to the present invention, it is possible to obtain a health food that is rich in polyphenols and vitamins and minerals and that has excellent palatability.
Polyphenols are said to have antioxidant ability, active oxygen (radical) scavenging ability, anti-inflammatory action, anti-HIV activity, melanin production inhibitory action, liver damage reducing action, and antihypertensive action.
Furthermore, the addition of pullulan facilitates the formation of a tablet that is convenient for taking, improves the balance between the water-soluble dietary fiber of pullulan and the insoluble dietary fiber of sweet potato stalk / leaves and kale, and promotes the effect of adjusting the gastrointestinal tract.

The flowchart of the manufacturing process of the health food of this invention was shown in FIG.
After harvesting the sweet potato stalks and leaves and kale stalks and leaves, respectively, wash them with water and drain them, then treat them as they are, or cut them into appropriate lengths.

  It is desirable to perform drying at a relatively low temperature. Dry at around 45 ° C. When freeze-dried, it was considered inappropriate because it became a fine powder when pulverized and became difficult to tablet.

  Sterilization is performed at around 105 ° C. for several minutes.

  Milling is the prospect eye powder in the 30-50 mesh. In order to maintain fluidity when tableting and to achieve uniformity in the weight of one tablet that was tableted, the particle size was adjusted to a medium grain powder.

  The standard composition is 49 parts by weight of sweet potato stalk / leaf powder, 49 parts by weight of kale, and 2 parts by weight of pullulan. However, the composition may be changed as appropriate within the scope of the claims.

  Tableting was performed by a tableting machine, and the standard was a tablet (tablet) weight of 250 mg, a circle with a diameter of 8 mm and a thickness of 5 mm. However, the size is not particularly limited.

  The sweet potato stalks and leaves used in the present invention are not particularly limited to the variety of sweet potatoes, but it is preferable to use the stems and leaves of "Suiou" which is a specific variety. "Suiou" has a high polyphenol content and is characterized by the ability to regenerate stems and leaves even after harvesting the stems and leaves, and also contains abundant polyphenols in the regenerated stems and leaves. There is a feature. Other sweet potato varieties such as Koganesengan, Shiroyutaka, Satsumachichi and Ayamurasaki can also be used.

  Kale can be used for both stems and leaves, but kitchen kale, mallow kale, bush kale, tree kale, Portuguese kale, etc. are used.

The sweet potato stalks / leaves and kale are preferably processed immediately after harvesting. However, when time is required until the processing, it is desirable to store them at a low temperature in order to prevent deterioration.
Drying is performed at a low temperature, preferably around 45 ° C. Drying is performed so that the water content is 10% or less, preferably 5% or less.
After drying, sterilize by heating at around 105 ° C for several minutes.

The pulverization is carried out by a method commonly used by those skilled in the art, for example, using a crusher, a mill, a blender, a stone mortar, etc., and is made 30 to 50 mesh. If the particle size is larger than 30 mesh, it is difficult to uniformly mix with other materials, and if it is smaller than 50 mesh, the tablet processing efficiency may be reduced.
The reason for making tablets is to make it easy to drink anywhere and anytime, and to make it convenient to carry. This is because it is troublesome to take the powder in water each time.

  Pullulan blended for tableting is a polysaccharide made by culturing black yeast using starch as a raw material. It is approved by the Ministry of Health, Labor and Welfare as an additive with no restrictions on its use as a food, pharmaceutical or cosmetic product.

  Table 3 shows a comparison between a prototype made up of 49 parts by weight of "Suiou", 49 parts by weight of kale and 2 parts by weight of pullulan, and a case of alone and in the form of kale alone compared to taste and smell. As for the dosage, 6 tablets of a prototype 250 mg were taken in 2 divided doses 3 times a day, and changes after 30 days were investigated. As for “Suoi” and Kale, the dry powder was taken in the same mass as the tablet and divided into three times a day for comparison.

It is a flowchart of the manufacturing process of the health food of this invention.
