  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a flowchart showing a method for producing dragon fruit powder according to the present invention.
In this example, the dragon fruit leaves after fruit removal were used. Below, the procedure of the manufacturing method of the dragon fruit mesophyll powder of this invention is demonstrated.

S-1) The leaf part 1 of the dragon fruit after leaf part collection fruit picking is cut out and cut into a suitable length. About 30 cm is preferable (see (1) in FIG. 2).

S-2) Barb removal Sharp spines 2 grow at appropriate intervals at the three apex portions of the triangular radial leaves of the Goragon fruit (see FIG. 2 (1)). The barb 2 is cut out and removed (see FIG. 2 (2)). If it is scraped off with a peeler or the like, it can be easily removed without hurting the hands with the spines 2.

S-3) The surface of the leaf part 1 (see FIG. 2 (2)) from which the surface washing barbs 2 have been removed is washed with water. Because it is pesticide-free, there is no need for cleaning with detergent.

S-4) Cutting treatment Cut along the three concave portions of the triangular radial cross section of the leaf portion 1 after washing with a blade. When all three sides of the dent are cut, the leaf portion 1 is divided into three. (See Figure 3)

S-5) The core part 4 is separated and removed from the cut piece 3 divided by the core part removal cutting process. As shown in FIG. 3, the core 4 has a thin circular bar shape and can be easily separated. When the spine portion and the core portion were removed from the leaf portion of 100 kg, the weight was about 85 kg.

S-6) The sliced core 4 is removed, and the mesophyll pieces separated into the three cut pieces 3 are sliced to about 0.5 to 1.0 mm. Slicing makes it easier to dry the post-treatment. The thinner the slice thickness, the better. Since the thorns are removed in advance, slicing is easy. Slicing is difficult if the spines remain. Slicing is different from crushing and is easy to handle and dry.

S-7) Drying treatment The sliced dragon fruit mesophyll is dried. Dry to about 1-10%. The drying method is not particularly limited, such as warm air drying, vacuum drying, far-infrared drying, sun drying, and the like. 100 kg of raw material was dried to a moisture content of 4% to obtain a dried product of about 8.5 kg.

S-8) Grinding treatment The dried dried mesophyll slices were pulverized to about 0.1 mm to 1.0 mm with a pulverizer.

S-9) Particle size adjustment When the pulverized mesophyll powder was sieved and the particle size was adjusted to 0.2 mm or less, a beautiful light green dragon fruit mesophyll powder (S-10) was obtained.

  FIG. 4 shows a component analysis table of the dragon fruit mesophyll powder thus produced. As can be seen from this table, the content of mineral components such as sodium, potassium, calcium and magnesium is very high.

  FIG. 5 shows an analysis table of the dragon fruit core powder. As is clear from comparison with the components of the mesophyll powder in FIG. 4, the core portion had a mineral component of 1/3 to 1/50 of the mesophyll portion. It is clear that the functional component of the core cannot be expected.

  In addition, the powder of only the mesophyll part does not contain impurities, so the quality is uniform and high safety when mixed with other foods, health foods as dietary supplements, other foods, soaps, Various products such as cosmetics can be manufactured.

  Next, the usage example of the dragon fruit mesophyll powder by this invention is demonstrated.

[Example 1]
Sikhwasa juice and water were mixed at a ratio of 3: 7 to obtain a 200 cc beverage. To this, 2 g of dragon fruit mesophyll powder was added and mixed thoroughly with stirring. This drink was drunk 2-3 times a day after meals and continued for 3 months. Bone density increased from 75% to 95%.

[External application example 1]
Add about 0.5 g of dragon fruit mesophyll powder to about 1 to 2 cc of water or lukewarm water, mix well, and apply to the face after washing. Twice a day in the morning and evening for 3 months, the skin became tense, whitened, and my face was spotted.

[External application example 2]
2 g of dragon fruit mesophyll powder was added to 2 to 3 cc of water, mixed and applied to the skin after tanning after washing the face. The heat of tanning was removed overnight and there were no burn marks.
