化学変化は次の通りである。[Detailed Description of the Invention] The present invention relates to a method for producing vitamin D2 in algae, and in particular, applies ultraviolet rays of 280 to 320 nm to seaweed, seaweed, seaweed, arame, rockweed, ogonori, kawanori, konbu, kelp, etc. The aim is to irradiate algae such as hijiki, wakame, and mozuku to efficiently and economically convert ergosterol present in the algae into vitamin D2. The chemical changes that occur when ergosterol is irradiated with ultraviolet light and vitamin D2 is produced are as follows.

上重要なビタミンD2を多量に生成することに成
功した。 By the way, it is known from Japanese Patent Publication No. 51-26493 that ergosterol exists in shiitake mushrooms and that vitamin D2 is produced by ultraviolet rays.
The present inventors confirmed that ergosterol exists in algae, and by irradiating it with specific ultraviolet light (wavelength 280 to 320 nm), the present inventors can efficiently produce ergosterol without adding chemicals or reacting. Moreover, they succeeded in producing large amounts of vitamin D2, which is important for health, without losing vitamin A present in algae.

Vitamin D2 is produced by the ultraviolet rays of
It was also confirmed that the amount was small and that it took a long time.

少なくなつている。現実に４訂日本食品標準成分
表によると、藻類中のビタミンD2の含有量は零
になつている。 In recent years, in order to economically obtain clean, homogeneous edible seaweed, processing operations have been carried out indoors.
The content of vitamin D2 in the raw material, algae, is becoming even lower. In fact, according to the 4th edition of the Japanese Food Standard Composition Table, the content of vitamin D2 in algae is zero.
280〜320nｍの紫外線では照射による発熱はな

適当な水分の藻類に照射し乾燥すれば表面に光択
を生じる。また、照射は藻類を薄葉にし、水分は
80％以下が好もしい。水分が多いと紫外線が藻類
表面の水に吸収されるからである。 Ultraviolet rays of 280 to 320 nm do not generate heat due to irradiation, and the wavelength is longer than the wavelength that causes erythema, so there is generally no change in the appearance of the algae surface.
If algae with appropriate moisture are irradiated and dried, photoselectivity will occur on the surface. Irradiation also makes algae into thin leaves and water is removed.
80% or less is preferable. This is because when there is a lot of moisture, ultraviolet rays are absorbed by the water on the surface of the algae.

た。 Next, I will give three examples to show the effect: (1) 15g of Amanori with 70% water content moving in the dryer
If you line up a thin leaf of 20cm x 20cm with Toshiba's health line lamp (20W) and irradiate it for 10 minutes from a distance of 30cm, the vitamin D2 of Amanori will be 320IU (100g).
dry weight) to 2430IU. Moisture 1.2
Amanori that has been dried to 50% is more photosensitive than one that has been dried without irradiation, and it contains vitamin A before and after drying.
There was no change at 13,000 IU (100 g dry weight).

た。(3) Also, 10g of Iwanori with 50% water content was made into a thin leaf of 18cm x 18cm, and the two health line lamps (20W) mentioned above were installed at a distance of 35cm from the surface, and after 20 minutes of irradiation, vitamin D2 was 2220IU. Noiwanori (100
g dry weight) was obtained. Foods left outdoors for 6 hours on a sunny day on the San'in Coast in January will contain vitamin D2.
The amount of vitamin A was 570 IU (100 g dry weight) and 12000 IU (100 g dry weight).
しかも之等紫外線を照射したものは光択、色
調は共に満足すべきものであつた。 Moreover, the brightness and color tone of these materials irradiated with ultraviolet light were satisfactory.

Incidentally, FIG. 2 shows the relationship between the distance from the light source and the irradiance for one health lamp [20W].
この結果から放射照度と照射時間の積は0.3
〜12000μw・min/cm2が適当である。 From this result, the product of irradiance and irradiation time is 0.3
~12000 μw・min/cm 2 is appropriate.

提供し得るものである。 Judging from the above examples, if you use a commercially available health line lamp to irradiate properly dried algae as thin leaves, the ergosterol contained in the algae will not be lost and the vitamin A contained in the algae will not be lost. can be easily activated to form vitamin D2, which has become an effective means of quality improvement, especially for operations carried out indoors for the processing of algae for clean and homogeneous food, especially in recent years. It can be easily understood from the above examples that it is suitable as a useful processing method that is not affected by the weather in terms of production.In particular, algae contains calcium, potassium, sodium, phosphorus, iron, etc. High inorganic content (4th edition Japanese Food Standard Composition Table)
It has been revealed that vitamin D2 is effective for health, and in particular, the presence of vitamin D2 is extremely effective in the nutritional cycle of calcium, and can provide a valuable health food.
