The present invention relates to a method for producing vitamin A or artificial rice fortified mainly with vitamin A. In recent years, with the increasing trend of using cooked rice as a staple food in school lunches, the method of ingesting vitamin A, which is necessary for children's growth and development, has become important. In other words, it is easy to fortify vitamin A in bread, which has traditionally been the mainstay of school lunches, but it is not possible to fortify boiled rice with vitamin A, depending on the well-known manufacturing technology for vitamin B 1 and B 2 enriched rice. It was considered difficult. This is because vitamin A is fat-soluble. As a result of studying the vitamin A fortification of rice, the present inventor found that vitamin A fortified artificial rice can be advantageously produced by using an artificial rice manufacturing technology that applies extrusion molding under high pressure, and that this can be advantageously produced in rice. The present invention was based on the knowledge that vitamin A can be ingested with cooked rice by adding and mixing an appropriate amount during cooking. That is, the present invention provides vitamin A or vitamin A
The purpose is to provide a method for producing artificial rice fortified with vitamins, mainly . The present invention will be explained in detail below. In the present invention, the raw material of artificial rice is used in powder form, and for example, joshinko is used alone or is used as a main ingredient, and sweet potato starch, potato starch, and other starches are blended with this. In addition, in order to increase the specific gravity of the artificial rice obtained, a smaller amount of second rice is added.
Preferably, it contains calcium phosphate. An example of the composition of raw materials for the artificial rice used in the present invention is shown in Table 1 below.

例示する。[Table] A desired amount of vitamin A or a vitamin mixture mainly composed of vitamin A is added and mixed in the form of an aqueous suspension to the above-mentioned raw material mixture for artificial rice. That is, since vitamin A is not water soluble, it is used in suspended form. Note that it is preferable to use vitamin A to which vitamin E is added as an antioxidant. The amount of the aqueous suspension added to the artificial rice raw material may be such that the artificial rice raw material is moistened. By extruding the artificial rice raw material under high pressure through this humidification, the starch in the raw material is gelatinized by frictional heat and formed into rice grains. The above extrusion molding method under high pressure has been used in recent years to gelatinize starch components, and for example, a commercially available puff machine molding machine (manufactured by Kawaguchi Iron Works) can be applied. This puff machine molding machine, as disclosed in Japanese Utility Model Publication No. 55-48672, consists of a raw material introduction and discharge pipe, a cylinder housing a screw, a plate-shaped nozzle with multiple through holes, a rotating cutter, and a blower fan. The humidified raw material is introduced into the screw from the discharge pipe, and the starch in the raw material is gelatinized by frictional heat, extruded from the nozzle in a viscoelastic state, cut into rice grains by the rotating cutter, and then passed through the blower fan. and then dried to form artificial rice. Through this extrusion molding under high pressure, fortified artificial rice fortified with vitamin A or vitamins mainly consisting of vitamin A is obtained, which is then dried to form a product. Vitamin A in fortified artificial rice obtained by the present invention
Although the content is lost by about 20 to 30% during production, the residual amount is high, so by appropriately adding it when cooking rice, it is possible to ingest an effective amount of vitamin A along with the cooked rice. Furthermore, the residual rate of vitamin B1 added together with vitamin A in artificial rice is 80% to 90%, and the loss rate is extremely low, so it is possible to fully ingest the effective amount. According to the present invention, when fortified artificial rice was produced using vitamins A and B1 , the results of measuring the residual ratio of the vitamins to the added amounts are shown in Table 2 below.

When rice is cooked by adding the strengthened artificial rice obtained by the present invention, the artificial rice tends to float to the top of the cooked rice because the specific gravity of the artificial rice is smaller than that of rice. Since it is thoroughly stirred (so-called loosening operation), there is almost no problem in practice. However, the specific gravity of the above artificial rice is such that a small amount of secondary
It can be increased by adding calcium phosphate. The results of investigating the effect of addition of dibasic calcium phosphate on the specific gravity of artificial rice are shown below. Fortified artificial rice is produced according to the present invention by adding and mixing the same amount of an aqueous suspension of vitamin A to each raw material having the blending ratios No. 1 to No. 4 shown in Table 1 above. The true specific gravity of each artificial rice was measured before and after cooking. The results are shown in Table-3.

ビタミンB1 1.41mg／ｇ 90[Table] As seen in the above table, when dibasic calcium phosphate is added to the raw material at an amount of about 7% by weight, the true specific gravity increases. The amount of the fortified artificial rice according to the present invention added to the rice during cooking is usually about 1/200. By the way, if artificial rice raw materials are simply moistened and molded using conventional methods, when added to rice and mixed, it has a low specific gravity and is easy to separate from the rice, and the starch in the raw materials is not pregelatinized, so it cannot be cooked. There is a tendency for rice to disintegrate or float to the surface and be lost during regular washing (washing), but such drawbacks are not observed in the present invention. As described above, the present invention can advantageously provide vitamin A or fortified artificial rice mainly containing vitamin A, which is suitable for addition to boiled rice, and therefore supplements vitamin A in school lunches where boiled rice is the staple food It is highly beneficial. The present invention will be specifically described below by way of examples. Example 1 Joshin flour 15Kg Sweet potato starch 3Kg Potato starch 2Kg Artificial rice raw material combination consisting of the above composition (total 20
kg), vitamin A (300,000 IU/g) 248 g, vitamin E (purity 20%) 1.25 g, vitamin B 1 hydrochloride
A vitamin mixture consisting of 31.2 g and 0.2 g of vitamin B 2 (total amount 280.65 g) is added and mixed. Water 7 is added to the raw material mixture to which the vitamin mixture has been added and mixed as described above, and the mixture is thoroughly moistened. The raw material mixture is shaped into rice grains by supplying it, melting it under high pressure, and extruding it. The resulting rice granules are then dried to obtain vitamin-enriched artificial rice with a moisture content of 11.6%. The content of each vitamin in the obtained fortified artificial rice is as follows. Residual rate (%) Vitamin A 1710IU/g 70 Vitamin B 1 1.31mg/g 84 Example 2 Joshin flour 12.75Kg Sweet potato starch 3Kg Potato starch 1.25Kg Dibasic calcium phosphate 3.00Kg Artificial rice raw material combination consisting of the above composition ( Total amount
A vitamin mixture having the same composition as described in Example 1 was added and mixed to 20 kg), and this mixture was subjected to the same procedure as described in Example 1 to obtain fortified artificial rice. The moisture content of the obtained fortified artificial rice was 14.4%, and the results of measuring the various vitamin contents are as follows. Residual rate (%) Vitamin A 1890IU/g 76 Vitamin B 1 1.41mg/g 90
