る。TECHNICAL FIELD The present invention relates to iron reinforced prunes. For more details,
The present invention relates to a food which is effective in replenishing iron content of iron deficient people by eliminating bitterness, fishy taste and metallic taste caused by a hemoglobin-derived compound containing heme iron by adding prune.

していないのが現実である。(Prior Art) It is said that about half of Japanese women are currently iron deficient. It is said that about 500 million people in the world population have iron deficiency, and various measures have been taken against iron deficiency in Europe and America. In the United States, by adding 4 mg of iron to 100 g of flour, bread 1
Iron is fortified at a rate of 17.5 to 27.5 mg per kg. In Sweden, 6.5 mg of iron is added to 100 g of flour. However, the reality is that iron fortified foods are not popular in Japan.

心、おう吐、腹痛、下痢などの症状を呈する。Regarding iron fortification of foods, non-heme iron such as iron lactate, iron citrate, and ferrous sulfate is known. However, it is well known that such non-heme iron is poorly absorbed into the body and is inhibited by phytic acid, dietary fiber, calcium and tea tannin in grains or processed grain foods. Furthermore, when these compounds are ingested in large amounts, they exhibit symptoms such as nausea, vomiting, abdominal pain and diarrhea.

ある。On the other hand, heme iron, which is abundant in meat and liver, is better absorbed than non-heme iron, and is not affected by other ingredients in food, according to E. Bjorn-Rasmusssen et al. The Journal of Cl.
inical Investigation Volume 53 (1974) pp. 247-255,
It is a well-known fact as described in A. Turubull et al., Vol. 41 (1962), pages 1897-1907. However, the hemoglobin-derived compound containing heme iron has a bitterness, fishy taste, peculiar to heme iron,
Since it has a metallic taste, the problem is that it causes discomfort when ingested.

There is a technique of adding heme iron to chocolate as described in Japanese Patent Publication No. 59-140835. However, chocolate has a strong taste and is not something that many people can eat in large quantities every day, and other foods are also desired. Many women, especially those with a high iron deficiency, tend to keep their diet in mind and tend to avoid eating chocolate with high sugar and fat contents.
また、チョコレートは嗜好食品であり、毎日摂取するよ
うな食品ではないため、日常食事として摂取するものか
ら鉄分を補給できるようにする必要がある。Further, since chocolate is a favorite food and is not a food that is ingested every day, it is necessary to be able to supplement iron from what is ingested as a daily meal.

The fishy taste and metallic taste can be eliminated. If the amount of prune is less than 19 parts by weight per 1 part by weight of the hemoglobin-derived compound containing heme iron, the effect of eliminating the bitterness, fishy taste, and metallic taste due to the hemoglobin-derived compound containing heme iron is reduced. However, the effect becomes remarkable when the amount is 19 parts by weight or more.
