JPH11346716A - Food containing zinc in organic state - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a food capable of being commercialized, readily taken by improving taste and utility and making its effect more effective, having treating and preventing effects on osteoporosis, fracture, etc. SOLUTION: Zinc in an organic state is used as a zinc-containing material so as to improve taste. When a zinc additive to be added is in an organic state, the additive is not chelated even if a food contains a component such a phytic acid, etc. The utility of the food can be raised. Especially, in the case where the food contains isoflavone, the synergistic effect with zinc can be expected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a zinc-added food which can be used for the treatment and prevention of osteoporosis and fractures and has an action of accelerating bone formation and preventing a decrease in the amount of bone mineral. .

[0002]

2. Description of the Related Art Osteoporosis occurs frequently in postmenopausal women, the cause of which is a decrease in estrogen. Many elderly people become bedridden due to lumbar compression fractures and femoral neck fractures caused by osteoporosis. Since the treatment requires a long period of time, it not only greatly affects patients and their families, but also leads to an increase in medical expenses. Therefore, prevention of osteoporosis by proper diet is desired.

[0003] Many researchers have reported that calcium is important for bone formation, and that there is a close correlation between the incidence of osteoporosis and dietary calcium intake. Although the number of osteoporosis patients in Japan is not small, it has been reported that the incidence of calcium is lower in Japanese people than in Western countries, despite the fact that they have lower calcium intake. Many dietary components may be involved in this, but recent epidemiological studies have reported that isoflavones contained in soybean foods are affecting them. That is, since isoflavones have a female hormone-like action, it is said that they promote bone formation in bone tissue and suppress bone resorption.

[0004] Zinc is an essential element for humans. Although the required zinc intake has not yet been set in Japan, the required zinc intake in the United States is 15
mg / day (Recommended dietary allowances, 10
(1989) National academic press, Washington DC). As a result of a dietary survey, the intake of zinc by Japanese people is estimated to be about 9 mg / day, which is not considered to satisfy the required amount. The biochemical function of zinc is stabilization of large molecules, its structural role on metalloproteins, and its functional role also affects enzyme activities related to protein synthesis (Trace elements in human and animal nutrition,
2, pp1-137 (1986) Academic press, Orland, FL).

[0005] The source of zinc for Japanese is mainly seaweed, dried fish and other seafood. Although zinc sulphate is used for zinc deficient patients, it is designated as an extraterrestrial substance and is not allowed to be added to foods for the purpose of fortifying zinc. Even if permitted, metal elements generally have a distinctive metallic odor, making it difficult to fortify into foods in terms of taste. On the other hand, under the current situation where it is clear that the intake of zinc is insufficient, sunflower oligotaine (Japan Shoji), sesame mineral (Japan Biochemical Research Institute), aquamineral (Japan Biocon), etc. have been launched as products to enhance zinc. I have. When they are used as food additives, they have no problem in taste, but they do not have much zinc content.

It has been proposed that the addition of zinc to this isoflavone enhances the effect of isoflavone on promoting bone formation and preventing bone mineral loss by synergistic effect (see Japanese Patent Application Laid-Open No. Hei 10-114653). Specifically, a zinc salt is added to a soybean product as an isoflavone-containing food, but as described above, addition to a food is not permitted, and it is impossible to commercialize the product as it is. Also.
Soy products are high in phytic acid. This phytic acid is known to chelate zinc and greatly reduces zinc availability (JG Reinhold et al.,
J. Nutr., 105 (1974)). For this reason, when a zinc salt is added to a soybean product, much of zinc is chelated by phytic acid, and the usability is greatly reduced. further,
The taste problem of the metal element as described above also arises.

[0007]

SUMMARY OF THE INVENTION The present invention can be commercialized without violating laws and regulations, and can be easily taken by improving taste and utilization, thereby making the effect more effective. The aim is to obtain foods that have a therapeutic and preventive effect on bones and fractures.

[0008]

Means for Solving the Problems The zinc-added food of the present invention is characterized in that an organic zinc-added food is used as the added zinc material in order to improve the taste. The present inventors,
When organic zinc is used as the added zinc material, the intake amount is 100g without violating the laws on additives
It has been found that even when zinc is contained in an amount of 5 mg or more, no problem occurs in taste.

[0009]

DETAILED DESCRIPTION OF THE INVENTION When the zinc additive to be added is organic, it is chelated even if the food contains a component which produces a chelating compound of zinc such as phytic acid. No, it can improve usability. When the food is an isoflavone-containing food, a synergistic effect with zinc can be expected. The present inventors have reported that salty organic salts (Solutia (trade name, manufactured by Benfact Corporation)) and zinc yeast (Oriental Yeast, Glow Company (USA), Cell Life (USA), BioSpringer (US) French) are preferred. In addition, the zinc yeast could be substituted for other than the above. Further, by adding a plurality of these organic zinc additives in combination, it has become possible to strengthen zinc without impairing the taste. This was expected to make it easier to consume foods having a therapeutic and preventive effect on osteoporosis and bone fractures.

[0010]

EXPERIMENTAL EXAMPLES The present invention will be described in more detail with reference to experimental examples. (Test Method) A sensory evaluation test was performed using tea having a soybean hypocotyl portion as a main component containing a large amount of soy isoflavone. First, 9 g of a tea bag containing hypocotyls was placed in 800 ml of boiling water and simmered for 10 minutes over low heat. After cooling, the saltia and the zinc yeast have a zinc content of 2-7 mg / 100.
ml. The influence on the taste was evaluated by a sensory evaluation test of zinc-added tea, with no addition as a control. In other words, 10 panelists drink these teas with the sample down face down, 3 points if there is no difference between the control and 2 points if there is no change. A score of 1 was given if there was no problem with the taste, and a score of 0 was given if it was judged unpleasant and had no commercial value. The results were shown as the average value of 10 panelists.

(Effect on taste by addition of zinc material) FIG. 1 shows the effect of saltia and zinc yeast on taste, FIG. 2 shows the effect on odor, and FIG. 3 shows their comprehensive evaluation. Show. The horizontal axis is the amount of zinc in 100 ml of tea,
The vertical axis is the average value of the evaluation points. As shown in the results, the effect on taste was observed even when the added amount of the material was 2 mg / 100 ml, and the evaluation became lower in proportion to the added amount. The addition of 5 mg / 100 ml dropped below one point.

(Improvement of Taste by Combination of Zinc Materials) Next, a test was conducted by combining these materials.
The test was performed in the same manner as in the case of single addition, and the sensory evaluation was performed by mixing Saltia and zinc yeast at a ratio of 1: 1. The results are shown in the table below. The numbers in the table indicate the number of people who gave 0 points.

[Table 1] As a result, the concentration at which half the people gave 0 points was 3 mg / 100 ml for Saltia and 5 mg / 100 m for zinc yeast.
l, but by mixing these, 7 mg /
An increase in the threshold value of 100 ml, which was uncomfortable, was observed.

[0013] As a result, the food can be eaten delicious even if zinc is fortified, and a food that can contribute to human health by preventing osteoporosis can be provided. In particular, the combination of isoflavone and zinc has improved the taste of foods that can be used for treatment and prevention of osteoporosis and fractures, and has made it possible to add zinc without impairing the commercial value.
