Description

[Technical Field]

[0001] The present invention relates to an oral liquid composition containing an iron compound, and is useful for the treatment of various diseases such as medicines, quasi-drugs, and foods. It can be used in the fields of [Background technology]

[0002] Although iron is an essential metal for the body, the intake of iron is low compared to the recommended intake, especially in women. It has been reported that people tend to be deficient in this nutrient. The recommended amount of iron for women is 10.5 mg. The iron intake of the elderly is 7.5 mg, which means that they are deficient in iron by about 3 mg per day (Non-Patent Document 1) As an efficient way to ingest iron through diet, drinks and supplements containing iron compounds are available. However, iron compounds react with other ingredients, impairing flavor and quality. (Patent Documents 1 and 2).

[0003] In recent years, drinks and supplements containing collagen peptides and elastin peptides have also become popular. Collagen is the main component of the dermis, ligaments, tendons, bones, cartilage, etc. Collagen peptides are proteins obtained from animals and fish. Elastin is found in the ligamentum nuchale, aorta, skin, and lungs. It is the main protein of fibers that is widely distributed in various tissues that require elasticity, such as Reference 3).

[0004] Elastin peptides are produced by hydrolyzing raw materials such as animal aortas and fish bulbs of arteries. In this way, collagen peptides and elastin peptides are obtained from pig and fish. Because it is obtained from protein, it has a distinctive unpleasant odor.

[0005] So far, we have developed a beverage with a good flavor that contains collagen hydrolysate, such as Job's tears extract. , safflower extract, apricot extract, and carrot extract. extract, royal jelly, one or more selected from vitamin B2 and vitamin B6 Contains two or more vitamins, dietary fiber, sugar, stevia, plum juice, and sodium L-aspartate. A beverage containing a blend of citric acid, an acidulant, and a fruit flavor has been reported (Patent Document 3 ). [Prior art documents] [Non-patent literature]
