Description

Highly dispersible iron powder composition and its manufacturing method {composite of iron content and their manufacturing method}

Figure 1-Process diagram showing the manufacturing process of highly dispersible iron powder composition according to the present invention.

The present invention relates to a highly dispersible iron powder composition and a method for manufacturing the same, and more particularly, to a high-dispersion iron powder composition having excellent dispersion stability, which is effectively used to strengthen iron powder in preparation for infant formula and other infant formulas, and the preparation thereof. It is about a method.

Recently, the average life expectancy of humans has been prolonged with the advent of an aging society due to the development of medicine, but patients suffering from abnormal metabolism due to an iron deficiency cause diseases such as anemia. Therefore, there is a need for the development of preparations that have the effect of preventing, alleviating and treating geriatric diseases such as anemia caused by aging and metabolic disorders. It is also pointed out that the lack of iron intake is remarkable in children and the elderly during the growing season.

In particular, as the number of double-earned couples has increased, more infant foods, such as powdered milk, have been developed, and iron-enriched foods have been developed and sold.

However, heme iron has an inherent odor, and has a dark brown color. Therefore, heme iron cannot be used in large quantities because it cannot be added to a certain amount by changing the properties and properties of the product when added to food.

On the other hand, iron powders that are insoluble in water do not release ions and thus do not cause binding to proteins. Therefore, it is possible to add a large amount without problems to the stability of proteins. In this case, since it precipitates in a short time, it has a disadvantage that it cannot be used in a large amount because the addition amount is limited by adversely affecting the aesthetics of the food and the characteristics of the product by precipitation.

Attempts have been made to safely suspend insoluble minerals, examples of which include treating calcium carbonate with hydrophilic emulsifiers (Japanese Patent Publication No. 2-31942), slightly soluble with oxyacids. A method comprising stirring a calcium salt to prepare a calcium salt having an average particle size of 1 μm and then adding a hydrophilic emulsifier to the resulting compound (Japanese Patent Application Laid-Open No. 8-107772), calcium carbonate and emulsion with a high pressure homogenizer.

Method for improving the dispersibility of calcium carbonate (Japanese Patent Laid-Open No. 64-69513), and Japanese dispersion method using sucrose fatty acid ester as an additive in calcium carbonate slurry as an additive, Japanese Patent Laid-Open Japanese Unexamined Patent Publication No. 6-127909 discloses a method for preparing calcium phosphate dispersion by wet grinding a mixture of sucrose stearic acid ester having 16 HLB and calcium phosphate under specific conditions. A mixture of stearic acid esters and calcium carbonates is prepared in the same manner, Korean Patent Publication No. 0123539 discloses a sucrose fatty acid ester or calcium carbonate mixture having an HLB of 10, and Korean Patent Publication No. 10-0262379 discloses calcium carbonate, calcium phosphate and pyrophosphate agents.
