BACKGROUND OF THE INVENTION
The present invention relates to a coating agent used for granular orally ingested products, and in particular, to improve dispersibility of liquid orally ingested products such as foods and pharmaceuticals in liquids such as water. It is related with the coating agent which can do.
[0002]
[Prior art]
Various methods have been used to disperse poorly water-soluble powdered orally ingested products in liquids such as water, such as particle refinement, addition of surfactants, chemical modification, and formation of molecular complexes. It was. However, many of these methods still have problems such as high costs and dispersibility not sufficiently improved.
[0003]
As one of the methods conventionally used for the above purpose, there is a method of coating a granular orally ingested product with a coating agent containing a sucrose fatty acid ester. Sucrose fatty acid esters are suitable for use as an additive for orally ingested products such as foods and pharmaceuticals because they are highly safe and have almost no taste or fragrance.
[0004]
However, conventional coating agents using sucrose fatty acid esters still do not have sufficient dispersion performance, and a large amount of addition is required to obtain the desired dispersion performance. Or in order to acquire a desired effect, it was sometimes used together with other emulsifiers or food materials.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above, and is a coating agent (hereinafter simply referred to as a coating agent) for an orally ingested product such as a granular food or medicine using a sucrose fatty acid ester, It is an object of the present invention to provide a coating agent that is remarkably superior in dispersion performance in a liquid such as a conventional coating agent of the same type, and thus can obtain a desired dispersion effect in a smaller amount.
[0006]
[Means for Solving the Problems]
The coating agent of the present invention is a powdery orally ingested product coating agent containing a sucrose fatty acid ester, and in order to solve the above problems, as a sucrose fatty acid ester, a monoester content ratio Is 80% by weight (hereinafter simply referred to as%) or more.
[0007]
The coating agent of this invention obtained by the above is used suitably as a coating agent for foodstuffs or a pharmaceutical.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The sucrose fatty acid ester used in the coating agent of the present invention has a monoester content ratio of 80% or more, and more preferably has a monoester content ratio of 90% or more. By using sucrose fatty acid ester with a monoester content ratio of 80% or more, the dispersion performance of the coating agent is dramatically improved, and it is easy to coat even cold water or highly viscous liquids that are normally difficult to disperse. Can be dispersed. Conventionally, the monoester content ratio of sucrose fatty acid esters that have been used in coating agents such as foods and pharmaceuticals is about 70% at most.
[0009]
The sucrose fatty acid ester preferably has 8 to 22 carbon atoms, more preferably 12 to 22 carbon atoms, and still more preferably 14 to 22 carbon atoms, from the viewpoint of easy availability. Use things.
[0010]
The coating agent of the present invention can be composed of a sucrose fatty acid ester alone satisfying the above conditions, but if necessary, glycerin fatty acid ester, sorbitan fatty acid ester, crystalline cellulose, carboxymethylcellulose, saccharides, etc. It can also be added within a range not departing from the object of the invention.
[0011]
The granular orally ingested product (coating material) to which the coating agent of the present invention is applied is not particularly limited, and is a granular or food and pharmaceutical product that needs to be dispersed in a liquid such as water. It can be used for all orally ingested products. As used herein, “powder and granule” includes both powder and granules (granule), and “orally ingested product” is orally ingested by humans and other animals. It refers to all things. “Food” and “medicine” are not limited to narrow meanings, but include health supplements and quasi drugs. As typical examples, foods include powders such as protein, cocoa and calcium, and pharmaceuticals include poorly water-soluble substances such as phenytoin, estriol, furosemide, ibuprofen and indomethacin.
[0012]
The method of coating these orally ingested products with the coating agent of the present invention is not particularly limited, for example, a method of spraying sucrose fatty acid ester dissolved in a solvent such as alcohol, water, propylene glycol, etc. For example, a method of directly applying the mixture by mixing sucrose fatty acid ester with the material to be coated and stirring. The term “coating” as used herein includes not only the case where the object to be coated is entirely covered with the coating agent but also the case where the coating agent is partially attached to the surface of the object to be coated. .
[0013]
Although the usage-amount of the coating agent of this invention is based also on the kind of to-be-coated material, as a rough standard, it is about 0.01-1 weight part with respect to 100 weight part of to-be-coated material.
[0014]
【Example】
Examples of the present invention will be described below, but the present invention is not limited thereto. In the following, MSE represents the monoester content ratio.
[0015]
[Example 1]
By spraying 5 g of sucrose fatty acid ester (18 carbon atoms, MSE: 95%) dissolved in ethanol (concentration 1%) in 100 g of protein powder with a sprayer, and then drying at room temperature for 12 hours, the present invention A protein powder coated with the above coating agent was obtained.
[0016]
[Example 2]
100 g of cocoa powder was mixed with 0.5 g of sucrose fatty acid ester (carbon number 18, MSE: 95%) and stirred to obtain cocoa powder coated with the coating agent of the present invention.
[0017]
[Example 3]
100 g of cocoa powder was mixed with 0.5 g of sucrose fatty acid ester (18 carbon atoms, MSE: 90%) and stirred to obtain cocoa powder coated with the coating agent of the present invention.
[0018]
[Example 4]
100 g of cocoa powder was mixed with 0.5 g of sucrose fatty acid ester (carbon number 18, MSE: 80%) and stirred to obtain cocoa powder coated with the coating agent of the present invention.
[0019]
[Example 5]
100 g of cocoa powder was mixed with 0.5 g of sucrose fatty acid ester (16 carbon atoms, MSE: 90%) and stirred to obtain cocoa powder coated with the coating agent of the present invention.
[0020]
[Example 6]
Coating was carried out by spraying 100 g of ibuprofen with a sucrose fatty acid ester (carbon number 18, MSE: 95%) dissolved in ethanol (concentration: 1%) with a sprayer, followed by drying at room temperature for 12 hours.
[0021]
[Comparative Example 1]
A coated protein powder was obtained in the same manner as in Example 1 except that sucrose fatty acid ester (18 carbon atoms, MSE: 70%) was used as a coating agent.
[0022]

[0023]
The dispersibility of each sample obtained in the above examples and comparative examples was evaluated by the following criteria by putting the sample into water and visually observing the state of the suspended matter. The results are shown in Table 1.
[0024]
◎: Familiarize quickly with little floating matter ○: Familiarize quickly with water, but there is some floating matter △: Familiarity with water is slightly slower, there is a little floating matter ×: Familiarity with water is slow, floating There are many things [0025]

【The invention's effect】
According to the coating agent of the present invention, the dispersibility of poorly water-soluble powdered orally ingested products in liquids such as water can be dramatically improved and easily dispersed in cold water or highly viscous liquids. Will be able to. Therefore, the effect is exhibited with a smaller amount of use than in the past, and it is not necessary to use other emulsifiers and food materials together with the conventional amount, so that the desired effect can be obtained with less cost.
