Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a method for producing a polyglycerol fatty acid ester powder composition, and more particularly to a method for producing a polyglycerol fatty acid ester powder composition that is easily dissolved or dispersed in cold water. [Prior art and its problems] Since polyglycerin fatty acid esters were approved as food additives, they have been recognized for their versatility, that is, for esters with a wide range of physical properties from high HLB to low HLB products, and for their thermal stability. High, acid resistant,
Excellent salt resistance and hydrolysis resistance, O/
Excellent W-type emulsion stability, tasteless,
Because it is odorless, it has come to be widely used in a wide range of foods, cosmetics, medicines, etc. However, its shape is usually solid, flake, liquid, paste, etc. Regardless of the shape, when it is dissolved in water and used, its solubility is low, and it is difficult to dissolve and disperse it during use. It was inefficient as it required a separate measure. Another problem is that it is extremely difficult to directly add this type of polyglycerol fatty acid ester to powder products. [Problems to be solved by the present invention] The problems to be solved by the present invention are to solve the above-mentioned difficulties of conventional polyglycerin fatty acid esters, and more specifically, to improve solubility and dispersibility even in cold water. The purpose of the present invention is to develop a polyglycerol fatty acid ester powder composition that has excellent properties and can be directly added to powder products. [Means for solving the problem] This problem can be solved by dissolving or dispersing polyglycerol fatty acid ester and a specific starch hydrolyzate called DE3-30 in cold or hot water, and then spray-drying the solution. achieved. That is, the present invention relates to a method for producing a polyglycerol fatty acid ester powder composition, which comprises dissolving or dispersing a polyglycerol fatty acid ester and a starch decomposition product of DE3 to 30 in water or hot water, and then spray-drying the composition. . [Structure and operation of the invention] As the polyglycerin fatty acid ester used in the present invention, any conventionally known ester can be used. For example, a part or all of the hydroxyl groups of polyglycerin can be replaced with stearic acid or oleic acid. , those produced by direct esterification with fatty acids such as lauric acid, and those produced by transesterification with fats and oils can be similarly used. As the fatty acids and fats and oils in this case, any conventionally used fatty acids can be used, and fatty acids usually having 8 or more carbon atoms are preferred, including the above-mentioned fatty acids.
Typical examples include cottonseed oil, palm oil, cow oil, soybean oil, and hydrogenated palm oil. The form of this polyglycerin fatty acid ester is not limited in any way, and various conventionally known forms, such as solid, flake, liquid, and paste forms, can be widely used. The starch decomposition product used in the powderization of the present invention may be one obtained by hydrolyzing starch with acid or enzyme, as long as it has a DE in the range of 3 to 30. A combination of these can also be used. DE is outside the above DE range, i.e. DE is 3
If this is not achieved, the solubility and dispersibility in cold water, which is a feature of the present invention, will be poor and the effect will not be fully exhibited. Moreover, when DE is greater than 30, the starch decomposition product easily absorbs moisture and lacks long-term storage stability, which is unsuitable. As the starch decomposition product used at this time, any product can be used as long as its DE is within the above prescribed range, such as potato starch,
Specific examples include corn starch and various other starches decomposed into predetermined values. In the present invention, the ratio of these two to be used is preferably polyglycerol fatty acid ester.
Starch decomposition product is 30 parts by weight or more per 100 parts by weight,
Particularly preferably 80 to 250 parts by weight. At this time 30
If the amount is less than 1 part by weight, the powdering properties during spray drying will be poor and the fluidity will also be reduced, making it impossible to obtain a powder of good quality. When carrying out the method of the present invention, polyglycerin fatty acid ester and starch decomposition product are dissolved or decomposed in cold or hot water. Polyglycerol fatty acid ester has a solid, flaky, liquid, paste, etc. shape and has low solubility, and in order to dissolve or disperse it in the aqueous phase in carrying out the present invention, the temperature of the aqueous phase must be adjusted to a preferable value. teeth
It is preferable to raise the temperature to 60°C or higher. Furthermore, even in hot water, it is preferable to stir to promote dispersion, and particularly preferably to forcefully disperse using an emulsifying machine. However, the polyglycerin fatty acid ester and the starch decomposition product may be dissolved in any order, but it is preferable to first dissolve or disperse the polyglycerin fatty acid ester, which has a slightly poor dissolution and dispersion, and then add the starch decomposition product, which is easily soluble. In the method of the present invention, this is then spray-dried. Spray drying is essential for drying at this time, as other drying methods are difficult to achieve the desired purpose.
For example, drum drying tends to cause scorching, freeze drying is expensive, and other methods may have the disadvantage that it is very difficult to obtain powder. The method of spray drying itself is not particularly limited, and any of various conventional spray drying methods may be used. The polyglycerol fatty acid ester powder composition thus obtained has excellent solubility and dispersibility in hot water as well as cold water, and can be directly added to powder products. [Example] Experimental examples and examples will be shown below to clarify the characteristics of the method of the present invention. <Experimental example> Decaglycerin monostearate (trade name MSW- manufactured by Sakamoto Pharmaceutical Co., Ltd.) was used as a sample.
750, paste) was dispersed in 70°C warm water, DE2.2,
Starch decomposition products of 4.4, 7.3, 15.4, 29.7, and 32.6 (trade name: Pinedex, manufactured by Matsutani Chemical Industry Co., Ltd.) were added, dissolved, emulsified, and then heated in a spray dryer with hot air temperature of 160°C and exhaust air temperature of 100°C. Spray-dried at. The conditions and results are summarized in Table 1. The storage stability of the obtained powder was determined by storing the powder in a desiccator at a relative humidity of 81% for 24 hours and observing changes in the state. Example Using polyglycerol fatty acid ester manufactured by Sakamoto Pharmaceutical Co., Ltd. and starch decomposition products of various DEs in the Pinedex series manufactured by Matsutani Chemical Industry Co., Ltd., the experiments shown in Table 2 were carried out in the same manner as the above experimental method. The following four types of powdering were carried out. The results are shown in the same table.
