Problems solved by technology

However, there is a problem that when soybean protein is present in a high concentration in the powder raw material, even if it is made into granules, the settling property in water deteriorates, making it difficult to improve the solubility in water
However, none of these methods has achieved a sufficient improvement in the water solubility of soybean protein.

Embodiment

[0122]Hereinafter, although an Example and a comparative example demonstrate this invention further, this invention is not limited to the following example.

[0123] 〔test methods〕

[0124] The measurement method used in this example will be described below.

[0125] [Average particle size, uniformity U, content ratio of coarse powder and fine powder]

[0126] Using the laser diffraction / scattering type particle size distribution analyzer Mastersizer 3000 (manufactured by Malvern Co.) and the accompanying software Mastersizer 3000, the volume-based particle size distribution plotted by plotting the particle diameter on the horizontal axis and the abundance ratio of particles on the vertical axis was obtained. . As the measurement conditions, the hopper gap is 3.5 mm, the feeder strength is 20-40%, and the air pressure for powder conveying is 0.2 bar.

[0127] From the obtained volume-based particle size distribution, the average particle size (median size), the content rati...

manufacture example 1

[0131] Soybean protein-containing composition 1 before granulation was prepared by mixing the following components.

[0132] Refined soybean protein (trade name HD101R, manufactured by FUJI OIL CO.,LTD.)

[0133] Maltodextrin

[0134] cocoa powder

[0135] salt

[0136] sweetener

[0137] Vitamin Blend (contains vitamins A, B1, B2, B6, B12, C, D, E, K, pantothenic acid, folic acid, niacin)

[0138] The prepared above-mentioned composition 1 was introduced into a fluidized bed machine together with an emulsifier (polyglyceryl fatty acid ester) as a liquid component (binder) and an aqueous solution of thickening polysaccharides (pullulan and gum arabic). In the granulator, granules having the composition shown in Table 1 were obtained. In addition, eight types of granulated materials A to H shown in Table 2 were obtained by changing the binder addition amount, spray air flow rate, etc.

[0139] The particle size of the composition 1 before granulation was 80 to 100 μm, and...

manufacture example 2

[0151] In Production Example 2, the average particle diameter was substantially the same, and the difference in residue weight based on the uniformity U was confirmed.

[0152] The above-mentioned composition 1 prepared in Production Example 1 was introduced into a fluidized bed granulator together with an emulsifier as a liquid component (binder) and a thickened polysaccharide aqueous solution. Air flow rate etc., thereby can obtain 4 kinds of granules (I~L) shown in Table 3.

[0153] Moreover, similarly to manufacture example 1, the evaluation of water solubility was performed about the obtained granulated material I-L.

[0154] The results are shown in the following Table 3 and image 3 .

[0155] [table 3]

[0156] Table 3 Manufacturing Example 2

[0157]

[0158] From Table 3 and image 3 As a result, it was found that among the granules with an average particle diameter in the range of 150 to 220 μm, the granules I and J with a uniformity U of 0.58 or less had a ...

Abstract

One embodiment of the present invention relates to a protein granulated material containing soy protein as a main component, the protein granulated material having an average particle diameter of 150-220 [mu] m, a uniformity U of 0.58 or less, and a content ratio (volume ratio) of coarse powder having a particle diameter of 300 [mu] m or more of 27% or less, and the content ratio (volume ratio) of fine powder having a particle diameter of 100 [mu] m or less is 30% or less.

Description

technical field [0001] The present invention relates to protein granules, particularly protein granules containing soybean protein as a main component. Background technique [0002] Soybean protein can be obtained by degreasing soybeans, for example, extracting with an alkaline solution, and passing through an acidic precipitation process. [0003] Soybean protein is used as a protein supplement source such as sports nutrition food and diet food. However, when the soybean protein is dissolved in water as it is, the surface of the powder block becomes glutinous, forming lumps and lumps. Once agglomerated, it is difficult to dissolve unless the agglomerates are crushed finely. [0004] Generally, in order to improve the water solubility of a powder raw material, there is known a method of making granules by granulation to improve settling properties so that they can be easily dispersed or dissolved in water. However, there is a problem that when soybean protein is present i...
