Description

  The present invention relates to a method for granulating powder. More specifically, the present invention relates to a method for granulating a powder such as a water-soluble polymer, and relates to a method for granulating a powder in which a powder such as a water-soluble polymer is easily dissolved without causing ramping (dama) when dissolved in water.

  It is known that when a water-soluble polymer such as xanthan gum or guar gum is dissolved in water or liquid food as powder, so-called ramping occurs and the powder becomes very difficult to dissolve in liquid. Lamping is formed when powder is added to an aqueous solution and only the surface of the aggregate of powder is hydrated and dissolved, and moisture does not migrate to the interior of the aggregate. , Is called dama etc. When such ramping occurs, it does not readily dissolve in water, and in order to completely dissolve it, it is necessary to increase the stirring strength or lengthen the time.

  On the other hand, it has been conventionally practiced to produce granules in which powder raw materials are bonded and integrated with a binder component (binder). Generally, a fluidized bed granulator is used as a means for producing a granulated product in a dry state. Yes. The granulation mechanism by fluidized bed granulation is to keep the granular material that is the base material in the fluidized bed in a fluid state, spray the binder liquid into the fluidized bed, agglomerate the powders with the binder, and dry. It is granulated (Non-Patent Document 1).

  As the binder liquid used at the time of granulation, water is used, or a method of using an aqueous solution containing a water-soluble dispersant such as dextrin (Patent Document 1), the pH of the granule raw material to be granulated with the binder liquid Is adjusted to acidic (about pH 2 to 4) to produce a granulated product (Patent Document 2). However, the effect of suppressing ramping (dama) when the granulated powder after granulation is dissolved in water is insufficient, and further improvement is expected. Further, in the method of treating xanthan gum with a surfactant (Patent Document 3), the solution causes turbidity due to the surfactant, and it is difficult to use it for food with high transparency.

  The present invention has been developed in view of such circumstances, and an object of the present invention is to provide a powder granulation method for easily dissolving powder, particularly water-soluble polymer powder, without causing ramping in water.

  As a result of intensive studies to solve the above problems, the present inventors have used this powder granulated product by using an aqueous solution containing ascorbic acids as a binder, particularly when granulating a water-soluble polymer. It was found that when dissolved in water, it can be easily dissolved without causing ramping in water. Furthermore, the present granulation method was confirmed to be particularly effective when fluidized bed granulation was performed, and the present invention was completed.

The present invention relates to a method for granulating a powder having the following aspects;
Item 1. A method for granulating a powder, wherein an aqueous solution containing ascorbic acids is used as a binder.
Item 2. Item 2. The powder granulation method according to Item 1, wherein the powder is a water-soluble polymer.
Item 3. Item 3. The powder granulation method according to Item 1 or 2, wherein the granulation method is fluidized bed granulation.
Item 4. Item 4. An easily soluble granule composition granulated by the method according to any one of items 1 to 3.

  The granule composition granulated by the granulation method of the present invention can be easily dissolved without causing ramping in water when dissolved in water.

  The powder granulation method according to the present invention is characterized by using an aqueous solution containing ascorbic acids as a binder.

  According to the present invention, a powder, in particular, a water-soluble polymer powder is granulated by the method of the present invention, so that the powder granulated product can be easily dissolved without causing ramping in water. Even in the case of a solution containing saccharides or other additives, ramping of the water-soluble polymer can be prevented in the present invention.

  The ascorbic acid used in the present invention is not particularly limited, and includes, for example, not only ascorbic acid but also rhamno-ascorbic acid, arabo-ascorbic acid, gluco-ascorbic acid, fuco-ascorbic acid, glucohepto-ascorbic acid, xylo -Ascorbic acid, galacto-ascorbic acid, gulo-ascorbic acid, allo-ascorbic acid, erythro-ascorbic acid, those similar to ascorbic acid such as 6-desoxyascorbic acid, etc. It doesn't matter. These may be L-form, D-form, or racemate. Specifically, for example, L-ascorbic acid, L-ascorbic acid palmitic acid ester, L-ascorbic acid stearic acid ester, L-ascorbic acid 2-palmitic acid ester, L-ascorbic acid sodium, L-ascorbic acid calcium, D -Arabo-ascorbic acid etc. can be mentioned. Preferably, sodium L-ascorbate can be used.

  These ascorbic acids are used in a proportion of 1 to 15% by weight, preferably 2 to 8% by weight, based on the powder. This is because if it is less than 1% by weight, ramping when dissolved in water may not be sufficiently suppressed, and if it exceeds 15% by weight, the granulated state may be deteriorated.

  These ascorbic acids are used as a binder in an aqueous solution. The concentration of ascorbic acids in the aqueous solution is 1 to 30% by weight, preferably 5 to 20% by weight. This is because if it is less than 1% by weight, it takes time for granulation, and if it exceeds 30% by weight, the granulated state may be deteriorated. In the present invention, an aqueous solution containing ascorbic acids may be used and is not affected by pH.

  First, the powder to be granulated in the present invention is not particularly limited as long as it is a powdery composition, but is preferably a water-soluble polymer, and more preferably a water-soluble polymer having a property of gelling and / or thickening. Suitable for the granulation of powder. Specific examples of powders of water-soluble polymers having gelling and / or thickening properties include xanthan gum, galactomannan (guar gum, locust bean gum, tara gum, etc.), carrageenan, cassia gum, glucomannan, native gellan gum. , Deacylated gellan gum, tamarind seed gum, pectin, psyllium seed gum, gelatin, tragacanth gum, karaya gum, gum arabic, gati gum, psyllium seed gum, macrohomopsis gum, agar, alginates (alginate, alginate), curdlan, pullulan , Methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), sodium carboxymethylcellulose (CMC), hydroxypropylcellulose (HPC), hydroxyethylcellulose (HEC) cellulose derivatives such as water-soluble hemicellulose, soybean polysaccharides, processed and modified starch, raw starch (raw starch), can be exemplified one or two or more selected from such dextrin.

  Among these, it is preferable to use one or more water-soluble polymer powders selected from galactomannan and carrageenan such as xanthan gum, guar gum, locust bean gum, and tara gum.

  Although it is the granulation method of this invention, it can manufacture by a conventional method except using the above-mentioned binder liquid. For example, there are fluidized bed granulation, rolling granulation, stirring granulation and the like. In the present invention, it is preferable to produce by a fluidized bed granulation method. The following method can be illustrated as a manufacturing method by fluidized bed granulation. For example, powder is put into a granulator, and hot powder is sent from below to make the powder flow. A method of producing granules by spraying the above-mentioned binder liquid onto the fluidized bed with a nozzle, uniformly adhering the binder liquid to the powder surface, forming aggregated particles, and drying the aggregated particles can be mentioned.

  Furthermore, the present invention relates to a readily soluble granule composition produced by the above-mentioned method, in which ramping of powder, particularly water-soluble polymer powder, is prevented.

  Although the easily soluble granule composition of this invention should just contain the said component at least, as long as there exists an effect of this invention, another arbitrary component can also be mix | blended.
