Definitions

  • the present invention relates to a method for producing gelatin having improved solubility in water or an aqueous solution.
  • direct dissolving method When gelatin powder is directly introduced into water or an aqueous solution and dissolved without going through a swelling operation (hereinafter, such a dissolving method is referred to as “direct dissolving method”), gelatin particles are rapidly and uniformly dissolved in water. Dissolves only when wet and dispersed. The dissolution time of gelatin in direct dissolution depends on the particle size of the gelatin powder, and the finer powder should dissolve in a shorter time. However, gelatin powder, as it becomes finer, is less likely to be uniformly wetted in water as it is and forms mako. Therefore, the time required for the dissolving operation (from powder input to complete dissolution) is rather coarse. Are often short. In addition, if it is fine powder, the dust is also high. Spray granulation is one of the methods to improve the handling of these small powders and improve the solubility.
  • Spray granulation is a method in which saccharides, salts, surfactants, and the like are sprayed on gelatin as a binder to form granules.
  • this method uses a large amount of excipients such as sugars and salts, so that the use of the obtained gelatin with improved solubility is very limited. There is a problem that it cannot be adopted in the field where things are used.
  • As a method of obtaining 100% gelatin with improved solubility of gelatin there is a method of granulating gelatin powder by spray granulation using water as a binder.
  • this method when the fine powder is granulated, the original gelatin Although the solubility is improved, the problem still remains if it is still maco.
  • the time required for dissolution is increased and it is not improved.
  • an object of the present invention is to provide a method for producing a solubility-improved gelatin which can increase the dissolution efficiency of gelatin and shorten the time required for dissolution.
  • gelatin particles When gelatin is introduced into water or an aqueous solution, gelatin particles begin to swell upon dissolution. In general, the dissolution rate of gelatin particles is almost the same as the swelling rate, so that the gelatin particles that first come into contact with water swell and envelop other gelatin particles. This is probably one of the reasons why gelatin powder becomes mako. And, as the gelatin particles become finer, that is, as the powder becomes finer, mako is formed. On the other hand, among the gelatins, the water-soluble gelatin has higher solubility than other gelatins, and has the property of not swelling. Therefore, the present inventors consider that if the swelling start time of gelatin particles can be delayed by utilizing the properties of the water-soluble gelatin, the wettability and dispersibility can be improved, and the above object can be achieved. The present invention has been completed.
  • the gist of the present invention is to provide a method for producing a solubility-improved gelatin that improves the wettability and dispersibility of gelatin by coating water-soluble gelatin on the surface of gelatin particles.
  • water-soluble gelatin refers to a gelatin having a low molecular weight obtained by hydrolyzing gelatin or a raw material thereof with an acid, alkaline, proteolytic enzyme, or the like. It dissolves quickly without swelling even in water at room temperature (at 25), and has good properties if it has no gelling ability. Viscosity measurement according to JIS 6503 indicates a viscosity of 20 mP or less. From the point of practical use, those with a viscosity of 15 mP or less are preferred. Shuu.
  • the solubility of gelatin in water or aqueous solutions depends on whether the gelatin is simply soluble in them, not whether it is better or worse, but whether the gelatin is wet or dispersible. It depends heavily.
  • the solubility improvement refers to improving the solubility efficiency by improving the wettability and dispersibility of gelatin particles, and shortening the time required for the entire dissolution operation (ie, the above-mentioned solubility). You can do it.
  • the temperature of water or aqueous solution is not particularly limited.
  • the gelatin particles used in the present invention are not particularly limited.
  • the type of gelatin is not particularly limited, and it is possible to use gelatin-treated gelatin or gelatin-treated gelatin, and various types can be used.
  • the method of coating the surface of the gelatin particles with the water-soluble gelatin is not particularly limited.
  • a method such as spraying a water-soluble gelatin solution on gelatin powder that has been kept in a fluidized state may be used. Puru. If the water-soluble gelatin powder is sprayed with water-soluble gelatin and then coated, the granulation is performed at the same time. Solubility becomes better. In addition, since granules are formed into granules, generation of dust can be suppressed.
  • the method of keeping the gelatin powder in a fluid state is, for example, often by air blowing, but is not limited to air blowing, such as using a stirring blade or using a combination of air blowing and a stirring blade.
  • the gelatin particles coated with water-soluble gelatin on the surface dissolve without swelling the water-soluble gelatin on the surface when poured into water or an aqueous solution, so that the particles of the gelatin powder are uniformly accelerated. Crab gets wet. As a result, the occurrence of mako is suppressed, and the dissolution of gelatin particles starts without delay. For this reason, according to the production method of the present invention, even if gelatin is used as a powder, the wettability and dispersibility are improved, and if granulation is performed at the same time, the dispersibility will be improved accordingly. The solubility of the layer is improved.
  • the solubility-improved gelatin obtained by the production method of the present invention has a water content of 6.8.
  • the temperature * humidity conditions for coating the water-soluble gelatin should be adjusted as appropriate. After the gelatinization, the solubility-improved gelatin is subjected to an appropriate temperature and humidity condition, for example, but not limited to these methods. ⁇ The solubility-improved gelatin according to the present invention is not limited to these methods. In the method of preparing gelatin, the water-soluble gelatin is coated on the surface of the gelatin particles to improve the wettability and dispersibility of the gelatin.
  • gelatin having improved solubility can be obtained.
  • the improved dispersion and dispersibility of gelatin With the improved dispersion and dispersibility of gelatin, the occurrence of mako during dissolution in water or an aqueous solution is prevented, and the dissolving workability is improved. Since water-soluble gelatin is derived from gelatin, the solubility-improved gelatin obtained can be used for various purposes without using anything other than gelatin.

  • the properties of the particles were not significantly different except that the sugar-based coating agent (Sample 8) was harder and more sticky than the others. Was.
  • water-soluble gelatin Since water-soluble gelatin has no gelling ability and has a lower viscosity than gelatin, it can be obtained by using a large amount as a coating agent and bringing in a large amount of gelatin powder.
  • the viscosity of the solubility-improved gelatin is expected to affect the jelly strength. This is the same problem with sugar as a coating agent (sample 8). However, no significant effect was observed in the range of coating agent concentration (5 to 20%) shown in Table 1 (Part 1) and (Part 2).
  • Sprayed water (sample?) Has a high bulk and is light, and the dispersibility is not improved but deteriorates. Mamako is also born.

From this point, the solubility of gelatin (samples 1 to 3) coated and granulated using water-soluble gelatin shows much better results than the other gelatins. As in the case of dispersibility, coated products having a water-soluble gelatin concentration of 10 to 20% are excellent in terms of solubility.
