Definitions

  • the present invention relates to a crystalline maltitol powder useful as a sweetener, in particular, to a crystalline maltitol powder less prone to consolidation during delivery or storage, and a method for production thereof.
  • Maltitol is one of sugar alcohols and is a useful substance widely used in the fields of foods, drugs, cosmetics, and so on.
  • maltitol powders known at that time were free from crystals and became sticky immediately on exposure to air by absorbing moistures due to their exceedingly strong hygroscopicity. Therefore, they could not serve as commodities that endure delivery or storage.
  • Powder products of sugar alcohols are generally packaged, stored, and delivered in a resin (e.g., polyethylene) inner bag combined with a kraft bag or in a resin inner bag combined with a corrugated cardboard carton.
  • resin e.g., polyethylene
  • crystalline maltitol powders adopt also the former or latter packaging form.
  • consolidation seen in powdery products means in a broad sense that individual powder particles adhere to each other for some reason such as natural phenomena or artificial manipulation and thereby form a cluster.
  • the phenomena include moisture absorption and air drying, and the manipulation includes addition of water, forced drying, compression, and sintering.
  • consolidation refers, in many cases, to a formation of cluster via moistures caused by repetitive moisture absorption and drying, after adherence stage between powder particles by liquid film bridging or the like resulting form adsorption of water molecules thereto.
  • Crystalline maltitol powder products are rated as having low hygroscopicity as compared with other sugar alcohol powder products. Nevertheless, it is known that crystalline maltitol powder products generate consolidation during delivery or storage, as they have hygroscopicity similarly with other sugar alcohol powder products.
  • the consolidation state of the crystalline maltitol powder products seems to be variously influenced by storage conditions and so on of the products.
  • the consolidation level thereof also varies from a low level of consolidation in which a cluster is easily reduced into powders with a light touch of hand and recovers powder flowability to a high level of consolidation in which a cluster is not reduced even by a strong impact.
  • consolidation level refers to consolidation of powder particles, specifically, to the presence or absence of consolidated matter and to the strength of the consolidated matter.
  • Such powders not only exceedingly hinder handling in works such as transfer, package opening, pulverization, and dissolution but arise problems including reducing work efficiency, failure of automated equipment and thus difficult to use in a variety of applications. Therefore, their commercial values are drastically reduced.
  • the method (2) was applied in some cases such as crystalline xylitol powder products.
  • problems including: a desiccating agent might be mixed accidentally into a product in large-scale production; and cost is increased because the method requires adding a hygroscopic material and carefully taking it out in use of the product. Therefore, the adoption of the method is confined to a small number of crystalline xylitol powder products. The method was not adopted for crystalline maltitol powders and is not distributed.
  • the above-mentioned method is intended to prevent a phenomenon specific to sorbitol in which “hair-like crystals chronologically develop in a vertical direction from surfaces of sorbitol powder particles and mutually intertwine”.
  • the phenomenon in which hair-like crystals chronologically develop in a vertical direction from surfaces of powder particles has not been observed for crystalline maltitol powders.

  • An object of the present invention is to provide a crystalline maltitol powder less prone to consolidation, which shows excellent powder flowability during delivery or storage and to provide a method for production thereof.
  • a general method for producing crystalline maltitol typically includes a method wherein a maltitol aqueous solution is crystallized and subjected to a molasses separation step such as centrifugation to obtain a crystal containing approximately 3% by weight of moisture, and this crystal is then adjusted to a moisture content of approximately 0.1% by weight following a drying step at approximately 70° C. and filled into a packaging material.
  • a crystalline maltitol powder product thus produced is often consolidated during storage or delivery.
  • the consolidation is not always caused by the amount of a moisture in a crystalline maltitol powder and is largely influenced by a difference in moisture content between the surface of a crystalline maltitol powder and the inside of the powder, and by the state of the powder surface.
  • the present inventors have conducted diligent studies on the physical and chemical properties and consolidation phenomenon of a crystalline maltitol powder.
  • the present inventors instead of reducing a moisture content in powder particles as conventionally, the present inventors treated the powder with various methods such as a method involving taking into consideration a balance between a moisture content in the inside of powder particles and a moisture content in the surface of the powder particles or a balance between a moisture content in the inside or surface of powder particles and a moisture content in an atmosphere and a method involving stabilizing the surface of the powder, after a production method generally performed, as described in the above, or during the drying stage of the general production method.
