Description

  The present invention relates to an easily soluble solid beverage having a porous structure. Specifically, the present invention relates to a molded easily soluble solid beverage that can be easily dissolved or uniformly dispersed by adding to water or hot water.

  Conventionally, various powder-type instant beverages that are immediately dissolved and dispersed in addition to water and hot water have been studied. However, if it is a powder type, the powder may scatter when it is scooped with a spoon, or the amount of one cup may be difficult to understand. Moreover, even if it is individually packaged for each cup, powder may be spilled when poured into a cup. Therefore, the solid beverage is not in the form of powder as described above, but in a solid shape such as candy, for example, the amount of each cup becomes one solid, the amount of each cup is easy to understand, and water or hot water There is a need for solid beverages that dissolve or disperse quickly.

  On the other hand, solid beverages that are expanded using a foaming agent or the like to have a porous structure have been studied. For example, (1) a water-soluble or water-dispersible active ingredient of a tasteful beverage such as coffee or green tea, (2) a foaming agent for food, and (3) a mixture of at least one sweetener sugar and water. A method for producing a readily soluble solid beverage having a porous structure, characterized by drying a foamed aqueous composition containing boiled rice cake and (4) water under reduced pressure (Patent Literature) 1) etc. However, in order to prepare the cocoon-like material, a complicated process such as a step of boiling at a high temperature of 100 ° C. or higher and a step of drying under reduced pressure are required, and although it has a porous structure, it is molded. However, there were still problems such as scattering properties of the obtained solid beverage.
