PROBLEM TO BE SOLVED: To provide a method for producing a seaweed food including making seaweed powder produced by cutting or crushing food material of seaweeds such as dried laver, into a capsulated one to be stored for a long period of time without addition of salt, and having a shape suitable as cooking raw material and excellent in good appearance, and to provide the seaweed food produced by the method.SOLUTION: The seaweed food is produced by preparing a seaweed-dispersed substance composed of seaweed powder, acid, water-soluble polysaccharide salt solution, and dropping the seaweed-dispersed substance to a calcium salt solution to form a polysaccharide water-insoluble calcium salt coat on the surface of the dropped substance to make a spherical seaweed food. Such seaweed food is suppressed in increase in various germs and the like even when the seaweed is in moist condition due to antibacterial effect and sterilization effect owing to acid so as to be long stored. The seaweed food is usable as materials for various kinds of food as well as being eaten as it is because the acidic taste is compatible with other seasonings, and thus has a wide range of utilization compared to the one preserved by salt or the like.COPYRIGHT: (C)2010,JPO&INPIT【課題】海苔等の海藻類などの食材を裁断又は粉砕してなる海藻粉末をカプセル状とし、食塩を加えることなく長期保存をすることができ、更に料理の素材に適した美観に優れる形状を備える海藻食品の製造方法及びこれにより製造される海藻食品を提供することを課題とする。【解決手段】本海藻食品は、海藻粉末と酸と水溶性多糖類塩溶液からなる海藻分散物を調製し、その後、海藻分散物をカルシウム塩溶液に滴下して滴下物の表面に多糖類の難水溶性カルシウム塩被膜を形成させた球状の海藻食品とする。このような海藻食品によれば、酸による制菌及び殺菌効果により、海藻が湿潤した状態でも雑菌等の増加を抑制することができるため長期保存が可能である。また、酸味は他の調味料との相性もよく、塩による保存などに比べて食材としての応用範囲が広くなり、本海藻食品をそのまま食用にできるのみならず各種食品の材料に用いることができる。【選択図】なし
