PROBLEM TO BE SOLVED: To provide a method for easily and economically producing a novel food of a double-layer structure, which can stably maintain a double-layer constitution and optionally provide various tastes and textures with high designability.SOLUTION: A food of a double-layer structure contains a coating component that contains saccharides as an essential main ingredient and contains polysaccharides comprising at least uronic acid, and an internal ingredient that contains saccharides as an essential main ingredient and contains at least multivalent cations or an internal ingredient 3A that contains saccharides as an essential main ingredient and contains polysaccharides comprising at least uronic acid, and a coating ingredient 2A that contains saccharides as an essential main ingredient and contains at least multivalent cations, wherein the multivalent cations move to the ingredient 3A side that contains polysaccharides comprising uronic acid, to cause the crosslinking reaction of both to thereby produce a gel-like reaction product 6.COPYRIGHT: (C)2013,JPO&INPIT【課題】安定して2層構成を維持することができ、意匠性が高く、多様な食味・食感を任意に提供できる新規な2層構造食品および容易に経済的に製造できる製法の提供。【解決手段】糖質を必須主成分として含み、少なくともウロン酸で構成される多糖類を含む被覆成分と、糖質を必須主成分として含み、少なくとも多価陽イオンを含む内部成分とからなるか、あるいは、糖質を必須主成分として含み、少なくともウロン酸で構成される多糖類を含む内部成分3Aと、糖質を必須主成分として含み、少なくとも多価陽イオンを含む被覆成分2Aとからなり、前記多価陽イオンが前記ウロン酸で構成される多糖類を含む成分3A側に移動して両者が架橋反応してゲル状反応生成物6となることを特徴とする2層構造食品により課題を解決できる。【選択図】図1
