PROBLEM TO BE SOLVED: To provide a manufacturing method of an edible metallic foil in which a conventional foil beating method is improved to increase the safety of human organism and also to efficiently manufacture the edible metallic foil, the edible metallic foil manufactured by using the manufacturing method and a cosmetic including the edible metallic foil.SOLUTION: A manufacturing method of an edible metallic foil comprises: a first rolling process in which metal is rolled by using edible rolling oil by a first rolling mill a second rolling process in which the metal is rolled by using edible rolling oil by a second rolling mill instead of a Koppe process where the metal is beaten out by use of a Zumiuchi machine after the first rolling process and an Ara-gane process in which the metal is beaten by the Zumiuchi machine. Generally, rolling work by use of the rolling mill can keep a constant quality without depending on long time experience or intuition of an operator. The edible rolling oil is left as coating on front and rear surfaces of the metallic foil that is the finished product, so that harmful effect to human organism is completely eliminated.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】 伝統的な箔打ち方法に改良を施すことで人体への安全性を高め且つ効率的に製造できる食用金属箔の製造方法、当該方法を使用して製造した食用金属箔及び当該食用金属箔を含有する化粧料を提供する。【解決手段】 本発明の食用金属箔の製造方法は、金属を可食性の圧延油を用いて第1のロール圧延機で圧延する第1の延金工程を行った後、当該金属を澄打機で打ち延ばす小兵工程の替わりに、可食性の圧延油を用いて第2のロール圧延機で更に圧延する第2の延金工程を行い、次に当該金属を澄打機で叩く荒金工程を経て金属箔を得ることを特徴とする。一般的にロール圧延機を用いる圧延作業は作業者の長年の経験や勘に頼らなくても一定の品質を保つことができる利点がある。また、可食性の圧延油は完成品の金属箔の表裏両面に皮膜として残るため人体に及ぼす悪影響をほぼ完全に無くすことができる。【選択図】図2
