Animal-derived food freshness detection method

The invention relates to the technical field of food detection, and discloses an animal-derived food freshness detection method which comprises the following steps: S1, preparing functional glue containing Prussian blue silver; and S2, placing the functional glue and the to-be-detected food in the same closed space, standing, and observing the color presented by the functional glue to confirm the freshness of the to-be-detected food, wherein the chemical formula of the Prussian blue silver is MaAg (4-a) [Fe (CN) 6] 3, M is K or Na, and a is more than 0 and less than 4. The detection method has high sensitivity and can rapidly and accurately detect whether the animal-derived food is fresh or not. 本发明涉及食品检测技术领域，公开了一种动物源食品新鲜度的检测方法，包括如下步骤：S1、制备含有普鲁士蓝银的功能胶；S2、将所述功能胶和待检测食品置于同一密闭空间内，静置后观察所述功能胶呈现的颜色确认所述待检测食品的新鲜度；其中，所述普鲁士蓝银的化学式为MaAg(4-a)[Fe(CN)6]3，M为K或Na，0
