PROBLEM TO BE SOLVED: To provide a production method of fermented matured placenta solution capable of increasing absorptivity or a useful component of the placenta solution.SOLUTION: In a production method of fermented matured placenta solution, which is a production method of fermented matured placenta solution for fermenting and maturing placenta by adding yeast having fermentation action into a placenta solution of a pig, a sheep or a horse, muscovado as much as 6-15% to the placenta solution in terms of the weight ratio is added into the placenta solution to thereby generate fermentation, followed by maturation after the fermentation.SELECTED DRAWING: Figure 1【課題】プラセンタ溶液の吸収性や有用成分を増加させる発酵熟成プラセンタ溶液の製造方法を提供すること。【解決手段】本発明の発酵熟成プラセンタ溶液の製造方法は、豚、羊または馬のプラセンタ溶液に、発酵作用を有する酵母菌を加えてプラセンタを発酵および熟成させる発酵熟成プラセンタ溶液の製造方法であって、プラセンタ溶液に対して重量比で6~15%の黒糖をプラセンタ溶液に添加して発酵させ、発酵後に熟成させたことを特徴とする。【選択図】 図1
