Chestnuts are widely cultivated for their edible portion (kernel), whereas the non-edible parts are discarded. To enable the utilization of the by-products of processed chestnuts, we separated them into green and brown burs, shells, inner skin, and leaves, and analyzed the bioactive properties of the ground components. We also created a composite paper, comprising the inner skin, and examined its deodorant properties. It was revealed that the inner skin had the highest functionality and showed potent antioxidant, antibacterial, and deodorant properties. Furthermore, when we produced a paper, containing 60% inner skin, and examined its deodorant properties, we found that it was highly effective in deodorizing ammonia and acetic acid gases. These results show that the inner skin of chestnuts is a promising material for developing hygiene and other products.
栗子因其可食用部分（果仁）而被广泛种植，而非食用部分则被丢弃。为了能够利用加工栗子的副产品，我们将它们分离为绿色和棕色的刺苞、外壳、内皮和叶子，并分析了磨碎成分的生物活性特性。我们还制作了一种包含内皮的复合纸，并检测了其除臭性能。结果表明，内皮具有最高的功能性，并表现出强大的抗氧化、抗菌和除臭性能。此外，当我们制作一种含有60%内皮的纸并检测其除臭性能时，我们发现它对氨气和醋酸气体具有高效的除臭效果。这些结果表明，栗子内皮是开发卫生和其他产品的一种有前景的材料。
