The purpose of this study is to analyze the functional effects of Dried Distiller's Grains with Solubles (DDGS) as an ethanol-based byproduct in order to find the applicability of DDGS as a cosmetic material and to improve its value. In the anti-oxidation test, based on DPPH and ABTS radical scavenging assay, anti-oxidation activity was found, and ABTS radical scavenging activity was improved. Given that, anti-oxidation effects seemed to be attributable to hydrophilic substances, rather than hydrophobic substances. According to the whitening effect analysis through Tyrosinase inhibition assay, a 25% inhibition activity was found using a concentration of 10㎎/ ㎖. In the collagenase inhibition activity test, for the analysis on the wrinkle-care effect, a 70% inhibition activity was found using a 6㎎/㎖ concentration; in the elastase inhibition activity test, a 96% inhibition activity was found using the 100㎎/㎖ concentration. The water extract from the DDGS sample did not have better whitening or wrinkle-care effects than the positive control group arbutin and EGCG (epigallocatehin gallate). However, when it was compared with brown rice and barley, its anti-oxidation, whitening, and wrinkle-care effects did not fall much. It indicates that DDGS, mainly used as animal feed, is applicable as a cosmetic material.

本研究为了提高酒精生产附属物酒精粕的价值，并了解作为化妆品材料所具有的功能，对其抗氧化活性、美 白效果、抗皱效果等进行了分析。用玄米和大麦以5比1的比例混合制成的晾干酒精粕，在80℃温度进行4小时 回流提取，并对提取物进行浓缩和冷冻干燥后，用作试料。通过DPPH和ABTS清除自由基活性实验，在抗 氧化实验中确认了抗氧化活性，并呈现ABTS清除自由基活性更加优秀，由此可见抗氧化活性源于亲水性物 质，而非疏水性物质。通过Tyrosinase阻碍活性分析结果显示，美白效果在10㎎/㎖浓度中的阻碍活性为2 5%。为确认抗皱效果分别进行了collagenase阻碍活性试验和ellastase阻碍活性试验。两个实验中，阻碍活性 在不同浓度中呈现的百分比各不相同，前项试验中6㎎/㎖浓度的阻碍活性为70%，而后项试验中100㎎/㎖浓 度的阻碍活性为96%。通过比较两性对照群熊果素和EGCG(epigallocatehin gallate)发现，玄米和大麦混合 的酒精粕提取物的美白效果和抗皱效果并不高，但相比酒精工艺之间的玄米和大麦的抗氧化、美白以及抗皱 效果，其效果并没有显著下降，因此作为化妆品原料，酒精粕尤其利用空间。
