The chemical composition and the antioxidant properties of Capsicum annum discarded seeds from processing industry with their corresponding extracted oil were investigated. C. annum seeds had high levels of crude proteins (18.30%), crude oil (11.04%), and dietary fibers (60.96%). The lipophilic fraction of C. annum seeds showed higher radical scavenging activity compared to their hydrophilic fraction, while this latter exhibited the highest reducing power. The results of fatty acid composition showed that fatty acids present in C. annum seed oil were mainly polyunsaturated (84.23%), with linoleic acid being the major polyunsaturated fatty acid (70.93%). The major monounsaturated fatty acid was oleic acid (12.18%), while the main saturated fatty acid was palmitic acid (11.90%). C. annum seed oil showed high absorbance in the UV-B, UV-A, and visible ranges. Owing to their composition, C. annum seeds discarded from pepper processing industry as by-product could be potentially used as high added-value ingredients in some food or nutraceutical formulations because they are well endowed with essential nutriments required for human health.
研究了加工工业废弃的辣椒籽的化学成分和抗氧化特性及其相应的提取油。辣椒籽含有丰富的粗蛋白（18.30%）、粗油（11.04%）和膳食纤维（60.96%）。与亲水性部分相比，辣椒籽的亲脂部分显示出更高的自由基清除活性，而后者则表现出最高的还原能力。脂肪酸组成的结果表明，辣椒籽油中存在的脂肪酸主要为多不饱和脂肪酸（84.23%），亚油酸是主要的多不饱和脂肪酸（70.93%）。主要的单不饱和脂肪酸是油酸（12.18%），而主要的饱和脂肪酸是棕榈酸（11.90%）。辣椒籽油在 UV-B、UV-A 和可见光范围内具有高吸收率。由于其组成，作为辣椒加工工业的副产品，废弃的辣椒籽可能被用作一些食品或营养保健品配方中的高附加值成分，因为它们富含人体健康所需的必需营养物质。
