Sacha inchi seed oil is a food matrix rich in bioactive constituents, mainly polyunsaturated fatty acids. In this study, the characteristics of color, carotenoid content, tocopherols, and volatile aroma compounds in eight sacha inchi seed (Plukenetia volubilis L.) oil accessions were evaluated. Results showed that the oil obtained from the accessions presented a lightness and chroma of 91 to 98 units and 6 to 10 units respectively, while the hue angle ranged between 93 to 97 units. The total carotenoid content in the different accessions ranged from 0.6 to 1.5 mg/kg, while γ- and δ-tocopherol ranged from 861.6 to 1142 mg/kg and 587 to 717.1 mg/kg. In addition, the total content of tocopherols varied between 1450 and 1856 mg/kg and the δ/γ ratio ranged between 0.58 and 0.70. The oils from the accessions PER000408 (861 µg/kg) and PER000411 (896 µg/kg) were those with the higher volatile concentration, especially 1-hepten-3-ol, 2-nonanol, (E)-3-hexen- 1-ol, (E)-2-hexenal, and 1-hexanol. In this study, the variability of the oil obtained from 8 accessions were observed, from which promising accessions can be selected for continuous investigations of the new sacha inchi seed genotypes.
藜麦籽油是一种富含生物活性成分的食品基质，主要是多不饱和脂肪酸。本研究评估了 8 个藜麦种子（Plukenetia volubilis L.）油品种的颜色、类胡萝卜素含量、生育酚和挥发性香气化合物特征。结果表明，品种间获得的油具有 91 至 98 单位的明度和 6 至 10 单位的彩度，而色调角在 93 至 97 单位之间。不同品种的总类胡萝卜素含量在 0.6 至 1.5mg/kg 之间，而 γ-和 δ-生育酚含量在 861.6 至 1142mg/kg 和 587 至 717.1mg/kg 之间。此外，生育酚总量在 1450 至 1856mg/kg 之间变化，δ/γ 比值在 0.58 至 0.70 之间。品种 PER000408（861μg/kg）和 PER000411（896μg/kg）的油具有较高的挥发性浓度，特别是 1-庚烯-3-醇、2-壬醇、（E）-3-己烯-1-醇、（E）-2-己烯醛和 1-己醇。在这项研究中，观察了从 8 个品种获得的油的可变性，可以从中选择有前途的品种，对新的藜麦种子基因型进行连续研究。
