摘要：
Sacha Inchi oil was studied for its physicochemical characteristics, chemical composition, radical scavenging activity and storage stability. The fatty acid composition was studied by gas chromatography flame ionization (GC FID) and the analysis showed that the oil is highly enriched in a linolenic (43.5%) and linoleic (39.6%) acids. The tocopherol content in the oil analyzed by high performance liquid chromatography/ ultraviolet visible detector (HPLC/UV VIS) was also high (161.87 mg.100 g(-1)). Both DPPH and ABTS assays detected relatively high radical scavenging activity. After twelve months of storage, the oil showed relatively good storage stability. The results will help guide further investigation of the health benefits of Sacha Inchi oil for the population and the development of better edible oil products and nutraceuticals.
