Summary
This laboratory study characterised Indonesian sacha inchi seed oil across multiple dimensions, including a detailed fatty acid profile dominated by omega-3 (48.5%) and omega-6 (34.8%), substantial vitamin D content (899.46 mg/100 g), and very strong in vitro antioxidant activity (IC50 of 8.859 ppm). The oil demonstrated no microbial or heavy-metal contamination and tested positive for flavonoids, triterpenoids, and steroids, supporting its potential use in cosmeceutical or nutritional applications.
UK applicability
Whilst sacha inchi is not cultivated commercially in the United Kingdom, these analytical findings on oil composition and antioxidant properties may be relevant to UK importers, supplement manufacturers, or cosmetic formulators considering sacha inchi as an ingredient. The data provide a baseline for quality and safety assessment if the ingredient enters UK supply chains.
Key measures
Fatty acid profile (omega-3, omega-6, omega-9 percentages); vitamin A, D, and E content (mg/100 g); antioxidant activity (IC50 value in ppm); physicochemical parameters (density, acid number, peroxide value, iodine value, refractive index); phytochemical screening; microbial and heavy-metal contamination tests
Outcomes reported
The study characterised sacha inchi seed oil from Indonesian sources, determining its fatty acid composition, vitamin content, and in vitro antioxidant activity. Quality parameters, phytochemical constituents, and microbial and heavy-metal contamination were also assessed.
