Sacha Inchi Oil Characteristics and Applications
Summary
Sacha Inchi oil, extracted from the seeds of Plukenetia volubilis, is distinguished by its exceptionally high levels of polyunsaturated fatty acids, notably α-linolenic acid (C18:3 n-3) and linoleic acid (C18:2 n-6). This unique lipid composition underpins its cardioprotective, anti-inflammatory and neuroprotective potential. In addition to essential fatty acids, the oil contains significant concentrations of tocopherols and phytosterols, contributing to its antioxidant capacity and functional stability. Physicochemical parameters—such as a high iodine value, low melting point and saponification number indicative of long-chain unsaturated triglycerides—further define its quality and processing characteristics. Owing to its proneness to oxidation, advanced strategies including microencapsulation have been employed to preserve bioactivity and extend shelf life. Beyond its status as a nutritional supplement, Sacha Inchi oil is integrated into functional foods, nutraceuticals and cosmetic formulations, where its emollient and regenerative properties are valued. Cultivation of this underutilised oilseed crop also offers agroecological resilience and socioeconomic opportunities in tropical regions, aligning with global priorities for sustainable and diversified food systems.

Sacha Inchi Oil Characteristics and Applications publication trend
The graph below shows the total number of articles in sacha inchi oil characteristics and applications across all publications each year (not limited to Nature Index journals).
Technical terms
Alpha-linolenic acid (ALA): An essential omega-3 polyunsaturated fatty acid abundant in Sacha Inchi oil, linked to anti-inflammatory and cardioprotective effects.
Linoleic acid: An essential omega-6 polyunsaturated fatty acid prevalent in Sacha Inchi oil, involved in cellular signalling and membrane integrity.
Tocopherols: Lipid-soluble antioxidants (vitamin E variants) that protect oils from oxidative degradation.
Microencapsulation: A technique for enclosing bioactive compounds within microscopic carriers to enhance stability and control release.
Iodine value: A measure of the degree of unsaturation in fats and oils, indicating both nutritional quality and susceptibility to oxidation.
