Screw press extraction is a cost-efficient method, requiring a shorter extraction time than solvent extraction process and leaving no solvent residues in the oil product. Here, a single screw press machine at different press head temperatures was used to extract oil from Sacha inchi seeds.
Do operating parameters affect oil yields from sacha inchi seeds?
In this work, the effects of operating parameters, such as drying temperature (60, 75, 90°C) and press head temperature (60, 75, 90°C), on oil yields from Sacha inchi ( Plukenetia volubilis L.) seeds were studied using a single screw press machine.
Does Sacha Inchi oil contain polyunsaturated fatty acids?
It is found that non-dried Sacha inchi samples gave a high oil yield compared to dried samples for all press head temperatures. These Sacha inchi oils contained high content of polyunsaturated fatty acids, mainly ¦Á-linolenic and linoleic acids.
Does Sacha Inchi oil contain phenolic compounds?
The various Sacha inchi oil extracts had differences in their fatty acid levels. Additionally, the Sacha inchi oil was found to contain total phenolic compounds, which can be potentially used as an alternative source of natural antioxidants in pharmaceutical or food industries. The authors have no conflict of interest to declare.
