The seeds of the sacha inchi plant (Plukenetia volubilis L.) have been extracted using the cold pressing method at a temperature of 45°C and a pressure of 600 bar or 60 MPa. Seeds come from sacha inchi plants grown at an altitude of 200 and 500 masl each with an oil volume of 100 ml. Testing of absorbance properties will be carried out using the UV-Vis spectrophotometer technique. So that the absorbance spectrum pattern are expected to provide information on the characteristics of the substance content possessed by the sacha inchi plant, namely lipids/fatty acids, proteins, tocopherols, phytosterols, phenolic components, fiber, antioxidants, carbohydrates, vitamins, polyphenols, and minerals.
