Abstract

The physicochemical properties of Sacha Inchi and Sacha Inchi oil and fatty acid composition of Sacha Inchi oil were analyzed.The results showed that the contents of crude protein,crude fiber,total sugar and starch of Sacha Inchi were 28.87%,24.92%,6.33% and 4.15%,respectively.The relative density(d2020),refractive index(n20d),acid value,saponification value,iodine value and peroxide value of Sacha Inchi oil were 0.928 6,1.482 2,0.46 mgKOH /g,191.4 mgKOH /g,191 gI /100 g and2.45 mmol /kg,respectively.Seven kinds of fatty acids were detected in Sacha Inchi oil,the major fatty acids were palmitic acid(3.83%),stearic acid(3.09%),oleic acid(8.39%),linoleic acid(38.11%) and linolenic acid(45.62%),and the content of unsaturated fatty acids reached 92.46%.
