Abstract

Swida wilsoniana is an important woody oil plant of which the whole fruits contain oils. Main contents of fruits from swida wilsoniana were analyzed through chemical means to 46 samples from different areas. These fruits have an average moisture content of about 8.19% after natural dried. The oil content is about 28.02% (dry basis) or more. The protein content is 7.25% (dry basis) and the cellulose content is about 14.18%. Through theoretical calculation and the one-dimensional pressing device, the conditions of cold pressing process and performances of fruits from swida wilsoniana had been studied. The results show that swida wilsoniana fruits suffering natural dried are suitable for direct pressing, which guarantees a higher oil quality. The volume of fruits fed into pressing device had little effect on pressures of oil squeezed out , fruits crushed and critical compression, and the value of those pressures were 55.7 MPa, 71.5 MPa and 80 MPa individually. At the critical pressure of 80 MPa and the compression ratio of 3.14, residual oil of meal is 6.5%. The fruits oil has about 72% unsaturated fatty acids, of which approximately oleic acid is 29.83%, linoleic acid is 39.15%, and linolenic acid is 2.59%.
