光皮树果实内含物含量的测定与综合利用

Component determination of Swida wilsoniana fruits and comprehensive utilization

本研究在分析光皮树果实主要内含物成分的基础上,提出了光皮树果实综合利用的途径。光皮树是一种优良的木本油料植物,其果实全果含油,是一种重要的高油低蛋白的油料。分析结果表明:光皮树果实的含油量在30.15%(干基)以上,其中果实种皮含油率约为37.76%,种籽的含油率约为15.25%,蛋白质含量为5.38%(干基),淀粉含量为12.22%(干基),纤维素含量为14.18%(干基);光皮树果实油是一种优良的木本植物油,采用德国进口的CA59G型榨油机压榨光皮树果实,得到光皮树果实油和饼粕,其果实油中不饱和脂肪酸含量达72%左右,其中油酸约为29.83%,亚油酸约为39.15%,亚麻酸为2.59%,饼粕中蛋白质和残油均不多,其中残油小于4%,可作为一种有机肥料,亦可以作为一种颗粒燃料。

Based on the components analysis of Swida wilsoniana fruits, the approaches to comprehensive utilization of S. wilsoniana fruits were presented. S. wilsoniana is an important high oil and low protein woody plant that the whole fruits contain oils. The results show that the oil content of the fruits was about 30.15% （dry basis） or more, while the oil content in the fruits seed coat was about 37.76%, the oils content in seed kernel was about 15.25%; the protein content was 5.38% （dry basis） and the starch content was 12.22% （dry basis）, the cellulose content was 14.18% （dry basis）. The fruits oil from S. wilsoniana is a new kind of excellent woody oil pressed by the imported equipment from Germany （CA-59G）. The fruits oil had about 72% unsaturated fatty acids, of which approximately oleic acid was 29.83% and the linoleic acid was 39.15%, the linolenic acid was 2.59%. Meanwhile, a low content of protein and residual oil was no more than 4%, which can be used as an organic fertilizer or a particle fuel.
