鸦胆子的油脂品质分析

本文分析了鸦胆子的主要组份和鸦胆子仁油的一些主要理化指标,测定结果表明鸦胆子粗脂肪的平均含量为20.5%(干基),鸦胆子仁油的粗脂肪含量高达56.9%.鸦胆子的粗蛋白含量为4.4%(鸦胆子仁的粗蛋白含量为1.6%).鸦胆子仁油的一些理化指标皂化值为198.0,碘值为98.3,不皂化物0.75%.经气相色谱分析,鸦胆子仁油主要由棕榈酸、硬脂酸、油酸、亚油酸和亚麻酸构成.其中油酸含量达到63.3%,亚油酸为21.2%.因此,鸦胆子仁油很可能是一种有开发价值的野生新油源.

ANALYSIS ON OIL QUALITY OF BRUCEA JAVJINICA(1.).MERR

The components of Brucea javjinica(1.)Merr.and the physicochemical indexes of its oil were analyzed.The results showed that crude fat contents in Brucea javjnica(1.)Merr.and its kernel were 20.55 and 56.9% respectively.The crude protein in Brucea javjnica(1.)Merr.and its kernel were 4.45 and 1.6% respectively.The main physical and chemical properties of the kernel were analyzed.The soaponification value(SV)was 198,the iodine value(IV)was 98.3.The content of unsoaponificable matter was 0.75%.The main fatty acid components of Brucea javjnica(1.)Merr.kernel oil were palmitic acid(P),stearic acid(St).oleic acid(O),linoleic acid(L)by gas chromatography analysis.The contents of oleic acid and linoleic acid could reach 63.3% and 21.2%.On the basis of the analysis data,Brucea javjnica(1.)Merr.kernel oil would be developed and utilized in the future.
