野茉莉种仁与种子油的营养成分及理化特性研究

Composition and some characteristics of the seeds and the seed-oil of Styrax tonkinesis

分析了野茉莉种仁与种子油的化学成分,野茉莉种仁含58·60%油,9·35%粗蛋白,灰分2·37%。还分析了野茉莉种仁的氨基酸成分,种子油脂含有10种主要脂肪酸,其中的不饱和脂肪酸以油酸29·64%、亚油酸52·65%和亚麻酸6·29%为主,种子油的物化指标为:皂化值165·32,碘值125·54,酸价1·16,折光指数1·4967(20℃),相对密度0·9468。

The composition of Styrax tonkinesis seeds and seeds-oil were analyzed.The seeds contain 58.60% oil,9.35% protein,2.37% ash.The amino acids compositions of the seeds were determined.Ten fatty acids were identified in Styrax tonkinesis seed-oils.Approximately 90% of the fatty acids were unsaturated with oleic acid 29.64%,linoleic acid 52.65% and linolenic acid 6.29%.The refractive index of the seed-oil,nd20=1.4967,reality density=0.9468,the saponification value=165.32,acid value=1.16,iodine number=125.54.
