不同品种紫苏种子营养成分及脂肪酸组分分析_张志军 . Analysis on Nutrition Constituents and Fatty Acid of Different Perilla Seeds

Abstract

This article studies crude fat,protein and cellulose content in ten different kinds of perilla seeds,and analyzes the fatty acids by GC method.The result shows that there are significant differences in nutrients among ten varieties,fat coentent range from 34.0% to 45.2%,protein from 18.5% to 21.8% and cellulose from 19.0% to 25.1%.The seed oils contain palmitic acid(0.18% ~1.42%),stearic acid(0.32% ~1.86%),oleie acid(11.42% ~23.06%),linoleic acid(9.97% ~13.02%) and α-linolenic acid(58.48% ~71.23%.The unsaturated fatty acids account for 93.32% ~95.43% in total fatty acids.ZS-5 and ZS-9 are screened as high-quality breeding materials for oil development and α-linolenic acid industrial extractions because of their higher content of crude fat and large proportion of α-linolenic acid.
