八种葡萄籽油中主要脂肪酸的检测与分析_张云涛 . Detection and analysis of major fatty acids in the seed oil of eight different grapes

Abstract

In order to explore the differences of major fatty acids content in grape seeds of different uses,and to offer a theoretical basis for determining which specie is valuable to be extracted.This study took eight kinds of grape seeds which in three different used as materials.Supercritical CO2 fluid extraction equipment and weather chromatography was employed to identify the fatty acids content.The results indicated that,both Phoenix and Beijing jade had a higher content of stearic acid than Giant peak.Chardonnay had a higher content of oleic acid than Petit Mangseng.In red grapes,they had different content in stearic acid and linolenic acid.To various uses of grapes,the content of some fatty acids were various.This showed that varietal difference would cause a great difference in oil.
