Abstract

The oil content of almond and the fatty acid composition and VE of almond oil from eight producing areas in Loess Plateau Region(QingYang,XiXian,AnSai,ZhenYuan,HuaChi,LingTai,FangShan,LingYou)were studied.Results: The oil content of almond from the eight areas are from 42.642% to 53.569%. The fatty acid compositions of the almond oil from different regions are the same,they all contain linoleic acid,oleic acid,palmitic acid,stearic acid and palmitoleic acid;the percentage of unsaturated fatty acids are all above 94%,among which the content of oleic acid and linoleic acid are above 62.8% and 24% respectively.The VE content of the oil is from 19.4mg/100g to 55.833 mg/100g.Taking it all round,the best habitat for bitter almond is LinYou.This study provides a scientific basis for the industrialization and base construction of bitter almond.
