Analysis of Nutritional Composition of Bitter Almond from Different Growing Areas

The nutritional and medicinal value of bitter almond from different growing areas was compared by analyzing their nutritional composition. The results showed that protein content was 19.6%~25.7%,fat content was 40.0%~46.7%,total sugar content was 3.2%~5.2%,crude fiber content was 9.1%~10.8% and amygdaline content was 4.7%~5.0% in bitter almond from different growing areas. The ratio of essential amino acids to total amino acids(EAA/TAA)in bitter almond from different growing areas ranged from 28.0% to 28.9%. The order of score of ratio coefficient of amino acid(SRC)in these growing areas from large to small was Chaoyang in western Liaoning and Chifeng in Inner Mongolia,Gansu and Ningxia in Northwest China,Hulunbeir in Inner Mongolia,respectively. The range of unsaturated fatty acid/total fatty acid(U/T)values of bitter almond from different growing areas were 93.849%~95.034%. All the results suggested that the protein nutritional value of the bitter almond from Chaoyang in western Liaoning and Chifeng in Inner Mongolia was the highest,the fatty acid nutritional value of the bitter almond from Gansu and Ningxia in Northwest China was the best and the amygdaline medicinal value of the bitter almond from Chaoyang in western Liaoning and Chifeng in Inner Mongolia was the greatest.
