Study on composing component of amino acids and essential oil fatty acids in satsuma orange peel
Citrus is a major kind of fruit in China,its peel is a high valuable source because of abundant essential oils, pectins, flavonoids, etc. Amino acids of protein in satsuma orange peel were analysed by automatic technology.The test result indicated that protein content was 3.446% （ dry substance, m/m） and essential amino acids content was 1.239%.The essential amino acids content of protein was 35.956%,less than which of soybean protein, Met and Cys were limited amino acid in peel.Fatty acids in satsuma orange peel were extracted by Soxhlet extraction apparatus,at the same time, separated and identified by GC-MS. 11 fatty acids identified in peel oil consist of d saturated fatty acids （26.06%）and 5 unsaturated fatty acids（66.20% ）.The saturated fatty acids was mainly composed of hexadecanoic acid （19.75%）, but the unsaturated fatty acids were mainly composed of linoleic acid（37.14% ） and linolenic acid（ 19.06% ）.
