Abstract

This work analyzed the fat composition and the fatty acid composition of ten Carya illinoensis （pecan）cultivars by using gas chromatography and a correlation analysis. Results showed that fat content between 69.11%-78.19% for all pecan kernels，including palmitic（C16:0），stearic（C18:0），oleic（C18:1），linoleic（C18:2），linolenic（C18:3），arachidic（C20:0）. And kernel content of the seed ranged from 36.79%-59.49%. Fatty acid content was greater than 90.00% with oleic and linoleic percentages having a significant negative correlation（r = －0.994 2，P＜0.01）. For pecan oils，the correlation analysis showed significant differences（P＜0.05）in the fatty acid contents. The mono unsaturated fatty acid（MUFA） content of the fat was 73.01%－58.76%；the polyunsaturated fatty acid（PUFA） content was 32.20%-19.69%. Also，oil yield and shelling percentage had a significant positive correlation（r= 0.674 0，P＜0.01）；whereas，rate of seed and peel thickness was not significant.［Ch，3 fig. 3 tab. 12 ref.］
