The crude fat contents and oil fatty acid compositions of four species of almond kernel in different harvest time were determined and analyzed. The results showed that the crude fat contents in different species of almond kernel were accumulating and rising,and the difference in the crude fat contents was significant( p < 0. 05),indicating that the harvest time had a great influence on the crude fat content of amond kernel,and the more mature the kernel,the better the accumulation of crude fat. Four fatty a...
