摘　　要：针对GB/T 20569—2006附录A规定的测定稻谷脂肪酸值试样制备方法的某些缺点提出了改进的方法,采用改进法和国标法分别测定了60个稻谷样品的脂肪酸值,建立了改进法的校正模型:Y标=0.914 6X改+6.332 2,并用10个样品验证该模型.结果表明:改进法测定的稻谷脂肪酸值经校正后所得结果与国标法测定的稻谷脂肪酸值的差值均在允许误差之内,两者线性关系显著(R2=0.769 7),使用改进法测定脂肪酸值是可行的.In this paper, we proposed an improved method for determining fatty acid value of paddy samples to overcome the disadvantages of the standard method described in appendix A of GB/T 20569-2006. We determined the fatty acid values of 60 paddy samples respectively by the improved method and the standard method, and established the correlation model of the improved method. The correlation model was Y=0.914 6X＋ 6.332 2,RZ=-0.778 3,and was validated by 10 samples. The results showed that the difference between the correlated result of the paddy fatty acid value determined by the improved method and the fatty acid value determined by the standard method was in an allowable error range; and the two results had a significant linear relationship （R2=-0.769 7）. Accordingly, the improved method was feasible.
