Focused on the discrepancy between the proportion of fatty acid in natural plant oil and that of the human's need, the study made use of the differences among various plant oil in proportion of fatty acid, established a mathematical model,and made different kinds of natural oil into proportionately nutritional oil that was suitable for vegetarian to eat and in which the ratio of saturated fatty acid, mono - unsaturated fatty acid and poly - unsaturated fatty acid was 1:1:1 and the ratio of w - 6 poly - unsaturated fatty acid and w - 3 poly - unsaturated fatty acid was 4 ~ 6: 1. Through developing the mathematical model into software, every kind of oil's mass proportion in proportionately nutritional oil could be easily gotten. As a result, modern process was adopted to get the best outcome.%针对天然植物油肪酸组成与人体适宜摄入脂肪酸比例严重不符的问题,利用各种天然植物油的脂肪酸组成有较大差异的特点,通过建立数学模型,将天然植物油调配成适宜素食人群消费的、在同一产品中同时满足了饱和脂肪酸、单不饱和脂肪酸与多不饱和脂肪酸的比例为1∶1∶1和多不饱和脂肪酸中ω-6与ω-3的比例为4∶1 ～6∶1的营养平衡的调和油.将数学模型编制成计算机软件,可方便快捷地求解出各种原料油在营养平衡调和油中所占的质量份,实现了调配手段现代化,结果最优化.
