为更加符合成人脂肪酸平衡要求，满足消费者摄入营养健康油脂的需求，以11种常见植物油和分提牛油为原料，在满足脂肪酸平衡和营养成分含量前提下，以价格为指标，使用Matlab软件进行建模编程得到营养均衡动植物调和油配方，通过单因素及正交试验设计对调配工艺进行优化，并对其进行货架期的预测。结果表明，营养均衡动植物调和油的配比为：分提牛油8.00%，玉米油16.40%，亚麻籽油72.20%，芝麻油3.40%；单价为每百毫升0.28元；实际测得饱和脂肪酸占12.78%，ω-6/ω-3多不饱和脂肪酸（Polyunsaturated Fatty Acids，PUFA）的值为5.99，在4~6:1之间，单不饱和脂肪酸（Monounsaturated Fatty Acids，MUFA）与PUFA的质量分数比为0.96，基本满足MUFA:PUFA约为1:1，所配得的调和油脂肪酸比例与期望值相符；最佳调配工艺为：搅拌时间30 min、TBHQ添加量15 mg、搅拌温度20 ℃；营养均衡动植物调和油保质期为18个月。研究结果为营养平衡健康的调和油开发奠定了理论依据，为食用油企业新产品研发提供新的途径。

In order to better meet the requirements of fatty acid balance for adults and meet the demands of consumers for nutritional and healthy oils, 11 kinds of common vegetable oils and fractionated butter were used as the raw materials. On the premise of meeting the requirements of fatty acid balance and nutrient content, the price is taken as the index, and the MATLAB software was used for modeling and programming to obtain the formula of nutritionally balanced animal and vegetable blend oil. The blending process was optimized by the single factor and orthogonal experimental designs, and the shelf life was predicted. The results showed that the proportion of nutritionally balanced animal-plant blend oil was as follows: fractionated butter 8.00%, corn oil 16.40%, flaxseed oil 72.20%, sesame oil 3.40%; the unit price was 0.28 yuan per 100 ml, The actual measurements revealed the composition as follows: saturated fatty acids, 12.78%; ω-6/ω-3 polyunsaturated fatty acids (PUFA) ratio, 5.99 (which was between 4 and 6:1); the mass ratio of monounsaturated fatty acids (MUFA) to PUFA, 0.96 (which basically meets the required MUFA-to-PUFA ratio of 1:1). The fatty acid ratio of the blend oil was consistent with the expected value. The optimum blending process was as follows: stirring time, 30 min; TBHQ addition, 15 mg; stirring temperature, 20 ℃. The nutritionally balanced animal and plant blend oil had a shelf life of 18 months. The results of this study lay a theoretical foundation for the development of nutritionally balanced and healthy blend oils, and provide a new path for edible oil enterprises to develop new products.
