婴儿配方奶粉中脂肪母乳化的调配研究

Study on preparing the fat of imitation breast milk in infant formula

利用MATLAB优化工具箱中的线性约束优化函数求解脂肪酸配比合理且植物油总价最小时的配比,得到了10组配方中所用五种原料油(椰子油、棕榈油、葵花仁油、大豆油、紫苏籽油)的配比和最优价格。经气相色谱分析,10组配方的脂肪酸含量均符合婴儿配方食品标准,其中配方10的脂肪酸含量较其余九组更接近人乳脂(HMF)。配方十中5种原料油(椰子油、棕榈油、葵花仁油、大豆油、紫苏籽油)在婴儿配方奶粉中的配比分别为13.6%,50%,14%,21%,1.4%,最优价格为9.53元/kg。

A linear restraint function in Matlab optimization toolbox and programming in MATLAB was used to solve the vegetable oils formula at a reasonable fatty acids ratio and the lowest price and establish mathematical model.The determination results of fatty acids in vegetable oil by gas chromatography showed that the fatty acids composition of formula was according with the standard of infant formula and the composition as close as possible to that of HMF,especially formula 10.The optimized formula is 13.6%coconut oil,50%palm oil,14% sunflower oil,21%soybean oil,1.4%perilla seed oil,the optimized price is 9.53 yuan/kg.
