Breast milk lipid substitute and preparation method and application thereof

The invention relates to a breast milk lipid substitute and a preparation method and application thereof, and the breast milk lipid substitute is formed by carrying out five-membered ester exchange on bala fish oil stearin, camphor tree seed kernel oil, linolenic acid grease, ARA grease and DHA grease. According to the invention, an excellent breast milk lipid substitute is constructed through transesterification. The prepared breast milk lipid substitute has the characteristics that the triglyceride structure and the fatty acid composition are similar to those of breast milk, the content of palmitic acid at the site 2 is greater than or equal to 30%, energy can be quickly supplied, essential fatty acids in a body can be balanced, ARA and DHA can be supplemented, and the like, and the breast milk lipid substitute can be widely applied to infant foods. 一种母乳脂质替代品及其制备方法和应用，所述的母乳脂质替代品，是由巴沙鱼油硬脂、樟树籽仁油、亚麻酸类油脂、ARA油脂和DHA油脂进行五元酯交换而构成的。本发明通过酯交换构建了一种优良的母乳脂质替代品。本发明所制备的母乳脂质替代品具有甘油三酯结构和脂肪酸组成与母乳相似、2号位棕榈酸含量≥30％，可快速供能，平衡体内必需脂肪
