Composite emulsifier with emulsification effect and water retention effect and application thereof

The invention relates to a composite emulsifier with an emulsification effect and a water retention effect. The composite emulsifier is prepared from the following raw materials in percentage by weight: 25-40% of water, 10-30% of sorbitol, 10-30% of glycerol, 5-15% of sucrose fatty acid ester, 5-15% of glycerin monostearate, 5-15% of sorbitan monostearate and 3-10% of polyoxyethylene sorbitan monostearate, wherein the HLB value of the sucrose fatty acid ester is 16. In addition, the invention also provides application of the composite emulsifier in preparation of baked foods. The composite emulsifier has the advantages of achieving a rapid emulsification effect, meanwhile achieving a water retention effect on foods, ensuring fluffy and wet product texture and uniform and exquisite tissues,and improving the quality. 本发明涉及种同时具有乳化和水分保持作用的复配乳化剂，包括以下质量百分数的原料：25-40％的水、10-30％的山梨糖醇、10-30％的甘油、5-15％的蔗糖脂肪酸酯、5-15％的单硬脂酸甘油酯、5-15％的山梨醇酐单硬脂酸酯以及3-10％的聚氧乙烯山梨醇酐单硬脂酸酯，其中，蔗糖脂肪酸酯的HLB值为16。此外，本发明还提出了上述复配乳化剂在烘焙食品制备中的应用。本发明具有的优点在于在快速乳化作
