Description

technical field [0001] The invention relates to the field of food additives, in particular to a polyoxyalkyl ether derivative of diacetyl tartrate mono-diglyceride, its preparation method and application. Background technique [0002] Diacetyl tartrate mono-diglyceride, as a green surfactant, has strong emulsifying, dispersing, and anti-aging effects. It is used as a food emulsifier with high safety performance. It can be widely used in the preparation of bread, pastry and steamed buns, etc., to increase the elasticity, toughness and gas retention of dough, and effectively increase the volume. An emulsifier used in margarine can effectively control the structure of cream, improve product properties, taste and flavor, and prolong storage and freshness. [0003] Diacetyl tartaric acid mono-diglyceride emulsifiers are often added as stabilizers in dairy products and milk drinks, especially compounded emulsifiers. For example, Chinese patent CN 102028028 A discloses a dairy pr...
