Tween has the functions of emulsifying, stabilizing, dispersing, helping foaming and stabilizing the crystal structure of oils. It is often used in combination with other emulsifiers. It has obvious hydrophilicity. Because of its stronger ability to replace proteins, its effect of reducing interfacial tension is far Stronger than monoglyceride. Because of its thermal stability and hydrolysis stability in water, the addition of ice cream can emulsify, disperse and stabilize the ice cream, and increase the volume of the ice cream. The air is easy to penetrate into the emulsion, forming a fine pore structure, increasing the volume, and producing The ice cream is stable in shape and has a loose texture.
The replacement of monomer emulsifiers with composite emulsifiers is the development trend of ice cream production today, and it is very common in production. The addition amount is generally 0.1%-0.3%. The compound emulsifier is not only convenient to use, but also can obtain more uniform quality ice cream products. The compound emulsifier system can achieve the best protein substitution effect.
