Emulsification: Soy lecithin acts as an emulsifier, helping to evenly distribute fats and other ingredients in the liquid, preventing separation.

Improved Texture: It can enhance the smoothness and creaminess of your drink by preventing clumping and ensuring a consistent texture.

Mixability: Soy lecithin aids in better mixing, reducing the need for vigorous shaking or stirring.

Shelf Life: It can extend the shelf life of the drink powder by stabilizing the mixture.
