What does alkali do in ice cream?

Alkali, typically in the form of sodium bicarbonate (baking soda), is sometimes added to ice cream to help neutralize acidity and enhance flavor. It can also improve the texture by creating a smoother consistency, as it influences the formation of ice crystals during freezing. Additionally, alkali can contribute to a lighter color and a more appealing appearance. However, its use must be carefully controlled to avoid altering the taste negatively.
