Why doesn't milk dissolve a skittle as much as water dose?

Milk doesn't dissolve a Skittle as effectively as water because it contains fats and proteins that can interfere with the dissolution process. Water is a polar solvent, which interacts more readily with the sugar and dye in the Skittle, breaking it down efficiently. The presence of non-polar components in milk reduces the solubility of the Skittle's ingredients compared to water. Additionally, the viscosity of milk may also slow down the dissolution process.
