Slices of beetroot release pinkish colour in water due to osmosis. When the movement of solvent molecules (water) occurs from higher to lower concentration via semi-permeable membrane the pigment molecules of beetroot are released in water.
The raisins get swollen when kept in water (Imbibition) is an example similar to osmosis.
