If you keep raisin in pure water raisins absorbs water and swells up reason:pure water has very very little solute concentration than the raisin, so osmosis occurs, water enters the raisin, and raisin swells up(it is also called end osmosis or deplasmolysis). During the experiments it was found that optimum osmosis was found at approximately 40 °c, 40 °b of osmotic agent and in near about 132 min pretreatments also leads to increase the osmotic process in fruits and vegetables.
