Bound water is that fraction of water present in food materials which is either physically or chemically attached with other compounds and solid structural matrix. Bound water shows several extraordinary characteristics. Bound water shows remarkable discrepancy in physic-chemical properties including molecular mobility, dielectric nature, vapor pressure, boiling and freezing temperature, during thermodynamic processing of foods. Several distinctive features of bound water that make it distinct from free water have been discussed in this chapter.
