Vacuum impregnation (VI) is a food preparation technique that changes food composition. In recent studies, VI was used to change the properties of food with regards to nutritional, sensory, shelf life and physicochemical characteristics (Chiralt et al., 2001; Guamis et al., 1997; Lin, Leonard, Lederer, Traber, & Zhao, 2006). VI is characterized by replacing the initially occluded air in pores of the fruit or vegetables with a liquid, which is the impregnation solution. With pressure gradients, air of the porous fraction is released until atmospheric pressure conditions are restored and the external liquid phase penetrates the plant tissue.
