“…The percentage volume of pores is associated with firmness and crispness and promotes the texture of mealiness (Harker and Suthrland, 1993). The structure of the material is important for supplying and removing the gases (O 2 and CO 2 ) required for intracellular respiration (Ho et al, , 2010(Ho et al, , 2011Mebatsion et al, 2008) and it also determines water transport mechanisms (Chiralt andTalens, 2005, Mendoza et al, 2007). Tissue pre-treatments leading to changes in structure may significantly alter the effectiveness of further food processing techniques.…”
