Abstract

Olive pomace IDF were physical modified by high pressure homogenization (HPH) and colloid mill (CM) in this study. Moreover, the micromorphology, particle size distribution, functional groups, crystal structure and physico-chemical properties of IDF before and after the modification were analyzed. HPH group had looser morphology, more cavities and cracks, average particle size of 66.97 μm. CM group had looser morphology, more fracture, average particle size of 79.52 μm. HPH and CM modification didn’t affect IDF’s functional groups, crystal structure or crystallinity. HPH and CM groups similarly appeared characteristics absorption peaks of sugars similarly, both had celluloseⅠcrystal structure. Compared with unmodified IDF, the water holding capacity，swelling capacity and oil holding capacity of HPH group were increased by 31.70%, 78.87% and 38.92%; the Cd²⁺ adsorption capacity were increased by 7.53%; however, the NO^-₂ adsorption capacity showed no increase. Additionally, the water holding and swelling capacities, and oil holding capacity of CM group were increased by 19.93%, 47.94% and 3297%, and the NO^-₂ adsorption capacity were increased by 820%; however, the Cd²⁺ adsorption capacity didn’t increase.
