. Conclusion
In summary, both the ratio of soluble to insoluble dietary fibre, and its associated physicochemical properties in vitro, increased with increasing hydrostatic pressure and temperature in dry and hydrated okara samples. Moreover, the effect of combined hydration, mild temperature and HHP-treatment should be considered in order to improve the SDF content and functionality of some rich-in-insoluble dietary fibre vegetable residues from the food industry for producing new food supplements or functional food ingredients.
