A study on the effect of high pressure treatment on the water uptake of soybeans concluded that high pressure soaking can reduce soaking time. NMR analysis indicated that water mobility in a high pressure soaked soybean was more restricted and water distribution was more uniform than that of a control sample. SEM analysis revealed that high pressure can change the microstructures of the seed coat and hilum, which aids in soybean water absorption, and disrupts individual spherical protein body structures. Additionally, DSC and SDS-PAGE analysis revealed that partial proteins were denatured during the high pressure soaking.
