FFA and moisture of GBR increased after UHP treatment.
The peak values of bioaccessible minerals were at 300 MPa whereas it decreased at 500 MPa.
Starch gelatinization of GBR occurred at 300 MPa and was further enhanced at 500 MPa by SEM.
All TPA parameters other than springiness of GBR were highly correlated (p < 0.01) after UHP.
Minerals bioaccessibility had a positive relationship with hardness, chewiness and springiness by CCA.
