Significant reductions of fat absorption in deep-fat fried BBFBs were achieved by adding BSDF to the batter. The inhibition of fat absorption in fried BBFBs depended on the level of BSDF addition in
the batter with 6% BSDF showing the maximum effect. The fibers present in BSDF together with egg white in the mixed batter prevented the outward migration of the moisture from the core to the
crust and concomitantly blocked inward oil diffusion. This is because the tight and firm egg white protein membrane, reinforced by the fibers, inhibited the evaporation of moisture in the crust and the core due to favorable moisture-holding capacity. The crust also served as a barrier to entrap internal moisture. Therefore, the results obtained from this study may contribute to the scale-up
manufacture of the low-fat fried breaded and battered fish products.
