Initial pH and buffering capacity of the pea flours
Pea grinding method | P-value | |||||||
---|---|---|---|---|---|---|---|---|
PCF | GPCF | PFF | GPFF | SEM | F | G | F × G | |
Initial pH | 6.59a | 6.57a | 6.49b | 6.48b | 0.015 | 0.001 | 0.26 | 0.65 |
Buffering capacity | 0.170a | 0.533b | 0.536b | 0.555b | 0.0068 | 0.001 | 0.001 | 0.001 |
Data are presented as LSMEANS ± SEM. PCF, pea coarse flour, obtained with a crushing roller with a 2.5 mm space; GPCF, PCF reground with a screen of 1 mm aperture; PFF, pea fine flour, obtained with hammer mill with a 2 mm screen; GPFF, PFF reground with a screen of 1 mm aperture; F, feed effect (coarse vs. fine); G, regrinding effect; F × G, interaction between feed and regrinding effects. Buffering capacity was determined with the method described by Giger-Reverdin et al. (2002). Mean values in the same row without a common superscript are significantly different at P < 0.05.
