Dry-base moisture load of the fibres varied between 0.048 g/g and 0.093 g/g (Table 3), and WBC ranged from 3.3 g/g for CE to 11.5 g/g for FP. The ratio of water to fibre in the binary filler mixture for sucrose replacement (Eq. (1)) ranged between 3.02 for CE and 10.97 for FP. Corresponding mixtures of fibre and water were allowed to swell overnight, and 41.3 g thereof (see Table 1) were incorporated in the formulation.
