Wet-end StarcheS world pulppaper54 the new cereal based wet-end starches performed at least as good as their potato counterparts in a variety of retention systems. conclUSIon The new cereal based wet-end starches performed at least as good as their potato counterparts in a variety of retention systems. In most cases the formation is improved when using the cereal based products resulting in improved strength. Furthermore the zeta-potential of the pulp is much less affected even if the nominal degree of substitution of the wheat based product is higher than that of the potato based product. This may be explained by less occupation of space on the fibres but by more stretch into the water phase. Logically this allows more bridging between particles and also explains the improved retentions. As a consequence more starch can be added before the pulp is charge neutralised or that there is more room for other cationic additives. CLiBond wet-end starch when compared to a potato starch with the same cationic degree of substitution has been tested positively in various wet-end applications.
