EFFECT OF CHOPPING STEP AND DRYING TECHNIQUE ON THE QUALITY OF ALKALI TREATED COTTONII (ATC)
Abstract: A research related
to the production of alkali treated
cottonii (ATC) had been carried out in order to study the effect of chopping
step and drying techniques on the quality of ATC produced. Four treatments were
applied in the experiment, namely was copping before sun drying (treatment A);
chopping after sun drying (B); chopping before mechanical drying (C); and
chopping after mechanical drying (D). The quality parameters of ATC measured
were gel strength, moisture content, viscosity, yield, and whiteness. The
results showed that the quality of ATC was significantly affected by chopping
step and drying technique, especially in ATC gel strength, viscosity and yield.
However, the effect of chopping step and drying technique was insignificant to
ATC moisture content and whiteness. Chopping seaweed before drying resulted in
higher gel strength of the ATC but lower in yield, while chopping after drying
tended to result in lower gel strength but higher viscosity and yield.
