2.2. Sample preparation
CS–CO blends with 30% moisture content (wet basis, w.b.), were
prepared by simultaneously adding CO, in a proportion of 1, 5 and
10 g/100 g of CS and distilled water to the CS. Continuous stirring in
a laboratory blender at medium speed, was applied during mixing.
After mixing, blends were sieved (US Standard Sieve No. 30 ASTM
E-1. 0.6 mm), in order to eliminate lumps. The samples were packed
in plastic containers, sealed and left overnight to reach equilibrium
