Effect of Ash Content on Color of Processed Cane Sugar

Abstract

Samples from all three columns of the factory were taken at fixed time
intervals and analyzed for color, pH and conductivity. Raw sugar, melt liquor,
clarified liquor, filtrate liquor, de-colorized liquor and refined sugar; color,
(ICUMSA) levels were found 727, 641, 335, 206, 80 and 50 respectively:;
with a corresponding ash content of 0.17, 0.14, 0.13, 0.12, 0.11 and 0.10 .
The conductivity ash was measured for A- sugar and found to be 0.12%,
whereas the standard value is 0.1%. The obtained results showed that the ash
content lied within the standard range. The high amount of reducing sugars
cause or rise the color as it was formed at Assalaya sugar Factory. When, RS
was 0.25 the color was 45 ICUMSA, but when the RS of the raw sugar was
0.77 the color appear as to be 776 ICUMSA
