Table 3 Distribution of pentosans between the different fractions of used thin stillage after solid–liquid separation (centrifugation with 4950g for 20 min; mean values of triplicates with standard deviation)
Fraction | Dry matter (DM)a | Pentosan content | Share of DM | Share of pentosans |
|---|---|---|---|---|
% | %DM | % | % | |
Thin stillage | 16.77 ± 0.03 | 14.02 ± 0.06 | 100 | 100 |
Diluted thin stillage (1:1 w/w) | 8.37 ± 0.08 | 14.39 ± 0.08 | 100 | 100 |
Liquid phase of thin stillage after centrifugation | 5.36 ± 0.36 | 21.35 ± 0.40 | 49.2 ± 0.9 | 78.4 ± 4.6 |
Solid phase of thin stillage after centrifugation | 22.49 ± 0.10 | 5.78 ± 0.12 | 52.9 ± 0.5 | 21.7 ± 0.6 |
