RCP: raw coffee parchment; MCP: medium coffee parchment; FCP: fine coffee parchment. Values are mean ± SD from three replicates. Values in a column with different superscript letters are significantly different (p < 0.05) at 5% level of significance using Duncan’s multiple-range test. Repeated superscript letters indicate that the means were not significantly different (p > 0.05). SD: standard deviation; BE: biological efficiency.
