Abstract
A method of determining the mass balance closure quantification of fiber of a sample includes using an extraction technique followed by analysis of non-saccharide soluble organics (solubles). In conjunction with traditional analyses of protein, fat, starch, and ash, this method accurately determines fiber by mass closure calculation. On pre and post processed grain materials the calculation is fiber=100−protein−fat−starch−ash−solubles. The accurate determination of fiber determines the converted fraction for the generation of D3 RINS by the Environmental Protection Agency's in situ renewable fuels pathway.
Claims11
A method of quantifying fiber content in cellulosic feedstock by mass closure, the method comprising:
- determining moisture content of a sample of cellulosic feedstock and if the moisture content is greater than 15 wt-%, drying the sample to below 15 wt-% moisture;
- determining protein, fat, starch, and ash content of the sample on a dry weight basis;
- determining non-saccharide soluble organics content of the sample by:
- extracting lactic acid, glycerol, and acetic acid from the sample;
- and
- measuring amount of the lactic acid, the glycerol, and the acetic acid;
- and
- calculating the fiber content as 100−(% dry weight protein+% dry weight fat+% dry weight starch+% dry weight ash+% dry weight non-saccharide soluble organics).
