- All values are reported on an extractive free basis, otherwise known as alcohol-insoluble residue (AIR), except for total extractives, which are reported on a dry weight (DW) basis. Literature range adapted from [19, 30, 36]. It is important to note here that the reason cellulose and hemicellulose values fall outside of the literature range is likely due to the inclusion of the large “other” fraction included in the AIR calculation. Further, the mixed-link β-glucan (MLG) fraction was also subtracted from the cellulose fraction, which was not the case in literature range studies
