Rules for determining fructan type*
1.
DP 3.6-4 (CF = 1.233, #1 in Table 2-6 in Part 2) - Presence of GF
3
and GF
4
with the absence of peaks after ~36
minutes.
2.
DP 5.49-10 (CF = 1.068, #2 in Table 2-6 in Part 2) - Presence of both GF
3
and GF
4
, along with peaks after ~36
minutes.
3.
DP 11-50 (CF= 0.9526, #3 in Table 2-6 in Part 2) - Absence of GF
3
and GF
4
and presence of peaks after ~ 36 minutes.
*Note the gap between DP ranges 1 & 2 align to the known commodities used at this time.
Additional Observations
1.
Absence of significant peaks after ~5 minutes means scFOS (DP 3.6). See Figure A-1- in Appendix A for an
example.
2.
Oligofructose containing materials derived from the partial hydrolysis of chicory inulin often display a characteristic
peak with significant tailing at ~ 5 minutes. See Figure A-2 in Appendix A for an example.
3.
Presence of significant peaks after ~36 minutes means it cannot be scFOS or oligofructose. Contains some higher DP
inulin type material. See Figure A-3 in Appendix A for an example.
Example determinations:
Several examples are demonstrated in Appendix A.
