英文品名：Total Dietary Fibre Controls Assay Kit
规格型号：Sufficient for 6 Controls
For use with the Total Dietary Fibre Assay Kit. Contains barley?-glucan, high amylose maize starch, wheat starch, casein, pectin andlarch galactan. Wheat arabinoxylan is available on request.
Total Dietary Fibre Controls:
1. β-Glucan (barley); 1 gram; TDF 99.9 %.
2. High Amylose Maize Starch (native);
10 grams; TDF 29.3 %.
3. Wheat Starch; 10 grams; TDF 0 %.
4. Casein; 5 grams; TDF 0 %.
5. Pectin; 1 gram; TDF 86.5 %
6. Larch Galactan; 1 gram; TDF 83.5 %.
NOTE:
AOAC Procedure 985.29 states that for pectin and larch galactan, the
recovery of TDF is 100 %. This relates to the fact that the recovery
of these polysaccharides in the standard TDF assay (i.e. with enzymes)
is exactly the same as that obtained in the assay when enzymes are
not included. The actual recoveries of these two polysaccharides
are as shown above. The less than 100 % recovery is not due to
contaminating enzyme activities in the α-amylase, amyloglucosidase or
protease used in the assay procedure, but simply due to losses in the
precipitation and recovery steps.
