3.5. Effectiveness of fortification
A well-designed enriching component should have high effi-
ciency, thus to evaluate the effectiveness of enrichment with
bioactive ingredient the fortification factor (FF) was proposed. As
shown in Fig. 2 significant differences between FF values for CE, BE,
DE and AE were observed. Taking into account CE it can be
concluded that values of FF in all tested methods strongly dependent
of QL percent (linear relationships were observed). Similar
relationships were observed for BE, however FF values (in except
CHEL) were significantly higher than those determined for CE. It
may suggested that these active compounds can be extractable
already during mastication. Taking into account AA and RED the
highest FF values were determined for QL4. On the other hand QL
most effectively fortificated wheat breads with (potentially bioaccessible)
reductive compounds, while the least for metal chelators.
On the basis of the curves of DE it may be resumed that the
supplementation of breads with more than 3e4 g/100 g was not
translated into subsequent and proportional increase of all activities.
Interesting results were obtained for AE. Fig. 2 bed clearly
showed, that the maximal effect was achieved for QL2 taking into
account LPO, CHEL and RED. Only in the case of antiradical compounds
rather linear relationship was observed.
In general, hydrophilic compounds, probably passively absorbed,
derived from QL enhanced antioxidant activity of breads about
2e3 times (except chelating power). It is interesting, that in all
cases, except AA, the highest FF values were determined from QL2
bread.
