However, while we did not observe enrichment of a-amylase/
trypsin inhibitors in foam from DL from fermented dough (Section
3.2.1), this does not rule out that they would stabilize foams.
Additionally, PINs were more enriched in foam from DL from
fermented dough than in any other DL sample, while no enrichment
of other proteins was observed (Section 3.2.1). The enrichment
of very surface active PINs may well partially explain the
more pronounced foam formation of DL from defatted fermented dough
