So what’s the problem?
This is - at this addition level of the waxy barley flour, there is enough reduction in the amylose content of the the total starch that there isn’t enough of a retrograded amylose network to fully support the weight of the bread. You can see in this photo of the base of the bread where it has begun to collapse over the rods of the cooling rack. Still, on the borderline here – enough to keep it together.
Here’s the good bit: This bread has SUCH a soft and tender crumb, and it will stay fresh [it won't get too firm] for quite a long time compared to the same made with all normal starch, instead of the 33% of amylose-free waxy starch used here from the waxy barley Meresse.
The other good thing[s] are the dietary fiber – both from the barley flour itself and the added 10% on flour weight of sustagrain (Con Agra) very high beta glucan barely flakes. You can see them in the crumb.
