Introduction
UNIFOAM AZ-E is food
grade Azodicarbonamide FCC synthesized, from the synthesis
precursors until the product final, under ISO-9002 Norms
(SGS Yarkey ICS-UK).
Function
UNIFOAM AZ-E is a quick
action oxidizer that acts on the sulfhydryl groups of the
gluten forming disulfur bridges. This way it conditions
and reinforces the structure of the doughs made with
flours of poor content of gluten. In the Fig. 1 are shown
the outline of reaction of the UNIFOAM AZ-E.

Uses
UNIFOAM AZ-E is commonly used as flour improver. Doughs
carried out with flours treated with UNIFOAM AZ-E possess
a more cohesive structure, they tolerate better
absorption of water and this is finally translated in a
better texture and crumb volume. UNIFOAM AZ-E is not
bleach and it doesn't destroy vitamins that the flour
has. Therefore the UNIFOAM AZ-E is ideal to replace other
quick action aditives that are less acceptable as
alimentary preservatives. UNIFOAM AZ-E doesn't react with
dry flour. Neither deterioration is observed during the
storage with flour. UNIFOAM AZ-E acts in quick form when
entering the flour in contact with the water during the
kneading.
