NATURAL ANTI-STALING

Enzymes can help bakers reach extended shelf life and still maintain
softness and resiliency in their breads.

Extending shelf life without synthetic anti-staling
ingredients while maintaining product quality can be
tricky. Antioxidant- and enzyme-based solutions, however, can offer bakers an out in this push against time.

At the molecular level
Staling is caused by a number of variables. Starch retrogradation and water activity lead the way as baked goods
begin to stale. Environmental conditions can either accelerate or delay those processes.
Starch contributes to many desired characteristics
such as mouthfeel, softness and texture. When baked,
the starch in a dough will absorb water, swell and gelatinize. This process is critical for setting structure and
texture. However, once the baked good is out of the
oven, gelatinization slowly begins to reverse. That starch
retrogradation is when the amylopectin in starch granules recrystallizes, causing in turn the firming of a baked
good's crumb structure.
Water activity measures its energy in a formulation and determines the direction of moisture flow. In
bread, this means the water activity between crust and
crumb. Over time, water migrates in a baked good to
where there is none or less of it. This causes crisp crusts
on bread to become tough and chewy or the sugar coating on donuts to melt as the water moves from interior
crumb to the outside. In a variety of baked goods, water
activity can cause a host of other issues.
Rancidity, another tell-tale sign of an aging baked
good, occurs when fat is undergoes oxidation. This results
in bad odors and off-flavors. The process can be accelerated by high temperatures or slowed down by antioxidants,
which interrupt and stabilize the chain reactions occurring at a molecular level when oxidation occurs.

A clean fight
Synthetic antioxidants, crumb softeners, emulsifiers and
artificial preservatives may not be in style today, but
bakers have several options for anti-staling ingredients
that won't turn consumers off. Natural antioxidants, enzymes, ferments and natural mold inhibitors can stave
off staling and rancidity.
"There have been many advancements in this space
in the past 10 years; however, the addition of enzymes
has truly revolutionized the baking industry," said
Emily Guilfoyle, bakery R&D manager, Kemin Food
Technologies. "Anti-staling enzymes have helped manufacturers deliver the perfect eating experience for their
product and enhance quality throughout its shelf life to
deliver the best experience for the end consumer."
