Frosting Migration More Serious than Previously Believed
Frosting migration poses a significant economic risk to America's doughnut purveyors, according
to researchers at Cornell University.
In a study to be published in the April 2003 issue of Science, researchers demonstrate that the
average doughnut can lose up to 50% of it's frosting in under three hours when stored in a vertical
position.
"Although we expected to find a certain amount of degradation, the actual extent to which
coverage was reduced was surprising," said Dr. Duncan d'Eaunotz in a press release this morning.
"Certain factors did appear to reduce slippage, such as the presence of jimmies or shredded coconut.
However, even in these instances, losses of up to 25% were observed under laboratory conditions."
The study has significant implications for the nation's $2.5 billion doughnut industry, which
depends primarily on viscous sugared coatings to differentiate itself from the $10.5 billion dollar
pre-packaged snack industry. "I mean, the frosting on a Hostess cupcake - that's not going
anywhere, even in a zero-gravity environment," said d'Eaunotz. "Traditional circular baked goods
purveyors have worked hard to distinguish their products from the mainstream, primarily through
products which offer increased frosting-to-face transfer."
In recent years, reeling from unexpected declines in market share due to the rise of specialty
coffee houses such as Starbuck's - which often offer their own baked goods - traditional doughnut
bakery chains such as Krispy Kreme have resorted to stacking their products vertically in order to
maximize storage efficiency.
"Vertical storage gave the industry a temporary boost because of the perceived increase in
value," noted economist K. Khreim of Stanford University. "Consumers felt that the boxes looked
fuller with the new arrangement. However, the resulting dissatisfaction with doughnuts half-covered
in a viscous mess has detracted from this initially positive consumer reaction."
Loathe to dispense entirely with the otherwise profitable practice of vertical stacking,
doughnut industry scientists are turning to nanotechnology-based solutions, including netting made
of microfibers to adhere the frosting layer to the doughnut without sacrificing low viscosity, and
combining frosting mixtures with increased iron content and magnetized doughnuts. None of these
solutions is expected to be ready for the consumer market until 2005 at the earliest, however.
"It puts the leading doughnut makers in a difficult position," acknowledged Kriem. "For the
time being, I'm buying my doughnuts one at a time."
