Can smart selection of ingredients, packaging, package
instructions and consumers’ choice of microwave ovens
assure that consumers’ microwave validation results
match yours?
NRTE Food Safety Success
NRTE Food Safety Success--Sampling
NRTE Food Safety Success--Sampling
Known microwave hostilities
NRTE Food Safety Success—Comfort Food
Leveraging what microwave ovens do best
NRTE Food Safety Success
Microwave ovens love to steam
NRTE Food Safety Success—Packaging High Tech
NRTE Food Safety Success—Packaging Low Tech
Old
New
Subtle packaging adaptations can transform unsafe to safe
What happens when the bell rings?
How much does standing time help?
Who has a thermometer at a) home b) work c) school?
NRTE Food Safety—Standing Time

Mains voltage varies within bounds set forth
by the American National Standards Institute
(‘ANSI’) in concert with NEMA and EEI

The standards have worked for 125 years, and so does your Microwave.
Right—so what’s the issue?

GMA Validations Neglect Power Factor.
As per the IEC 60705 microwave oven test protocol

AC Power Factor: AC is not DC
What The Power Company Supplies
aka ‘Apparent Power’ or
Voltage * Current
