Riley Reveals Successful Tests of Materials Using
Light Filtering Process To Protect Food Products
Rites For George
C. Graves, Moore
Native, Are Held
Light - filtering, protective
packaging materials that can be
of great importance to farmers,
the food industry and the public
were announced this week by E.
G. B. Riley of Southern Pines,
president of Rilecoe Filter Pro
cess, Inc.
The product of years of re
search—in which Mr. Riley work
ed closely with General Dyestuff
Corporation, one of the nation's
leading chemical firms—^the ma
terials include paper, plastics and
textiles, designed to retard spoil
age in all kinds of food, both in
their natural and processed
forms. Extensive laboratory and
field testing has shown the ef
fectiveness of the new materials,
Mr. Riley reports.
Holds Many Patents
A student of ihe effects of light
for many yeeus and the holder of
many United States and foreign
patents in this field, Mr. Riley
has lived in the Sandhills for
about 16 years, following his re
tirement from a successful busi
ness career in New York City. In
addition to his work with light
filtering materials, he is known
for his pre-World War 2 advo
cacy of a stronger U. S. Air Force
and his spearheading of efforts
that resulted in the posthumous
award of the Congressional
Medal of Honor to General Billy
Mitchell, pioneer advocate of mil
itary air strength.

a series of letters to the foreign
ministers and other officials of
the leading nations of the world,
in which he advocated cessation
of testing detonations of nuclear
and thermo-nuclear bombs. In
the letters and in an article writ
ten for The Pilot, Mr. Riley con
tended explosion of these bombs
will destroy those particles in the
upper atmosphere that prevent
deadly cosmic and gamma rays
from reaching the earth.
Wavelengths Filtered
In connection with his food
preservation materials; Mr. Riley
explains: “Certain specific wave
lengths of those which constitute
visible light and certain other
wavelengths in the invisible
spectrum are responsible for the
rapid spoilage that occurs in food,
dairy and other products.
“By developing food packaging
materials which inhibit or filter
out these harmful wavelengths
and permit transmission of those
wavelengths which Nature util
izes to produce plant food (photo
synthesis), the percentage of
spoilage is greatly reduced and
the products retain their flavor
and original condition for a much
longer period of time.”
Hundreds of different dyes
were tested before the exact ones
were produced that would filter
out the harmful rays, that cause
spoilage. The job was complica
ted because a different dye for

coe process, says Mr. Riley, is to
incorporate the dye components
in the raw packaging material,
but finished materials may be
dyed or coated with the light-
filtering dyes.
The Southern Pines man used a
simple illustration from Nature
to explain what his light-filtering
materials accomplish.
“Light emitted by the sun is
responsible for both plant and
animal life,” he says, “but expos
ure to sunlight for extended peri
ods of time results in destruction
of both forms of life. While it is
maturing, a plant or plant pro
duct, such as fruit, is protected
by a skin covering that acts as
a filter to keep out the harmful
wavelengths of light. At maturi
ty, however, the skin or outer
covering loses its protective prop
erties—as when an apple turns
red—and permits the ultra-violet
and ‘harmful’ regional bands of
wavelengths to be transmitted,
resulting in the decomposition of
the plant or plant product.”
In Artificial Light, Too
These same harmful wave
lengths of light are found in the
bright light emitted by fluores
cent and other artificial light
sources which are turned on veg
etables, fruit, meat and many
other food products in markets,
Mr. Riley notes.
Not only does unfiltered light
cause spoilage, he points out, but
the effect of the “harmful” wave
lengths results in Ipss of flavor,
vitamins and proteins. Meat, usu
ally displayed under light un
wrapped or wrapped in non-filter
ing material, changes color in only
a short period of time.
Moreover, says Mr. Riley, it’s
“a most erroneous conclusion”
that any material that is not
transparent prevents the trans
mission of light. Tests have
shown, he says, that even heavy
(80-pound stock) paper pennits
transmission of harmful light. Al
so, food products that have been
stored in total darkness become
supersensitive to light and, on ex
posure to light, a rapid break
down occurs in them.
Food markets could be protect
ed, says Mr. Riley, not only by
packaging the original products
in light-filtering materials, but
the existing lights over food dis
plays could he shielded with a
Rilecoe material Which filters out
the harmful wavelengths.
Would Affect Farmers
Farmers would benefit from
the protective materials because
they cut down spoilage—a pro
cess that would benefit progres
sively the food distributor, the
retailer and the public. Spoilage
in some food products, front farm
to consumption, runs as high as
40 per cent, as shown by reports
of the Department of Agriculture.
Protection could begin in the
field when fruit or vegetables
could be placed immediately on
harvesting in bags or containers
made of light-filtering materials,
he notes.
The local man sums it up like
this; “By proper scientific pack
aging and display illumination,
food processors and stores can
make available food products
possessing all their health-giving
nutrients, retaining their original
flavor and greatly extending
their edible and shelf life.
“In addition, by eliminating or
greatly reducing the spoilage that
is now incurred, retail markets
can pay the producers a higher
price for their products without
increasing the cost to the public.”
Negotiations Now Going On
A fascinating outlook? Anyone
who has gone over with Mr. Riley
the problems and the possible so
lutions — backed by reams of
facts, figures, laboratory reports
and other information—^is bound
to understand his enthusiasm and
his interest.
Negotiations he is now con
ducting with representatives of
the food industry may result in
widespread use of Rilecoe ma-
tGirisls
The public, Mr. Riley believes,
can be educated to accept the
light green color of the filtering
materials, even though people
are now accustomed to colorless
transparent packaging for most
food products.
Mr. Riley thinks that, once the
consumer discovers the benefits
to be derived from the materials
in freshness, flavor, nutrition and
[lower prices, the new material
will be accepted by the buying
public, regardless of color.
“After all,” he points out, “the
color is Nature’s own color of
life-building—photosynthesis, the
secret of plant life and thereby
the fundamental basis of all liv
ing things.”
