For You, the Consumer
Some of the many products
in your shopping cart that
are derived from ARS
research-items ranging from
lactose-free milk to shoe
Abundant, affordable, safe, vast varietyit's the
American way when it comes to shopping. What isn't found on any store
shelf is an Agricultural Research
Service brand name. But many products that people use every day
could justifiably carry the stamp "Courtesy of ARS Research."
Pharmaceuticals, cosmetics, roach and termite controls,
leather, shampoos, and processed foods, not to mention a proverbial
cornucopia of fruits, vegetables, berries, meats, and nuts, all come
to a store near you by way of ARS laboratories. Of course, there are
essential stops along the way for technology transfer to the companies
that turn out the actual products.
But without the work that ARS invests in researchoften
long-term, high-risk researchthere are whole industries of products
that might never have gotten off the ground. Some products make it tastier
to balance your diet. Some keep you warm and fashionable. Some improve
recreation and athletics, and others keep you safe and healthy.
All these products make
use of soybeans. When
ARS research develops
new uses for agricultural
commodities, it benefits
both consumers and farmers.
One product in that last category of safety and health
to which consumers now have access as a result of ARS research is irradiated
hamburger free of Escherichia coli O157:H7, bacteria that can
cause serious, even life-threatening illness. Ground beef is especially
vulnerable because more than just the surface of the meat may potentially
have been exposed to bacterial contamination.
The term "irradiated" refers to treatment with
ionizing radiation from gamma rays produced by cobalt and cesium atoms,
machine-produced X-rays, or electron beams. Treated meat in no way becomes
Omaha Steaks, for example, began offering irradiated hamburger
patties and ground beef in November 2000. Today, all the 6.5 million
pounds of ground beef they sell each year in their retail and bulk food
service operations is irradiated.
Irradiated ground beef from
Bruce Simon, president of Omaha Steaks, feels strongly
that, with irradiation, research has developed a way to provide consumers
with an extra measure of food safety for ground beef. "We know
we were among the first beef companies to make use of irradiation. Whenever
we can add another safeguard to make sure that there is less possibility
that anyone, especially a child, could be exposed to E. coli,
it's a step we just have to take," Simon explains.
Consumers won't see ARS' name where it says "Treated
by Irradiation" on Omaha Steaks' hamburger packaging. But much
of the research to prove irradiation an effective and safe method to
sanitize ground beef came from the laboratory headed by ARS microbiologist
Donald W. Thayer.
"When you look at the docket that was submitted to
the Food and Drug Administration and the Food Safety and Inspection
Service to get approval for irradiation of red meat, many of the papers
they cite are from ARS," Thayer says. Final approval for irradiation
treatment of meat came in February 2000.
Sixty years ago, orange
juice came either freshly
squeezed in season or canned
and tasting like the can.
But in 1948, ARS scientists
collaborated with Florida
Citrus Commission researchers
to perfect a method to produce
a practical, flavorful frozen
concentrate with all its
vitamins and minerals.
Products that protect people from illness are not new
accomplishments for ARS. In 1954, ARS developed N,N-diethyl-meta-toluamide
for the Department of Defense to protect soldiers from disease-carrying
insects. Now best known simply as DEET, it remains the most effective
mosquito repellant available. About 230 products containing DEET are
currently registered with the U.S. Environmental Protection Agency.
World Health Organization statistics report that mosquitoes
spread about 4 million malaria cases, causing about 1 million deaths
globally each year. These insects also spread dengue fever-related illnesses,
which lead to 24,000 deaths annually.
More recently, the spread in the United States of West
Nile virus, also mosquito borne, has focused new attention on DEET.
West Nile virus has been reported in 36 states plus Washington D.C.,
and it is expected to spread to all 50 states.
The Centers for Disease Control and Prevention recommend
that people in affected areas always wear an insect repellant containing
DEET when they go outside during mosquito season as the best protection
against being exposed to West Nile virus.
Insect repellants made from
DEET, an ARS-developed compound.
Some possible concerns about DEET posing a health risk
have been raised. EPA has reviewed the data and determined "normal
use of DEET does not present a health concern." Several changes
have been made in the label directions to ensure DEET is safely applied,
principally to avoid oversaturating skin or clothing and not to spray
Many antibiotics could also bear the ARS stamp. In 1941,
British scientists, overwhelmed by World War II, requested U.S. help
to find a way to produce penicillin in mass quantities. The problem
was given to Andrew J. Moyer and others at the National Center for Agricultural
Utilization Research, then called the Northern Regional Research Center
(NRRC), in Peoria, Illinois.
Work began in July 1941. By November, Moyer had succeeded
in increasing the yield of penicillin by creating a better growth medium
with the addition of corn steep liquor, an inexpensive byproduct of
wet corn milling, and milk sugar. The team's development of deep vat
techniques to grow the mold cultures, called deep fermentation, added
the missing piece of the production puzzle.
Strawberries, blackberries, and
blueberries have all been
improved by ARS research.
Eight days after the bombing of Pearl Harbor, NRRC representatives
met with U.S. drug companies, which agreed to attempt large-scale production
of penicillin using the new methods. The combined work of many researchers,
including ARS scientists, resulted in making penicillin available in
mass quantities by June 6, 1944, just in time to treat Allied soldiers
wounded on D-Day. Infection has always been one of the largest causes
of death in war, more so than direct battle injuries.
Mass-produced penicillin saved many lives during World
War II and continues to do so. And the improved growth media and deep-fermentation
methods and their outgrowths have since been used in development of
many other important antibiotics. In 1987, Moyer became the first federal
government scientist inducted into the National Inventors Hall of Fame.
Filling the Cornucopia
Any time they shop for produce, people are very likely to be buying
a result of ARS research. The agency's successes in breeding new fruit,
vegetable, nut, and berry varieties have had an incredible impact on
what consumers eat. New flavors, extended harvest seasons, increased
growing range, and better shelf life are just a few of the improvements
ARS researchers have made.
Gourmet vegan chocolates made
with Nutrim, an ARS-developed
product that can substitute
for dairy products in baking.
Almost all the blueberries and cranberries in commercial production
were either developed by ARS or bred from ARS varieties. ARS also brought
consumers super-sweet strawberry varieties with longer shelf life. Southern-grown
fresh peaches would probably not be readily available to consumers in
eastern U.S. markets if ARS had not developed improved peach varieties
as well as the Guardian rootstock.
Citrusfresh and processedalso has ARS' fingerprints all
over it. More than 80 percent of the citrus grown in the United States
are rootstock or fruit varieties developed by ARS. When you buy a sweet
red grapefruit, chances are pretty good that it will be a Flame grapefruit
from ARS. Most of the early-season tangerinesabout a $100 million
annual retail productare ARS varieties Sunburst and Fallglo.
Lactose-free milk and
milk products, for people
who cannot digest dairy
Red seedless grapes were all but unknown to the U.S. consumer before
ARS released the Flame variety in 1973. Release of another ARS variety,
Crimson, in 1989 further increased this table grape's popularity. The
two varieties alone, now grown extensively by both domestic and foreign
producers, make up a major portion of today's consumer market.
Sweetpotato varieties released by ARS are the standard, keeping the
price of this crop affordable, the quality high, and the supply steady.
The same can be said for cantaloupe, watermelon, broccoli, nectarines,
plums, lettuce, peppers, onions, carrots...the list of fruits and vegetables
that ARS research has improved is almost endless.
In addition to whole foods like apples and
oranges, ARS has also developed many ingredients that people buy every
day as part of processed foods. On a wide variety of food ingredient
lists appear some form of the words "hydrolyzed oat flour"
or "hydrolyzed oat bran." A lot of that is actually ARS' patented
Oatrim, a calorie- and cholesterol-lowering replacer for shortening
made from enzyme-treated oats and barley.
The beautiful blooms of
crape myrtle are now
common in many U.S. gardens
because of improved cold
tolerance and disease
resistance provided by ARS.
Oatrim has been licensed to several companies, including Quaker Oats,
Inc., which uses Oatrim in foods like some Healthy Choice dinners. Oatrim
production was estimated to be in excess of 20 million pounds in 1999,
resulting in more than $1 billion in retail sales.
Nutrim, another ARS development similar to Oatrim, has recently led
to a new, niche-market consumer product: gourmet vegan chocolate truffles.
Mrs. Mudd's, Inc., of Oceanside, California, worked out a way to make
tasty chocolate truffles with a great mouth feel without any dairy ingredients.
When mixed with water, Nutrim flows like heavy dairy cream or coconut
"It took 2 years to work out the right formula," says company
president Jan Mudd. "But our dark chocolate truffles are certified
organic and completely vegan, so they are the perfect choice for people
who are watching their cholesterol or those who do not eat dairy products."
Xanthan gum, discovered by ARS in the 1960s, is another
food ingredient that appears in a whole host of consumer products. This
natural product comes from fermenting corn sugar with the microorganism
Xanthomonas campestris. Even a partial list of functions provides
insight into why it is a ubiquitous ingredient: it thickens liquids,
provides good cling, provides easy pourability and pumpability; controls
crystallization, increases baking volume, provides temperature stability,
and suspends active ingredients.
Salad dressings, instant soups, chocolate sauces, ice cream, cake mixes,
yogurt, and squeezable chewing gum are just a few of the food products
that make use of xanthan gum. It is also in products like toothpastes,
cosmetics, rust removers, water-based paints, and antidiarrheal medicines.
Green Side Up
ARS is not an acronym you think of in connection with the NFL, PGA,
or even your neighborhood soccer field. But ARS' bermuda grass varieties
are taking over recreation fields and golf courses, especially in the
southern part of the country. Tifsport, developed and released in 1997
by ARS plant geneticist Wayne Hanna in Tifton, Georgia, has a whole
team roster of beneficial traits.
"We managed to breed in all the important traitsexcellent
cold tolerance, uniform dark green color, aggressive establishment,
improved pest tolerance, earlier spring green-up, and an ability to
tolerate frequent lower mowing," Hanna explains. "But most
importantly, Tifsport can stand up to the stress and demands of big-time
sports, to the wear and tear of football and soccer cleats, to the punishment
of baseball spikes, and to constant heavy foot traffic."
Professional sports teams, universities, high schools, and local recreation
departments across the South have installed Tifsport on athletic fields.
Texas A&M recently planted about 97,000 square feet of Tifsport
turf to give the Aggie soccer team a new playing field.
The NFL Tennessee Titans football team installed Tifsport when Adelphia
Coliseum was built. A league-wide player survey in 2001 rated the coliseum
as the fourth best playing surface in the National Football League.
"Tifsport has great leaf texture and good dark green color. But
the best thing is that the grass stands up well to use; it shears rather
than divots so it lasts longer," explains Terry Porch, sports field
manager for the Titans.
Southern golfers not only play on fairways planted with Tifsport; many
also putt on Tifeagle, a triploid bermuda grass variety Hanna released
in 1999. At last count, there are Tifeagle greens in 14 states and 7
countries. Tifeagle can be mowed to one tenth of an inch daily to provide
a smooth, fast putting surface. The previous standard for southern golf
greens, Tif-dwarf, also an ARS development, can only be mowed to three
sixteenths of an inch.
ARS has been responsible for the bermuda grass standards for southern
sports fields, golf courses, commercial landscaping, and home lawns
since grass breeder Glenn Burton started the program in 1952. "Golfers
were playing on sand or at best rough common bermuda grasses before
ARS developed the improved triploid hybrid ones," Hanna says.
Gardeners also benefit from ARS research. Breeding successes like camellias
with better cold tolerance, American elms resistant to Dutch elm disease,
and later flowering magnolias have given landscapers and gardeners important
One ARS advance consumers buy in droves every year are crape myrtles
developed to resist powdery mildew in the South and colder temperature
in the North, making the shrubs one of the country's most popular. "Within
its current hardiness zone rangewhich is now pretty much Baltimore
south because of ARS introductionsthere is hardly a major landscape
project today that doesn't include one or more crape myrtles. ARS changed
the crape myrtle world," says Marc Byers of Byers Wholesale Nurseries
of Huntsville, Alabama.
Byers sells tens of thousands of crape myrtles each year and a significant
percentage are ARS-developed varieties. Natchez, released by ARS in
1978, continues to be the standard by which all other white crape myrtles
are judged. Twenty-four years is a long time for any one woody plant
variety to remain the standard for landscapers, Byers points out.
You may even be wearing ARS research as you read this article. In 1958,
wash-and-wear cotton clothes hit the consumer market. Since the 1950s,
ARS scientists have played key roles in the research to develop durable
press treatments, usually called permanent press, that give cotton and
cotton blends wrinkle resistance. And durable press plays a key role
in the continued popularity of cotton and cotton-blend fabrics.
"Trousers represent the largest single apparel market for cotton
today, and I estimate that when we exclude jeans, more than half of
all mens', boys', and ladies' trousers are made from durable press-treated
fabrics," says Andrew Jordan, director, technical services for
the National Cotton Council. "ARS' work was fundamental to putting
together the technology."
Other ARS research on cotton has reached the consumer in the form of
fiber-reactive dyestuff groups that allow cotton to be dyed more bright
colors and better flame-retardant treatments, including new-on-the-market,
fire-resistant cotton carpet.By J.
