reduces the formation of acrylamide in foods. Acrylamide is categorized as a Group 2A carcinogen
by the World Health Organization, and is found in foods such as bread, cookies, crackers,
baby food, breakfast cereal, French fries, and potato chips.

Franco. (2010). "Acrylamide formation and reduction in fried potatoes." Processing
Effects on Safety and Quality of Food, pp. 231-252.
Several
studies have focused on the acrylamide levels in fried potato products. Some research has
indicated that the levels are related to the Maillard reaction of the product and could
also have to do with the "reaction between amino acids and reducing sugars."
Other factors that may affect the acrylamide level are believed to be the potato variety
and field size, processing conditions of the potato including "pretreatments,
temperatures, and times of frying, type of frying and postfrying conditions" (p.
233). Research indicates that acrylamide is formed "mainly due to the reaction of
asparagine and reducing sugars" (p. 233). While this reaction is believed to cause
the formation of acrylamide, there is also a correlation to the cooking process used and
the temperature of that process or specifically the "thermal input" used in the
processing of the product that increases the acrylamide levels found in the products. Two
diagrams on p. 235 detail the possible ways that acrylamide is formed. One theory is that
acrylamide is produced from the oils present in food while the second theory is that
formation of acrylamide occurs from the "the nitrogen-containing compounds already
present in the food."

Two new ingredients are being
promoted that "are designed to keep acrylamide from developing in food
products." The way the ingredients work is by converting "asparagine, a
precursor of acrylamide, into aspartate, another naturally occurring amino acid. The two
products are Acrylaway from Novozymes and PreventASe from DSM, both ingredients are
enzyme-based. The safety and use of the ingredients are still being considered by the Food
and Drug Administration.. Perspectives on acrylamide are provided by Gary Johnson, global
marketing manager, Novozymes North America Inc., Ruth Donners, business development

Today, California is expected to
propose that warning labels be required on foods that contain significant levels of
acrylamide. Acrylamide is a chemical known to
cause cancer in animals. This chemical was
recently found in snack chips, French fries, cereals, and other fried or baked starchy
foods. California is acting under a 1986 law,
Proposition 65, which requires it to publicly list chemicals that cause cancer, birth
defects, and other health problems. If
accepted, California would be the only state to require the label. Companies are having a problem with this because
they say it would be difficult to label food products going to California and not label
food products going elsewhere. The Food and
Drug Administration and the World Health Organization have acknowledged what acrylamide
does but does not tell consumers to change their eating habits before they do more
research on acrylamide and its effects on humans. The
organizations also urge California to hold off on labeling until the two-year research can
be completed.

In the media, it is easy to find articles,
reports, and information on how carbohydrates are to blame for American's obesity crisis. The U.S. food pyramid guide is now being
challenged for its recommendation of 6 to 11 servings a day for Americans. High protein diets are one reason to blame because
they claim that carbohydrates are bad. Little
information is available to the public that says differently. Some objection to the USDA Food Guide Pyramid
comes from information of the Glycemic Index. The
article includes acrylamide and trans fats, two more issues that are in the spotlight
along with carbohydrates. The grain-based
food industry is responding to attacks that carbohydrates are bad for people. They have yet to give a resound response to the
public. What is needed is a third-party
nutritionist to challenge the misinformation about carbohydrates.

Swedish scientists found high concentrations
of acrylamide in bread, chips, and French fries last year.
But with a new study, they have not found any connection between the dietary intake
of acrylamide and cancer in humans. The study
is not definitive in part because it lacks comprehensive data on acrylamide in various
foods. The study conducted could also have
been too small.

Up The Heat On Acrylamide. (2003) FDA
Consumer (37) 1:10-11.
Acrylamide is a white and odorless chemical
that is found naturally as a by-product in cooked foods.
Scientists have found that acrylamide does cause cancer in laboratory rats. They also know that if a person comes into contact
with a huge amount of acrylamide that it can cause nerve damage. No one knows if the amounts of acrylamide in foods
will cause harm or cancer to humans. The FDA
is still stressing the importance of having a traditional well-balanced diet. They also advise consumers to not cook food
excessively to reduce the amount. They do
reinforce that is more important to fully cook the food to reduce pathogens. There is cooperative research at this time into
studying the effects of acrylamide in humans.
Coffee and Acrylamide.

Coffee was found to have significant levels
of acrylamide, a carcinogen. Swedish
researchers from the state Food Control Authorities in Uppsala found these results. If a person were to drink a liter of coffee a day,
they would raise their acrylamide intake by 100%. A
liter of coffee has 20 micrograms of acrylamide. This
research confirmed earlier results in Switzerland and Germany.

The author discusses what we currently know
about acrylamide. So far, research has not
found acrylamide in uncooked foods, only in foods that are baked, fried, or roasted. Scientists know that large amounts of acrylamide
can cause cancer in lab rats. The amount of
acrylamide in foods is still really low compared to the dosages that were used in lab
rats. The Center for Consumer Freedom (CCF)
issued its own brief to the FDA estimating that there are 8,900 acrylamide-related cancer
cases. More information on the briefing can

smokers had a higher level of acrylamide. Nonsmokers
still had levels of acrylamide but not as high as smokers.
For the nonsmokers, the level of acrylamide is probably due to dietary
uptake. The publisher of the International

A study was reported in the June 18, 2003
issues of the Journal of the National Cancer Institute that suggests in studies
done, acrylamide influences its mutagenicity on DNA by forming adducts and starting
genetic mutations. DNA adducts have the
ability to cause problems with the DNA replication process, which in theory can lead to
tumor formation.
Joy, David. Three
Big Rules To Take Effect This Year. (2003)
Food Processing (64) 4:28, 30.
The Federal Drug Administration will be
putting into effect this year three new rules that will affect food. They include the trans fat labeling rule, food
processing facility registration rule, and a rule that requires prior notification of food
imported into the U.S. None of these rules
originated from the FDA. The Public Health Security and Bioterrorism Preparedness and
Response Act of 2002 mandated the import notification rule and facility registration rule. The trans fat rule started in part by a petition
filed with the Center for Science in the Public Interest.
Not only are food manufacturers having to worry about these new rules, they are
also faced with growing interest in allergens and acrylamide. Acrylamide is believed to be a carcinogenic that
appears naturally in certain starchy foods that are cooked at high temperatures. Acrylamide and allergens will be getting more
research to ensure that our food is safe.

Possible Cancer Causer Appears in Nutritious Food As Well As In
Fast Food. (2003) Medical Letter on
the CDC & FDA 3/23/2003:11-12.
U.S. government scientists say that
acrylamide occurs both in fast foods and in nutritious foods. Acrylamide could be a possible cancer causing
substance that occurs naturally in high-carbohydrate foods that are cooked at high
temperatures. The Food and Drug
Administration reports that foods that have lower levels of acrylamide are eaten more
often that increases overall exposure. Foods
such as milk, frozen vegetables, and meat contain no acrylamide. The following foods contain acrylamide: toast and
soft bread at 2.2, breakfast cereal at 7.3 mcg, cookies at 6.6 mcg, and coffee at 2 mcg. Some popular foods, like pizza, have yet to
measured for acrylamide levels.
Raloff, J. Exonerated? (2003) Science News (163) 6:84-85.
The Swedish did an analysis that tried to
play down the likelihood that people could get cancer from foods that have acrylamide
naturally. Acrylamide is a building block for
plastic and an animal carcinogen. Last year,
researchers found that it forms during high-temperature cooking. Examples include fried and baked foods like
potatoes, breads, and starchy foods. After a
study, the researchers concluded that acrylamide in the human diet must be
effectively detoxified.
Researchers Dispute Link Between Acrylamide and Some Types of
Cancers. (2003) Cancer Weekly

A study shows through preliminary research
that there is no link between acrylamide and an increased risk in some types of cancer. There was a follow up article in the British
Journal of Cancer (2003;88(2)) from researchers in Sweden and the U.S. found these
results. Experts still caution that the
follow up study was too small.

Sweden released research reports that showed
findings of acrylamide in normally cooked foods. In
1994, the International Agency for Research on Cancer (IARC) reported acrylamide as a
human carcinogen. Regulatory agencies
confirmed the Swedish research and reported that they could give no advice on how to avoid
acrylamide in foods or what amount was safe for human consumption.

The authors describe a simplified analytical
method to determine how much acrylamide is in food. They
determined that routine analysis was not attainable from previously published procedures. The method that they used had a preliminary
sample defatting step that was followed by extraction with methanol and concentration. GC/MS evaluated the acrylamide concentration
without derivatization.
U.S. Agency Finds Highly Variable Levels of Worrisome Chemical
in Foods. (2003) Medical Letter on
the CDC & FDA 1/5/2003:8
Federal research that was released December
4, 2002 showed that the level of acrylamide might depend on what length of time the food
is cooked. The U.S. Food and Drug
Administration is doing preliminary testing that is showing how American food compares to
other countries in terms of the level of acrylamide found.
Through their research the FDA has also found that by testing the same
food, they find different levels of acrylamide. The
FDA has hired a panel of experts to help them find a way to lower the amount of acrylamide
in foods.

Action Plan for Acrylamide. (2002) Food
Processing (63) 11:24, 26.
Sweden and other countries have
confirmed through research that acrylamide forms through high-temperature cooking of
certain starchy foods. Before this discovery,
chemists were the only ones who really knew of this carcinogen. Chemists knew acrylamide as a chemical
intermediate in the production of polyacrylamides, dyes and copolymers for contact lenses. Acrylamide has always been a chemical that has
been severely limited in the water and food supply by laws and regulations. Now, it is found in cooked starchy foods and
raises health concerns. What question has to
be answered now is if acrylamide is as dangerous as what was previous thought. What is needed to answer this question is a
careful, scientific research study. The Food
and Drug Administration has proposed a draft for an action plan for acrylamide, which
includes more research of the toxicology of acrylamide.
