  Acrylamide: Putting the Current Findings into Perspective
Acrylamide is a compound that is not added to foods but that forms naturally from a reaction of sugars with some specific amino acids found during certain types of heat processing and cooking.
Acrylamide has been present at some level ever since we began cooking, but it was first identified in food in April 2002, when a group of Swedish scientists presented research that detected trace levels of the compound in some baked and fried foods.
Prior to the Swedish study, food was not analyzed for acrylamide because it was not used as an ingredient, nor was it known to be a component of food.

Acrylamide was accidentally discovered in foods in April 2002 by scientists in Sweden when they found large amounts of the chemical in starchy foods, such as potato chips, French fries, and bread.
Acrylamide in fried or baked goods is produced by the reaction between asparagine and reducing sugars (fructose, glucose, etc.) or reactive carbonyls.
In addition, the acrylamide monomer is a potent neurotoxin, causing the disassembly or rearrangement of intermediate filaments.

 Acrylamide (PIM 652)
Acrylamide intoxication is a clinical diagnosis and should be strongly suspected whenever truncal ataxia with peripheral neuropathy is detected in an acrylamide-exposed worker.
Acrylamide, a vinyl monomer, is formed from the hydration of acrylonitrile by sulfuric acid monohydrate at 90 to 100°C. From the resulting sulfate solution, acrylamide is extracted by neutralization with ammonia and subsequent cooling to isolate the crystalline monomer.
Acrylamide is well absorbed via the skin and the majority of cases of poisoning have been ascribed to repetitive dermal and inhalational exposure in workers handling the monomer.

 ACRYLAMIDE - (Organic Method #21)
There is little published data on the collection of acrylamide, but manufacturers have used a variety of methods due to the possibility of acrylamide being present as a vapor or aerosol.
This was determined by spiking a known amount of acrylamide on a glass wool plug inside a glass tube (both parts silanized), and placing the glass tube ahead of the plastic cassette in the sampling train.
It was not possible to generate a controlled test atmosphere of acrylamide vapors and instrument limitations prevented the generation of an aerosol of acrylamide, so the stability samples were prepared by liquid injection onto the "A" portion of silica gel tubes.

 FDA Urged to Limit Acrylamide in Food ~ Newsroom ~ News from CSPI
CSPI told the FDA that the median level of acrylamide observed in a category of food—77 ppb in the case of frozen French fries—should be set as an interim acceptable level.
Because a flocculant made from acrylamide is sometimes used in the treatment of drinking water EPA requires water suppliers to limit acrylamide to less than 0.5 ppb.
In its petition, CSPI estimated that acrylamide in foods may account for roughly several thousand cancers per year in the U.S., although the amount could be higher or lower depending on the difference in acrylamide’s potency between animals and humans.

 Acrylamide In Cooked Foods: The Glyphosate Connection
Acrylamide is a building block for the polymer, polyacrylamide, a material well-known in molecular biology laboratories as a gel matrix for resolving DNA fragments in sequence analysis and identifying proteins, both under electric fields.
Experiments showed that heat and light contribute to the release of acrylamide from polyacrylamide, and glyphosate was found to influence the solubility of polyacrylamide, so care was advised in mixing the two.
The evidence seems compelling, therefore, that acrylamide is being released from polyacrylamide in the environment, one of the main sources of which is in glyphosate herbicide formulations.

 Acrylamide and Food
Acrylamide is a chemical that forms in certain foods, particularly plant-based foods that are rich in carbohydrates and low in protein, during processing or cooking at high temperatures.
Because acrylamide is known to cause cancer in animals, further research on the effects of exposure to acrylamide is needed before the risks of acrylamide exposure from food can be fully understood.
Acrylamide was not found in boiled potatoes because the temperature during boiling is not high enough to cause acrylamide to be formed.

The FDA's draft action plan for acrylamide in food was presented in September 2002 at the first of a series of public meetings held to get feedback and to provide updates on FDA activities related to acrylamide.
Acrylamide was not found in uncooked or boiled food--studies indicate that it appears to form during certain high-temperature (greater than 250 F) cooking processes, such as frying and baking, and that levels of acrylamide increase with heating time.
Acrylamide levels in 39 samples of potato chips ranged from less than 1.4 micrograms to 100 micrograms per ounce, according to a group of international food safety experts who met in June 2002 in Geneva to discuss the public health impact of acrylamide in foods.

Indeed, he notes, the structure of the amino acid asparagine resembles acrylamide, and asparagine is potatoes' primary unbound amino acid.
Acrylamide formation peaked at 175°C. Even then, he notes, "the yield was low—a little under 1 percent" of the final mix.
Nestlé's findings challenge the notion of any "quick fix" for acrylamide in foods, says Michael Pariza of the University of Wisconsin—Madison, "because we're not going to get rid of amino acids or sugars." He adds, however, that his group is pursuing "some pretty good leads" toward short-circuiting acrylamide's formation from those ingredients.
