Acrylamide in bread products Methods of formation • Acrylamide is formed via the reaction of asparagine and reducing sugars (both naturally occurring in cereals); in few cases sugar is also added to bread as a minor ingredient • Acrylamide is formed at temperatures °C; low amounts will be formed during normal baking

If you peruse the list you will note that the foods that seem to contain the most acrylamide are those, such as bread and potatoes, that contain carbohydrates. This is because acrylamide is formed when carbohydrate carbons (the black balls in the diagram) combine with the (blue) nitrogen from amino acids in the foods: this occurs when the food is cooked at high temperature (think toaster). In the case of whole wheat bread, dark toast had higher acrylamide levels of 8.9 times (34 ppb in bread increases to 301 ppb in dark toast). However, when produced with AR yeast, dark toast made from the white and whole wheat bread (that contained just 5 ppb prior to toasting) contained only 36 and 67 ppb of acrylamide, respectively, after toasting.

Acrylamide 8 Ways To Reduce This Well-Known Carcinogen.

Acrylamide forms when bread is toasted and the amino acid asparagine reacts with sugars at high heat. CREDIT: MILOS LUZANIN / SHUTTERSTOCK When green coffee beans are roasted (typically at 180° to 240°C for about 15 minutes), more than 1,000 chemical compounds result as different sugars and amino acids combine and break down.

Glycine addition significantly decreased acrylamide depending on the initial levels of asparagine in the dough, and increased the colour intensity of the bread. Abstract Addition of 1% aqueous rosemary extract with Keywords Acrylamide · Wheat bread · Rosemary · approximately 40 mg of gallic acid equivalents or compara- Green tea Xavonoids · Degradation ble addition of rosemary oil or of dried rosemary leaves to wheat dough reduced the content of acrylamide … A modest effect of the peroxides in oxidized oil on acrylamide elimination was observed pointing towards an oxidative induced polymerization of acrylamide. The impact of oxidative processes on acrylamide elimination should not be neglected, since oxidized vegetable oil seems to promote degradation of acrylamide.

acrylamide content in the bread were analysed. The rye bread baking tests were carried out in an industrial bakery. The results of the soil analysis indicated a deficiency of sulphur containing compounds. The usage of enzyme asparaginase in rye bread production caused no significant reduction (p>0.05) of acrylamide content in rye bread.

For example, the scientists  Acrylamide is mainly formed in food by the reaction of asparagine (an amino acid ) potato crisps3, coffee, biscuits4/pastries, bread and rolls/toasted bread. 19 Aug 2008 Bread is among the products that can contain high levels of acrylamide, so this thesis investigated factors affecting acrylamide formation in bread.
