Acrylamide, a compound identified as a probable carcinogen, is generated during the sterilization phase employed during the processing of Californian-style green ripe olives. It is possible to reduce the content of this toxic compound by applying different strategies during the processing of green ripe olives.
Acrylamide is formed in two types of table olives where heat sterilization is applied, namely, in California-style black ripe olives and, to a lesser extent, in California-style green ripe olives.
While naturally ripened black olives contain little acrylamide (the maximum concentration was 57 µg/kg), the maximum value of blackened olives was as high as 850 µg/kg.
The major food sources of acrylamide are French fries and potato chips; crackers, bread, and cookies; breakfast cereals; canned black olives; prune juice; and coffee.
The highest acrylamide levels were observed with fried potatoes at 16 h in peanut oil, closely followed by canola oil at 16 h and 28 h or extra virgin olive oil at 24 h.
Acrylamide concentrations of more than 13,000 μg/kg were found for olives with water activities (aw) of 0.8 that still looked appealing for human consumption. Results from table olives and domestic cooking with palatable olives were found to significantly add to the total acrylamide intake, for some Danish consumers.

Drinking more water, a lot more water for some of us, will probably be the most important thing you can do to get rid of Acrylamide. However, make sure you are drinking pure water; otherwise you may inadvertently increase your exposure. Taking herbs to improve kidney and liver detoxification may be helpful.
Acrylamide forming substances (e.g., asparagine and reducing sugars) should be washed away from the surface of the potatoes and vegetables after they are cut by soaking them in water. Soaking them in water will reduce formation of acrylamide during frying.
The bad news about acrylamide is that prolonged exposure of high concentrations can damage the human nervous system and even cause cancer (although no human studies have been conducted).
No reported data of naturally occurring formaldehyde were found for pomegranate, pomelo fruit, pineapple, ripe papaya, sapodilla, guava, olive, amla, bangi fruit, green papaya, plantain and lemon; therefore, the experimental results provide the baseline data for the above food items.
However, the amount of acrylamide in your average brewed coffee is 0.45 micrograms, according to a widely cited 2013 Swedish study. Compare this to the 39-82 micrograms of acrylamide that you'll find in your average serving of fast-food french fries, and that cup of coffee is looking less carcinogenic by the minute.
Acrylamide is a process contaminant formed in bread and other baked products during baking. It forms because of a reaction between reducing sugars and the amino acid asparagine via the Maillard reaction.
Greek olives are rich in vitamins, minerals and phenolic compounds that prevent many chronic diseases. Its fruits and oil, contain a healthy amount of calories, fat and carbohydrates. This little fruit is rich in vitamin B6 which contribute to the proper function of the nervous system and boost the metabolism.
Acrylamide is found mainly in foods made from plants, such as potato products, grain products, or coffee. Acrylamide does not form, or forms at lower levels, in dairy, meat, and fish products. Generally, acrylamide is more likely to accumulate when cooking is done for longer periods or at higher temperatures.
Once in your body, acrylamide enters your body fluids. Acrylamide and its breakdown products leave your body mostly through urine; small amounts may leave through feces, exhaled air, and breast milk.
In most cases, the symptoms and signs of acrylamide exposure have been reversible, with full resolution after 2–12 months of exposure withdrawal, although some symptoms can persist for several years [5].
The formation of acrylamide in both banana varieties was enhanced with an increase in both reducing sugars (glucose and fructose). This research demonstrated that the formation of acrylamide was strongly dependent on the concentration of, both glucose and fructose.
Breakfast cereals – cornflakes and all-bran flakes are the worst offenders, while porridge oats contain no acrylamide at all.
The U.S. Food and Drug Administration monitors acrylamide levels in certain foods, and amounts in peanuts and peanut products are low or undetectable. If present, acrylamide naturally forms when peanuts are roasted; it is not added to peanut butter by manufacturers.
Other scientific studies show that the exposure to ACR induces inflammatory responses in the cerebral cortex through increased expression of mRNA and increased pro-inflammatory cytokine proteins. In addition, ACR induced microglia activation, as indicated by the increased expression of its markers.
Cocoa and its derivatives often have lower levels of acrylamide than potato chips, baked or fried products, and coffee; hence, the reliable determination of acrylamide concentrations at low levels has become an analytical challenge.
Acrylamide content levels of between ≤ 30 and 700 µg kg−1 were determined in cocoa masses from 11 different places of origin. The mean content levels of the 23 examined chocolate samples came to 139 µg kg−1 in the dark chocolates (N = 18) and 67 µg kg−1 in the milk chocolates (N = 5), respectively [16].
