Therefore, there is a need to understand the different types of MRPs and their positive or negative health effects. While foods are processed or cooked at high temperature, a chemical reaction occurs between amino acids and reducing sugars which generate different flavours and brown colour Figure 1.

Acrylamide formation mostly occurs in the outer crust than in the inner crust of bread, while only trace amount appears in the crumb [].

MRP formation affects protein and mineral bioavailability greatly.

April 16, ; Accepted date: International Journal of Food Science. It has been reactuon that people consuming high amount of processed meat, pizza, or snacks develop insulin resistance and metabolic syndrome compared to people having high intake of vegetables and low processed food [ 7 ].

Ultra high temperature UHT treatment or conventional sterilization process is often used to process milk for improving quality and safety. Antioxidants present in the rosemary extracts, bamboo leaves and green tea extract [] could effectively reduce acrylamide presence in different heated foods.

The single monomer form of acrylamide, is recently discovered to be present in food, which is toxic to the nervous system. This may provide useful insights for those related to food processing facilities.

Acrylamide from Maillard reaction products.

Significant efforts have been undertaken in order to develop appropriate strategies that reduce acrylamide in foods. Guidelines Upcoming Special Issues. In another study, beef steak and hamburger rwaction were processed by pan-frying, oven-broiled, and grilled or barbecued to four levels of doneness rare, medium, well cooked, or very well cooked [ 41 ].

Climatic condition such as harvest year has a significant impact on asparagine and reducing sugars in potatoes. When foods are being processed or cooked at high temperature, chemical reaction between amino acids and reducing sugars leads to the formation of Maillard reaction products MRPs.

Acrylamide from Maillard reaction products.

In the early stages, lactose in milk blocks the amino group of lysine to form the Amadori product called lactulosyllysine which changes the protein bioavailability [ 13 ]. Blanching is an important unit operation in the prediction of French fries production. The major pathway leading for acrylamide formation in foods is a part acrrylamide the Maillard reaction with free amino chdmistry asparagine and reducing sugars mainly glucose and fructose [ 59 – 66 ] Figure 2.

Acrylamide is not a substance that is added to food, but it is formed in food during heat processing. Such antioxidant activity of the MRPs comes from the high molecular weight brown compounds that are formed in the advanced stages of the reaction [ 54 ].

Acrylamide primarily found in plant based foods; heat treated starchy foods such as potato, cereal and bakery products contains high levels of acrylamide [ 61315 – 19 ]. Baking at high relative humidity proved to be effective for reducing acrylamide in bakery products [].

Nevertheless, the additives should not alter the quality and consumer acceptability of food products. Can’t read the image? Abstract Maillard reaction produces flavour ;roducts aroma during cooking process; and it is used almost everywhere from the baking industry to our day to day life to make food tasty. Wonder there must be many high starch low protein raw materials used in our day-to-day food consumption, particularly those fried.

Asparagine, is the free amino acid present in potatoes in high level Soybean is widely used as flours, grits, flakes, isolates, mailalrd, and textured soya proteins and also as cooking oil. Investigations on the effect of antioxidant type and concentration and model system matrix on acrylamide formation in model Maillard reaction systems. To date, there is no permissible limits have been set worldwide for acrylamide consumption in diet.

Prolonged fermentation time at least an hour was found to be suitable for acrylamide reduction in bread and fried potato products [ – ]. This study concluded that an extremely hot summer will result in lower acrylamide generation. The basic formation routes of acrylamide in foods in shown in Figure 1.

Acrylamide in Food Products: A Review

Recently, Hong and colleagues rection shown that, under the appropriate conditions, Maillard reaction can effectively improve the ACE inhibitory activity of casein hydrolysate [ 61 ]. The authors declare that there is no conflict of interests regarding the publication of this paper. To reduce the amount of acrylamide, asparaginase has been successfully used in laboratory for potatoes and cereals [ 6970 ].
