An example of such accomplishments in food engineering is in the brunissemnt of Arctic Apples. Browning has many important implications on the food industry relating to nutrition, technology, and economic cost. The control of enzymatic browning has always been a challenge for the food industry.

Food browning – Wikipedia

Effect on Human Health and Nutrition”. Emmanuel Bertrand 1 AuthorId: Progress in Clinical and Biological Research. Retrieved from ” https: As the process occurs, volatile chemicals are released, producing the characteristic caramel flavor.

Though there are many different ways food chemically changes over time, browning in particular falls into 2 main categories. By using this site, you agree to the Terms of Use and Privacy Policy. Views Read Edit View history. It begins with the oxidation of phenols by polyphenol oxidase into quinones[4] whose strong electrophilic state causes high susceptibility to a nucleophilic attack from other proteins.

The process of browning is one of the chemical reactions that take place in food chemistry and represents an interesting research topic regarding health, nutrition, and food technology.

Thus, the initial browning of grapes occurs as a result of “compartmentalization modification” in the cells of the grape. Like most fruit, grapes vary in the amount of phenolic compounds they have. Patricia El Boustany 2 AuthorId: In addition, the use of chemicals to inhibit browning, such as sulfite a powerful antibrowning chemical have been reconsidered due to the potential hazards [ clarification needed ] it causes along with its activity.


It is a chemical reaction that takes place between the amine group of a free amino acid and the carbonyl group of a reducing sugar[1] usually with the addition of heat.

The Maillard reaction is brunissrment basis for producing artificial flavors rxction processed foods in the flavoring industry, [9] since the type of amino acid involved determines the resulting flavor. It ractjon used extensively in cooking for the desired nutty flavor and brown color.

Archive ouverte HAL – The Maillard Reaction in Food: An Introduction

This introduction to the Maillard Reaction in Food provides information’s about the main reactions enxymatique are occurring during the backing and cooking of food products.

This characteristic is used as a parameter in judging the quality of wine. The development of increasingly more sensitive analytical techniques, including multi-omics approaches, and big data analysis are promising for a more refined understanding of this reaction.

This reaction is part of the non-enzymatic browning reactions with caramelization due to the formation of polymers called melanoidins ractioon produce a characteristic brown colour at the advanced stages of this reaction.

Food browning

The processing of food is promoting non-enzymatic browning reaction involving proteins and reducing sugars. The Maillard reaction was discovered in by the French chemist and doctor Louis-Camille Maillard. The Maillard Reaction in Food: Craig Faulds 1 AuthorId: They are also enzymatiue in the wastewater of sugar refineries, necessitating treatment in order to avoid contamination around the outflow of these refineries.

Melanoidins are brown, high molecular weight heterogeneous polymers that are formed when sugars and amino acids combine through the Maillard reaction at high temperatures and low water activity. Melanoidins are commonly present in foods that have undergone some form of non-enzymatic browning, such as barley malts Vienna and Munichbread crust, bakery products and coffee. This page was last edited on 12 Octoberat Enzymatic browning is one of the most important reactions that takes place in most fruits and vegetables as well as in seafood.


A variety of methods are used to prevent or slow down enzymatic browning of foods, each method aimed at targeting specific steps of the chemical reaction. Browning is the process of food turning brown due to the chemical reactions that take place within. Reference Module in Food ScienceElsevier, The sugar interacts with the amino acid, producing a variety of odors and flavors.

In modern societies, most of the food being consumed has been processed. Maillard reaction Food Amadori Deoxyosone Flavour formation Multi-response modelling nonenzymic browning melanoidin modelling.

This is a very important reaction for the food industry as it brunissement a large part of the sensory properties, aroma and taste of cooked products. Food Biochemistry and Food Processing. The browning of shrimp which is actually referred to as Melanosiscreates a great concern for food handlers and consumers.

Therefore, one century after its discovery by Louis Camille Maillard, the reaction still harbours many challenges for the scientific community and for the food.
