Does Maillard reaction affect nutritional value?
The Maillard Reaction (MR) is a non-enzymatic chemical reaction which results in the linkage between the amino group of amino acids and the carbonyl group of reduced sugars. MRPs presence is known to reduce the nutritional quality of foods, particularly by reducing protein digestibility.
What are Maillard reaction products MRPs and how are they produced?
Heating of food induces the formation of Maillard reaction products (MRPs) caused by the reaction of reducing sugars with proteins or amino acids. Analogous reactions occur in the human body, eventually forming “Advanced Glycation Endproducts” (AGEs).
What are some advantages of the Maillard reaction?
During heat treatment such as frying, roasting, and baking, the Maillard reaction improves food in taste, flavor, and color. When foods are stored however, the reaction often gives unfavorable effects, such as decreased nutritional value and color deterioration.
What stops Maillard reaction?
This can be discouraged by heating at a lower temperature, adding asparaginase, or injecting carbon dioxide. In the cooking process, Maillard reactions can produce hundreds of different flavor compounds depending on the chemical constituents in the food, on the temperature, the cooking time, and the presence of air.
Is Maillard reaction good or bad?
The Maillard Reaction is known to create a carcinogen called Acrylamide. It’s so serious the food standard agency is working to reduce the amount of Acrylamide in our own human food. It is a risk to humans but has been proven to be a more significant risk to our pets.
What is the science behind the Maillard reaction?
The Maillard reaction is a chemical reaction between an amino acid and a reducing sugar, usually requiring the addition of heat. Like caramelization, it is a form of non-enzymatic browning. This reaction is the basis of the flavoring industry, since the type of amino acid determines the resulting flavor.
Is the Maillard reaction reversible?
The first step of the Maillard reaction mechanism. In this step a sugar (in this case glucose) reacts with an amino group (which can be attached to a protein) to form an Amadori compound. The reactions with arrows in both sides indicate that the reaction is reversible.
How can I speed up Maillard reaction?
It is possible to speed up the Maillard reaction by choosing favorable conditions, including adding protein or a reducing sugar, increasing the temperature, using less water (or boiling off water), or increasing the pH. Sometimes, a slower Maillard reaction is desired, especially in industrial food preparation.
