What is the difference between caramelization and maillard reaction

How is white sugar transformed into this brown delight? The sugar molecules break down and new flavor, color, and aroma compounds are formed. Caramelization accounts for the change in smell, taste, and look between normal white sugar and caramel.

Now, the question: what is the difference between the Maillard reaction and caramelization? The Maillard reaction takes place only when both protein and carbohydrates sugar are present. Caramelization is exclusively carbohydrate sugar only. Vegetables contain little or no protein, so technically they caramelize. Stay tuned for an experiment testing the effect of increased caramelization on the taste of caramel!

Enzymatic and Non-enzymatic browning of foods. The quinones can then polymerize to form melanins, which cause the brown pigments Enzymatic browning of fruits and vegetables is usually not desirable and creates heavy economic losses for growers.

It is a pyrolytic reaction. In addition to that, it forms three forms of polymers that are responsible for the brown color of food; caramelans, Caramelens and Caramelins. The below infographic presents more details on the difference between Maillard reaction and caramelization in tabular form. The difference between Maillard reaction and caramelization is that the Maillard reaction is non-pyrolytic whereas the caramelization is pyrolytic. This means, caramelization involves the thermal decomposition of materials in food sugar , while Maillard reaction does not involve any thermal decomposition; it occurs via a chemical reaction between amino acids and reducing sugars in food.

Soak the slices in salt water. Sprinkle with ascorbic acid powder. Wrap a rubber band around a sliced apple put back together. How can we prevent enzymatic browning? Cooks often put cut apples or potatoes in a water bath until they are ready to be cooked. The water reduces contact with oxygen and prevents enzymatic browning.

Cooking fruits or vegetables inactivates destroys the PPO enzyme, and enzymatic browning will no longer occur. Refrigeration can slow enzymatic browning.

How does blanching prevent browning? Warm or hot water will not prevent discoloring. Blanching: This is the process of a short heat treatment to the fruit or vegetable in order to destroy or inactivate enzymes.

Blanching softens the texture, brightens the color, and has little effect on the nutrient content and flavor of the fruit or vegetable. What factors affect enzymatic browning? The most important factors that determine the rate of enzymatic browning of vegetables and fruits are the concentration of both active PPO and phenolic compounds present, the pH, the temperature and the oxygen availability of the tissue.
