What reactions cause discoloration in milk?

The browning in dairy products, similar to other foods, is attributed to two possible reactions: the caramelization of lactose and a Maillard-type reaction between lactose and milk proteins leading to forma- tion of amino-sugar compounds.

What happens when milk turns yellow?

Cow's milk is naturally yellowish in color due to the presence of beta carotene. Our body converts this beta carotene into Vitamin A when milk is ingested. So it is absolutely safe to take that.

At what temperature does milk caramelize?

CARAMELIZATION AND ITS SIGNIFICANCE. Caramelization is a type of non-amino browning reaction. This process consists of heating sugar slowly to around 170°C.As the carbohydrates are heated, the molecules break down and reform into compounds with a characteristic brown colour and flavour.

What does a Maillard reaction do?

The Maillard reaction creates brown pigments in cooked meat in a very specific way: by rearranging amino acids and certain simple sugars, which then arrange themselves in rings and collections of rings that reflect light in such a way as to give the meat a brown color.

What happens when milk Burns?

Scalded milk is dairy milk that has been heated to 83 °C (181 °F). At this temperature, bacteria are killed, enzymes in the milk are destroyed, and many of the proteins are denatured.
