The Chemistry of Eggs & Egg Shells

The Chemistry of Eggs & Eggshells 2019

As the chemistry of chocolate is a topic that’s been pretty much exhausted on the site (see here, here, here, here, and here), for the Easter weekend we’re instead homing in on the ‘egg’ side of Easter Eggs. For such a simple staple of the kitchen, the chemistry of eggs is surprisingly complex. Here we take a brief look at their composition, and also at some chemistry tips that can help with cooking them!

There’s one chemical reaction that, whether you have an interest in chemistry or not, we all carry out on a regular, maybe even daily, basis. That reaction? The Maillard Reaction. This is a process that takes place whenever you cook a range of foods – it’s responsible for the flavours in cooked meat, fried onions, roasted coffee, and toasted bread.

The main stages, and some of the different classes of products, are summarised in this graphic.

If you’ve ever tried your hand at jam-making, you’ll know that it’s something of a tricky process. A number of factors need to be just right to achieve a perfectly set jam – and chemistry can help explain why. There are three key chemical entities that go into jam-making: sugar, pectin, and acids. Here, we’ll look at each in turn, and how they help jam achieve its eventual consistency.
