Ever wondered why your broccoli changes colour when it cooks? Ever wondered why your muffins didn’t work out? Or just curious to know why a recipe works? Then you’re at the right place! Here you can find everything on the science behind food. Food Science explores what happens in food when it’s stored, processed, cooked, eaten, etc.
What is food science?
Food science aims to understand food from a science perspective, not focussed on health & nutrition but instead looking at how food is made & prepared and why it’s done that way. Food science involves studying all sorts of processes involved in food, during harvesting, storage, packaging, preparation and consumption.
Some examples when studying apples:
- An apple turning brown (enzymatic browning)
- An apple turning soft when being cooked (breaking down of cellular structures)
- How to scale up applie pie production.
Physics, chemistry & (micro)biology of food
In school you’re taught the main sciences (physics, chemistry & biology), when looking into food science these same disciplines return:
- Food chemistry, studying the molecules in food and how they react (for example: caramelization)
- Food (micro)biology, focusing more on the microorganisms in our food than on the actual growing of the plant
- Food physics, looking into the physical properties of food (for example: foams, frozen or gaseous foods)
Examples of applying food scienceThe apple example at the top of this page is just one example of applying food science around us. Let’s look at a few other examples:
- Example 1: French fries + mayonaise
- Mayonnaise is typical example of food physics being an oil-in-water emulsion. These normally split but mayonnaise does not, thanks to a physical phenomenon.
- The fact that you’re able to store a pot of mayonnaise at room temperature (before opening), has a lot to do with food microbiology.
- Frying french fries is food chemistry, starches react and your fries turns brown due to the Maillard reaction
- Example 2: Carrot cake
- The colours of carrot are pure food chemistry. They are made up by complex molecules.
- Baking the carrot cake will activate leavening agents (baking powder & baking soda), chemistry again.
- After some days of storage of the carrot cake, moulds may grow on it: food microbiology.
- If you then decide to whip up some cream to top off your carrot cake you end up in the field of food physics!
